Programming Parameters
5-74
Parameter 915 – Trend 1 Contiguous Trigger Switch
[Tr 1 Cont Trigger]
Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 1
Default Value: 1
Description: This parameter specifies the type of trend. The choices
are One Shot Trend, 0 = Once the trigger condition is true, and the
number of samples after the trigger is taken (as programmed in 914)
are gathered, the trend will halt.
Continuous Trend, 1 = Once the trigger condition is true, and the
number of samples after the trigger is taken (as programmed in 914)
are gathered, the trend will continue looking for the next occurrence
when the trigger condition is true.
Parameter 916 – Trend 1 Enable Trend [Tr 1 Enable]
Internal units : None
Programming Terminal units: None
Minimum Value: 0
Maximum Value: 1
Default Value: 0
Description: This parameter is a switch that enables (activates) or
disables (de-activates) the trend. The choices are:
Disable, 0 = Immediately terminates the trend (if it is activated).
Enable, 1 = Starts the trend provided a link has been established with
the corresponding Trend 1 Input source fast parameter. Otherwise,
the trend is automatically disabled.
Parameter 917 – Trend 1 Output Transmit Rate [Tr 1 Output Rate]
Internal units : 1 = 0.001 secs
Programming Terminal units: Secs
Minimum Value: 0.004
Maximum Value: 30.0
Default Value: 0.040
Description: This parameter specifies the rate at which ordered,
sampled data (indicating the trend has triggered and taken post
samples) is copied to the Trend Fast source parameter and
subsequently transferred to the configured fast sink parameter
number. It is programmable in 4 ms increments. All values are
rounded down to the nearest 4ms.
Parameters 920 to 927 are identical to parameters 910 to 917 for
Trend Buffer 2.
Parameters 930 to 937 are identical to parameters 910 to 917 for
Trend Buffer 3.
Parameters 940 to 947 are identical to parameters 910 to 917 for
Trend Buffer 4.
