Introduction In order to ensure the reliability and security of the system, prior to the design of the system it is important to make certain that the conditions in which it will be installed is well understood. Basically, the stresses on the PLC system (temperature, humidity, vibrations, shocks, corrosive gases, overcurrent, noise etc.) need to be reduced as much as possible. However, the extent to which measures need to be taken in this regard will depend upon the likelihood of problems arising, the conditions in which the system is installed, and the cost of implementing measures. By taking advanced measures to prevent problems, the reliability of the system can be improved, and in the long-term the operation rate can also be increased. For the individual specifications of each unit, please see the respective user manuals. Installation/Conditions of PLC Control Panel The following describes the environmental conditions and measures to be taken for the installation of th...

What is the OMRON PLC-based Process Control? OMRON PLC-based Process Control system is based on the SYSMAC CS/CJ PLC Series. By adding PLC-based Process Control units to the basic system configuration, PLC process control functions can be simply added on to the basic functions already installed in the PLC. Thus, it can be used for devices that it is compatible with such process control system in which DCS was used before or devices in which several controllers were used combined. With the PLC Installation System, analog processing is carried out by the loop control section or the loop control unit/board (hereafter "loop controller"), and ladder processing is handled by the CPU. Communication between the two sections is made using bits of memory. Since the analog processing and ladder processing can be completely separated and the program is more simple than a ladder only program, the engineering process to construct the system is facilitated. System configuration o...

PLC Basic Introduction This guide will describe the terminology needed for basic operation of the SYSMAC PLC (Programmable Controller), for clients new to our PLCs. This guide does not cover technical details regarding the setting of the FA System or PLC programming after purchase. I/O Refresh With the PLC (Programmable Controller), commands from user programs designed by the client are executed one by one and processed by reading and writing information in the internal PLC memory area (At OMRON, we call this the "I/O Memory"). At the same time, packages of data from sensors/switches that are directly connected to the basic I/O unit are exchanged with data in the PLC internal I/O Memory, at specific times. This process to totally exchange external data and internal I/O Memory data is called "I/O Refresh Operation". It is important to know the timing by which the I/O Refresh will be executed when considering the operation of the FA System and User ...
