In conjunction with the power system control several command types can be distin-
guished for the device:
These are all commands that are directly output to the switchgear to change their
process state:
• Switching commands for the control of circuit breakers (not synchronized), discon-
nectors and ground electrode
• Step commands, e.g. raising and lowering transformer LTCs
• Set-point commands with configurable time settings, e.g. to control Petersen coils
They do not directly operate binary outputs. They serve to initiate internal functions,
simulate changes of state, or to acknowledge changes of state.
• Manual overriding commands to manually update information on process-depen-
dent objects such as annunciations and switching states, e.g. if the communication
with the process is interrupted. Manually overridden objects are flagged as such in
the information status and can be displayed accordingly.
• Tagging commands are issued to establish internal settings, e.g. deleting / preset-
ting the switching authority (remote vs. local), a parameter set changeover, data
transmission block to the SCADA interface, and measured value setpoints.
• Acknowledgment and resetting commands for setting and resetting internal buffers
or data states.
• Information status command to set/reset the additional information "information
status" of a process object, such as:
– Input blocking
– Output Blocking
