Tip!
PCP communication is not supported.
Parameter data (= Lenze codes) can be changed through a keypad which can be attached to the
controller.
6.1 Process data
6.1.1 Process data assignment
6.1.1.1 General information
Process data are cyclically exchanged between the controller and the master.
They are subdivided into
• Process output data (PO data)
• Process input data (PI data)
Here the data flow starts from the master, i.e. the PO data of the master are input data for the
controller.
The controller gets the control information from the master and returns status information.
Control word and status word
The controller status, such as READY FOR OPERATION, OPERATION ENABLED, etc. are controlled and monitored via the control and status
words. The ranges are subdivided as follows:
• Control word
– The control word is sent from the master to the controller. It includes status information such as OPERATION ENABLED (see chapter 5.4).
• Status word
– The status word is sent from the controller to the master. It provides all actual controller states, such as ERROR.
INTERBUS-Loop can transfer a maximum of 32 bit, which are interpreted by the 2112 fieldbus
module as two process data words. The assignment of the process data words can be preselected
under code C0009.
