Both data and commands can be transferred between the Position Control
Unit (PCU) and Programmable Controller (PC) through the use of Intelligent
I/O Read and Write instructions executed by the PC.
The Intelligent I/O Read instruction READ(88) and Intelligent I/O Write in-
struction WRIT(87) control PCU-PC communication. The CPU must be able
to use these two instructions. Use of the NC222-E is thus possible with the
following PCs only.
•
C500 (with CPU model C500-CPU11-EV1 only)
•
C1000H (with any CPU)
•
C2000H (with any CPU)
Note The NC222-E must be mounted either to a CPU Rack or Expansion I/O Rack
to operate. Communications via READ(88) and WRIT(87) will not be possible
if it is mounted to a Slave Rack.
Two I/O words are allocated for the Position Control Unit for communication
with the PC.

Note 1. The input and output words allocated to the Position Control Unit must not
be used by any instruction other than WRIT(87) or READ(88).
Do not use MOV(21) or OUT with these words.
2. The mode of the PC has no affect on the operation of the NC222-E, i.e.,
the NC222-E will continue to operate regardless of the PC mode.
3. Commands and/or data can be sent to the NC222-E from either the PC
(i.e., the program) or the Teaching Box. If a transmission is attempted
from both at the same time, the transmission that arrives first will be given
priority.
