14.4 Machine Parameters for the Data Interfaces
The detailed functions of the machine parameters are explained in the TNC Manual for Machine Tool
Manufacturers and in the information on the data interface
In the operating modes
ME, FE1 and FE2, the interface parameters are fixed. In the operating modes
and
EXT2, the interface parameters may be determined via machine parameters
machine parameters for the data interfaces are user parameters, i.e. they can be selected with the
code number 123.
14.4.1 Machine Parameters for the “Standard Interface”
(e.g. for ME 101, printer)
MP for
5020.0
5030.0
5201
MP for Entry Values Function
5020.1 168 7 data bits, transfer stop by DC3, parity bit (even
parity), 1 stop bit
5030.1 0 Standard data interface
5201 3 Control character for end of program = ETX
The data format and the type of transfer stop must be set at the printer according to the values
of MP5020.0 and MP5020.1.
MP for MP for EXT2 Entry Values Function
5020.0 5020.1 168 7 data bits, transfer stop by DC3, parity bit (even
parity),
1 stop bit
5030.0 5030.1
5200.0 5201.1
5201 .O 5201
5202.0 5202.1
Blockwise Transfer
Control character for program start = STX
Control character for end of program = ETX
1. ASCII character for data input = (e.g. H =
NC program in HEIDENHAIN plain language)
5203.0 5203.1
5204.0 5204.1
2. ASCII character for data input = E
1. ASCII character for data output = (e.g. H = NC
program in HEIDENHAIN plain language)
5205.0 5205.1 65” 2. ASCII character for data output = A
5206.0 5206.1 ASCII character for start of command block = SOH
5207.0 5207.1 ASCII character for end of command block = ETB
5208.0 5208.1 ASCII character for positive acknowledgement = ACK
5209.0 5209.1 212’ ASCII character for negative acknowledgement = NAK
5210.0 5210.1 ASCII character for end of transfer = EOT
1) ASCII characters are only valid for the transfer of NC programs.
2) If these machine parameters are programmed with 0, the standard values apply.
14.4.2 Machine Parameters for “Blockwise Transfer”
(e.g. for FE personal computer with HEIDENHAIN data
transfer software)
