What to Do If an Error Occurs

7.1 What to Do If an Error Occurs (Analog Input)

7.1.1 Failure in Reading Analog Input Data

• Check again that I/O allocations are correct.
• Check again the connections of the terminal block.
• Check again the configuration settings.

7.1.2 Unstable Analog Input Conversion Value

• Used a twisted pair shield wire and check that the wire is properly shielded.
• Check that the analog input wiring is not placed close to AC lines or high-tension lines or
bundled with the lines.
• Check that there are no power lines, high-tension lines, high-capacity relays, or noise-
generating equipment, such as inverters, close to the analog input unit.

7.1.3 No Proper Conversion Values Obtained with Current Input

• Check again the connections of the terminal block.
• Check again the connections of the output equipment.
