NJ to CJ CIP messaging

3 posts in this topic

Hello,

Wondering if anybody here has done CIP messaging between NJ and CJ controllers. I checked a bunch of manuals but they are pretty vague and I can't seem to be able to figure it out.

I tried CIPRead, CIPWrite, CIPUCMMRead and CIPUCMMWrite but I always get ErrorID 1C00 and ErrorIDEx 05000000.

I'm guessing it has to do with addressing the memory on the CJ, which I'm not very familiar with.

Some help would be much appreciated.

Thanks!

You need to know what you are asking the CJ for, so yes, you need to know the CJ memory map.

The commands are actually quite simple as long as you make the proper route path.

Thanks Crossbow,

You're right, it differs a little from addressing a NJ/NX. I got instructions from Omron support and got it working.
