WAGO-I/O-SYSTEM 750 Function Description 750-652 Serial Interface RS-232 / RS-485 If continuous transmission is activated, the I/O module evaluates the bit SC in control byte 0. Only when SC takes the value 1 does the I/O module transmit the data contained in the output buffer to the serial interface. The application can set SC to 0 to prompt the I/O module to accumulate data in the output buffer.

WAGO-I/O-SYSTEM 750 Function Description 750-652 Serial Interface RS-232 / RS-485 5.1.4 RS-485 Operating Mode The RS-485 operating mode in half-duplex is realized in a 2-wire multi-endpoint (bus) connection. Simultaneous transmission and receiving is not possible with 2-wire connections. The I/O module switches to receive mode after transmitting the content of the input buffer to the serial interface completely.

WAGO-I/O-SYSTEM 750 Function Description 750-652 Serial Interface RS-232 / RS-485 The cycle, in which process data is exchanged between I/O modules, is event driven. The I/O module only starts the next transmission after assessing the transmission of the opposite side as error-free. The I/O module then also begins a new transmission if no error-free transmission has been received from the opposite side for a period of at least 200 ms.
