17.2 Data Exchange between Controllers
When two controllers are connected to one and the same operator panel (dual drivers
are used in the operator panel) it is possible to exchange data (analog and digital sig-
nals) between the controllers. Likewise, two controllers can each be connected to an
operator panel and still exchange data when the operator panels are connected in a
BDTP network. Not available for E1012 and E1022. For addressing, see the section
BDTP. The signals do not have to be of the same type in the two controllers. The
exchange of data takes place in a virtual data channel between controller 1 and 2.
Eight different data channels can be defined. The transfer of data can take place at
intervals or during events. The conditions for how the transfer is made and which
interval of signals are to be transferred for each data channel are specified by double-
clicking on Controller data exchange under the Peripherals folder in the Project
Manager.
Parameter Description
Area Start I/O 1 and Start I/O 2 - Start address for the data channel for
controller 1 and controller 2. (The subsequent fields are used to specify
an index register and signal format. See the chapters Index Addressing
and Signal Format.)
Mode Select if the signals for the data channel are digital or analog.
