Rockwell Automation 1794-OF8IH FLEX Isolated Input/Output HART Analog Modules - Manual (Page 55)

Publication 1794-UM065B-EN-E - September 2010
1794-IF8IH and 1794-OF8IH Configuration 43
High Alarm Limit (8 of 16 Bit)
Sets the limit for the High Alarm in 1 μ A steps. This affects Data Formats
0…7. Steps apply to the 4-20 mA range and 0…20 mA range.
For example, a value of 20000 will cause an High Alarm above 20.0 mA
(20000*1
μ A = 20 mA).
Range: 0…22000 (0=disabled, 1*1 μ A to 22000*1 μ A)
Default: 0=disabled
Data Table Reference: High Alarm Limit, Configuration Words 9, 13, 17, 21,
25, 29, 33 and 37, bits 0…15
HART Disable Channel 0 to 7 (8 of 1 bit)
When this bit is set, the I/O module is inhibiting its HART Communication.
Range: 0= enable, 1= disable
Default: 0
Data Table Reference: HART DISABLE, Configuration Word 1 bits 8…15
HART Current Fault Limit (8 of 5 bits)
Delivers the percentage value (in steps of 1%, starting @ 5%) of the threshold
for causing a HART current fault indication (input signal deviation HART/
Analog) = 31% maximum deviation.
If there is no HART transmitter on the loop or the loop is not in the
transmitter list the function is switched off internally in the I/O module.
Range: 0=disabled, 1…4= not supported by the I/O module. A configuration
request of 1…4 will cause a value of 5 to be utilized by the module. 5…31=
percentage threshold data (5…31%).
Default: 0
Command 3 Disable (8 of 1 bit)
This bit disables the I/O channel from forwarding the associated HART
Command 3 information from the HART Field device through Cyclic EDT to
the adapter.
