SINTESI SMART Modbus ROTARY ACTUATOR FOR BALL VALVES WITH PROPORTIONAL CONTROL FUNCTIONS Modbus communication The communication protocol used is compatible with MODBUS-RTU. The protocol handles up to 255 different tools. The data is transmitted as a packet (message) and is controlled by a word (CRC). There are no limits to the number of possible attempts the Master can make. The communication complies with the EIA-RS485 standard in half duplex mode. In this case, only one instrument at a time can keep the line busy, since only two wires are used; this means that there must be a master polling...
