Hi to all,

I have a project to upgrade an existing Omron plc, C28k, into CP1E. The original backup program copy is available. I need some assistance on the following issues;

1. There is a code in C28K, which is MPRF, but not in CP1E. Checking the list of instructions in CP1E, it seems the replacement is the IORF. Am I correct to use this instruction?

2. There is a analog timer module, C4K-TM. I tried looking for any manual in the web, but no luck. I wanted to know, how this analog timer works, so that I could modify the program code. Could somebody point me in the correct link, to be able to download the manual.

3. On the HMI side, the existing NT21-ST121-E, will be replaced with NB series HMI. I just noticed the tag address being used in NT. It is like bit address = D0001207, and when I searched in the program, there is no address matched. If I just take the last 3 remaining digit, there is a similar bit address. So, is D0001207 is just D2.07?

Thank you for your feedbacks.

Regards.

Hi Leo,

1 - There was not instruction in the K series named MPRF. This could have been IORF(97) - I/O REFRESH. Please look at the function code for the number. This number may have been interpreted incorrectly by the software that you used to download the program.

2 - This analog timer modal sets a time from 0.1 sec to 10 minutes. There are 4 channels to view. You can find this in section 1-1-3 Analog Timer Unit.

3. The NT21-ST121-E came out long after the C28K PLC. Communication happens by setting up a block of DM areas in the PLC to communicate. Everything gets passed through this block of DMs. Please refer to the following manual:

You must have a host link unit attached to the C28K CPU. A RS232 Cable (25pin) from the host link to the NT21 port (9pin). Interesting combination.

Hi Garry,

Thanks for the links, I've already downloaded the files and will get the information I need.
