Version: B.1
ATCS addresses consist of twelve digits in the format:
7.RRR.LLL.GGG.SS
where:
11
is the wayside equipment type
RRR
is the railroad number (this number is assigned by the ATCS committee for each Railroad)
LLL
is the line number
GGG
is the group number (all equipment at one location has the same group number)
SS
is the subnode number
Each unit at a location has a different subnode number. By default:
16 is assigned to the GCP5000 (GCE) CPU
99 is assigned to the SEAR IIi
03 and higher (03, 04, 05, etc.) is assigned to other collocated GCEs in the same ATCS group
When GCE units are in the same location (locally connected) they should have the same
railroad (
RRR
), line (
LLL
), group (
GGG
), and different subnode (
SS
) numbers.
When GCE units are in different bungalows, the GCE units should have the same railroad
(
RRR
), line (
LLL
) numbers, but different group (
GGG
) numbers. The subnode (
SS
) numbers,
may or may not be different.
The ATCS address is set in the Site Configuration menu as separate ATCS Railroad (
RRR
), line
(
LLL
), Group (
GGG
), and Subnode (
SS
) numbers. The CPU subnode is that used by the CPU
