Table 114: PROFIBUS_FSPMS_CMD_C2_INITIATE_IND – Indication Command of a Request to establish a DP-Master
Class 2 Connection
This service has to be used by the AP-Task in order to confirm a previously FSPMS-Task issued
DP-Master Class 2 initialization indication. The response is required and a must do when having
received
the
indication
command
declared
in
Table
114:
PROFIBUS_FSPMS_CMD_C2_INITIATE_IND – Indication Command of a Request to establish a
DP-Master Class 2 Connection. In order to address the correct AREP, the response command
service has to be used in conjunction with the received ulFSPMS2Id value of the confirmation packet
referenced in Table 75: PROFIBUS_FSPMS_CMD_INIT_MS2_CNF – Confirmation Command of
MS2 Initialization for a DP-Master Class 2 connection.
The response is generally distinguished into two types:
