Exchange management: Exchanges in progress module
Presentation
Description
These word-type objects provide information on the module or channel i exchanges in progress.
They are updated automatically by the system.
The table below explains the meanings of the different bits in the word
%[email protected]
.
Address (1) Meaning for Xj = 1
%[email protected]:X0 Exchange of status words in progress on at least one channel of the module.
%[email protected]:X1 Exchange of command words in progress on at least one channel of the module.
Key:
(1) @module = module address.
z xy for in-rack modules, z \p2c\m for remote modules.
Description The table below explains the meanings of the different bits in the word
%[email protected]
.
Address (1)
%[email protected]:X0

Language words and bits
Example The example below shows one possible way in which this type of word can be used
(* Update request for channel 0 status words*)
(* for the module located at slot 3 of rack 0 *)
(* if no exchange in progress on this channel *)
IF NOT %MW3.0:X0 THEN READ_STS %CH3.0;
END_IF;
Note: If the explicit exchange does not last as long as the PLC task cycle time, the
%[email protected]:X0 bit never changes to 1.

(* Status error detected on module located at *)
(*slot 3 of rack 0 *)

Language words and bits
Explicit exchange objects: General
Presentation Explicit exchange objects carry information (e.g. terminal block fault, module missing etc.) and additional commands for advanced programming of specific application functions.
Note: The configuration constants %KW@ module.i.r (@ module = module address), which are not documented in this manual, are accessible in read only mode and correspond to the configuration parameters entered using the
Configuration editor.
Explicit exchanges objects are exchanged at the request of the user program using the following instructions: z READ_STS (read status words), z z z z z
WRITE_CMD (write command words),
WRITE_PARAM (write adjustment parameters),
READ_PARAM (read adjustment parameters),
SAVE_PARAM (save adjustment parameters),
RESTORE_PARAM (restore adjustment parameters).
