MM200 DPV1 diagnosis data is structured as shown below:
The extended diagnosis consists of Process Alarms and Diagnostic Alarms.
Trip, Alarm, and Control status are categorized as Process Alarms, as these provide
information pertaining to the Motor health that MM200 is controlling and monitoring.
Messages are categorized as Diagnostic Alarms as these provide detailed MM200
diagnostic information.
The detailed message layout explaining what information each bit provides is as follows:
DPV1 Composed
Address (hex)
0002 + 3000 = 3002
0007 + 3000 = 3007
0007 + 3000 = 3007
00B9 + 3000 = 30B9
011C + 3000 = 311C
020B + 3000 = 320B
DPV1 Composed
Address (hex)
00AB + 4000 = 40AB
011C + 4000 = 411C
0623 + 4000 = 4623
Cause
Wrong code was added to the slot. Ensure 3000H or 4000 was added
to the memory map address issued to the device.
An invalid memory area was defined. It can be caused by a base
invalid memory address or a request to read a reserved memory area.
Ensure the base address is correct and that a valid length was
specified.
