TIme Delay for Reconnections to Servers
Source Host reconnection delay
This parameter sets the time delay for attempting to reconnect to source PI Data Archive after a disruption. The number is entered in seconds and converted to milliseconds before being saved in the batch file. This number must be between 1 second and 8 hours. (command line parameter /DELAYS= x, which has a default value of 0 seconds)
Receiving Host reconnection delay
This parameter set the time delay for attempting to reconnect to receiving PI Data Archive after a disruption. The number is entered in seconds and converted to milliseconds before being saved in the batch file. This number must be between 1 second and 8 hours. (command line parameter /DELAYR= x, which has a default value of 0 seconds)
Suppress I/O Timeout
Suppress writing I/O Timeout to tags upon reestablishment of a lost connection to the source PI Server
In case you have inadvertently set Location3 to write the I/O Timeout digital state for tags used by the PI to PI interface, use this parameter to suppress writing the I/O Timeout state upon reestablishment of a lost connection to the source PI Data Archive.
Note: If this parameter is not set, the I/O Timeout state written at reconnection will prevent history from being recovered for the period of the disconnection. (command line parameter /TS)
Future Data
Future Data Collection Period
When using future tags, use this parameter to set how far into the future the interface will search for data each scan. If this parameter is not set, the interface will only scan for data between the time of the last scan and the current time. (command line parameter /FD, which has a default value of 0 seconds)
