Description
This class is needed to initialize the cyclical exchange of data between
master and slave.
A slave that implements the class SCP_VarCFG provides the following functions:
– Accesses via the service channel are completely supported
– Cyclical transmission of "Device Control" and "Device Status"
– The slave defines which data can be transmitted cyclically and how
many connections are possible. The slave provides the master with
these data to enable the master to initialize all connections correctly.
A slave that implements the class SCP_WDCon provides a watchdog
function that enables connections to be monitored and, in the event of
connection terminations, to initiate corresponding fault responses.
A slave that implements class SCP_Diag provides information that helps to
run bus diagnostics.
A slave that implements class SCP_NRTPC enables the UCC (Universal
Communication Channel) to be used for the transmission of
non-Sercos-Ethernet telegrams.
A slave that implements the class SCP_Cyc provides all of the functions
needed to transmit and to receive cyclical data (produce and consume).
