Description of data exchange module:
The data exchange module allows for the exchange of 4 (5) bytes between dif-
ferent fieldbus systems via multiplexing of a serial connection. The delay
which is caused by the multiplexor is < 5ms. The integrated watchdog function
switches all outputs to zero if there is no valid information for more than 200
ms via the multiplex connection.
The 128 bytes input buffer provides for high rates of data transmission. When
using slower speeds, you can collect the received data with lower priority wi-
thout loosing data.
The 16 byte output buffer provides for faster transmission of larger data
strings.
The data exchange module is connected peer-to-peer. For the wiring of the se-
rial multiplex connection the RxD and TxD cables are crossed. The following
illustrations show the peer-to-peer connection and the internal structure of the
data exchange module.
