Set protocol
(protocol no. 106702)
The data transfer protocol controls the data flow of a serial
transmission (comparable to MP5030 of the iTNC 530).
Operating notes:
The BLOCKWISE setting designates a type of data
transfer in which the data is transferred grouped in
blocks.
The BLOCKWISE setting does
data reception in blocks nor to the simultaneous
execution of older contouring controls in blocks. This
function is no longer available for current controls.
Data transmission protocol
Standard data transmission (transmission
line-by-line)
Packet-based data transfer
Transmission without protocol (only charac-
ter-by-character)
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 helps the receiver to detect transmission errors. The
parity bit can be formed in three different ways:
No parity (NONE): There is no error detection
Even parity (EVEN): Here there is an error if the receiver finds
that it has received an odd number of set bits
Odd parity (ODD): Here there is an error if the receiver finds that
it has received an even number of set bits
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.
