8.8.3 Dosing operation
When the transmitter recipes have been configured, the active recipe is selected in parameter
2.5.3 "Active Recipe". The transmitter output changes according to the dosing operation and
controls the valve in the dosing process. The digital input can be configured to start dosing.
HMI provides dosing control via the dosing operating view, see Operating views (Page 122).
All dosing setup and control can be performed via bus communication using SIMATIC PDM.
Dosing compensation
In static applications the flowrate is constant. Thus, the dosing compensation, if required, is
fixed. Use the fixed compensation by entering the amount in menu item 2.5.5.5.2 (Fixed
Compensation).
