6-5-10 Function Block: External Device Monitoring
Diagram
Default Connections
General Description
The External Device Monitoring function block evaluates the input signal and
the status of an external device and outputs safety outputs to an external
device.
If the input signal turns ON, the Output 1 and Output 2 signals will turn ON.
When this occurs, the status of the feedback signal must change within the
specified time. If the input signal turns OFF, the Output 1 and Output 2 signals
will turn OFF. When this
occurs, the status of the feedback signal must change within the specified
time.
If the status of the feedback signal does not change within the specified time,
an EDM error will occur, the Output 1 and Output 2 signals will turn OFF, and
the EDM Error signal will turn ON.
Set Parameters
The EDM Feedback Maximum Time Delay must be equal to or greater than
the cycle time of the NE1A-series Controller.
The network response time must be taken into consideration when inputting
the feedback signal from a remote device.
Optional Output Settings
The following outputs can also be used in programming. To enable either of
these optional outputs, select the checkbox on the Out Point Tab Page of the
function block properties dialog box.
EDM error
Output 2
Fault Present Output Setting
Fault Present output can also be used in programming.
To enable this output, select the Fault Present checkbox on the Out Point Tab
Page of the function block properties dialog box.
