• Subsys – each subsystem is listed with a blank row. Shared with Madname, if any
• Name – EPICS Signal name, without attribute. (Note equivalent SLC magnet names, for reference, would have IM20 versus IN20, LM21 versus LI21, etc)
• DES Save Val -the setpoint saved value in bold. The next three live value columns and following ACT Save Val column are compared to the DES Save Val.
• CON Live Val - the Configure setpoint live value (for magnets); brown unless differs from threshold, then red
• DES Live Val -the setpoint live value; blue unless differs from threshold, then red
• ACT Live Val -the readback live value; green unless differs from threshold, then red
• ACT Save Val -readback saved value; olive unless differs from threshold, then red
• Three more columns naming the setpoint (DES), readback (ACT) and configure (CON) attribute names. These attribute names can be appended to the Name, separated by ":" to form a complete EPICS name.

Table display behavior / threshold Top

Wiki MarkupFor magnet devices, if a Live Val or ACT Save Val differs from its DES Save Val by greater or less than its check tolerance (obtained from the slc database (TOLS\[LCLSH:2\]) via aida or epics (CHCKBTOL) via channel access, then it will be displayed as red.

For non-magnet devices, if a Live Val or ACT Save Val is more or less than a user settable fraction different from the DES Save Val, it is displayed in red. Here is the equation for threshold comparisons: ratio = value/DES Save Val; if (ratio > 1 + threshold value) or if (ratio < 1 – threshold value), display red. The live value displays are updated at 0.5 Hz for EPICS values and 0.25 Hz for SLC magnet values.
