Page 7: Precautions
PRECAUTIONS This section provides general precautions for using the Programmable Controller (PC) and related devices. The information contained in this section is important for the safe and reliable application of the Programmable Con- troller. You must read this section and understand the information contained before attempting to set up or operate a PC system. -
Page 8: Intended Audience
It is extremely important that a PC and all PC Units be used for the specified 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 PC System to the above-mentioned applications. -
Page 9: Operating Environment Precautions
Application Precautions • The PC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system. - Page 10 Application Precautions • Always turn OFF the power supply to the PC before attempting any of the fol- lowing. Not turning OFF the power supply may result in malfunction or electric shock. • Mounting or dismounting I/O Units, CPU Units, Memory Cassettes, or any other Units.

Page 15: Introduction
SECTION 1 Introduction This section describes the CPM2A’s special features and functions, shows the possible system configurations, and outlines the steps required before operation. Read this section first when using the CPM2A for the first time. Refer to the CPM1/CPM1A/CPM2A/CPM2C/SRM1(-V2) Programming Manual (W353) for details on programming opera- tion. - Page 16 The full complement of communications functions provide communications with personal computers, other OMRON PCs, and OMRON Programmable Termi- nals. These communications capabilities allow the user to design a low-cost dis- tributed production system.

CompoBus/S I/O Link CompoBus/S I/O Link Units can be connected to make the CPM2A a Slave De- Units vice in a CompoBus/S Network. The I/O Link Unit has 8 input bits (internal) and 8 output bits (internal).
- Page 18 CPM2A Features and Functions Section When used as pulse plus direction or up/down pulse outputs, there can be just one output with a frequency range of 10 Hz to 10 kHz. High-speed Input Capabilities for Machine Control High-speed Interrupt There are four inputs used for interrupt inputs (shared with quick-response in- Input Function puts and interrupt inputs in counter mode) with a minimum input signal width of 50 µs and response time of 0.3 ms.
