Geo MACRO Drive User and Reference Manual
Geo Macro Drive MI-Variable Reference 151
the specified Geo MACRO Node number. The value is reported as a 24-bit number, even though there
are a maximum of 18 real bits in the register (the most significant bits) and existing hardware provides 12
or 16 bits of true input.
MS{node},MI925 Compare A Position Value
Range: -8,388,608 - 8,388,607
Units: Encoder counts
Default: 0
MI925 specifies the value of the ‘A’ compare register of the position compare function for the machine
interface channel mapped to the specified Geo MACRO Node number. The units are encoder counts,
referenced to the position at the latest power-on or reset.
MS{node},MI926 Compare B Position Value
Range: -8,388,608 - 8,388,607
Units: Encoder counts
Default: 0
MI926 specifies the value of the ‘B’ compare register of the position compare function for the machine
interface channel mapped to the specified Geo MACRO Node number. The units are encoder counts,
referenced to the position at the latest power-on or reset.
MS{node},MI927 (Reserved for future use)
Range: 0
Units: 0
Default: 0
MS{node},MI928 Compare-State Write Enable
Range: 0 – 1
Units: none
Default: 0
When MI928 is set to 1, the value of MI929 if forced onto the position-compare output for the channel
associated with the specified node. MI928 is automatically reset to 0 immediately after this occurs.
MS{node},MI929 Compare-Output Initial State
Range: 0 – 1
Units: none
Default: 0
The value of MI929 is forced onto the position-compare output for the channel associated with the
specified node when MI928 is set to 1. After this, each time the channel’s encoder-counter position
matches the value of MI925 or MI926, the output state is toggled.
