HART Status Inhibit
(1797-OE8H)
When this bit is set (1), the HART communication status is not shown
in the realtime data table. The appropriate areas are cleared with
zeroes.
Range: 0 = normal, 1 = inhibit HART.
50/60 Hz Filter
(1797-OE8H)
Range: 0 = 50 Hz, 1 = 60 Hz.
HART Read Back
Threshold
(1797-OE8H)
Delivers the percentage value (in steps of 1%) of the threshold for
forcing the HART read back indication (input signal deviation
HART/Analog) with a 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 from I/O module (set to 5
internally), 5…31 = percentage threshold data (5…31%).
