Page 29: General Precautions
!Caution Confirm safety before transferring data files stored in the file memory (Mem- ory Card or EM file memory) to the I/O area (CIO) of the CPU Unit using a peripheral tool. Otherwise, the devices connected to the output unit may mal- function regardless of the operation mode of the CPU Unit.
Page 30 PLC to which is mounted a non-insulated Unit (CS1W-CLK12/52(-V1) or CS1W-ETN01) connected to an external power supply. A short-circuit will be created if the 24 V side of the external power supply is grounded and the 0 V side of the peripheral device is grounded. When connecting a peripheral device to this type of PLC, either ground the 0 V side of the external power supply or do not ground the external power supply at all.
Page 31: Application Precautions
• Locations subject to possible exposure to radioactivity. • Locations close to power supplies. !Caution The operating environment of the PLC System can have a large effect on the longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PLC System.
Page 32 • When storing the Power Supply Unit for more than three months, store it at 20 to 30 C and 25% to 70% humidity to preserve the Replace- ment Notification Function. • If the Power Supply Unit is not installed properly, heat buildup may cause the replacement notification signal to appear at the wrong time or may cause interior elements to deteriorate or become damaged.
Page 33 PRECAUTIONS • Do not apply voltages to the Input Units in excess of the rated input volt- age. Excess voltages may result in burning. • Always connect to a ground of 100 or less when installing the Units. Not connecting to a ground of 100 or less may result in electric shock.
Page 34 • A battery is mounted to a CJ-series CPU Unit when the Unit is shipped from the factory. Also, the time is set on the internal clock. It is thus not necessary to clear memory and set the clock before using a CJ-series CPU Unit.
Page 35 • If the I/O Hold Bit is turned ON, the outputs from the PLC will not be turned OFF and will maintain their previous status when the PLC is switched from RUN or MONITOR mode to PROGRAM mode.

An instruction may not be executed or may act differently depending on instruction conditions. Instruction conditions are reset (canceled) at the start of each task, i.e., they are reset when the task changes. CS/CJ/NSJ Series Instructions Reference Manual (W474)
Page 40 JME0(516) jump. Block program Executes a program block from BPRG(096) BEND(801) execution BPRG(096) to BEND(801). Flags In this context, a flag is a bit that serves as an interface between instructions. Input flags Output flags Flag Description Flag Description Carry (CY)
Page 41: Instruction Location And Execution Conditions
Note Operands are also called the first operand, second operand, and so on, start- ing from the top of the instruction. First operand Second operand Instruction Location and Execution Conditions The following table shows the possible locations for instructions.
Page 42 Input Instructions (Logical Starts and Intermediate Instructions): These instructions read bit status, make comparisons, test bits, or perform other types of processing every cycle. If the results are ON, power flow is out- put (i.e., the execution condition is turned ON).
Page 43 ■ Upwardly Differentiated Instructions (Instruction Preceded by @) Output Instructions: The instruction is executed only during the cycle in which the execution condi- tion turned ON (OFF ON) and are not executed in the following cycles. The instruction is executed only during the cycle in which the execution condi- tion turned ON (OFF ON) and are not executed in the following cycles.
Page 44 Note The downward differentiation variation (indicated by “%”) cannot be used with as many instructions as the upward differentiation varia- tion. It can be used only with the LD, AND, OR, SET, and RSET in- struction. To use downward differentiation with any other instructions, combine the instruction with the DIFD(014) or DOWN(522) instruc- tion.
Page 45 Input Instructions (Logical Starts and Intermediate Instructions): The instruction reads bit status, makes comparisons, tests bits, or perform other types of processing every cycle and will output an OFF execution condi- tion (power flow stops) when results switch from ON to OFF.

Page 47 • With both upwardly and downwardly differentiated instructions, outputs will turn OFF in the next cycle. Note Do not use the Always P_On Flag or A200.11 (First Cycle Flag) as the input bit for an upwardly differentiated instruction. Do not use the Always P_Off Flag as the input bit for a downwardly differentiated instruction.

Page 50 A constant or word address in I/O memory can be used for the offset. If a word address is speci- fied, the contents of the word is used directly as the offset.
Page 51 Note When specifying an indirect address in Binary Mode, treat Data Memory (DM) and Extended Data Memory (EM) (banks 0 to 18) as one series of addresses. If the contents of an address with the @ symbol exceeds 32767, the address will be assumed to be an address in the Extended Data Memory (EM) continuing on from 0 in bank No.

If there is no immediate refreshing specification, the status of the execution condition (power flow) is written to the specified bit in I/O memory. If there is an immediate refreshing specification, the status of the execution condition (power flow) is also written to the Basic Output Unit's output terminal in addition to the output bit in I/O memory.
Page 192 OFF. Precautions • With CJ2 CPU Units, OUT can be used for bits in the DM or EM Area. For other models of CPU Unit, OUT cannot be used for bits in the DM or EM Area. Use OUTB(534) instead.
Page 193 Function TR bits are used to temporarily retain the ON/OFF status of execution conditions in a program when programming in mnemonic code. They are not used when programming directly in ladder program form because the processing is automatically executed by the Peripheral Device. The following diagram shows a simple application using two TR bits.
Page 194 3. Instructions TR0 to TR15 Considerations TR bits are used only for retaining (OUT TR0 to TR15) and restoring (LD TR0 to TR15) the ON/OFF status of branching points in programs with many output branches. They are thus different from general bits, and cannot be used with AND or OR instructions, or with instructions that include NOT.

Page 196 • KEEP(011) has an immediate refreshing variation (!KEEP(011)). When an external output bit has been specified for B in a !KEEP(011) instruction, any changes to B will be refreshed when !KEEP(011) is executed and reflected immediately in the output bit. (The changes will not be reflected immediately if the bit is allocated to a Group-2 High-density I/O Unit, High-density Special I/O Unit, or a Unit mounted in a SYSMAC BUS Remote I/O Slave Rack.)
Page 197 • The status of I/O Area bits can be retained in the event of a power interruption by turning ON the IOM Hold Bit and setting IOM Hold Bit Hold in the PLC Setup. In this case, I/O Area bits used in KEEP(011) will maintain status after restarting the PLC following a power interruption, just like holding bits.
Page 198 KEEP (011) 1.00 Note KEEP(011) is input in different orders on in ladder and mnemonic form. In ladder form, input the set input, KEEP(011), and then the reset input. In mnemonic form, input the set input, the reset input, and then KEEP(011).
Page 199 Status of B 1 cycle Hint • UP(521) can be used to execute an instruction for just one cycle when the execution condition goes from OFF • DIFU(013) has immediate refreshing variation (!DIFU(013)). When an external output bit has been specified for B in this instruction, any changes to B will be refreshed when the instruction is executed and reflected immediately in the output bit.
Page 200 • The operation of DIFU(013) will not be consistent if the same subroutine is executed more than once in the same cycle. Sample program When CIO 0.00 goes from ON to OFF in the following example, CIO 10.00 is turned ON for one cycle. 0.00 DIFU 10.00...

Page 205 Flags Operand Description Data type Error Flag • ON if N1 is not within the specified range of 0000 to 000F (&0 to &15). • OFF in all other cases. Function SETA SETA(530) turns ON N2 bits, beginning from bit N1 of D, and continuing to the left N2 bits are set to 1 (ON).
Page 206 SETA(530). Hint SETA • SETA(530) can be used to turn ON bits in data areas that are normally accessed by words only, such as the DM and EM areas. RSTA • RSTA(531) can be used to turn OFF bits in data areas that are normally accessed by words only, such as the DM and EM areas.
Page 207 Flags Operand Description Data type Error Flag • ON if N is not within the specified range of 0000 to 000F (&0 to &15). • OFF in all other cases. Function SETB SETB(532) turns ON bit N of word D when the execution condition is ON.
Page 208 • Differences between SET/RSET and SETB(532)/RSTB(533) The instructions operate in the same way when the specified bit is in the CIO, W, H, or A Area. The SETB(532) and RSTB(533) instructions can control bits in the DM and EM Areas, unlike SET and RSET.

• MULTI-INTERLOCK DIFFERENTIATION RELEASE and MULTI-INTERLOCK CLEAR (MILR(518) and MILC(519))* Note MILR(518) does not hold the status of the Differentiation Flag, so differentiated instructions that were inter- locked are not executed after the interlock is cleared. • These instructions are supported only by CS/CJ-series CPU Unit Ver. 2.0 or later and CJ2 CPU Units.
Page 212 IL(002) and ILC.(003). MILH Note The different interlocks (IL-ILC, MILH-MILC, and MILR-MILC) can be used together as long as the inter- locked program sections do not overlap. For example, all three interlock methods can be used without overlapping, as shown in the following diagram.
Page 213 3. Instructions Differences between Interlocks and Jumps The following table shows the differences between interlocks (created with IL(002)/ILC(003), MILH(517)/MILC(519), or MILR(518)/MILC(519)) and jumps created with JMP(004)/JME(005).

Page 215 No flags are affected by NOP(000). Function • No processing is performed for NOP(000), but this instruction can be used to set aside lines in the program where instructions will be inserted later. • NOP(000) can only be used with mnemonic displays, not with ladder programs.
Page 216 Unchanged *1 In CJ2, CS1-H, CJ1-H, CJ1M, and CS1D (for Single-CPU System) CPU Units, the Equals and Negative Flags are left unchanged. In CS1D CPU Units for Duplex Systems, CS1 CPU Units, and CJ1 CPU Units, these are turned OFF.
Page 217 • In general, IL(002) and ILC(003) are used in pairs, although it is possible to use more than one IL(002) with a single ILC(003) as shown in the following diagram. If IL(002) and ILC(003) are not paired, an error message will appear when the program check is performed but the program will be executed properly.

Page 220 BOOL N: Interlock Number The interlock number must be between 0 and 15. Match the interlock number of the MILH(517) (or MILR(518)) instruction with the same number in the corresponding MILC(519) instruction. The interlock numbers can be used in any order.
Page 221 3. Instructions Function When the execution condition for MILH(517) (or MILR(518)) with interlock number N is OFF, the outputs for all instructions between that MILH(517)/MILR(518) instruction and the next MILC(519) with interlock number N are interlocked. When the execution condition for MILH(517) (or MILR(518)) with interlock number N is ON, the instructions between that MILH(517)/MILR(518) instruction and the next MILC(519) with interlock number N are executed normally.

Page 225 3. Instructions Hint • The cycle time is not shortened when a section of the program is interlocked by MILH(517) or MILR(518) because the interlocked instructions are executed internally. • When nesting interlocks, assign interlock numbers so that the nested program section does not exceed the outer program section.
Page 226 Note The MILR(518) interlocks operate in the same way if there is another MILH(517) or MILR(518) instruction with the same interlock number between an MILR(518) and MILC(519) pair. • If there is an MILC(519) instruction with a MILH When input condition "a"...
Page 227 ... • If there are bits which you want to remain ON in a program section interlocked by MILH(517) or MILR(518), set these bits to ON with SET just before the MILH(517) or MILR(518) instruction. CS/CJ/NSJ Series Instructions Reference Manual (W474)
Page 228 3. Instructions Sample program When W0.00 and W0.01 are both ON, the instructions between MILH(517) with interlock number 0 and MILC(519) with interlock number 0 are executed normally. When W0.00 is OFF, the instructions between MILH(517) with interlock number 0 and MILC(519) with interlock number 0 are interlocked.

Page 230 • Because all of instructions between JMP(004)/CJP(510)/CJPN(511) and JME(005) are skipped when the execution condition for JMP(004) is OFF, the cycle time is reduced by the total execution time of the skipped instructions. In contrast, processing time equivalent to NOP(000) processing is required for instructions between JMP0(515) and JME0(516), so the cycle time is not reduced as much with those jump instructions.
Page 231 JME &1 • JMP(004) and JME(005) pairs must be in the same task because jumps between tasks are not allowed. An error will occur if a JME(005) instruction is not programmed in the same task as its corresponding JMP(004) instruction.
Page 232 • ON if there is a CJP(510) or CJPN(511) instruction in a task without a JME(005) with the same jump number. • OFF in all other cases.

Page 233 Hint • In the case of a JMP, CJP, or CJPN instruction, the program jumps directly to the JME instruction when the jump condition is satisfied. An instruction is not executed between JMP/CJP/CJPN and JME, and thus instruction execution time is not needed in that interval. Therefore, cycle time is reduced.
Page 234 OFF (CJP(510)) or ON (CJPN(511)). A Cycle Time Too Long error will occur if the jump is not completed by changing the execution condition executing END(001) within the maximum cycle time.

Page 244 In this example, a TIM instruction and a CNT instruction are combined to make a 500-second timer. TIM 0001 generates a pulse every 5 s and CNT 0002 counts these pulses. The set value for this combination is the timer interval counter SV.
Page 245 In this example two TIM timers are combined with KEEP(011) to make an ON delay and an OFF delay. CIO 5.00 will be turned ON 5.0 seconds after CIO 0.00 goes ON and it will be turned OFF 3.0 seconds after CIO 0.00 goes OFF.
Page 246 Example 4: One-shot Bit A TIM timer can be combined with OUT or OUT NOT to control how long a particular bit is ON or OFF. In this example, CIO 2.04 will be ON for 1.5 seconds (the SV of T0001) after CIO 0.00 goes ON.
Page 247 • Timer and counter numbers can be indirectly addressed using Index Registers. When Index Registers will be used for indirect addressing, use MOVRW(561) (MOVE TIMER/COUNTER PV TO REGISTER) to set the PLC memory address of the desired timer or counter's PV to the desired Index Register.
Page 248 1. Use the TIMER RESET Instruction. The specified instruction will be reset when the TIMER RESET instruction (TRSET) is executed. TRSET can be used to reset only one timer at a time, but it is faster than the RESET TIMER/COUNTER instruction (CNR/CNRX).
Page 249 The specified instruction will be reset when the RESET TIMER/COUNTER instruction (CNR/CNRX) is executed. More than one timer can be reset at the same time for CNR/CNRX, but more time is required than for TRSET. CNR/CNRX is used in the same way as TRSET.

For example, if 12 bits (4 hex) is designated for the input range, the range from 0000 hex to 0FFF hex will be enabled as the PV.
Page 671: Performance Specifications
• The upper and lower limits of the manipulated variable output can be designated. • The sampling period can be designated in units of 10 ms (0.01 to 99.99 s), but the actual PID action is determined by a combination of the sampling period and the time of PID(190) instruction execution (with each cycle).

Page 674 3. Instructions Note 1 When the unit is designated as 1, the range is from 1 to 8,191 times the period. When the unit is designated as 9, the range is from 0.1 to 819.1 s. When 9 is designated, set the integral and derivative times to within a range of 1 to 8,191 times the sampling period.
Page 675 MV is made proportional to the deviation (the difference between from SV and PV) and gradually decreased until the SV and PV match (i.e., until the deviation is 0), at which time the MV will be at the minimum value of 0% (or 50%, depending on the setting of the manipulated variable output designation parameter).
Page 676 The strength of the derivative action is indicated by the derivative time, which is the time required for the manipulated variable of the derivative action to reach the same level as the manipulated variable of the proportional action with respect to the step deviation, as shown in the following illustration.
Page 677 3. Instructions Direction of Action When using PID control, select either of the following two control directions. In either direction, the MV increases as the difference between the SV and the PV increases. • Forward action: MV is increased when the PV is larger than the SV.

Page 683 • When changing the PID constants manually, set the PID constant change enable setting (bit 1 of C+5) to 1 so that the values in C+1, C+2, and C+3 are refreshed each sampling period in the PID calculation. This setting also allows the PID constants to be adjusted manually after autotuning.

Page 895 3. Instructions In order to communicate through the network, it is necessary to register a routing table in each PLC's CPU Unit which indicates the route by which data will be transferred to the desired node. Each routing table is made up of a local network table and a relay network table.
Page 896 Communications from a Host Computer Connected through Host Link It is possible to send FINS commands from a host computer to the PLC to which it is connected as well as other devices in the network (CPU Units, Special I/O Units, computers, etc.). In this case, the necessary Host Link header and terminator must be attached to the FINS command when it is sent.
Page 897 Network Communications Instructions With CS/CJ-series PLCs, up to eight Network Communications Instructions can be executed simultaneously. With CJ2-series PLCs, up to 64 Network Communications Instructions can be executed simultaneously for some instructions. These instructions are called CJ2 Network Communications Instructions.

Page 900 Each communications port can be used by only one instruction at a time. To specify a communications port, the following steps were necessary. • When programming, it was necessary to keep track of the ports that were being used to designate only available ports in operands.

Page 902 A219 b (port) c (Standby) turns OFF in the cycle after communications instruction execution is completed and communications completion are detected from that cycle. CS/CJ/NSJ Series Instructions Reference Manual (W474)
Page 903 The communications port can be specified in the control data of the Network Communications Instruction. The same communications port cannot be used in any other instruction until processing this instruction has been completed. Exclusive control of the communications port is necessary.
Page 904 Application Methods 1. Set the communications port in the instruction operand to 0 to 7 hex. 2. Use the Communications Port Enabled Flag (A202.00 to A202.07) to perform exclusive control of the communications port. Bit A remains ON while the communications KEEP A instruction is being executed.
Page 905 Each flag will turn ON for just one cycle after a communications error occurs. Bits 00 to 07 correspond Network Communications to ports 0 to 7. If the flag turns ON, refer to the Communications Port Completion Code in (A203 to Error A210) to identify the cause of the error.

Page 907 3. Instructions Accessing the Completion Code after Executing Communications Instructions The completion codes are generally used to troubleshoot errors when they occur. A completion code of 0000 hex can, however, also be used to confirm that communications have been completed normally.
Page 908 ,IR0 #0000 2 If it is possible that more than eight communications instructions will be executed at the same time, always check to be sure there is an available communications port before executing a communications instruction, even when using automatic port allocation.
Page 909 3 It is acceptable to specify the communications port for some communications instructions and use automatic port allocation for others. It is possible, however, that a port specified by the user for one communications instructions may have already been automatically allocated. You must therefore be careful when adding communications instructions that use automatic port allocation to existing ladder diagrams, as shown below.
Page 910 Methods for Using Explicit Message Communications There are two methods that can be used to send explicit messages from a PLC. • Use the CMND(490) or CMND2(493) to send a FINS command code of 2801 hex (EXPLICIT MESSAGE SEND). • Use the following Explicit Message Instructions. (See note.) Note These instructions are supported only by CS/CJ-series CPU Unit with unit version 2.0 or later.
Page 911 For error completions (i.e., when the flag is ON), the Communications Port Error Flag for FINS commands is used to determine if the explicit message was never sent (i.e., when the flag is ON) or if there was an error in the explicit message that was sent (i.e., when the flag is OFF).
Page 912 There are two possibilities for error ends, as described in the next two subsections. a) When the Explicit Message Could Not Be Sent In this case, the explicit message was never sent on the network, e.g., because the network was not running. Here, both the Explicit Communications Error Flag (A213.00 to A213.07: Communications ports 0 to 7) and the Communications Port Error Flag (A219.00 to A219.07: Communications ports 0 to...
