Learn how to diagnose any ProSoft communication issue with these simple steps. I am demonstrating how to debug a Modbus TCP communication issue and what are the gotchas.
We will be using the ProSoft Configuration Builder in-build diagnostics tools to perform the communication diagnostics.

This technique can be used for all Prosoft with Ethernet ports; such as MVI56-Serial, MVI56-SMGC, MVI56-Serial, MVI56-101S, MVI56-EGD, MVI56-EGD, MVI56-Ethernet, MVI56-104S, MVI56-Serial, MVI56-BAS, MVI56-Serial, MVI56-S3964R, MVI56-Serial, MVI56-DNP, MVI56E-Ethernet, MVI56E-MNETCR, MVI56-PDPS, MVI56-PDPS, MVI56E-MNETC/MNETCXT, MVI56E-MNETC/MNETCXT, MVI56E-Ethernet, MVI56E-MNETR, MVI56E-GSC and MVI56E-GSC/GSCXT
