This function block initializes cyclic transmission of a ParID to a transmit channel on a drive (readable for all POWERLINK stations). The channel number can be explicitly specified. A ParID value transmitted this way can be used as follows:
•Using MC_BR_InitReceiveParID to read from another drive
•Using MC_BR_ReceiveParIDOnPLC to read from the PLC
•Reading from an axis that is not controlled by PLCopen function blocks
Requirements for use
Function block name for SG3/SGC target systems MC_078BR_InitSendParID
PLCopen axis states in which the function block is permitted to be enabled
All PLCopen axis states, no effect on the PLCopen axis state
