Geo MACRO Drive User and Reference Manual
Geo Macro Drive MI-Variable Reference 133
GEO MACRO DRIVE MI-VARIABLE REFERENCE
The Geo MACRO Station is set up through its own set of initialization I-variables, which are distinct
from the I-variables on PMAC. Usually, they are referenced as MI-variables (e.g. MI900) to distinguish
them from the PMAC’s own I-variables, although they can be referenced just as I-variables.
These MI-variables can be accessed from the Turbo PMAC2 Ultralite/UMAC MACRO through the on-
line
MS{node#},MI{variable#}
read and
MS{node#},MI{variable#}={constant}
write
commands, or the
MSR{node#},MI{variable#},{PMAC variable}
read-copy and
MSW{node#},MI{variable#},{PMAC variable}
write-copy commands (either on-line or
background PLC), where
{node#}
specifies the MACRO node number (0 to 15),
{variable#}
specifies the number of the Station MI-variable (0 - 999), {constant} represents the numerical value to be
written to the Station MI-variable, or
{PMAC variable}
specifies the value to be copied to or from the
Station MI-variable.
For most Station MI-variables, the
{node#}
specifier can take the number of any active node on the
station (usually the lowest-numbered active node). These variables have
MS{node}
in the header of
their descriptions below.
However, there are several node-specific MI-variables. These variables are in the range MI910 to MI939.
For these variables, the node specifier must contain the specific node number for the MACRO node they
affect. These variables have
MS{node}
in the header of their descriptions below.
Global MI-Variables
MS{node},MI0 Geo MACRO drive Firmware Version (Read Only)
Range: 1.000 - 9.999
Units: Revision numbers
This variable when queried, reports the revision number of the firmware installed in the Geo MACRO
drive
Example:
MS0,MI0
1.006
MS{node},MI1 Geo MACRO drive Firmware Date (Read Only)
Range: 01/01/00 – 12/31/99
Units: MM/DD/YY
This variable, when queried, reports the date of implementation of the firmware on the Geo MACRO
drive. The date is reported in the North American style of month/day/year with two decimal digits for
each.
The PMAC command MSDATE, which polls this value, turns the year into a 4-digit value before
reporting the value to the host computer.
MS{node},MI2 and MI3 (Reserved for future use)
Range: 0
Units: none
Default: 0
