T1.317 Command Language - ABB CPS6000 Product Manual

T1.317 Command Language

The QS840A command language is based on the T1.317 standard. This section describes the
commands, objects and attributes used to access measurements, configuration, and control
parameters in the QS840A controller.
Objects and Attributes
The T1.317 standard organizes system parameters called attributes into groups called objects. Note
that all commands, objects, attributes and ranges for their respective parameters for the QS840A
controller are given in the following tables.
An object-attribute pair uniquely identifies a measurement, configuration, or control parameter. For
example, the object-attribute pair "dc1,vdc" identifies the plant voltage while the object-attribute pair
"dc1,adc" identifies the plant load current. In each of these examples "dc1" identifies the plant object
and "vdc" and "adc" identify DC voltage and DC current, respectively.
There are three main commands involved with plant operations in the system controller command set.
The command "sta" is used to get the status of the plant, the command "cha" is used to change a plant
parameter, and the command "ope" is used to initiate a plant function. A person at the "user" level can
only perform the sta operations. A person at the "super-user" level can also perform the cha and ope
operations.
Instructions in the T1.317 command set take the following form: command object,attribute
[=parameter].
Certain commands do not require a value for parameter, while others do. Note that text parameters are
to be enclosed in quotation marks while numeric parameters are not to be enclosed in quotation
marks.
For example, to obtain the plant voltage, type in the following command: sta dc1,vdc
To enable low-temperature slope thermal compensation, type in the following command: cha sc1,rve=1
To change the voltage at which the LVD contactor disconnects the batteries from the load to 40V, type
the following:
cha cn1,dth=40
To initiate a manual boost charging, i.e., place the plant into boost charging mode, type in the
following command:
ope dc1,stt="boost"
The tables below summarize the object-attribute pairs in the system along with the commands that
can be used with the pair and the valid range that the attribute may have. The values in bold text are
the default settings for the attributes.
