Converting Omron c28k program to cp1e

blima · Jun 22, 2017

Hello!

I'm working in upgrading an old c28k Omron to a cp1e.

My doubts are concerning the IO pins. I can see in syswin 3.4 the following inputs:
0.0 to 0.15 so I should convert it to 0.0 to 1.4. Correct?

Regarding the outputs, on the PLC they are marked 100, 101, 102 and so on, but on the program I can only see coils starting at 1.0, 1.1, 1.2. Should I assume that they are the outputs and convert them to 100.0, 100.1, and so on.

Thanks
Bruno

Inputs for the CP1 go 0.00 - 0.11 then 1.00 - 1.11 etc.
Outputs go 100.00 - 100.07 then 101.00 - 100.07 etc.

Addressing:
The K series PLCs used a fixed address system. A maximum of 10 16-bit registers could be used for each CPU unit for the expansion I/O units added.
Example:
C28K-CDR-A (CPU 16 DC inputs / 12 relay outputs) + C20P-EDR-A (Expansion 12 DC inputs / 8 relay outputs)
Channel 0 – Address 000.00 to 000.15 – 16 DC inputs CPU
Channel 1 – Address 001.00 to 001.11 – 12 Relay outputs CPU
Channel 2 – Address 002.00 to 002.11 – 12 DC inputs Expansion
Channel 3 – Address 003.00 to 003.07 – 8 Relay outputs Expansion

Note: You are correct. Outputs marked 100 on the C28K represent 1.00. They would convert to 100.00

The CP1 has the following I/O address locations.
Input Area - 0.00 to 16.15
Output Area - 100.00 to 116.15

The above links will also point to the manuals of each controller.

CP1 has 12 inputs per channel only - 0 to 11 and 8 outputs per channel - to 7 only.

Thanks for all the inputs, but this one was very good.

I have finished the upgrade and in fact is quite odd for me that in this old PLC the outputs are similar to the inputs! I had to use tags to avoid been confused with it.

Thanks again,
Bruno
