Remote Control Programming
Overview
All CPS100 models up to 1500VA rated are shipped with standard USB, RS232 and RS485
control interfaces. An optional LAN or GPIB is available for these models. Higher power
models – 3000VA and higher - all include USB, LAN, RS232 and RS485 interfaces. A GPIB
interface option is available for these higher power models as well.
The digital control interface allows the powers source settings to be configured remotely
and measurement data to be retrieved for analysis and test report generation.
Note: For the RS485 multi-drop serial interface, ModBUS protocol is used instead of SCPI
message strings. This communication protocol is covered in a separate manual,
“APS_CPS100_Series_AC_Source_MODBUS_Protocol_Guide-PN160954-10_v1.1.pdf” part
number 160954-10 available for download at
Command Syntax
All CPS100 Series power sources use non-standard SCPI (Standard Commands for
Programmable Instruments) command syntax. The command look SCPI like but don’t meet
the actual SCPI standard and as such should be considered proprietary. Commands are not
case sensitive so any combination of upper and lower case characters is permissible. There
are not long or short versions of these commands, only the commands documented here.
7.2.1
Command Terminators
Allowable terminator characters are:
Character
ASCII
Dec value
Hex value
Carriage Return
<CR>
13
0x0d
Line Feed
<LF>
10
0x0a
All commands should be terminated or they will not be accepted by the power source.
7.2.2
Numeric Parameters
If a command requires a parameter, it must be entered as a real number using a period as
the decimal separator.
7.2.3
Parameter Unit Options
When sending a parameter value, it is
NOT
permissible to include a unit character such as V
for voltage or A for amps. All command parameters and query responses are without any
unit designator characters.
