Switch
<Operation specifications>
FALSE→TRUE:
Enables the scan list with fixed alloca-
tions.

abled.
• OUT area:
CIO 3200 to CIO 3263
(1 word/1 node address (fixed))
• IN area:
CIO 3300 to CIO 3363
(1 word/1 node address (fixed))
FALSE:

Clears and disables the scan list.
This switch clears the scan list and oper-
ates the Unit using fixed allocations with
the scan list disabled regardless of
whether operating using fixed allocations,
user-set allocations with device variables
for CJ-series Unit, or user-set allocations
by CX-Integrator. The fixed allocations
area used the last time the scan list was
disabled will be used.
FALSE:
