Note If the same unit number that is used for another Special I/O Unit is set, a Unit
Number Duplication Error (fatal error) will occur in the CPU Unit (“UNIT No. DPL
ERROR” displayed at Programming Console), and the PC will not operate.
A40113 in the CPU Unit will turn ON.
Turn ON this switch to enable Programming Device servicing at the peripheral
port and turn it OFF to disable it. Operational errors related to the connection of a
Programming Device (such as changes in the operating mode) can be pre-
vented by turning OFF this switch.

Set to ON:
TOOL
ON OFF
Connection enabled
(The switch must be turned ON to use a
Programming Device.)
Set to OFF:
TOOL ON OFF
Connection disabled
(Turn OFF the switch to prevent
operational errors.)
Note 1. If the switch is turned OFF, Programming Device servicing is not performed
and so the scan time is shorter.
2. This switch can also be used as a restart switch for connection with the Pro-
gramming Device.
The peripheral port is used for connecting to a Programming Device (i.e., a Sup-
port Software installed on a computer or a Programming Console).
Note The Unit automatically recognizes the serial communications mode (i.e., Pro-
gramming Console bus, peripheral bus).
The I/O connector is for contact I/O. Make a cable for this connector with the
24-pin connector provided with the Unit. (For details, refer to 3-3 Wiring.)
The special I/O connector is for special I/O: Pulse inputs and pulse outputs for
the CS1W-HCP22, and pulse inputs and analog outputs for the CS1W-HCA22.
Either make a cable for this connector with the 40-pin connector provided with
the Unit, or using a special OMRON cable, connect to an OMRON Connector
Terminal Conversion Unit. (For details, refer to 3-3 Wiring.)
