Omron CQM1H series PLC, the memory card with the ability to backup DM data area of the data?
No, Omron PLC CQM1H series of its memory card can only backup program, DM (read-only data and PC settings) and extended instructions. If CJ1 series PLC can back up data DM data area.
PID module And PID instructions Which is better
PID instruction does not require PID hardware, it simply AD / DA input and output, but it takes up the PLC scan cycle; directly PID modules, without AD / DA's, and basically do not take up the scan cycle, but the need to invest in hardware costs, users are advised to consider the economic situation … Continue reading PID module And PID instructions Which is better

plc ladder switch tricks
PLC ladder, made to enter an inverted trapezoid, which is to complex, simple post, here is an inverted trapezoid diagram: The output is made positive trapezoid that briefly after complex. Writing good ladder, we must follow the above principles, the review does not meet the changes. First, draw the conventional logic circuit diagram, and then facing compile … Continue reading plc ladder switch tricks
Omron CP1 series PLC high-speed counter current value of how to maintain power?
Save power by PV PRV read to D, use INI instruction change PV power function, the D area data assignment back to PV. (Note: After the power failure, to ensure that the encoder does not rotate, otherwise the amount of rotation of the pulse will be lost).To maintain the high-speed counter 0 PV value

Omron PLC and Siemens touch screen Communication setting method
OMRON PLC can not communicate with TP177B / DP touch screen, But TP177A / DP and other communication with the screen (have repeatedly tested)Specific settings Communication Notes:(1) All communication settings (HMI and PLC) must be consistent (station number, baud rate, parity, etc., Use the default values here namely: "9600,7, Even / even, 2");(2) CPU-42H 4 feet should … Continue reading Omron PLC and Siemens touch screen Communication setting method
Omron PLC high-speed counter reset method
Omron PLC high-speed counting the number of reset mode, choose Z signal + software reset and soft reset in two ways. 1. Z signal + software reset mode High-speed counter reset flag is ON state, Z-phase signal and reset input OFF → ON time by the high-speed counter current value is reset. The case of … Continue reading Omron PLC high-speed counter reset method
