Parameter Description

Description of the block parameter

Parameters	Data type	Significance
`SET`	`XMIT_SET`	Data structure for the XMIT configuration
`MSG_OUT` (1)	`ANY`	Buffer for outgoing messages (in 4x range)
`PORT`	`BYTE`	Port (0 or 1)
`START`	`BOOL`	1: Starts XMIT operation
`ABORT`	`BOOL`	1: Aborts current XMIT operation
`MSG_IN` (1)	`ANY`	Buffer for incoming messages (in 4x range)
`CFG`	`XMIT_SET`	Data structure with all components of the XMIT configuration, including the automatically set and not used variables. Only for display and must be in 4x range
`OP_ACT`	`BOOL`	1: XMIT operation in progress
`NO_SUC`	`BOOL`	1: Operation terminated UNsuccessfully
`OP_SUC`	`BOOL`	1: Operation terminated successfully
`EXT` (2)	`INT`	Displays an error code generated by XMIT
(1) No check for mapping in quad register. It may be an unlocated data.
(2) Used for another purpose with hot standby Momentum
