Module of the PA sensors
For the cyclic data traffic, MINITRAC 31 provides the following modules:
•
AI FB1 (OUT)
– Out value of the AI FB1 after scaling
•
AI FB2 (OUT)
– Out value of the AI FB2 after scaling
•
AI FB3 (OUT)
– Out value of the AI FB3 after scaling
•
Free Place
– This module must be used if a value in the data telegram of the cyclical data traffic should not
be used (e.g. replacement of temperature and Additional Cyclic Value)
A maximum of three modules can be active. By means of the configuration software of the Profibus
master you can determine the configuration of the cyclical data telegram with these modules. The
procedure depends on the respective configuration software.
