Details of the Explicit exchange objects of the IODDT of the T_COM_STS

At a Glance

This part presents the explicit exchange objects of the IODDT of the T_COM_STS_GEN type that applies to all the communication protocols except Fipio and Ethernet. This groups together word type objects, the bits of which have a particular meaning. These objects are presented in detail below

Example of declaration of a: IODDT_VAR1 variable of type T_COM_STS_GEN.

Notes

Generally the meaning of the bits is given for state 1 of each bit. In certain cases each state of the bit is explained.
Not all the bits are used.

Explicit exchange indicator: EXCH_STS

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

Standard symbol	Type	Access	Meaning	Address
STS_IN_PROGR	BOOL	R	Reading of the status words of the current channel.	%MWr.m.c.0.0
CMD_IN_PROGR	BOOL	R	Command parameters exchange in progress.	%MWr.m.c.0.1
ADJ_IN_PROGR	BOOL	R	Command parameters adjustment in progress.	%MWr.m.c.0.2

Explicit exchange report: EXCH_RPT

The table below presents the meanings of the report bits EXCH_RPT (%MWr.m.c.1).

Standard symbol	Type	Access	Meaning	Address
STS_ERR	BOOL	R	Channel status words reading error.	%MWr.m.c.1.0
CMD_ERR	BOOL	R	Fault during a command parameters exchange.	%MWr.m.c.1.1
ADJ_ERR	BOOL	R	Fault during an adjustment parameters exchange.	%MWr.m.c.1.2

Standard channels faults, CH_FLT

The table below presents the meanings of the status word bitsCH_FLT (%MWr.m.c.2). The reading is performed by a READ_STS(IODDT_VAR1).

Standard symbol	Type	Access	Meaning	Address
NO_DEVICE	BOOL	R	No device is working on the channel.	%MWr.m.c.2.0
1_DEVICE_FLT	BOOL	R	A device on the channel is faulty.	%MWr.m.c.2.1
BLK	BOOL	R	Terminal strip error (not connected).	%MWr.m.c.2.2
TO_ERR	BOOL	R	Timeout error (faulty wiring).	%MWr.m.c.2.3
INTERNAL_FLT	BOOL	R	Internal fault or channel self-test.	%MWr.m.c.2.4
CONF_FLT	BOOL	R	Different hardware and software configurations.	%MWr.m.c.2.5
COM_FLT	BOOL	R	Problem communicating with the PLC.	%MWr.m.c.2.6
APPLI_FLT	BOOL	R	Application fault (adjustment or configuration fault).	%MWr.m.c.2.7
