Modbus RTU technology

Modbus RTU is an open serial protocol based on master/slave architecture. The protocol
interconnects field equipment such as sensors, actuators, and controllers and is widely used in
both process and manufacturing automation. The fieldbus environment is the base level group
of digital networks in the hierarchy of plant networks.
Features
The SITRANS F Modbus RTU communication complies with the Modbus Serial Line Protocol.
Among other things this implies a master / slave protocol at level 2 of the OSI model. A node
(the master) issues explicit commands to one of the slave nodes and processes responses.
Slave nodes will not transmit data without a request from the master node, and do not
communicate with other slaves.
Modbus is a mono master system, only one master can be connected at a time.
