SYNPOL®D offers via the RS422/RS485 communication port the Modbus protocol in accordance with „Gould Modbus protocol“ Reference guide PI-MBUS-300 Rev. B.
The protocol controls the query and response cycle which takes place between master and slave devices.
The protocol provides for one master and up to 247 slaves on a common line. SYNPOL®D operates as slave within this network and covers the function 1,2,3,6 & 8 of the Modbus protocol.
