Section 4
Setting up a project
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
IEC09000378 V1 EN-US

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.

Be sure that the IED object in PCM600 has the same IP address as the physical
IED, which is intended to be connected through the technical key concept.
The technical key for an IED object in PCM600 can also be changed in the
Object properties window.
