simple modbus tcp/rtu poller

polls modbus via tcp and rtu (serial)

return value can be piped to zabbix sender (xargs)

honours little endian / big endian coding of modbus values

Example of polling a SolarLog device via TCP about the current dc voltage and send the value to zabbix

modbus2zabbix -t -A 10.90.1.2 -i 1 -l 1 -R 3507 | xargs zabbix_sender -z 10.70.3.5 -p 10051 -s SolarLog -k solarlog.udc -o

Example of polling a Siemens power meter via RTU about the yield with swapped words

modbus2zabbix -r -A /dev/ttyUSB1 -i 1 -l 2 -R 6697 -S
