Legacy Mode (Use Legacy Mode = Yes) - ProSoft Technology inRAx MVI56-PDPMV1 User Manual

Diagnostics and Troubleshooting
User Manual
As previously indicated in this User Manual the module requires the correct
sample program loaded to the processor for correct initialization and operation. If
the sample program is not correctly setup, then the module might not fully
initialize or allow access to the debug menu through PCB.
As indicated below, it is required to have a sample program loaded in the
processor in order to allow debug menu access through PCB and to be able to
reconfigure the MVI56-PDPMV1 module.
Also, if you observe the MSTR STAT LED as RED or blinking GREEN/RED it
means that an incorrect sample ladder logic was loaded to the processor (not
matching the actual module mode (LEGACY or FLEX).
The following tables will help you to troubleshoot different scenarios and the LED
behavior.
