Direct Commands from a Computer/PLC
The GSDA-CM-8 is configured with six commands (commands must be in upper case). These
commands are discussed below and on the following pages:
SP
Set Target Speed (or Time in seconds)
Description
Allows the setting of a desired speed (or Process Time)
Format
SP<address>,<speed><CR>
<speed> is usually scaled in Engineering Units; however, in Follower modes, the “speed”
setting is always expressed as a “percent of leader”. Additionally, <speed> is expressed as
seconds when in Time mode. The current program’s “Setting Limits” determine the lowest
and highest values you can use for <speed>.
Example
Set the speed of the
GSDA-CM-8
addressed as “03” to 500
SP03,500<CR>
Response if successful
Y<CR>
Response if unsuccessful
N<CR>
NOTE: The Set Target Speed commands are not stored in non-volatile memory, consequently upon
power-up in Auto Mode, they will revert to zero. When powered-up in Manual Mode, they will revert
to previous number stored in NOV-RAM.
SV
Set Variable
Description
Allows the setting of any parameter to any value within its range.
Format
SV<address>,<parameter>,<value><CR>
<item> and <value> are the same as if you were editing from
the drive front panel. Reference control manual for “Item” and
“Value” meanings.
Example
Set the
GSDA-CM-8
addressed as “06” to set Display Maximum to 1750
SV06,21,1750<CR>
Response if successful
Y<CR>
Response if unsuccessful
N<CR>
NOTE: The SV command can actually be used to great advantage. For example, sending the message
SV00,12,1 to a network of controls with multiple programs, would effectively switch all controls on
the network to that program at one time. An example of such a usage might be in a multiple-auger
materials blender.
