What to Do If an Error Occurs

7.1 What to Do If an Error Occurs

7.1.1 Unstable Analog Output Value

• Check if the shielded wire of the input device is grounded.
However, depending on the conditions of the external noise, it may be better not to ground the
shielding.
• Review the program again.

7.1.2 Unchanged Analog Output Value

• Check that the unit is in RUN mode.
• Check again that I/O allocations are correct.
• Check again the connections of the terminal block.
• Check that the impedance of the input device is 500 Ω or below if the current output range is set.
• Check that the output is not short-circuited.
• Check that the digital input value is within the range.
• Check the configuration settings.
