4.4.4.2 SIMOLINK function blocks
The configuring engineer can use the following function blocks:
• @SL
• SLAV
• SLSV
• SLSV2
• SLSVAV
• SLD
• SLDIS
The central block @SL permits the initialization and monitoring of
communications in a SIMOLINK ring.
It may only be configured once for each SIMOLINK ring in a sampled
cyclic task (T4 or T5) which is, as a minimum, 4x longer than the send
and receive block.
If a transceiver no longer receives a telegram as a result of an
interruption, then it automatically sends a special telegram, which
evaluates the @SL function block. The address of the node is output at
NDM, which first signals the fault.
Additional information regarding the mode of operation and the
NOTE
connections (I/O) of the specified blocks are provided in the online help
of the CFC Editor and in the "Function block library" reference Manual".
