Example of communication between several BC9000

ADS-Communication

Data can be sent directly from one BC9000 to another BC9000 using the ADS function blocks from the TcADSBC.lb6 library. ADSREADEX can be used to read data from another BC9000, ADSWRITE can be used for writing. A maximum of 3 BC9000 can be accessed at the same time. In order to communicate with further BC9000s, the connection to at least one BC9000 has to be closed via ADSCLOSE.

Make sure that there are only a maximum of three connections from one BC9000 to other BC9000s. You should reserve the fourth connection for programming.

These connections may also be established by another remote station.

Cross communication only between BC9000 and BC9000 Please note that a BK9000 only allows write access from a master, and that the BK9000 has to be polled regularly at 1 second intervals. It is therefore recommended to use cross communication only between BC9000 and BC9000 and not to BK9000.
