Additional Information
4.1 Block Diagram Description
General
The TNC 150 block diagram shows, in simplified form, the inter-
nal functional units of the control, their relationship to the
various boards, and their interconnections. The graphic layout
of the diagram and the way it is included in single sheets.
- the representation of any of the TRC 150 models (A/AR/P/PR),
- simplified representation of functional processes
Numbers enclosed in dashes inform about the board and its
functional unit.

Simplified Description of the TNC 155 (Block Diagram)
- Keypad Board (1)
- Memory Board (2)
- Main Processor Board (31
- CLP Processor/Graphic Board (4)~
- Analogue Board/Analogue Board TTL (5)
- with SE Board (6) it corresponds to a A(E)-Type;
- without SE Board, with PLC Interface (6). however
- with PLC I/O-Board(s), it corresponds to a P(V)-Type or,
respectively, PR(VR)-Type
- Power Supply Board (7)
- Terminal Board (8)
- Input/Output facilities (e.g. keypad, screen, measuring
system inputs, analog outputs, LBDs, V.24 interfaces etc.)
The functions of the control are divided between the two
microprocessor systems as follows:
1. "Main Processor System"
- Keyboard, LEDs
- User Program Interpreter
- Provision of programming "environment"
- Generation of PLC program addresses
* - Transfer of input and output states between PLC Inter-
face Board, SE Board and PLC RAM
* - Control of the V.24 interface
2. "CLP-Processor System.
- Ascertainment of instantaneous positions
- Interpolation Calculations
- VDU Control
* - Demand Speed Values to DAC
* Serial data transfer via CRU bus.
Main Processor Unit
- Primarily on the main processor board and the memory board.
- The operating system software is held in EPROMs:
-30.1- IC-P4 (not mapped)
-30.3- IC-P5...IC-PS
-30.3- IC-PlO (dialogue language)
Main Proc. Board
-2o- Ic-P1l...Ic-P1S Memory Board
The functional processes of the control are divided between
two microprocessor systems, each comprising:
- Microprocessor (TMS 9995)
- Program Memory (EPROMS)
- Write-Read Memory (RAMS)
