Technical data

☞
The firmware of the CP 5430 TF/CP 5431 FMS activates all the
specified SAPs for the services SDA, SDN and SRD (both for
the initiator and responder functions). The L2 address range
of the remote station is not restricted.
Once the "channels" have been assigned parameters with the link editor for
every L2 station with a CP 5430 TF/CP 5431 FMS that is intended to
communicate via the free layer 2 access, the required data transfer must be
coordinated in the control program.
