Assign Data Interface; Enable Data Interface - HEIDENHAIN TNC 415 Technical Manual

4.8.1 Assign Data Interface (Module 9100)
Module 9100 assigns one of the serial interfaces to the PLC and configures the transfer parameters.
The interface is also initialized and any errors are reset. The interface is switched to receive mode.
Once assigned to the PLC, the interface is disabled for use by the Input/Output program of the user
interface.
Constraints:
- The assignment of an interface to the PLC is cancelled when the PLC program is recompiled.
- Configuration for 19200 baud is not possible when the other interface is already configured for
38400 baud, and vice versa (irrespective of whether this interface is assigned to the PLC or the
NC).
- Module 9100 only operates within the scope of a Submit Job.
Possible errors:
- The interface is already assigned elsewhere (by the Input/Output program of the NC user
interface).
- The call parameters contain no valid values (0/1 for selecting the interface and defining the transfer
parameters).
- The required baud rate is not possible owing to the configuration of the other interface (see
Constraints).
- The Module was not called from a Submit Job.
Call:
PS B/W/D/K <Interface 0:RS232/1:RS422>
PS B/W/D/K <Transfer parameters 0: from MP5xxx.2 / 1:
from mode>
CM 9100
Error status after call: M3171 =
4.8.2 Enable Data Interface (Module 9101)
Module 9101 cancels the assignment of a serial interface to the PLC and reassigns it to the
Input/Output program of the NC user interface. The receive mode of the interface is cancelled.
Constraints:
- Module 9101 only operates within the scope of a Submit Job.
Possible errors:
- The interface was not assigned to the PLC.
- The Module was not called from a Submit Job.
