Detailed Description of Explicit Exchange Objects for the T_ANA_OUT_STD and T_ANA_OUT

At a Glance

This section presents the Explicit Exchange Objects for the T_ANA_OUT_STD and T_ANA_OUT_STDX IODDT, applicable to all analog output modules. This section regroups word-type objects whose bits have a specific meaning. These objects are described in detail below.

Sample Variable Declaration: T_ANA_OUT_STD named IODDT_VAR1.

Sample Variable Declaration: T_ANA_OUT_STDX named IODDT_VAR2.

NOTE: Generally speaking, the meaning of any bit is provided for State 1 of said bit. In some specific instances, we provide a meaning for each state of the bit.

Not all bits are utilized.

Implicit Exchange Execution Indicators: EXCH_STS

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

Standard symbol	Type	Access	Meaning	Address
STS_IN_PROGR	BOOL	R	Channel status words are in the process of being read.	%MWr.m.c.0.0
CMD_IN_PROGR	BOOL	R	The exchange of Command Parameters is in progress.	%MWr.m.c.0.1
ADJ_IN_PROGR	BOOL	R	The exchange of Adjustment Parameters is in progress.	%MWr.m.c.0.2

Explicit Exchange Report: EXCH_RPT

The following table explains the various meanings of EXCH_RPT (%MWr.m.c.1) reporting bits.

Standard symbol	Type	Access	Meaning	Address
STS_ERR	BOOL	R	Error while reading the channel status words.	%MWr.m.c.1.0

APPLI_FLT	BOOL	R	Application Error (configuration or adjustment error).	%MWr.m.c.2.7
NOT_READY	BOOL	R	Channel not ready.	%MWr.m.c.2.8

Channel Fallback value: FALLBACK

The following table explains the meaning of FALLBACK (%MWr.m.c.5) integer. Queries used are those associated with parameters (READ_PARAM, WRITE_PARAM, SAVE_PARAM, RESTORE_PARAM, for example: READ_PARAM(IODDT_VAR2)).

Standard symbol	Type	Access	Meaning	Address
FALLBACK	INT	R/W	Channel fallback value, this data is only available for T_ANA_OUT_STDX IODDT.	%MWr.m.c.5
