Set protocol
(protocol no. 106702)
The communications protocol controls the data flow of a serial
transmission.
Please note:
The BLOCKWISE setting designates a type of data
transfer in which the data is transferred grouped in
blocks.
The BLOCKWISE setting does not correspond to
the data reception in blocks and the simultaneous
execution of older controls in blocks. This function is
no longer available for current controls.
Setting Data transmission protocol
STANDARD Standard data transmission
Line-by-line transmission
BLOCKWISE Packet-based data transfer
RAW_DATA Transfer without protocol
Transmission of characters only
Set data bits
(dataBits no. 106703)
By setting the data bits you define whether a character is transmitted
with 7 or 8 data bits.
Check parity
(parity no. 106704)
The parity bit defines whether transmission errors are checked.
The parity bit can take three different forms:
Setting Meaning
NONE No parity
There is no error detection.
EVEN Even parity
There is an error if the receiver detects an uneven
number of bits in his evaluation.
ODD Odd parity
There is an error if the receiver detects an even
number of bits in his evaluation.
Set stop bits
(stopBits no. 106705)
The start bit and one or two stop bits enable the receiver to
synchronize each transmitted character during serial data
transmission.
