Details of T_ANA_IN_STD-Type IODDT Explicit Exchange Objects

At a Glance

This section presents the explicit exchange objects for the T_ANA_IN_STD-type IODDT applicable to all Analog input modules. It includes the word type objects whose bits have a specific meaning. These objects are described in detail below.

Example of declaration of a variable: IODDT_VAR1 of the T_ANA_IN_STD type.

Observations

In general, the meaning of the bits is given for bit status 1. In specific cases an explanation is given for each status of the bit.
Not all bits are used.

Execution Indicators of an Explicit Exchange: EXCH_STS

The table below presents the meanings of the exchange control bits of the channel EXCH_STS (%MW\2.e\0.m.c.0).

Standard symbol	Type	Access	Meaning	Address

CMD_IN_PROGR	BOOL	R	Current command parameters exchange in progress.	%MW\2.e\0.m.c.0.1
ADJ_IN_PROGR	BOOL	R	Adjustment parameters exchange in progress.	%MW\2.e\0.m.c.0.2

Explicit Exchange Report: EXCH_RPT

The table below presents the meaning of the exchange report bits EXCH_RPT (%MW\2.e\0.m.c.1).

Standard symbol	Type	Access	Meaning	Address
STS_ERR	BOOL	R	Reading error for channel status words.	%MW\2.e\0.m.c.1.0
CMD_ERR	BOOL	R	Error during a command parameter exchange (1 = failure).	%MW\2.e\0.m.c.1.1
