Programming Example
The Sub I/O Scanner is in slot 1, module group 7 of the local I/O rack. The
Sub I/O Scanner is connected to three RediPANEL 16 button modules, each
configured for 1/4 rack.
•
The Block Transfer Length is 14 (8 words for utility functions and 2
words for each of the 3 RediPANELS configured for 1/4 rack.
•
Data File address for the block transfer read starts at N11:0. This means
that addresses for RediPANEL buttons start at N11:8.
The Data File for the block transfer write starts at N12:0. This means
addresses for the RediPANEL lamps start with N12:8.
