Cyclic data exchange
Block model of the Micropilot M
L00-FMR230xx-02-00-00-en-001
The block model shows, which data are exchanged continously (i.e. by cyclic data
transfer) between the Micropilot M and the PLC. The numbers refer to the function
groups and functions:
•
After linearization and integration in the transducer block the "
measured value
"
(000)
is transmitted to the Analog-Input Block. There, it may be scaled and checked for limit
transgression, and is written out over "
OUT value
"
(063)
to the PLC.
•
The function "
select V0H0
" (068) determines whether at the display of the device in
the field for the main measured value the "
measured value
"
(000)
or the value from
the PLC "
display value
"
(069)
are displayed.
Modules for the cyclic data telegram
For the cyclic data telegram the Prosonic provides the following modules:
1.
Main Process Value
This is the main measured value scaled by the Analog Input Block (063).
2.
2nd Cyclic Value
This is the measured distance between the sensor mebrane and the product
surface (0A5) or the measured temperature (030).
3.
Display Value
This is a value which can be transferred from the PLC to the Micropilot M in order
to be shown on the display.
4.
FREE PLACE
This module must be applied during configuration (see below), if the 2nd cyclic
value or the display value are not to appear in the data telegram.
