Steps for correct power off and power on of DCS
DCS power off correctly When the DCS needs to be powered off for maintenance due to overhaul or other reasons, we often directly power off the DCS, but sometimes this non-standard operation will bring serious consequences, such as configuration loss, PID parameter loss, etc. Therefore, it is nece...Read more -
How to distinguish large, medium and small PLC?
There are many kinds of PLC products, and their specifications and performance are also different. The classification of PLC is generally based on the difference of its structure, function and I/O points. 1. Classification by I/O points (1) Small computer. The total number of input and output poi...Read more -
PLC controller’s main anti-interference measures
For the PLC controller power supply, should use non-power line power supply, directly from the low-voltage distribution room on the main bus using a special line power supply. Choose isolation transformer, and transformer capacity should be larger than the actual needs of about 1.2 to 1.5 times, ...Read more -
