6-5-13 Function Block: Enable Switch Monitoring
Diagram
Default Connections
General Description
This function can be used only in NE1A-series Controllers with unit version
1.0 or later.
The Enable Switch function block monitors the status of the enable-switch
device.
The Output Enable signal is ON when the input from the monitored enable-
switch device is active. The Output Enable signal is OFF when the input is not
active or an error is detected in the function block.
In addition, if the enable-switch device is the type that outputs a grip signal
and release signal, the device’s Grip Input and Release Input signal status
can be monitored. The received Grip Input and Release Input signals do not
affect the status of the Output Enable signal.
Set Parameters
The timer SV must be longer than the NE1A-series Controller’s cycle time.
Number of I/O Points Setting
The number of inputs can be increased on the In/Out Setting Tab Page in the
function block property dialog box.
Optional Output Setting
The following outputs can also be used in programming. To enable any of
these optional outputs, select the corresponding checkbox on the Out Point
Tab Page of the function block properties dialog box.
