The user receives a "Negative Acknowledge" message when attempting to read registers through the EGX100 Read Device Registers webpage. This occurs when reading registers from devices connected that use PowerLogic protocol. These devices include Series 100, 200, 2000 Circuit Monitors (CM2000, CM100, CM200), Series 600 Power Meters (PM600), Digital Relays (DR), and PowerLogic Interfaces (PIF3 and PIF85).
This is a list of possible causes but are not limited:
- attempting to read a register which does not exist in a particular device
- incorrectly configured dipswitch biasing on the EGX100 RS485 port
Check to see that the correct register is being read and that the dipswitches are configured according to the diagram above.
