Name
This is the terminal block for inputs such as the power supply input and 24
VDC inputs.
Input status is displayed. An indicator will be ON when the input is ON.
Used to connect to a personal computer for programming and monitoring
by the CX-Programmer for CP1E.
By turning an analog adjuster, it is possible to adjust the value of A642 or
A643 within a range of 0 to 255.
Refer to Section 17 Built-in Functions in the CP1E CPU Unit Software
User's Manual (Cat. No. W480).
The CPU Unit's operating status can be confirmed with this indicator.
Refer to CPU Unit Status Indicators (Page 3-3).
Loads such as lamps, contactors, and solenoid valves can be connected.
Power of 100 to 240 VAC can be supplied.
Protective ground (
Input devices such as switches and sensors can be connected.
This is the terminal block for outputs such as relay outputs and transistor
outputs.
A Battery can be installed by opening the cover. (The Battery is optional).
This indicator will flashing if the built-in RS-232C port is in communication
mode.
By connecting a PT, the controlled system can be monitored and data can
be collected.
