8.56. LABEL -- Set or Query one of the Device Labels
This command sets or queries one of the many labels stored in the device. The LABEL command has the
following syntax:
iLABELx,y
where i is the device type and ID, x is the label specifier, and y is the label text (to set the label) or a ?
character (to query the label). The label specifiers are as follows:
Label Specifier Description
D A label for the device itself.
SG A label for the signal generator.
I1-I8, IA-ID Labels for the input channels.
O1-O8, OA-OD Labels for the output channels.
W, X, Y, Z Labels for matrix outputs to EF Bus.
PB0-PB7, WB0-WB7, XB0-XB7, YB0-YB7, ZB0-ZB7 Labels for inputs from EF Bus to submatrices.
PM0-PM1, WM0-WM2, XM0-XM2, YM0-YM2, ZM0-
ZM2
Labels for outputs from EF Bus submatrices to main matrix.
R1, R2 Labels for AEC references.
G0-G3 Labels for logic input groups.
LI1-LI24 Labels for logic input pins
LO1-LO20 Labels for logic output pins
P0-P47 Labels for user presets.
M0-M255 Labels for user macros.
The text of each label can be up to 16 characters long. Labels for presets 0-15 are read-only.
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each time it
is changed. It will retain its value after power-down. Since this command writes to non-volatile memory, there
will be a delay before an acknowledgment is returned.
