Error in PM564 CPU
We are using PM564 for our project. but after some time PLC will automaticaly goes to stop mode and Error LED is continously blinking, and we can't go online with CPU.
this problem rise in lot of PLCs. due to this we are suffer a lot. as well as clients are facing problems because of this.
So is if any Hardware fault or we miss some step of programing?
we are using latest version of hardware and Software (Automation Builder 1.2 and Hardware firmware version 2.5.1)
is any solution available fo this problem?
First, if there were no problems or reports during the compilation, it seems to exclude the programming error. You should connect with your pc and check the error code that appears when the problem happens, just so you can give some advice on how to resolve
Hope this help you, let us know about the results
you have probably an E2 error. By default, the PLC stops and you can log in to find out the reason. It can be access to wrong memory areas (by pointer) or overload.
You have to check your PLC configuration. Stop the PLC in case of E2 should be configured, also a watchdog in case of too long task cycle.
Also a problem can be power supply. If the power is too low for proper operation, but not switched off completely, the PLC will as default reaction stop to work. You can configure that it performs a "warmstart" instead.
