Chapter 5: Channel Configuration, Data, and Status 53
.HHAlarm
High high alarm bit which is set when the input signal moves above the
configured high high alarm trigger point(HHAlarmLimit). Remains set
until the input signal moves below the trigger point, unless latched via
ProccessAlarmLatch or the input is still within the configured alarm
deadband of the high high alarm trigger point.
.Status
Below are a collection of individual channel status bits. Bits are defined as
follows:
0 – HHAlarm
1 – LLAlarm
2 – HAlarm
3 – Lalarm
4 – RateAlarm
5 – Overrange
6 – Underrange
7 – CalFault
8 – 15 are unused
Module Data Tags The following data tags are preceeded by the tag name
IF8u_Input.ChannelData[x] where x is the channel number 0-7.
.Ch0Data
REAL
The channel 0 input signal represented in engineering units. The input
signal is measured and then scaled based on the user configuration.
.Ch1Data
REAL
The channel 1 input signal represented in engineering units. The input
signal is measured and then scaled based on the user configuration.
.Ch2Data
REAL
The channel 2 input signal represented in engineering units. The input
signal is measured and then scaled based on the user configuration.
.Ch3Data
REAL
The channel 3 input signal represented in engineering units. The input
signal is measured and then scaled based on the user configuration.
.Ch4Data
REAL
The channel 4 input signal represented in engineering units. The input
signal is measured and then scaled based on the user configuration.
.Ch5Data
REAL
The channel 5 input signal represented in engineering units. The input
signal is measured and then scaled based on the user configuration.
