Number of Occupied Stations (SW3)
Occupied Stations setting determines the number of 32 bit station buffer memory locations that will
be allocated for this station in the Master buffer memory. This sets the number of total I/O available
for the station. Each memory bit has a designated input AND output buffer. So a setting of (1) 32
station actually allocates 32 input & 32 output locations for a total of 64 total points. This switch must
be set before power is on, and cannot be changed during operation.
NOTE: See FEC Electrical Controls drawings for actual setting required as this may vary per
application.
