PLC Setup
Use the CX-Programmer to set the various PLC Setup including whether the I/O point is being used,
the input range, output range and averaging function usage. The I/O point usage, input range, output
range, and averaging function usage can be set independently for each I/O point.
• The input range can be set to -10 to 10 V, 0 to 10 V, 1 to 5 V, 0 to 5 V, 0 to 20 mA or 4 to 20 mA.
• The output range can be set to -10 to 10 V, 0 to 10 V, 1 to 5 V, 0 to 5 V, 0 to 20 mA or 4 to 20 mA.
• Once the range has been set, it cannot be changed as long as the CP1E CPU Unit's power is ON. To
change the input range or output range, change the setting in the PLC Setup, turn the CPU Unit OFF,
and then turn the CPU Unit ON again.
15-2
• Set whether each input or output will be used.
(Each I/O point is set independently.)
PLC Setup
• Set the I/O resolution.
(The same setting is used for all I/O points.)
• Set the analog input range:
0 to 5 V, 1 to 5 V, 0 to 10 V, -10 to 10 V, 0 to 20mA or
4 to 20mA
(Each input is set independently.)
• Set the analog output range:
0 to 5 V, 1 to 5 V, 0 to 10 V, -10 to 10 V, 0 to 20mA or
4 to 20mA
(Each output is set independently.)
• Wire the I/O devices.
Select correct wire method according to the voltage
or current input.
• Analog inputs: Read the conversion value.
• Analog outputs: Write the conversion value.
