Table 14 shows the tags for GuardLink1. These tags apply to input IN1, which
is wiring terminals S12 and S22. GuardLink2 has the same tags, but the tags
apply to input IN2, which is wiring terminals S32 and S42.
Definition
Active Status - Indicates whether the GuardLink circuit is used on IN1.
0 = IN1 is used for standard OSSD or EMSS inputs. When the Active value is zero, all remaining GuardLink tags are zero.
1 = IN1 is used as a GuardLink input.
Tripped Status - Indicates whether the GuardLink circuit is operational or in a tripped state.
0 = Operational
1 = Tripped
Diagnostic Active - Indicates whether the GuardLink circuit is in a diagnostic state.
0 = All GuardLink taps are not in a faulted (diagnostic) state.
1 = One or more GuardLink taps are in a faulted (diagnostic) state. The tap indicators are flashing red. See
for more information.
Diagnostic Code - See Table 19 on page 76
Fault - Indicates whether the GuardLink circuit is in a fault state. See
0 = No Fault
1 = Fault
Fault Code - Indicates the fault code when the GuardLink circuit is faulted. See
Device Trip - When all nodes are operational, DeviceTrip is the same as DeviceCount. When nodes are tripped, DeviceTrip shows a
value that reflects all nodes that remain operational. Bit values of zero indicate the nodes that are tripped.
With four operational nodes, the decimal value is 15. If nodes 1 and 3 are tripped, the decimal value is 10. If only node 2 is
tripped, the decimal value is 13.
Status Decimal
All Operational 15
Nodes 1 and 3 10
tripped
Node 2 tripped 13
Device Diagnostic - Indicates the nodes whose diagnostics are active.
0 = No nodes are in diagnostics.
Device Fault - Indicates the nodes that are faulted
0 = No nodes are faulted.
For example with four nodes, a 6 means that node 1 and node 4 are faulted.
Device Count - Provides the number of nodes in the GuardLink1 circuit.
For example, a 15 means the GuardLink system has four nodes.
