Note Word (n+1) can be used for either the set data or the analog output conversion
value.
• Connect the Analog I/O Unit.
• Wire to analog I/O devices.
• Analog inputs: 0 to 5 VDC, 1 to 5 VDC, 0 to 10 VDC, –10 to
10 VDC, 0 to 20 mA, or 4 to 20 mA
• Analog outputs: 1 to 5 VDC, 0 to 10 VDC, –10 to 10 VDC, 0 to
20 mA, or 4 to 20 mA
• Set analog inputs as voltage or current inputs and set the
averaging function.
• Write set data to output words.
• Writes the set data.
• Reads the converted
values.
Writes the conversion
values.
