Reference Signal Evaluation; Installing The Positioning Module - HEIDENHAIN TNC 415 Technical Manual

1.4 Reference signal evaluation

After reference signal evaluation of the NC axes, reference signal evaluation of the PLC axes of the
positioning module must be initiated either automatically (e.g. by NC Start) or manually by special
keys. PLC positioning is not possible until the reference signal is evaluated.

1.5 Installing the positioning module

The positioning module is connected to the hardware across the RS-422/V.11 interface by means of
a special cable (Id.-Nr. 265 479).
Software installation is done with the PLC program of the master controller (TNC 407 or TNC 415).
Modules 9100 and 9107 are used for this: they activate the RS-422/V.11 data interface and make it
possible to transmit and receive binary data respectively.
These modules are described in the chapter "PLC Programming".
The PLC program for the positioning module can be written either on the LE 234.003 itself, in which
case it must be connected up to screen BE 212 and control panel TE 355 A/B, or on a PC using the
HEIDENHAIN PLC programming software.
Please contact HEIDENHAIN should you have any queries about the PLC programming software.
