Tab.2/7: Overview of the most important blocks of the folder PRM_DPV1_SFC"
Block FB1 is implemented in OB1. Block FB23 for transmitting
parameter sets as well as block FB20 for parametrizing the
SFC−DC via the Festo Parameter Channel (DPV0) are implem
ented in FB1. This is also possible via the blocks FB21 or
FB22.
The global
variables for parametrizing are saved in DB91.
With the aid of the variable table PARAMETERIZE−DRIVE the
controller can be parametrized via PROFIBUS. The diagnostic
memory can be read out with the variable table DIAGNOSTIC
BUFFER.
