CON? Condition register
This query returns the contents of the Condition register and clears
its contents. The response is either numeric or a text description
depending on the TEXT ON/OFF setting.
Each bit in this register provides information about the load’ s
condition. A bit being set indicates that the condition is present or
has occurred. Normally the bit will clear when the condition clears
unless its respective bit in the Latch (LAT) register is set.
Furthermore if its respective bit in the Shutdown (SDN) register is
set the load will shutdown.
The returned value will be between 0 and 255 and is the sum of the
individual bit weights. The individual bits are defined below.
