Control area address within the value set for the NT 0000, you can write a program in the PLC program as follows:
Cause: indicates that the network communication timeout. Countermeasures: ① Check the main station must use the same baud rate from the station; ② Check the wiring of communication cable is loose; ③ whether the two terminals of the network terminating resistor; ④ check the current speed and distance network, consider reducing the baud rate of the network, using 125Kbps … Continue reading Omron DRM21 module prompts E2 error, how to do?
Reason: registered in the scan list from the station does not exist or is a local master node number is registered in the scan list of the master station. Countermeasures: ① initial commissioning or increase / decrease the slave node: a. Check the baud rate from the master station, you need to set the same;b. Using CX-Integrator software … Continue reading Omron DRM21 module prompts D5 error, how to do?
First, the Mitsubishi inverter must have a communication function, and then the inverter communication protocol must be open, the PLC Omron C200Ha plus a support plate communications protocol macro function with macro protocol to communicate.
Can, in general, the drive can be controlled in various ways, such as using analog output control inverter, OMRON CQM1H or use the protocol macro function of the inverter communication control, but requires the drive belt 422/485 communications port, If the drive supports DEVICENET protocol, it can also be linked directly into our COMPOBUS / … Continue reading How do Omron CQM1H and Delta inverter communication
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 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
1, Q: What kind of floating-point advantage in the result of the operation, he is not a small point and carry bit? Floating point and double precision floating point, what kind of difference?A: decimal floating point arithmetic with support, which is its advantage, floating-point operations per participation operations accounted for two-channel and double precision floating … Continue reading Omron PLC Failure Analysis and Troubleshooting
Omron PLC and other instruments or communications equipment (whether OMRON instruments or third-party instrumentation), with the use of serial communication protocol macro module or template, for the corresponding procedures according to the instrument or device communication protocol, establish the appropriate communication channel, it the instrument can read and write. I worked with third-party customers for over-temperature … Continue reading Omron PLC and temperature meter 485 serial communication realization
