Setup → Communication
An RS232 interface at the front and an RS485-interface at terminals 101/102 can be selected as
standard. In addition, all process values can be read out via the PROFIBUS DP protocol.
!
Note!
A detailed description of how to integrate the device into a PROFIBUS system can be found in the
operating instructions on the accessory (see Section 8 ’Accessories’):
PROFIBUS Interface Module HMS AnyBus Communicator for PROFIBUS
Hysteresis -99999 to 99999
0.0
Specify set point switch-back threshold to suppress set point
bounce.
Time delay 0 to 99 s
0 s
Time span of limit value violation before it is displayed.
Suppresses peaks in the sensor signal.
Gradient -∆x -19999 to 99999
0.0
Value of signal change for gradient analysis (inclination
function).
Gradient -∆t 0 to 100 s
0 s
Time interval for the signal change of the gradient analysis.
Gradient -reset value -19999 to 99999
0
Switch-back threshold for gradient analysis.
Limit on You can write a message for when the limit value (set point) is
overshot. Depending on the setting, this appears in the event
buffer and the display (see ’Lim. display’)
Limit off You can write a message for when the limit value (set point) is
undershot. Depending on the setting, this appears in the event
buffer and the display (see ’Lim. display’)
Limit dis. Disp.+Ackn.
Not display
Definition of the way of reporting the limit value.
Not display: Limit value violation or violated limit value
undershooting is recorded in the event buffer.
Disp.+Ackn.: Entered in the event buffer and shown on the
display. The message does not disappear until it is
acknowledged with a key.
