Programming Device
Connection Switch
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
prevented by turning OFF this switch.
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
Programming Device.
Peripheral Port
The peripheral port is used for connecting to a Programming Device (i.e., a
Support 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).
I/O Connector
(All Units)
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
.)
Special I/O Connector
(CS1W-HCP22-V1/HCA22-
V1/HCA12-V1 Only)
The special I/O connector is for special I/O: Pulse inputs and pulse outputs for
the CS1W-HCP22-V1, pulse inputs and analog outputs for the CS1W-HCA22-
V1, and pulse inputs, analog input and analog outputs for the CS1W-HCA12-
V1. 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 Con-
nector Terminal Conversion Unit. (For details, refer to
3-3 Wiring
.)
