TIMING PARAMETERS 

6

Under normal operation, the FieldServer will send a poll request to a Server device and that device will reply with a 
response.  The amount of time between successive poll requests is called the 

Scan_Interval.  

The time between 

receiving a response from a Server device and the next poll request is called the 

Poll_Delay

.   

If the FieldServer sends a poll request, and the Server device does not send a response, it is considered a timeout.  
The time the FieldServer waits before declaring a timeout can be adjusted by the T

imeout 

parameter.  If a timeout 

occurs, then the FieldServer will retry the poll request a few times (number of times tried is specified by the 

retries

 

parameter).    The  interval  between 

retries

  is  specified  by  the 

Retry_Interval

.    The  FieldServer  will  send  poll 

requests at the end of each 

Retry_Interval.  

Once the specified numbers of 

Retries

 have been sent, the FieldServer 

will  mark  the  Node  offline.    Once  a  Node  has  been  marked  offline,  it  will  wait  for  a  period  specified  by 

Recovery_Interval

 before sending another poll request. 

Once the communications have been re-established, the FieldServer will wait for a period called 

Probation_Delay

, 

before marking the Node as online.  

Note 1:

  The 

Ic_Timeout

 parameter monitors the time between characters in a response.  If the time exceeds the 

Ic_Timeout

, the response is discarded and is considered a Timeout. 

Note 2:

  All parameters in 

bold 

above are configurable.  See table below for where they are configured, and what 

the defaults will be if they are not configured.   

Parameter 

Default Value  Where Used 

Scan_Interval 

2 seconds 

Map Descriptor, Node, Connection 

Poll_Delay 

0.05 seconds 

Connection 

Timeout 

2 seconds 

Map Descriptor, Node, Connection 

Retry_Interval 

10 seconds 

Node 

Retries 

3 times 

Node 

Recovery_Interval  30 seconds 

Node 

Probation_Delay 

1 minute 

Node 

Ic_Timeout 

0.5 seconds 

Map Descriptor, Node, Connection 

 

Note 3:

 A non-response from the remote Server device causes a Timeout.  The driver does nothing until a response 

is  received  or  the  timeout  period  has  expired.    Thus  if  a  connection  has  two  Nodes  and  one  Node  is  producing 
Timeouts this will have the effect of slowing down communication for the other Node in the sense that the driver 
does  nothing  while  the  timeout  timer  is  counting  up  to  its  setpoint.    Once  there  is  a  timeout  on  one  Node,  the 
driver  will  not  retry  any  Map  Descriptors  on  that  Node  until  the  Retry_Interval  has  expired.    Thus  during  the 
Retry_Interval the other Node will get 100% of the service.
