Free replacement for applications like ModScan, Modbus Poll etc. Modbus allows for communication between many devices connected to the same network.

Modbus protocol exist for serial port (RTU) and for Ethernet (TCP).

).This software utility is written for testing Modbus slave devices. function code, address to be read out, data value. The exception messages there should be extended with information about the ModbusRequest m_Request (e.g. Further are both exceptions most likely coming from ModbusTCPTransaction. IMHO one should raise the log level of the errors fetched in the ModbusSlave.java especially the two possible log outputs concerning this error. It is hard to debug because of so little exception information. Please check that in the devices datasheet and also please post an output of mbtget with *additional option* -d, asking *that very device* on which you are trying with openHAB.

ModbusSlave error getting responce from slaveįor me that seems like an exception coming from the slave, code "1" means "Illegal Function", I guess (because I dont know what data where actually sent to the device) that the target doesn't support Read Input Registers (function code four). 20:41:21.057 - Modbus Polling Service has been started 20:41:16.267 - Started Classic UI at /openhab.app 20:41:11.308 - Loading model 'cogeneration.sitemap' 20:41:01.498 - Service Discovery initialization completed. 20:41:01.123 - mDNS service has been started Java.io.FileNotFoundException: webapps/static/version (Permission non accordée)Īt .CoreActivator.createVersionFile(CoreActivator.java:107) Īt .CoreActivator.start(CoreActivator.java:59)

I can read this data from other clients like mbtget are giving me the answers : I want to read function 4 data from a modbus tcp slave
