The operator addresses for the control of the other relays are stored on the subse-
quent addresses. In the case of an operation via the membrane keyboard, a once
entered password is memorized until the address block is left. In the case of an ope-
ration via DIGSI, the password has to be entered again for each control action (relay
on or off).
If the device has a system port and uses this for communicating with a control center,
you can test with the DIGSI device operation whether indications are correctly trans-
mitted. You must avoid to use this test possibility during live operation.
Danger!
The sending or receiving of annunciations via the system port by means of the test
function is a real information exchange between SIPROTEC and the control center.
This information would execute the corresponding functions (e.g. follow-up com-
mands) in the control center.
The port test is made in the DIGSI mode Online:
Double-click the directory Online. The operating functions for this device will ap-
pear.
