Comms changed
This indicates that the setting 2010 Comms Mode has been changed without a subsequent
power off and on.
IEEE C37.94 fail
This indicates a Signal Lost, a Path Yellow or a mismatch in the number ofN*64 channels
used on either channel 1 or channel 2. Further information can be found in the
MEASURMENTS 4 column.
7.5 PSL editor troubleshooting
A failure to open a conn
ection could be because of one or more of the following:
The relay address is not valid (note: this address is always 1 for the front port).
Password in not valid
Communication Set-up - COM port, Baud rate, or Framing - is not correct
Transaction values are not suitable for the relay and/or the type of connection
Modem configuration is not valid. Changes may be necessary when using a modem
The connection cable is not wired correctly or broken. See MiCOM S1 Studio V2
connection configurations
The option switches on any KITZ101/102 this is in use may be incorrectly set
7.5.1 Diagram reconstruction after recover from relay
Although th
e extraction of a scheme from a relay is supported, the facility is provided as a
way of recovering a scheme in the event that the original file is unobtainable.
The recovered scheme will be logically correct, but much of the original graphical information
is lost. Many signals will be drawn in a vertical line down the left side of the canvas. Links
are drawn orthogonally using the shortest path from A to B.
Any annotation added to the original diagram (titles, notes, etc.) are lost.
Sometimes a gate type may not be what was expected, e.g. a 1-input AND gate in the
original scheme will appear as an OR gate when uploaded. Programmable gates with an
inputs-to-trigger value of 1 will also appear as OR gates.
7.5.2 PSL version check
The PSL
is saved with a version reference, time stamp and CRC check. This gives a visual
check whether the default PSL is in place or whether a new application has been
downloaded.
