2.24.1.2 Setting Notes

The parameters of the „IBS-Tool" can be set separately for the front operator interface
and the service interface. The relevant addresses are those which relate to the inter-
face that is used for communication with the PC and the „IBS-Tool".
Addresses 4401 to 4406 are to configure the front interface. The valid 12-digit IP
address has the format ***.***.***.***. A three-digit block of the IP address is inserted
into each of the addresses 4401IP-A (A.x.x.x), 4402 IP-B (x.B.x.x), 4403
IP-C (x.x.C.x) and 4404 IP-D (x.x.x.D).
The address 4405 NUM LOCK determines if the devices of a differential protection
system should be operated with the IBS-Tool from the PC. When setting YES, the
devices cannot be operated by the front panel emulation of the PC. This is the normal
state during operation. Once this address is set to NO during commissioning, all
device parameters can be changed to correct, for example, false or inconsistent set-
tings.
In address 4406 LCP/NCP set if your PC interface supports LCP (Link Control Proto-
col) and NCP (Network Control Protocol). In the case of a point-to-point connection,
the setting must be YES (default setting) to allow a data communications link. When
using a star coupler, only one device (master device) requires the setting YES, the
other devices require NO.
Addresses 4411 IP-A (A.x.x.x), 4412 IP-B (x.B.x.x), 4413 IP-C
(x.x.C.x), 4414 IP-D (x.x.x.D), 4415 NUM LOCK and 4416 LCP/NCP. are to
configure the rear interface.
