The @SL central block allows the initialization and monitoring of
communications with an SLB module.
An SLB module is a system hardware component, which can be an ITSL-
, an EXM 448-1 module or an optional SLB (
S IMO L INK B oard) of the
ITSL module.
The @SL central block may only be configured in a cyclic task and once
per SIMOLINK ring.
The following parameters must be set for an SLB module:
•
Hardware address SLB (TAD)
•
Operating mode (MOD)
•
Node address (ASL), only relevant when operating mode 0 is selected
•
Send power (POW) for the SLB module
1. The @SL central block executes the following steps while the system
is being initialized:
−
Checks the validity of the value ranges at the input connections
−
Checks whether additional @SL central blocks have been
configured at the same hardware address (input TAD)
−
Initializes the SLB module corresponding to the data at the
initialization connections
