PLCS
S5–150U/S and
S5–155U
in
150U
mode during interrupt
processing (see section 9.4,8),
When the track number
(DL
n+l)
is less than 16, channel 1 is selected, otherwise channel 2.
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.

Entry of the track number parameter

tion.
