A maximum of
•
8 setpoints and
•
8 actual values
can be transfered to and from one slave. The number of addressed
channels for the setpoints and the actual values is configured at the
inputs.
1. The SLSVAV send and receive 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 SLSVAV send and
receive block executes the following:
•
Checks that the inputs are within the permissible value range
•
Enters the setpoints to be sent into the write buffer of the SLB
module
•
Reads-out the actual values to be received from the receive
buffer of the SLB module
