I have a digital panel meter like this (datasheet here: http://drop.io/tvsshq0 ).
The desire is to read the voltages, currents and network frequency from the multimeter. It has a rs485 interface and knows modbus_rtu. I connected it to a rs485/Ethernet converter and then to the LAN. I've tried different ways of connecting to the device and reading the data but no chance on this.
Can you direct me to some help, a simple freeware that i can test the connection is ok for start. The final goal is to be able to read the data via a script (python, perl, php whatever works more easily) and dump it into a database for further analysis and alert generation.
Best regards,
Mike
