The CMAX plug−in for the FCT helps to carry out all the steps necessary for commissioning a CMAX.
Festo has developed an optimised data profile, the Festo Handling and Positioning Profile (FHPP)", tailored to handling and positioning functions. The FHPP allows the various Festo fieldbus systems and con trollers to be uniformly controlled and programmed. It also uniformly defines the following for the user:...
Using components that have not been approved for oper ation with the CMAX may lead to malfunctions. Use only the special matching components from Festo for setting up and wiring the system. When mounting the components, also observe the mounting instructions in the operating instructions supplied and the instructions in this chapter.
