Gateway

[Bang]

Hi, Im extracting data from a Power Meter through modbus. Scada is giving me Device error of GATEWAY PATH UNAVAILABLE. Ive tried extracting from the meter to a PLC, it was fine, read all the data. But for he actual application, I wont be needing the PLC . Thanks for the assistance in advance.

Does your gateway work over Modbus TCP ? Has a port for access, for example 502 ? Perhaps you are requesting an address that is not in the gateway variables

Hi,

“[0A] GATEWAY PATH UNAVAILABLE!” is returned by a device. So you successfully communicate with a gateway at least.
Use Modbus Parser to check your request: 00 CD 00 00 00 06 01 03 0B CB 00 22
May be you need to change Unit ID (the address field).

Also try to request 1 register instead of 34 for testing.
