| 摘要 |
The invention relates to a device for controlling point-to-point communication between a module (10) and a transmission bus (22), the device comprising a printed circuit (20) which carries the transmission bus (22) and which comprises a connection element (21) intended to connect the module (10) to the transmission bus (22). The printed circuit (20) comprises a communication control unit (23) disposed between the transmission bus (22) and the connection element (21), the said unit (23) comprising unidirectional communication logic gates (24E, 24R), and comprises a logic control circuit (30) for the said logic gates (24E, 24R). Application to programmable controllers.
