Alarm Environment Setting Setting Chattering Guard Time of Alarm Input for VN-E4 Format /api/param?peripheral.input_pin.pin(Number).chatter=data Example When setting the chattering guard time for alarm input 1 /api/param?peripheral.input_pin.pin(1).chatter=150 Example of response peripheral.input_pin.pin(1).chatter&200 OK Interpretation Change the time setting to prevent chattering in the alarm input. Specify a number between 1 to 4 as VN-E4 has 4 alarm inputs. Unit of the response value is in msec. Allowed users admin, operator Acquiring Alarm Output Time Setting from VN-E4 Format /api/param?peripheral.output_pin.pin.duration Example of Response peripheral.output_pin.pin.duration=1000&200 OK Interpretation Acquire the current alarm output duration in millisecond. If alarm output is set in alarm action, this parameter can be acqurired by following API. /api/param?application.event(Number).action Allowed users admin, operator, user Setting Alarm Output Time for VN-E4 Format /api/param?peripheral.input_pin.pin.duration=data Example /api/param?peripheral.input_pin.pin.duration=50 Example of response peripheral.input_pin.pin.duration&200 OK Interpretation Change the alarm output duration in millisecond. Specify 0, or 50 to 5000. Following API is also available to set the parameter. /api/param?application.event(Number).action Allowed users admin, operator Acquiring Alarm Output Status from VN-E4 Format /api/param?peripheral.output_pin.pin.status Example of Response peripheral.output_pin.pin.status=make&200 OK Interpretation Acquire the current alarm output status. Either make or break will be returned.

5. API for Acquiring/Changing Parameters of VN-E4 _
5.5. Alarm Environment Setting
Setting Chattering Guard Time of Alarm Input for VN-E4
Format
/api/param?peripheral.input_pin.pin(Number).chatter=data
Example
When setting the chattering guard time for alarm input 1
/api/param?peripheral.input_pin.pin(1).chatter=150
Example of response
peripheral.input_pin.pin(1).chatter&200 OK
Interpretation
Change the time setting to prevent chattering in the alarm input. Specify a number between 1 to 4 as VN-E4
has 4 alarm inputs. Unit of the response value is in msec.
Allowed users
admin, operator
Acquiring Alarm Output Time Setting from VN-E4
Format
/api/param?peripheral.output_pin.pin.duration
Example of Response
peripheral.output_pin.pin.duration=1000&200 OK
Interpretation
Acquire the current alarm output duration in millisecond. If alarm output is set in alarm action, this parameter
can be acqurired by following API.
/api/param?application.event(Number).action
Allowed users
admin, operator, user
Setting Alarm Output Time for VN-E4
Format
/api/param?peripheral.input_pin.pin.duration=data
Example
/api/param?peripheral.input_pin.pin.duration=50
Example of response
peripheral.input_pin.pin.duration&200 OK
Interpretation
Change the alarm output duration in millisecond. Specify 0, or 50 to 5000. Following API is also available to
set the parameter.
/api/param?application.event(Number).action
Allowed users
admin, operator
Acquiring Alarm Output Status from VN-E4
Format
/api/param?peripheral.output_pin.pin.status
Example of Response
peripheral.output_pin.pin.status=make&200 OK
Interpretation
Acquire the current alarm output status. Either make or break will be returned.

Changing Alarm Output of VN-E4
Format
/api/param?peripheral.output_pin.pin.status=data
Example
/api/param?peripheral.output_pin.pin.status=break
Example of Response
peripheral.output_pin.pin.status&200 OK
Interpretation
