1. value = event.getvalue()
2. mb = mbproxy.new()
3. mb:setcoils(0, value)
Example: event script which changes modbus slave register (address 5)
Must be mapped to a group address with scaling (0..100) value
1. value = event.getvalue()
2. mb = mbproxy.new()
3. mb:setregisters(5, value)
LM interconnection with PLC over Modbus TCP
sleep time = 0. It only supports binary objects as coils and 1-byte / 2-byte integer objects as
registers. Number of coils and registers is not limited, object mapping can be set by filling coils,
registers and regdt tables.
