Issue:

Resolution:

00020001 Corresponds to register 3050 and 3051
3050 = 0001
3051 = 0002

From the register map this maps out to:
3050 = 0000 0000 0000 0001 = Error
3051 = 0000 0000 0000 0010 = tbd Option Slot A module failure

Looking at the code, it appears the issue is related to IO. more information about registers 3050 and 3051 please refer to the PM800's register map. See the Modbus maps here Series 800 Power Meter (PM800) Modbus Register Lists | Schneider Electric USA
