Details concerning T_CSY_CMD-type IODDT explicit exchange objects

At a Glance

This part introduces explicit exchange objects of the T_CSY_CMD IODDT which apply to the TSX CSY 84 module. It groups word-type objects whose bits have a particular meaning. These objects are presented in detail below.

Example of declaration of a variable: IODDT_VAR1 of the type T_CSY_CMD

Notes

The meaning of bits is generally given for status 1 of this bit. In specific cases, each bit status is explained.
All bits are not used.

Indicators of explicit exchange execution: EXCH_STS

The table below explains the meanings of the exchange control bits for the EXCH_STS channel (%MWr.m.c.0).

Standard symbol	Type	Access	Meaning	Address
CMD_IN_PROGR	BOOL	R	Command parameters exchange in progress	%MWr.m.c.0.1

Explicit exchange report: EXCH_RPT

The following table explains the meaning of the EXCH_RPT report bits (%MWr.m.c.1).

Standard symbol	Type	Access	Meaning	Address
CMD_ERR	BOOL	R	Fault during exchange of command parameters	%MWr.m.c.1.1

WRITE_CMD interface words

The following table explains the meanings of the variables associated with the WRITE_CMD whose action was specified in the word ACTION_CMD. These variables are updated by a WRITE_CMD (IODDT_VAR1).

Standard symbol	Type	Access	Meaning	Address
ERROR_CMD	INT	RW	Error during WRITE_CMD	%MWr.m.c.19
RETURN_CMD_1	DINT	RW	Return 1 of the function	%MDr.m.c.20
RETURN_CMD_2	REAL	RW	Return 2 of the function	%MFr.m.c.22
RETURN_CMD_3	REAL	RW	Return 3 of the function	%MFr.m.c.24
ACTION_CMD	INT	RW	Action to be carried out	%MWr.m.c.26
PARAM_CMD_1	DINT	RW	Parameter 1	%MDr.m.c.27
PARAM_CMD_2	DINT	RW	Parameter 2	%MDr.m.c.29
PARAM_CMD_3	REAL	RW	Parameter 3	%MFr.m.c.31
PARAM_CMD_4	REAL	RW	Parameter 4	%MFr.m.c.33
