CQM1 fatal error reset

4 posts in this topic

I have a fabric handling system using a CQM1-CPU21. When I started it , I got  error # 0x00F1. Also associated with it  are bits flagged AR1615 and AR1415.

I have the programming code on a PC.

I tried an error reset and now I have a stack of NOPs.

I am not seeing the IO table using CX-programmer.

Thank you.

AR 1415 ON: There is no program in the Memory Cassette or the program contains errors. Check the Memory Cassette.

Please look at the  section 2-1-2 DIP Switch in the above manual. What position are the switches in?
This will indicate if the program memory is being transferred or not.

You can change switch 1 and 2 off (with power off the PLC)
Power up the PLC. 
Transfer the PLC program using CX-Programmer.
Place in run mode.
Note: Your battery in this mode will protect your program.

Garry

That is now working well. However, I do not see the IO table in CX_Programmer.

3-1 CQM1 Memory Area Functions
3-1-2 IR Area
The IR memory area is a fixed location. It will depend on the order you attach the expansion cards. Their address will automatically be assigned. See the above sections in the manual. 
The CQM1 will not have an I/O Table that can be changed.
