Command Description
SYSTem SYSTEM subsystem of commands.
:GROup Group mode
:DEFine Used to initially establish groups
:PARallel
Sets the modules to be paralleled.
Rules:
The first (and always the lowest) number in the argument is the
address of the module that will act as master.
The second number (and subsequent numbers) in the argument is
(are) the address(es) of the module(s) that will act as slave(s).
Each module’s address is the right most slot that it occupies in a
mainframe. (The slots of the mainframe are addressed 1 through 12
from left to right). HPAL and LPAL are 3U-wide, thereby occupying 3
slots; hence, a Load module occupying slots 1, 4 and 7, is addressed
as 1.
Valid argument examples:
•
Two modules occupying slots 1 through 3, and 4 through 6:
<1,4>. Address 1 is the master of this group; address 4 is the
slave of this group.
•
Three Load modules occupying slots 1 through 3, 4 through 6
and 10 through 12: <1,4,10>. Address 3 is the master of this
group; addresses 6 and 12 are the slaves of this group. Slots 7
through 9 must remain empty.
The module acting as master accepts SCPI commands for the group.
The current and/or resistance set points for the parallel group will be
set to zero, and the output relays will be open (if option selected), as
a part of setting up a group.
The paralleled group is named 1000+n where n is the address of the
module acting as master of the group.
Additional notes:
Only like-modules can be paralleled (i.e., either High Power Active
Loads or Low Power Active Loads, in this case).
Modules in a group may be in noncontiguous slots of the Mainframe,
but other modules must not be installed in the empty slots between
them.
:DELete
Delete the specific group of modules, i.e., 1000+n where n is the
master of the group.
:DELete:ALL Deletes any and all the groups in the RFP system
:ERRor?
Returns the last error logged in the Error/Event Queue. The
message, “0, No error”, is returned if there are no errors.
