Page 63: Shielding Of Devices And Cables
Installation Guidelines S5-100U 3.4.2 Shielding of Devices and Cables Shielding is a means of weakening or damping magnetic, electrical, or electromagnetic interference fields. Both devices and cables should be shielded. Shielding of Devices Use the following information if cabinets and housing are used in shielding the control system.
Page 64: Measures To Guard Against Electromagnetic Interference
S5-100U Installation Guidelines Shielding Cables Both ends of shielded cables should have a good electrical connection to the cabinet's chassis ground. You can effectively suppress interference of all coupled frequencies only if the cables are shielded at both ends. The shield should reach the module, but it should not be connected to the module.
Page 65 Installation Guidelines S5-100U Chassis Grounding of Inactive Metal Components Correct chassis grounding is an important factor in ensuring that you won't experience interference problems. Chassis grounding refers to the conductive connection of all inactive metal components (VDE 0160). Always use surface-contact grounding. Chassis-ground all inactive metal components.
Page 66 S5-100U Installation Guidelines Using Special Interference Suppression Measures Protective Inductive Circuit Inductors located in the same cabinet and not directly controlled by SIMATIC outputs (e.g., contactor coils and relay coils) must be bridged by arc suppressing elements (e.g., RC elements).
Page 67 Installation Guidelines S5-100U Power Connection for Programmers Every group of cabinets should have a grounded socket for the power supply to the programmers. The sockets should receive their power supply from the distributor that is also connected to the cabinet's protective ground.

DB0 is reserved for the operating system, DB1 for setting parameters for internal functions (see section 9.1).
Page 138: Program Processing
• OBs for (process) interrupt-driven program processing The S5-100U has additional OBs whose functions are similar to those of integral function blocks (e.g., PID control algorithm). These OBs are described in chapter 9. Section 7.3.1 summarizes all of the OBs.
Page 139 S5-100U Introduction to STEP 5 7.4.1 Program Processing with CPU 102 You can process the program in the following two modes: • Normal mode • Test mode Program processing is faster in the normal mode, but you can not use the STATUS test function.
Page 140 Introduction to STEP 5 S5-100U Special Features of the Normal Mode Significance of the Memory Submodule Normal mode is only possible if the memory submodule is plugged in. This submodule contains only the STEP 5 program. The CPU RAM contains the STEP 5 program and the compiled program to be processed.

Introduction to STEP 5 S5-100U 7.4.3 Cyclic Program Processing The operating system calls OB1 cyclically. If you want to have structured programming, you should program only jump operations (block calls) in OB1. The blocks you call up, PBs, Cycle trigger FBs, and SBs, should contain completed functional units in order to provide a clearer overview.
Page 147 S5-100U Introduction to STEP 5 Response Time Response time t is defined as the time between a change in the input signal and the subsequent change in the output signal. Prerequisites for the following information: • No interrupts are running.
Page 148: Time-Controlled Program Processing, For Cpu 103 Version 8Ma02 And Higher
Introduction to STEP 5 S5-100U 7.4.4 Time-Controlled Program Processing, for CPU 103 Version 8MA02 and Higher Time-controlled program processing can be defined as a (periodic) time signal causing the CPU to interrupt cyclic program processing to process a specific program. Once this program has been processed, the CPU returns to the interruption point in the cyclic program and resumes processing.
Page 149: Version 8Ma02 And Higher
S5-100U Introduction to STEP 5 • Reading out the interrupt PII When OB13 is called, the signals of the input modules are read into the interrupt PII. The interrupt PII can be scanned in OB13 by means of the L PB 0 to 127 or L PW 0 to 126 load operations (load byte x or word x of the interrupt PII in ACCU 1).
Page 150: Processing Blocks
Introduction to STEP 5 S5-100U Processing Blocks Earlier sections in this chapter described how to use blocks. Chapter 8 introduces all of the operations required to work with blocks. You can change any block that has been programmed. The following sections will deal only briefly with the different ways you can change blocks. Refer to the operator‘s guide for your programmer for more detailed information on changing blocks.
Page 151: Number Representation
S5-100U Introduction to STEP 5 You can use the COMPRESS programmer function to clean up internal program memory. If there is a power failure during the compress operation when a block is being shifted and block shifting can not be completed, the CPU remains in the STOP mode. The “NINEU” error message appears.
Page 152 Introduction to STEP 5 S5-100U You can work with binary-coded decimals to program timers and counters in the decimal system. BCD tetrads are defined in the range of 0 to 9. Example: 12-bit timer or counter value in BCD and decimal formats Word No.
Page 153 S5-100U Introduction to STEP 5 You can use the “LC” operation to convert a binary number to a BCD number for timers and counters. Example: Comparing a count in counter 1 with decimal number 499 The comparison value must be stored in the accunulator by means of a load operation.

S5-100U STEP 5 Operations 8.1.2 Set/Reset Operations Set/reset operations store the result of logic operation (RLO) formed in the processor. The stored RLO represents the signal state of the addressed operand. Storage can be dynamic (assignment) or static (set and reset). Table 8-2 provides an overview of the set/reset operations. Examples follow the table.
Page 163 STEP 5 Operations S5-100U Flip-Flop for a Latching Signal Output (reset dominant) Example Circuit Diagram A “1” at input I 0.1 sets flip-flop Q 1.0 (signal state “1”). If the signal state at input I 0.1 changes to “0”, the state of output Q 1.0 is maintained, i.e., the signal is latched.

Examples follow the table. Table 8-4. Overview of Timer Operations Operation Operand Meaning Pulse Timer The timer is started on the leading edge of the RLO.
Page 171 STEP 5 Operations S5-100U Loading a Time Timer operations call internal timers. When a timer operation is started, the word in ACCU 1 is used as a time value. You must therefore first specify time values in the accumulator. You can load a timer with any of the following data types:...

Page 174 S5-100U STEP 5 Operations Starting a timer In the programmable controller, timers run asynchronously to program scanning. The time that has been set can run out during a program scanning cycle. It is evaluated by the next time scan. In the worst case, an entire program scanning cycle can go by before this evaluation.

Page 302: Structure Of The Clock Data Area
The Integral Real-Time Clock S5-100U 12.4 Structure of the Clock Data Area You need only to change the default values in DB1 to program the clock in DB1. See section 12.2. During start-up, the DB1 interpreter writes all information into the system data area.
Page 303 S5-100U The Integral Real-Time Clock When you set the clock, you have to transfer only the data needed to implement a particular function. For example, if you want to change only the clock function data, you do not have to enter data for the time prompt function or for the operating hours counter.
Page 304 The Integral Real-Time Clock S5-100U Make certain you are aware of the following points when you make inputs into the clock data area. • Entries into the clock data area must be in BCD code. • The clock runs either in the 12-hour mode or the 24-hour mode depending on how you set bit 1 in the status word.
Page 305 S5-100U The Integral Real-Time Clock If your inputs differ from the ones described, the operating system outputs error messages that are displayed in the status word. The operating system resets error messages displayed in the status word the next time you set the clock, prompt time, or the operating hours counter, if the new settings are within the definition range.

Page 428: Functional Description Of The Counter Mode
Function Modules S5-100U 15.6.3 Functional Description of the Counter Mode In the operation mode “Counter”, the module works as a “port-controlled” up-counter and counts the positive edges of the counting pulses while the enable input is active. If the counter reaches a preselected setpoint, the respective output is enabled.
Page 429 S5-100U Function Modules Disabling the Counter A negative edge at the enable input disables the counter. The outputs, diagnostic bits, and the counter are not reset. You can continue reading the current count. A positive edge at the enable input resets the outputs and the diagnostic bytes.
Page 430: Functional Description Of The Position Decoder
Function Modules S5-100U Performance during Overflow If the enabled counter exceeds the counter range limit 65,535 the following occurs: • Bit 3 (overflow) in the diagnostic byte is set to “1”. • The outputs and diagnostic bits for “setpoint reached” are disabled, but they remain unchanged.
Page 431 S5-100U Function Modules Connect the sub-D interface female connector to an incremental position encoder that has to deliver the following signals: • Two counting pulses offset by 90 degrees • A reference pulse The pulses can be supplied as 5-V differential signals according to RS 422 (up to 500 kHz) or as 24-V DC signals.
Page 432 Function Modules S5-100U Example: A rotary incremental position encoder produces 1000 pulses per revolution. The spindle has a pitch of 50 mm/revolution. The position encoder therefore produces 1000 pulses for a traversing path of 50 mm (1 revolution). The resolution of the encoder is therefore 50 mm/1000 pulses.
Page 433 S5-100U Function Modules Prerequisites for a Synchronization • The reference signal The sensor for the reference signal is connected to terminals 7 and 8 of the terminal block. Synchronization is enabled with the leading edge (0 to 1) at terminal 8. If the signal was already on “1”...

Page 435 S5-100U Function Modules Starting the Counter The counter is reset and started by setting the SYNC bit in the diagnostic byte during the reference point approach operation. The active pulses are counted according to the rotation direction of the position encoder. The count value is incremented during a positive count direction, and decremen- ted during a negative count direction.

Page 438 Function Modules S5100U Performance during Overflow If the counter leaves the counting range of -32768 to + 32767, then the following occurs: • Bit 3 (overflow) in the diagnostic byte is set to “1”. • The outputs of the counter module are disabled. The enable input (terminal 4 of the terminal block) must be set to “0”, in order to switch off active outputs.
