Basemapi Interface Page

Since the startup file of the PI Bailey SemAPI Interface is maintained automatically by the PI ICU, use the basemapi page to configure the startup parameters and do not make changes in the file manually. The following is the description of interface configuration parameters used in the PI ICU Control and corresponding manual parameters.

General Tab

Basemapi

Behavior

Enable exception screening

This option controls the exception screening behavior of the ICI module. With exception screening option enabled, the INFI90 sends only deviation exceptions, no maximum time exceptions. Though this feature will significantly reduce the communications traffic, it can prevent the PI system from reconstructing the data between two exception reports accurately.
For example: if a value changes slowly, then Bailey would not send the change until the total change exceeded the deviation limit. Therefore, one cannot distinguish a step change from a linear change. Hence, this option is set to 0 by default. The EF option is primarily used for system with mostly digital or discrete data. The command line equivalent is /ef.

Enable outputs

Enable outputs from PI to Bailey. The command line equivalent is /of.

Connection to an HNCC

This option specified that the interface is connecting to an HNCC as opposed to an ICI03.

Communication timeout

This option specifies the ICI module watch dog timer. If the interface stops communicating with the ICI module for a period longer than the specified watch dog timer, the ICI module will go off-line, setting all the output points (PI to Bailey) bad quality. For systems using PI values in the Bailey control loops, the watch dog timer will prevent old value from being used in the control loop. Also, do not set the watchdog timer to 0 if the interface is set up as fail over primary interface. Otherwise, the secondary interface will not pick up data collection when the primary interface stops communicating with the ICI module. See the Failover Operation section for details. The command line equivalent is /to=x.

Bailey logical ICI number

Bailey logical ICI number, set to interface ID number if not defined. The command line equivalent is /ici=x.

Time sync

This option controls the time synchronization behavior between Bailey and PI systems. Note that the interface cannot change the PI system time when the interface is running on Windows. Also, if the interface is linked to a Data Acquisition version of semAPI, the interface cannot set the time on the Bailey System. The time master of the loop is determined by the time accuracy factor on each node. Hence, set the time accuracy to 15 or greater on the CIU module through the CIU utilities by connecting a terminal to the CIU termination unit. See the CIU manual for details on how to use the CIU utilities.
