Addressing Question CMP1A-40CDR-A-V1

3 posts in this topic

I have a PLC that i just had to replace the old PLC was an Omron FA-350A the new PLC is a CMP1A-40CDR-A-V1. The programs are almost identical however there are some I/O changes that will need made. I am used to allen bradley PLC's and this is my first time using CX-Programmer. The PLC came preloaded with what was supposed to be the correct program although almost all of the I/O was programmed to the same addresses. I have no idea how the Addresses are structured. Would anyone be able to explain them or point me to a resource. There are also some 200.XX addresses are those bit storage locations? Thank you, Mike

I suggest you download a copy of the CPM1A manual (W228) from the Omron website. Inputs on the CPM1A begin at 0.00 and go 9.15. Outputs begin at 10.00 and go through 19.15. 200.00 through 231.15 are internal bits that can be used for anything.

As per pervious post.... adding a little more info on the front of the PLC you will also notice the assigned addresses for the IO on the PLC. you will notice 0ch 1ch for inputs and 10ch, 11ch for outputs. ie as above post.. for inputs Channel 0 first input group addr 000.00, 000.01 --- through 000.11 next inpuut group Channel 1 then 001.00, 001.01 --- through 001.11 same syntax for outputs Channel 10 010.00, 010.01 --- through 010.07 Channel 11 011.00, 011.01 --- through 011.07
