The standard settings for the input and output devices are:
Station number (NET-ID) and baud rate can be specified via
station 1.
Station message types
The CL-NET network recognises various message types.
They are:
• Output data of station 1 (Q., S.) which is sent to stations
without programs.
• Send and receive network outputs and inputs between
stations with the program (*SN, *RN).
• Send and receive data between stations with the program
(PT and GT function blocks).
• Transfers of inputs, outputs, station status (I, R, Q, S).
• Load programs to and from every station.
The CL-NET network is based on a CAN (Controller Area
Network) system. Each message type has its own ID. The
message priority is determined via the respective ID. This is
important in transmission borderline cases to ensure that all
messages reach their destination.
