PROGRAMMABLE SCHEME LOGIC SETTINGS

The programmable scheme logic (PSL) settings can be uploaded from and downloaded to the IED using the
block transfer mechanism.
The following cells are used to perform the extraction:
● Domain cell (B204): Used to select either PSL settings (upload or download) or PSL configuration
data (upload only)
● Sub-Domain cell (B208): Used to select the Protection Setting Group to be uploaded or downloaded.
● Version cell (B20C): Used on a download to check the compatibility of the file to be downloaded.
● Transfer Mode cell (B21C): Used to set up the transfer process.
● Data Transfer cell (B120): Used to perform upload or download.
The PSL settings can be uploaded and downloaded to and from the IED using this mechanism. The settings
application software MiCOM S1 Agile must be used to edit the settings. It also performs checks on the
validity of the settings before they are transferred to the IED.

TIME SYNCHRONISATION

The time and date can be set using the time synchronization feature of the Courier protocol. The device will
correct for the transmission delay. The time synchronization message may be sent as either a global
command or to any individual IED address. If the time synchronization message is sent to an individual
address, then the device will respond with a confirm message. If sent as a global command, the (same)
command must be sent twice. A time synchronization Courier event will be generated/produced whether the
time-synchronization message is sent as a global command or to any individual IED address.
If the clock is being synchronized using the IRIG-B input then it will not be possible to set the device time
using the Courier interface. An attempt to set the time using the interface will cause the device to create an
event with the current date and time taken from the IRIG-B synchronized internal clock.
