Process output data is data that is output from the communication
partner (e.g. PLC) via the gateway and the BL20-1RS××× module to
the field device.
The data received from the communication partner in the BL20-
1RS××× module is entered in a 64 byte transmit buffer.
This is transferred in an 8-byte format as follows:
6 bytes or 7 bytes are used to contain the user data.
With the corresponding parameters, 1 byte contains signals for
triggering the clearing of the transmit and receive buffer.
1 control byte is required to ensure trouble-free transmission of
the data.
