System variables can be used to read and write internal NC data such as
tool compensation values and current position data. Note, however, that
some system variables can only be read. System variables are essential
for automation and general–purpose program development.
Signals can be exchanged between the programmable machine controller
(PMC) and custom macros.

(When the parameter MIF (bit 0 of No. 6001) is set to 0.)
Variable
number
Function
#1000 to #1015
#1032
A 16–bit signal can be sent from the PMC to a custom macro.
Variables #1000 to #1015 are used to read a signal bit by bit.
Variable #1032 is used to read all 16 bits of a signal at one
time.
#1100 to #1115
#1132
A 16–bit signal can be sent from a custom macro to the PMC.
Variables #1100 to #1115 are used to write a signal bit by bit.
Variable #1132 is used to write all 16 bits of a signal at one
time.
#1133 Variable #1133 is used to write all 32 bits of a signal at one
time from a custom macro to the PMC. Note, that values from
–99999999 to +99999999 can be used for #1133.
(When the parameter MIF (bit 0 of No. 6001) is set to 1.)
Variable
number
Function
#1000 to #1031 A 32–bit signal can be sent from the PMC to a custom macro.
Variables #1000 to #1031 are used to read a signal bit by bit.
#1100 to #1131 A 32–bit signal can be sent from a custom macro to the PMC.
Variables #1100 to #1131 are used to write a signal bit by bit.
#1032 to #1035 Variables #1032 to #1035 are used to output all 32 bits of a
signal at one time from the PMC to a custom macro. Note,
that values from –99999999 to +99999999 can be used for
#1032 to #1035.
#1132 to #1135 Variables #1132 to #1135 are used to write all 32 bits of a sig-
nal at one time from a custom macro to the PMC. Note, that
values from –99999999 to +99999999 can be used for
#1132 to #1135.
