A maximum of 8 setpoints can be transferred to a maximum of 8 slaves
using the SLSV send block. Only one setpoint can be sent to each slave,
and for all of the slaves, only the same channel number can be
addressed.
The SLSV and SLSV_R function blocks are functionally identical. The
only difference is the data type of the setpoint connections XS0 to XS7:
SLSV:
SLSV_R:
1. The SLSV send block executes the following steps while the system is
being initialized:
− Checks the task assignment
− Initializes the task-list of the SLB module corresponding to the data
configured at the inputs
2. In the normal system mode ("RUN" mode), the SLSV send block
executes the following:
− Calculates the setpoints
− Checks that the inputs are within the permissible value ranges
− Enters the setpoints to be sent into the write buffer of the SLB
module
