- RS232/RS4xx RxD
Process input data is data that is transmitted from the connected
field device via the BL20-1RS××× module to the communication
partner (e.g. PLC). The data received from the device by the BL20-
1RS××× module is entered in a 128 byte receive buffer and then
transferred in segments to the communication partner via the
module bus and the gateway.
This is transferred in an 8-byte format as follows:
6 bytes or 7 bytes are used to contain the user data.
1 byte contains the diagnostics data depending on the param-
eter setting.
1 status byte is required to ensure trouble-free transmission of
the data.
