M Set Code 0 - 31
Returns Set
Code 0 - 31
Command to acquire sets which are not already in coopera-
tive use. Zero or more sets can be identified to be disabled
from the rough grant cycle in the Network Terminal. Those
sets so identified and not already in use are added to the set
or remote lock out sets and returned in the value which is the
now current remote lock out set code as would be returned in
the L command.
N Set Code 0 - 31 Command to free or release remote sets. They are also auto-
matically released if the Network Terminal is not given L
query at least each 5 seconds when supervision active. Sets
which are desired to be freed are entered as elements of a set
code. They are then released. No error is caused by releasing
sets not currently held.
O ? | = [0 - 1] Command which sets/clears/queries supervisor mode. When
set (=1), a periodic L command to poll the state of the
remote lock out rough sets is required to maintain these sets
locked out. If 5 seconds elapses with no such poll, then the
sets are released to the Network Interface Terminal opera-
tion. Supervisor action may be released (the default) by
using a =0 argument. A ? argument allows the current state
to be examined.
P None Returns a numeric code that identifies which pump modules
are assigned as a group for multi-REGEN start/stops. This
matches the grouping defined using the multi-regeneration
path (ID #99) of the regeneration menus. The returned code
has the same meaning as in the B command.
Q [0 - 1048575] Accepts a numeric code that identifies which pump modules
are to be grouped together for common regeneration start/
stops from the display regeneration MULTI menu. The
entered code has the same meaning as in the B command
above.
V ? | = [0 - 1] Query set or clear the CMOS GrpRgnLock flag used to con-
trol access to display Multi REGEN request.
