Modbus Settings

[Pu2pl3]

Hi, I’m messing around with a Siemens Logo modbus Connection but cannot find the right settings. Is homebridge working as a modbus master or slave here? I tried both and get different errors. Can you pls help me out or is it so obvious? Thanks a lot.

Best regards Seb

Hi,

HB is the master then your plc is the slave

Plugins works easily with my old twido and with new M251

Hi eliziox, thank you for your immediate response. i set up the siemens logo plc as the slave and a blank modbus configuration:

{ "platform": "Modbus", "ip": "192.168.188.222", "port": 502, "pollFrequency": 10000, "accessories": [] }

the following error is reported in status of the hb (iterative reconnects)

[5/16/2024, 8:07:35 PM] [Modbus] true [5/16/2024, 8:07:35 PM] [Modbus] Connection lost [5/16/2024, 8:07:40 PM] [Modbus] Reconnecting to 192.168.188.222 [5/16/2024, 8:07:40 PM] [Modbus] Socket connected [5/16/2024, 8:07:40 PM] [Modbus] Error: read ECONNRESET at TCP.onStreamRead (node:internal/stream_base_commons:217:20) { errno: -104, code: 'ECONNRESET', syscall: 'read'

when configurating e.g. a switch for coil 1 the error is the same.

somebody any ideas on this?

thank you in advance
