C200H Interface Unit Switch Settings
Set all the DIP switches (SW1, SW2) of the C200H interface unit to “OFF” (re-
served for system use) and set the unit number to 0 with the rotary switch (SW3).
It is necessary to set a machine number for NT600S since it operates as a high-
level function I/O unit of C200H. Make sure that the machine number to be allo-
cated is unique.
Switch cover
The DIP switches are located under the switch cover
on the front of the interface unit.
SW1 SW2 SW3
When using C200H/HS, or C200HX/HG/HE, the words corresponding to the
channel numbers indicated below are occupied for each unit number set. Howev-
er, since the NT600S uses the allocated bits and words for processing, it does not
use these words.
These words are used as internal auxiliary relays.
