Setting technical key

Both a physical IED and an IED object in PCM600 have a technical key. The purpose
of the technical key is to prevent download of a configuration to wrong IED. The
technical key in the IED and PCM600 must be the same, otherwise it is not possible
to download a configuration. Each IED in a PCM600 project must have a unique
technical key. It is therefor not possible to set the same technical key for several IEDs
in the same PCM600 project.
The technical key property in PCM600 corresponds to the IED name
attribute in SCL files. Avoid changing the IED name attribute outside
PCM600, because data in PCM600 might be lost when importing SCL
files.
The IED technical key and the PCM600 technical key must be the
same for successful communication between the IED and PCM600.
When using PCM600 for writing to the IED, it is important that the
LHMI is not in a menu position where settings can be made. Only one
active transaction, from LHMI or PCM600, is allowed at any one
time.
When writing a configuration to the IED, PCM600 checks the mismatch between the
IED object and the physical IED technical key, if any. For communication between the
IED and PCM600 the technical key must be the same. Users have the option to read
the technical key from the IED and update it to PCM600 or write the PCM600
technical key to the IED. The user can also define an own technical key. The error
message displayed due to mismatch between PCM600 and IED technical key is
shown in Figure 5.
