We are constantly working on the further development of our TNC-controls. It is therefore possible that a
certain control version may deviate from the version described in this manual.
1. General information
The HEIDENHAIN TNC 151/TNC l55-controls are equipped with an integral PLC and are available in two
basic versions:
HEIDENHAINI TNC 151 B/TNC 155 B
These control versions are equipped with a simple interface for connection to an external PLC. This so-
called "standard interface" has remained unchanged since TNC 145, thus making all contouring controls
compatible.
This standard interface has been realized by a PLC-standard program. The following interface description is
based on this PLC-standard program.
TNC 151 B/TNC 155 B is supplied with the PLC-standard program. Certain control functions of this PLC-
standard program can be activated via machine parameters.
HEIDENHAIN TNC 151 Q/TNC 155 Q
Control with a PLC-power board PL 100 B having
.63 inputs, 9 of which have fixed allocations,
.31 outputs
or with PLC-power board PL 110 B having
.63 inputs, 9 o-f which have fixed allocations
25 outputs,
.3 bipolar output pairs
On delivery, this control version also has the standard P LCprogram stored.
By using a further PLC-board PL 100 B or PL 110 B, the PLC-inputs and outputs may be doubled.

TNC 151 F/TNC 155 F, for external PLC.
TNC 151 W/TNC 155 W, with integral PLC and external board
These control versions are identical to the versions TNC 151 B/TNC 155 B and TNC 151 Q/TNC 155 Q with
exception of the functions "transfer blockwise" and 3D-interpolation.
HEIDENHAIN TNC 151.R/TNC 155.R
The suffix R indicates that the control versions has squarewave (TTL) signal inputs. Transducer connections
are via an EXE-digitizing unit.
