Geo Macro Drive MI-Variable Reference 137
MACROSTASCII255 command, the first “unordered” station in the ring will respond.
MI11 can also be set with the ASCII command STN={constant}. The value of MI11 can also be
queried with the ASCII command STN.
MS{node},MI12 Card Identification (Read Only)
Range: 0 – $FFFFFF
Units: none
Default: $
93596 (603542)
This returns the card part number. The same as the CID ASCII command.
MS{node},MI13 Ring Break Output indicator
Range: 0 – $F
Units: none
Default: 0
In case of a ring break error, MI13 controls the Geo MACRO output lines and only as a safety feature.
Choose what the output state would be in a ring break situation, High (12-24V) or Low (GND) for each
individual output, depending on sinking or sourcing setup. Default MI13 equals 0, so in case of ring
break, all outputs are turned off.
