*) This parameter is used for PLCS S5–150U/S and S5–155U in 150U mode during interrupt
processing (see section 9.4.8).
The track number (DL n+l) can be disregarded for the IS, IV, RV, MB and PR functions.
The data block number of the user data block
(DR n+l) must be the same data block number
used also during startup in connection with function block FB 156.
See the description of function block FB 157 (section 9.3.7) for more details on handling the “inhib-
it interrupt” and “inhibit interrupt for supply” functions.
