The ibaFOB-PlusControl card in combination with ibaPDA is suitable for measurement data acquisiton with free operand/symbol selection.

The data to be measured is requested online by ibaPDA. For this purpose the symbolic names and addresses of all available variables are read from the PLUSCONTROL CP and stored internally in ibaPDA when the connection has been established for the first time. This address book serves as base to select the measuring data using the address book browser.
