Is there a command to do a CRC check on a file?

No. Wouldn't be hard to do it in the PLC code though.

I thought of that Bob but it's a large binary file. I wouldn't want to have to read it all in just to do a CRC check. Feature request?

Program block with about 4 stages. Read 256 bytes at a time. Easy.

We use a modified BRX CPU as a test and programming station for production. Do a whole lot of stuff like this.
