Gents,
We had to replace an CJ1G cpu for an CJ2M to get an Ethernet port on a machine.
I uploaded the PLC program including memory area, and changed the CPU type in the software.
I'm using the trail version of the CX-Programmer.
After replacing the CPU, I downloaded the converted program.
But now the machine will not run because of an F457 ( floating Point Divide ) Function doesn't calculate or gives an error.
The calculation is 32400 divide by 60 and returns with 0.000000 in D256
I had a chat with the Omron helpdesk, emailed the program, and when they do a simulation, everything works fine.
Unfortunately they could not tell me why it isn't working in the PLC program at the machine.
I also tried to replace the F457 with a MOVF where I move 540 into D256.
The strange thing is that this instruction also gives a 0 when monitoring D256.
Anyone an idea?
