sample connection of two 0BA6 together

Hello,

in addition of Helmut_13 I would like to take this inquiry once as the reason to give an overviewoverview of the solution variants for this question formulation here in the forum already indicated.

A coupling and/or a data exchange between two or more LOGO!s by EIB bus is an (expensive) variant to which there are already most different discussions in the forum. One SEARCH with the termsterms "EIB Logo" is creating a list ...

Alternatives for a coupling and/or a data exchange between two or more LOGO!s are mademade up to now only overover corresponding I/O-connectionsn reach. Digital exits for this purpose of the data exchange should be withwith high switching frequency carried out as a transistor.

A parallel use (Wiring) of digital and/or analogous input signals is simplestsimplest onto two or more LOGO!s. The next stagestage would be then a data and/or signal or commandcommand transfertransfer of one LOGO! to one or several other LOGO!s by digital and/or analogous signals. Finally two or more LOGO!s can "be coupled" also bidirectionally by means of separate connectionsconnections of inputs/outputs. In this case different variants of the signal leadershipleadership (for example individual, serial or star-shaped) would be then conceivable to the LOGO!-basic-moduls according the application.

Fundamentally the singlesingle functions of the total program functions should be divided up so onto the singlesingle LOGO!-basic-moduls (if several are urgently necessary then now already!), that only a minimum communication and/or a minimum data exchange becomes necessary (for example alarms, triggers and state...). That means in particular the LOGO!-basic-moduls should havehave the processing/evaluation of analog signals within each one and the using of analog signals within each one should transfer digital signals derived only from that to another module (or several other module) to become if these signals are necessary for theirtheir function urgently!!! The transfertransfer of several digital switching-signals (or commandcommand) should occur binary codes around the number of the necessary signalling lines n minimize (codes 2**n transferable). Where appropriate also through a digital signal of a module (aboutabout a or several corresponding entryentry connectionsconnections) several "data records" about the same ones can ("to be requested" transistor-)outputs.

If the requests at those to transferred data become more complex and/or if the number of the lines keeps on being supposed to be minimized, also simplesimple communication protocols can be used then where appropriate. For example as a defined number of impulses withwith which every impulse number corresponds to a commandcommand. Or for example the transfertransfer of a (short) serial data packet (with or without separate clock line). These implementation approaches require, however, corresponding partial circuits in the shared LOGO!-basic-moduls!
