The valid range is 0…65535. Default value is 0.
Number of Class1 Events
If the MicroLogix 1400 is configured not to initiate Unsolicited Response, this
parameter used to limit the maximum number of events which is generated and
logged into the event buffer for Class 1 events. In this case, value 0 will disable to
generate the event.
If the MicroLogix 1400 is configured to generate Unsolicited Response, and the
number of queued Class 1 events is reached to this value, Unsolicited Response is
initiated.
The valid range is 0 to 6013. Default value is 10.
Hold Time after Class1 Events (x1 s)
This parameter is only for Unsolicited Response. The MicroLogix 1400 holds the
events during Hold Time after Class1 Events (x1 s) before initiating an
Unsolicited Response.
The valid range is 0…65535. Default value is 5.
The value of 0 indicates that responses are not delayed due to this parameter.
Note that parameters Number of Class1 Events and Hold Time after Class1
Events (x1 s) are used together so that if either one of the criteria are met, an
Unsolicited Response is transmitted.
Number of Class2 Events
If the MicroLogix 1400 is configured not to initiate Unsolicited Response, this
parameter used to limit the maximum number of events which is generated and
logged into the event buffer for Class 2 events. In this case, value 0 will disable to
generate the event.
If the MicroLogix 1400 is configured to generate Unsolicited Response, and the
number of queued Class 2 events is reached to this value, Unsolicited Response is
initiated.
The valid range is 0 to 6013. Default value is 10.
Hold Time after Class2 Events (x1 s)
This parameter is only for Unsolicited Response. The MicroLogix 1400 holds the
events during Hold Time after Class2 Events (x1 s) before initiating an
Unsolicited Response.
The valid range is 0 to 65535. Default value is 5.
