January 2012 9.6 Configuring the Serial Interface 1775
Example:
With a transmission format of one start bit, 7 data bits, two stop bits and a data
transfer rate of 300 bps, exactly 30 characters per second will be transmitted.
MP_baudRate
Data transfer rate for LSV2 communication in baud
Available from NCK software version: 597 110-01.
Format: Selection menu
Selection: Use a selection menu to define the transfer rate for the data
transmission. Minimum value is 110 baud, maximum value
115200 baud.
Default: BAUD_9600
Access: LEVEL2
Reaction: NOTHING
Communications
protocol
The protocol of a serial connection means the controlling of the data flow by
feeding reserved ASCII characters into the data stream. Define the
communications protocol of the interface in MP_protocol.
For an overview of all communications protocols available on the control, see
page 1783.
MP_protocol
Communications protocol
Available from NCK software version: 597 110-01.
Format: Selection menu
Selection: STANDARD
Standard data transfer. Data transferred line-by-line
BLOCKWISE
Packet-based data transfer, "ACK/NAK" protocol. Blockwise data
transfer is controlled by the control characters ACK
(Acknowledgment) and NAK (Negative Acknowledgment).
RAW_DATA
Data transferred without protocol. Transfer of characters
without control characters. Protocol intended for transfer of
data of the PLC.
Default: STANDARD
Access: LEVEL2
Reaction: NOTHING
characters per second
300 (Bit/s)
1 + 7 + 2
-------------------------------- 3 0==
Here, the BLOCKWISE setting designates a form of data transfer where
data is transmitted in blocks. This is not to be confused with the blockwise
data reception and simultaneous blockwise processing by older TNC
contouring controls. Blockwise reception of an NC program and
simultaneous machining of the program is not possible!
