Internal control objects (explicit exchange) of the IODDT of type T_STEPPER

At a Glance

This part presents the internal status objects (explicit exchange) of the IODDT the T_STEPPER_STD type which applies to the TSX CFY11/21 modules. It groups the word type objects, the bits of which have a special significance. These objects are presented in detail below.

Notes

Generally, the significance of the bits is given for status 1 of the bit. In some cases each bit status is explained.
Not all the bits are used.

Management of the exchanges: EXCH_STS

The table below shows the meaning of channel exchange check bits EXCH_STS (%MWr.m.c.0).

Standard symbol	Type	Access	Meaning	Address
STS_IN_PROGR	BOOL	R	Exchange in progress of status parameters (STATUS)	%MWr.m.c.0.0
CMD_IN_PROGR	BOOL	R	Command parameters exchange in progress	%MWr.m.c.0.1
