Details about T_DIS_OUT_STD Type IODDT Explicit Object Exchange

At a Glance

This section presents T_DIS_OUT_STD type IODDT Explicit Object Exchange that applies to discrete output modules. It regroups word type objects, which bits have a particular meaning. These objects are explained in detail below.

Example of declaring a variable:

IODDT_VAR1 of type T_DIS_OUT_STD.

NOTE: Generally, bit meaning is provided for state 1 of that bit. In specific cases each bit state is explained.

NOTE: Not all bits are used.

Explicit exchange execution indicators: EXCH_STS

The following table shows exchange control bit meanings for channel EXCH_STS (%MWr.m.c.0).

Standard symbol	Type	Access	Meaning	Number
STS_IN_PROGR	BOOL	R	Status words reading for the channel in progress.	%MWr.m.c.0.0
CMD_IN_PROGR	BOOL	R	Command parameters exchange in progress.	%MWr.m.c.0.1

Explicit exchange report: EXCH_RPT

The table below shows EXCH_RPT (%MWr.m.c.1) report bit meanings.

Standard symbol	Type	Access	Meaning	Number
STS_ERR	BOOL	R	Channel status word reading error (1 = failure).	%MWr.m.c.1.0
CMD_ERR	BOOL	R	Error during command parameter exchange (1 = failure).	%MWr.m.c.1.1

Standard channel faults: CH_FLT

The table below shows the CH_FLT (%MWr.m.c.2) status word bit meanings. The reading is performed by a READ_STS (IODDT_VAR1).

Standard symbol	Type	Access	Meaning	Number
TRIP	BOOL	R	External error: Tripped.	%MWr.m.c.2.0
FUSE	BOOL	R	External error: Fuse.	%MWr.m.c.2.1
BLK	BOOL	R	Terminal block error.	%MWr.m.c.2.2
EXT_PS_FLT	BOOL	R	External supply fault.	%MWr.m.c.2.3
INTERNAL_FLT	BOOL	R	Internal error: H.S. module	%MWr.m.c.2.4
CONF_FLT	BOOL	R	Hardware or software configuration error.	%MWr.m.c.2.5
COM_FLT	BOOL	R	Communicating with automaton fault.	%MWr.m.c.2.6
SHORT_CIRCUIT	BOOL	R	External error: Short-circuit on a channel.	%MWr.m.c.2.8
LINE_FLT	BOOL	R	External error: Line fault.	%MWr.m.c.2.9

Status word: CH_CMD

The table below shows the CH_CMD (%MWr.m.c.3) status word bit meanings. The command is executed by a WRITE_CMD (IODDT_VAR1).

Standard symbol	Type	Access	Meaning	Number
REAC_OUT	BOOL	R/W	Reactivation of tripped outputs (protected outputs).	%MWr.m.c.3.0
PS_CTRL_DIS	BOOL	R/W	Inhibit control of external supply.	%MWr.m.c.3.1
PS_CTRL_EN	BOOL	R/W	Validation of the external supply control.	%MWr.m.c.3.2

NOTE: This object is specific to output modules with reactivation.
