Compactlogix Module Identity mismatch

3 posts in this topic

Could someone help me with this issue?

I have a compactlogix 1769-L18ER-BB1B with embedded 16 points I/O.

The processor is set to revision 20.14 but when I go to set up the embedded I/O to revision 20.14 and select Compatible Keying, I get a fault.

I went into the embedded I/O module and saw that the module identity is mismatch. Why is that?

I've attached a file of what I mean...

I think you need to go offline and change the number of expansion modules to equal 0, then download again.

The embedded I/O is defined when you create the 1769-L16 or -L18 project.    I've never had to do anything but leave it at the default settings.

With the revision of 1.0 and the 00000 serial number, that suggests to me that the embedded I/O might be damaged or defective right out of the box.
