2 setpoints can be sent to each slave using the SLSV2 send block. In this
case, the block can handle a maximum of 8 slaves. The first setpoint is
transferred to all of the 8 slaves.
This functionality can be used to implement a virtual shaft, especially if
the time and the position/angular setpoint must be transferred to the
slaves.
The SLSV2 and SLSV2R function blocks are functionally identical. The
only difference is the data type of the setpoint connections XO0 to XO7:
SLSV2:
SLSV2R:
1. The SLSV2 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 SLSV2 send block
executes the following steps:
− 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
