MMasterDataTxfer - FB Multimaster data transfer

This function block is part of the eMMasterDTxferLib library which makes available a series of functions and FB for the management of multimaster communication on serial line. The possibility to have several master devices communicate on a single RS422/485 serial line allows to speed up the dialogue between the systems optimizing the serial line engagement.
This peculiarity is very appreciated in radio connections, where radiomodems operating on the same frequency can dialogue with each other minimizing the commitment of the band, increasing the time of information transfer.

The function block manages the interface with the defined I/O terminal to manage multimaster communication over a multidrop network. It acts as a communication server managing the I/O device. Client function blocks must then be connected to manage the data exchange between the systems.

For the cost of activating this Function Block entered in MID code, please contact our sales department.
