4.6.4.2 SIMOLINK function blocks
The configuring engineer can use the following function blocks:
@SL SIMOLINK central block
SLAV SIMOLINK receive block, one for each actual value
SLSV SIMOLINK send block, one for each setpoint
SLSV2 SIMOLINK send block, for two setpoints
SLSVAV SIMOLINK send and receive block for up to 8 setpoints
and actual values of the slave
SLD SIMOLINK delta evaluation
SLDIS SIMOLINK dispatcher
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.
NOTE
Additional information regarding the mode of operation and the
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".
