Hi Guys,
Hope someone can shed some light for this newby
I'm currently configuring an AB ML1400 to talk to a IME Power Meter over Modbus RTU RS485. This is my first time using the ML1400 with Modbus and it seems reasonably straight forward.
I'm looking to read input registers so have setup the commands as follows to test the data retrieval before going further. I'm looking to read the Phase 1 Voltage in address 0x301 all the way through to apparent power 0x321
Command: 04 Read input registers
Data Table Address N7:81
Size In Elements: 26
MSg Timeout:100
MB Data Address: 1
Slave Node: 1
modbus address: 30001
My issue is the reply I'm getting is Error Code (hex) 37 - Message timed out in local processor
See below screenshot of my setup.

Has anyone got any ideas why the meter is not reading my request properly?
Regards
David
