DESCRIPTION
Allows specific bit statuses to be inserted directly into the InterMiCOM message, to substitute real data. This is used for testing purposes.
Loopback Status 15 52
OK
Fail
SCC Absent
[Indexed String]
Indicates the status of the InterMiCOM loopback mode
OK = Loopback software (and hardware) is working correctly
FAIL = Loopback mode failure
Unavailable = Hardware error present.
INTERMICOM CONF
16 00
This column is only visible if the model number supports InterMiCOM and second rear comms board is fitted.
IM Msg Alarm Lvl 16 01 25
From 0 to 100 in steps of 0.1
[Courier Number (percentage)]
Setting that is used to alarm for poor channel quality. If during the fixed 1.6s window the ratio of invalid messages to the total number of
messages that should be received (based upon the ‘Baud Rate’ setting) exceeds the above threshold, a ‘Message Fail’ alarm will be issued.
IM1 Cmd Type 16 10 Blocking
Disabled
Direct
Blocking
[Indexed String]
Setting that defines the operative mode of the InterMiCOM_1 signal.
Selecting the channel response for this bit to Blocking allows fastest signalling, whereas setting to Direct offers higher security at the
expense of speed.
Selecting the channel response for this bit to Permissive offers higher dependability
IM1 FallBackMode 16 11 Default
Default
Latched
[Indexed String]
Setting that defines the status of IM1 signal in case of heavy noise and message synchronization being lost.
If set to ‘Latching’ the last valid IM1 status will be maintained until the new valid message is received.
If set to ‘Default’, the IM1 status, pre-defined by the user in ‘IM1 DefaultValue’ cell will be set. A new valid message will replace ‘IM1
DefaultValue’, once the channel recovers.
IM1 DefaultValue 16 12 1
0 or 1
[Unsigned Integer(16 bit)]
Setting that defines the IM1 fallback status.
IM1 FrameSyncTim 16 13 1.5
From 0.01 to 1 in steps of 0.01
[Courier Number (time-seconds)]
Time delay after which ’IM1 DefaultValue’ is applied, providing that no valid message is received in the meantime.
IM2 Cmd Type 16 18 Blocking
Disabled
Direct
Blocking
[Indexed String]
Setting that defines the operative mode of the InterMiCOM_2 signal.
Selecting the channel response for this bit to Blocking allows fastest signalling, whereas setting to Direct offers higher security at the
expense of speed.
Selecting the channel response for this bit to Permissive offers higher dependability
IM2 FallBackMode 16 19 Default
Default
Latched
[Indexed String]
Setting that defines the status of IM2 signal in case of heavy noise and message synchronization being lost.
If set to ‘Latching’ the last valid IM2 status will be maintained until the new valid message is received.
If set to ‘Default’, the IM2 status, pre-defined by the user in ‘IM2 DefaultValue’ cell will be set. A new valid message will replace ‘IM2
DefaultValue’, once the channel recovers.
IM2 DefaultValue 16 1A 1
0 or 1
[Unsigned Integer(16 bit)]
Setting that defines the IM2 fallback status.
IM2 FrameSyncTim 16 1B 1.5
From 0.01 to 1 in steps of 0.01
[Courier Number (time-seconds)]
Time delay after which ’IM2 DefaultValue’ is applied, providing that no valid message is received in the meantime.
IM3 Cmd Type 16 20 Blocking
Disabled
Direct
Blocking
[Indexed String]
