TDC‑3000 BASIC,AM Application Module CPU,51401551‑300.K2LCN‑3

The Enhanced Micro TDC3000 Control System is furnished with one basic version.  This

is the single US Micro TDC3000.

The base version consists of two 4-node towers, an operator’s keyboard, an engineer’s

keyboard, a color monitor and printer (ordered seperately), and the Advanced Process

Manager.  Four nodes are contained within the two towers:

1. US—UNIVERSAL STATION  A window to the process—allows all information

supplied from process-connected devices, instrumentation subsystems, and

computers to be seen and used.  The color monitor, two keyboards, an optional

touchscreen or trackball, two cartridge disk drives, and the ASPI-41 printer are

integral parts of the Universal Station.

2. AM—APPLICATION MODULE  Performs calculations and control strategies that are

not possible or practical using only process-connected devices.  The Application

Module has 4 or 8 megawords of memory.

3. NIM—NETWORK INTERFACE MODULE  Connects the Enhanced Micro TDC3000

Control System to a process controller, generally to a Advanced Process Manager.

4. HM—HISTORY MODULE  Provides mass storage of software, system data, and

customer/user data.

1.1.2  Options to the System

Monitors, touchscreens or trackballs, and printers are options to all the Universal Stations

in all versions of systems.  A touchscreen or trackball allows you to “point” to areas on the

graphic display and select operations to be performed.  Without either of these options, you

must use directional keys (arrows) on the keyboards to navigate across the screen.

Up to four additional nodes, making a total of eight nodes, may be added to basic

Enhanced Micro TDC3000 Control System.  Choose from the following:

1. NIM—REDUNDANT NETWORK INTERFACE MODULE  Provides a second path to the

process controller in the event of an electrical failure.

2. US—UNIVERSAL STATION  (4Mw and 6Mw) Provides a window to the process.

3. EPLCG—ENHANCED PROGRAMMABLE LOGIC CONTROLLER GATEWAY Provides a

path to one or more Programmable Logic Controllers.

4. PLNM—PLANT NETWORK MODULE Provides the hardware and software to link the

LCN to the VAX interfaces.

5. CG—COMPUTER GATEWAY  Provides a path to a host computer.

6. NG—NETWORK GATEWAY  Provides a path to an alternate network for an integrated

plant solution (single and dual cable)

The Operator’s Keyboard (Figure 1-3) is a flat, chemically resistant, membrane keyboard

installed in a metal frame, placeable by the operator, and connected to the keyboard

connector on the transition panel.  A three-function annunciator horn is built into these

keyboards.

Unmarked keys on the left side of the operator’s keyboard may be configured by the user

(or, perhaps, be preconfigured at the factory).  An insert sheet is available that is placed

between the outside protective membrane and the keyboard electronics.  To replace or

install a new insert, remove the two corner screws beneath the metal frame.  Lift the frame

from the keyboard assembly, grasp the plastic insert using the thumb-slot at the top of the

keyboard and remove it.  Replace it with the new insert.  Reassemble the keyboard and

frame, then install and tighten the two corner screws.

Additional operator’s keyboards are supplied with optional Universal Stations
