Function Switches

Overview
The NSH5 has ten function switches, and the status of these switches can be
sent to hard-wired outputs or to internal memory or host (PLC) memory.
The status of function switches F1, F2, F6, and F7 is output externally by
hard-wired outputs via the Special Cable. The status of the six remaining
switches (F3, F4, F5, F8, F9, and F10) are output to internal memory or host
(PLC) memory.

Internal Memory or Host
(PLC) Memory Allocation
NSH5 function switches F3 to F5 and F8 to F10 can be allocated any bit
addresses in the internal memory or host (PLC) memory, and their ON/OFF
status can be monitored at the allocated address.
To specify the address in internal memory or host (PLC) memory that is to be
allocated to a function switch, first select
PT - System Setting
in CX-Designer
and then click the
NS Handy Terminal
Tab. In the
Key Status Monitor
Address
Field, click the appropriate
Set
Button, and specify the address that
is to be allocated.
