Issue
Why are points 72 or 136 showing as MISSING in view point status?
Solution
On a D9112B, Points 72 and 136 appear in the Point Status List. Notice that text for Commands 7 and 9 is followed by a MISSING condition on point 72 and pooint 136. Points 72 and 136 serve dual purposes. They are used for Command 7 and Command 9, and they are also used to supervise the data expansion bus. When you see that points 72 and 136 are missing, do not be alarmed. When these points are missing the point bus is normal.
*Note - On a D7212B, only point 72 will show as MISSING.
