Settings page.
5.5 Vital Link Communications
An Ethernet or Echelon connection may be used to send vital ATCS messages between
GCP5000 (GCE) units. The ATCS messages sent between the GCP5000 (GCE) units contain
15 general-purpose input and output bits. The GCE provides 4 separate vital communication
links, which can be used to communicate with 4 other GCE units. If more than 15 bits are
required between GCE units more than one vital comms link can be used between 2 units.
5.5.1 ATCS Addressing and ATCS Offsets
ATCS Subnode offset number 02 (SS 02) is reserved for the use of the
Spread Spectrum Radio, A53308; SS 16 is reserved for the GCP; and SS
99 is reserved for the SEAR IIi. All other numbers between 03 and 98
may be selected and used as desired.
Because the GCP5000 (GCE) uses ATCS messages for communication, each site must be
programmed with a unique ATCS address (known as the Site Identification Number, or SIN).
The railroad design office usually assigns the ATCS address.
