Operation Using an Interface
Switchgear can also be controlled using a connection to the substation control system. For that, the required
periphery must exist in the device and in the substation. Furthermore, certain settings for the interface need to
be made in the device (see SIPROTEC 4 System Description/1/).

Command Types

In conjunction with the power system control several command types can be distinguished for the device.

2.4.2.1 Description

Commands to the Process
These are all commands that are directly output to the switchgear to change their process state:
• Switching commands for controlling the circuit breakers (not synchronized), disconnectors and ground elec-
trodes
• Step commands, e.g. raising and lowering transformer LTCs
• Set-point commands with configurable time settings, e.g. to control Petersen coils
Internal/Pseudo Commands
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-dependent objects such as an-
nunciations and switching states, e.g. if the communication with the process is interrupted. Manually over-
ridden objects are flagged as such in the information status and can be displayed accordingly.
• Tagging commands (for "setting") of the information value of internal objects, for example switching authority
(remote/local), settings group switching, data transmission block and deleting/presetting metered values.
• 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
