Description

Orbitscreen is a Motif program to display arrays of process variables from the Advanced Photon Source control system. Although, in principal, any two arrays of process variables may be displayed, the most common use is to display the horizontal and vertical monitor readings. There are three display areas in the interface, one for each of the arrays and a zoom area. In the zoom area both arrays can be displayed at once along with symbols for the major elements of the lattice. There are a number of options to customize the way the values are displayed. It is also possible ... continued below

Description

Orbitscreen is a Motif program to display arrays of process variables from the Advanced Photon Source control system. Although, in principal, any two arrays of process variables may be displayed, the most common use is to display the horizontal and vertical monitor readings. There are three display areas in the interface, one for each of the arrays and a zoom area. In the zoom area both arrays can be displayed at once along with symbols for the major elements of the lattice. There are a number of options to customize the way the values are displayed. It is also possible to: (1) store the current values internally; (2) store the values from a snapshot file internally; (3) display one of the stored sets of values along with the current values; (4) display the difference of the current values with one of the stored sets of values; and (5) write the current values to a snapshot file. The program continuously updates and displays the standard deviation, average, and maximum absolute values for each array and will show the envelope of recent values if desired. The values are sent to the program anytime they change outside of their dead band. If the dead band is chosen appropriately, this should result in less traffic over the control network than if all of the values were polled at fixed intervals. When the display updates, the current values that have been received are displayed. It is possible to manually update all the variables via the Options/EPICS/Rescan menu.
