PRECAUTIONS This section provides general precautions for using the CP-series Programmable Controllers (PLCs) and related devices. The information contained in this section is important for the safe and reliable application of Programmable Controllers. You must read this section and understand the information contained before attempting to set up or operate a PLC system.
Page 24: Intended Audience
It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned appli- cations.
Page 25 Safety Precautions • The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. Unexpected operation, however, may still occur for errors in the I/O con- trol section, errors in I/O memory, and errors that cannot be detected by the self-diagnosis function.
Page 26: Operating Environment Precautions
Operating Environment Precautions !Caution When connecting the PLC to a computer or other peripheral device, either ground the 0 V side of the external power supply or do not ground the external power supply at all. Otherwise the external power supply may be shorted depending on the connection methods of the peripheral device.

Page 202 Timers and Counters Section 4-13 The refresh method for timer PVs can be set from the CX-Programmer to either BCD or binary. Note It is not recommended to use the same timer number in two timer instructions because the timers will not operate correctly if they are timing simultaneously. (If two or more timer instructions use the same timer number, an error will be generated during the program check, but the timers will operate as long as the instructions are not executed in the same cycle.)
Page 203: Counter Area (C)
Timers and Counters Section 4-13 4-13-2 Counter Area (C) The 4,096 counter numbers (C0000 to C4095) are shared by the CNT, CNTX(546), CNTR(012), CNTRX(548), CNTW(814), and CNTWX(818) instructions. Counter Completion Flags and present values (PVs) for these instructions are accessed with the counter numbers. When a counter number is used in an operand that requires bit data, the counter number accesses the Completion Flag of the counter.

Pulse Outputs Section 5-3 5-3-5 Origin Search and Origin Return Functions The CP1H CPU Units have two functions that can be used to determine the machine origin for positioning. 1,2,3... 1. Origin Search The ORG instruction outputs pulses to turn the motor according to the pat- tern specified in the origin search parameters.
Page 290 Pulse Outputs Section 5-3 5-3-5-1 Origin Search When ORG(889) executes an origin search, it outputs pulses to actually move the motor and determines the origin position using the input signals that indi- cate the origin proximity and origin positions. The input signals that indicate the origin position can be received from the servomotor's built-in phase-Z signal or external sensors such as photoelectric sensors, proximity sensors, or limit switches.
Page 291 Pulse Outputs Section 5-3 Procedure • Output: Connect the outputs using the CW/CCW method or pulse + direction method. The same method must be used for all of the pulse outputs.

Appendix E Memory Map PLC Memory Addresses PLC memory addresses are set in Index Registers (IR00 to IR15) to indirectly address I/O memory. Normally, use the MOVE TO REGISTER (MOVR(560)) and MOVE TIMER/COUNTER PV TO REGISTER (MOVRW(561)) instructions to set PLC memory addresses into the Index Registers. Some instructions, such as DATA SEARCH (SRCH(181)), FIND MAXIMUM (MAX(182)), and FIND MINIMUM (MIN(183)), output the results of processing to an Index Register to indicate an PLC memory address.
