134 Geo Macro Drive MI-Variable Reference
MS{node},MI4 Geo MACRO drive Status Word (Read Only)
Range: $00000000 - $FFFFFFFF
Units: Bits
This variable, when queried, reports the value of the current status word bits for the Geo MACRO Station.
The value reported should be broken into bits. Each bit reports the presence or absence of a particular
fault on the Station. If the bit is 0, the fault has not occurred since Station faults were last cleared. If the
bit is 1, the fault has occurred since Station faults were last cleared.

Any of the fault bits that are set can be cleared with the MSCLRF{node} (clear fault) command, or the
MS$$${node} (Station reset) command.

MS{node},MI5 Ring Error Counter
Range: $000000 - $FFFFFF
Units: Error Count
This variable, when queried, reports the number of ring communications errors detected by the Geo
MACRO Station since the most recent power-up/reset.
