Title: GSREGWR Errors with 2.7.1 upgrade
Post by: Bolt on March 31, 2020, 11:55:24 AM

I've had some GSREGWR instructions for years.  I think they worked as intended.  Now with my latest update, I get an error message that a few of the parameters should be a Modbus Write instead of a GSEDrive Write?  What gives?  For now I deleted the 2 offending rows, but something's still different.  Please clarify.

Yes.  P9.x parameters are not write-able via GSREGWR since those are communication parameters.  It never reported an error, but the values never got written either, so the logic was always "not working".

If you do need to configure specific Comm parameters at startup, use MWX and write to those parameters via Modbus.  GSREGWR uses the "block transfer" method, which dis-allows P9.x parameters.  If you use Modbus, you are by-passing that GSDrive "block transfer" mechanism.

Okay, thanks.  That's why I said I "think" they worked as intended.
