PID Operation Operating Instructions
4. Remote Operation (REM/AUT Mode)
Remote operation enables you to set the target value from a remote location
in one of the following two ways:
∑
Remote analog input operation
Target values are set by using an externally connected analog input device.
∑
Remote area switching operation
Area selection is done by using a set of external contacts.
Users must specify which feature is to be included in the controller when
their order is placed. Only one of the above (analog or area switching) can
be included.
With either of these features, you can operate the controller from a remote
site just as if you are standing in front of the operation panel.
4.1 Remote Analog Setting Operation
∑
The following setups must be done before starting the remote analog
setting operation.
1. Select the mode of analog input, current or voltage, by setting the
analog input selection jumper by referring to page 7.
Warning:
Improper setting of this jumper may damage the controller.
2. Setup all 6 items of parameter PG05/AiGr (analog setting input)
by referring to page 75.
Warning:
Improper setting of the parameter PG05/AiGr may produce
unexpected controller output.
3. Connect the analog input device by referring to the following
figure and tables.
