7.1 Unstable analog output value

7.2 Analog output value does not change

If the analog output value is unstable, check the following:
 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.
If the analog output value remains unchanged, check the following:
 Check that the unit is in RUN mode.
 Check that I/O allocations are correct.
 Check the connections of the terminal block.
 Check that the impedance of the input device is 500Ω or below if a cur-
rent output range has been set.
 Check that the output is not short-circuited.
 Check that the digital input value is within the range.
 Check the configuration settings.
