T1.317 Command Language
The Pulsar Plus controller 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 controller.
Objects and Attributes
The T1.317 standard organizes system parameters called attributes into groups called objects. All
commands, objects, attributes and ranges for their respective parameters for the controllers 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” and “administrator” 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.
