Memory Allocation Section 4-1
4-1 Memory Allocation
Memory Allocation According to the setting of the Unit number switch on the front of the C200H-
CP114 Cam Positioner Unit, 10 words are allocated for each Unit number in
the Special I/O Unit area between IR 100 to IR 199, which is used as the I/O
refresh data area. The IR area used by the C200H-CP114 Cam Positioner
Unit is refreshed on each C200H
PC I/O refresh cycle.
Note A Duplicate I/O Unit error occurs if the set Unit number corresponds to the
number of an existing Special I/O Unit.
