The current volume flow and totalizer 1 can be displayed on the basis of these meas- ured variables. Data transfer from Promag to the automation control system The input and output bytes are structured in a fixed sequence.
  • Page 49 Promag 50 PROFIBUS-PA 4 Commissioning Example: The concentration is calculated in % f in the automation control sys- (temperature/density) tem. The temperature and density status is transferred with the two cyclic measured values and can therefore be shown directly in the automation control system together with the calculated concentration.
  • Page 50 4 Commissioning Promag 50 PROFIBUS-PA Control variables for the totalizer (output data) These functions allow the totalizer to be controlled from the automation control system. The following control variables are possible: totalizing, resetting, activation of a prede- fined value, balancing, positive flow detection, negative flow detection and stopping of totalizing.
  • Page 51 Promag 50 PROFIBUS-PA 4 Commissioning Caution: • It is essential that the following sequence be adhered to when configuring the meas- ured variables – volume flow, totalizer, display value and control! • The device will have to be reset once a new measured variable has been configured.
