T-60 Operator's Manual

T-60 Overview

The T-60 Operator Interface Terminal allows you to set up and operate EMERSON EMC positioning servo drive products. The T-60 provides overall control and operator interface for any type of controller or computer which needs an easy to use, intelligent operator interface.

With a T-60 an operator can view and change machine parameters or follow instructions to perform operations. Operators do not have to set switches, thumbwheels or indicator lights. A back-lit 8 line by 40 character “super-twist” LCD display and a large full-travel 30 key waterproof keypad prompts and “listens” to the operator through machine operations. By programmming the Help functionkey, operators have as little or as much “HELP” information as required. The T-60’s LCD screen displays TEXT or GRAPHICS providing the operator with block diagrams, flow charts, wiring diagrams and statistical information.

For machine control, the T-60 provides 8 lines of parallel I/O, two serial ports (one is software configurable to be either RS-232 RS-422, or RS-485), and 8 timers to facilitate machine monitoring and control functions. All I/O’s are optically isolated and designed to be extremely noise tolerant.

Included with the T-60 is a disk containing the ApplicationBuilder; a PC DOS program which allows you to quickly generate programs for the T-60. The ApplicationBuilder generates BASIC programs from simple menu selections and direct screen entry of text. It consists of three components:

BUILDER - converts menu selections and direct screen text entry into

•

BASIC code

EDITOR - performs text editing of BASIC or other ASCII files

•

TERMINAL EMULATOR - performs “dumb” terminal operation to talk

•

to the T-60.

Integrated into all ApplicationBuilder functions is an UPLOAD/DOWNLOAD capability and a comprehensive, context sensitive HELP system.

Functional Description

The T-60 is housed in a rugged cast housing which can be flush mounted to an equipment panel. A full gasket and a rigid mounting system forms a water tight seal about the opening. The display is sealed and the keypad is constructed of a water tight silicone rubber. If being water tight is not critical to your application, the T-60 can be wall mounted with supplied brackets.

The keypad on the front of the T-60 is organized into three color coded groups:

WHITENumeric Entry BLUE Action - CURSOR, ENTER, INSERT, DELETE, HELP YELLOW Function Keys

Functional Description

Introduction

The 8 line by 40 character LCD display serves as a display port, programming tool and soft key label. In the edit mode, the display can be used to scroll through text, make changes, or debug programs. In the run mode text, soft key titles and graphics can be displayed under program control.

The bottom of the T-60 incorporates the entire connector system for parallel and serial I/O.

Figure 1 diagrams the internal components of the T-60. The heart of the unit is a high speed 64180, 8 bit high integration CPU chip. The CPU communicates with UARTS (serial ports), ROM, RAM, TIMERS, and I/O. Battery backed-up RAM stores programs and variables even if the power is removed. It can hold a program for over 5 years without power applied. The opto-isolation circuitry is designed to provide a barrier between the outside world (I/O ports) and the CPU. This eliminates CPU errors in high noise environments. The serial and parallel ports have their own power supply to further insure that noise does not disrupt the CPU’s operation.

T-60 Operator's Manual

Installation

This chapter focuses on the steps necessary to unpack and install the T-60. Read this section before attempting to apply the T-60. System installers should read this chapter before attempting to install the unit into a cabinet, or before connecting any electrical power to the T-60.

Unpacking and Inspection

Inspect the T-60’s shipping container. Is there evidence of damage or mishandling? If damage exists contact your shipping carrier immediately. EMERSON EMC cannot be held responsible for damage in shipment. Compare the contents of the container with the packing list which is attached to the exterior of the shipping container. Your T-60 shipping container should include the following:

Panel Cut-Out

Through Panel Mounting

The T-60 is designed to be mounted either through an equipment panel (in a panel cut-out) or on a flat surface. The through-panel mounting will allow the T-60 to meet NEMA4 specifications for water resistance, and will also resist dust, dirt and non corrosive chemicals. Improper installation could result in damage to the T-60 and other equipment installed in or adjacent to the panel containing the T-60. For safety reasons please follow these instructions closely.

1. Prepare the opening in the panel. a. Tape the enclosed mounting template to the front of the panel in

the desired location (see Figure 2). b. Drill 3/8 “ inside the cutout to facilitate cutting. c. Use a sabre saw or some other type of sheet metal cutting device

to cut out along the ”cut here" line. d. Using a file, carefully remove any burrs or rough edges that may

cut or scratch during the remainder of the installation. e. Remove the paper template and discard.

2. Carefully insert the T-60 into the hole in the panel from the front side (see Figure 3).

3. Hold the T-60 to the panel, and insert the mounting clips as shown in

4. Tighten the mounting clips to secure the T-60 to the front panel.

5. Inspect that the T-60 fits snugly up against the front panel, and that there

that the installer apply a silicone sealer to the gasket prior to installation.

are no gaps or holes that may allow water or dirt to enter the cabinet.

System Interconnect

The T-60 is designed to meet a variety of applications; therefore, it is impossible to describe a “standard” interconnect for the T-60. This section will describe each individual connector on the T-60 and how to apply them.

Power / RS422 Connector

The Power/RS422 Connector is an 8 pin screw terminal type connector which provides the DC input power and the RS422 / RS485 connections. The T-60 can accept from 9V to 30V DC at 6 watts. The T-60 actually tries to begin working as soon as the power source passes 4.5 V. This means that at start-up the current requirements from the DC power source can exceed 1.3 Amps. This current surge may cause some power sources to enter current limit rather than to begin working. For this reason it is recommended that the T-60 be used with a power source which is uneffected by this type of current surge. Unregulated supplies, linear power supplies, or high current (2 Amp) switching supplies are recommended.Only connect the DC power source to the DC IN + and the DC IN -. These inputs are reverse protected. DO NOT connect the DC power ground to LOGIC GROUND. Logic Ground, as with all I/O is optically isolated from the I/O. Connecting Logic Ground to DC IN - will result in lower noise immunity.

For connections to the RS422 connector, refer to section “RS422 and RS485 Connections”.

IBM PC-XT Keyboard Connector

An industry standard IBM PC XT keyboard can be connected into the 5 pin DIN connector on the bottom panel of the T-60. Some keyboards have switches which select XT or AT mode. Be sure that the switch is in the XT mode. Some “auto-switch” type keyboards may not work with the T-60. If the keyboard you select is an universal keyboard, make sure it has a switch.

Note that the IBM KEYBOARD connector is not optically isolated, and use in a high noise environment should be avoided. The primary use for this connector and the IBM keyboard is for program development. If necessary, remove the keyboard from the connector while running your application.

COM1 and COM2 Connectors

COM1 and COM2 are the serial port connectors (DB-9 style, male). The pin-outs for these connectors are as follows:

COM1 and COM2 Connectors

Pin-Outs

RS232 Minimum Connections

Pin: Connection:

Housing SHIELD

2 RS232 RECIEVE (INPUT) 3 RS232TRANSMIT (OUTPUT) 5 SIGNAL GROUND

These connectors provide connection for serial communications between the T-60 and a variety of devices. Connections made with this connector are most commonly referred to as SERIAL PORTS. Examine your application carefully, and make sure that you have TRANSMIT on the T-60 connected to the RECEIVE of the device under control, and RECEIVE of the T-60 connected to the TRANSMIT of the device under control.

RS422 and RS485 Communications

The T-60 can communicate via RS422 or RS485 on COM1. When either of these modes are selected, the RS232 COM1 connector is disabled. To use the RS422 connections, follow the same conventions outlined for RS232, connecting outputs on the T-60 to inputs on the device under control, and inputs on the T-60 to outputs on the device under control. To enable the RS422 transmitter, refer to the RS422 Statement in the EMERSON EMC Basic Programming Guide. Figure 7 depicts proper RS422 connections.

T-60 Operator's Manual

Figure 7

RS422 Connections

To perform RS485 serial communications with the T-60, the RS422 transmitter and receiver lines must be tied together. Since the RS422 transmitters are disabled after power up, it is safe to assume that no line driver conflicts will occur. Again, refer to the RS422 Statement in the EMERSON EMC BASIC PROGRAMMING GUIDE. The electrical connection between the T-60 and the device under control are shown in Figure 8.

Figure 8

RS485 Connector

System Interconnect

I/O Connector

The I/O connector on the T-60 is designed to provide 8 bits of parallel I/O. Each line can be configured in software to perform input, output, or bidirectional operations. The pin-out is an industry standard 20 pin ribbon cable, compatible with industry standard PB-8 boards. Pinout as follows (even numbered pins - logic ground):

Installation

I/O Connector Pin-Out

Pin: Function:

19 +5V DC OUT* 17 I/O 0 15 I/O 1 13 I/O 2 11 I/O 3

9 I/O 4 8 I/O 5 5 I/O 6 3 I/O 7

The schematic in Figure 9 represents one I/O bit on the 8-bit I/O interface. All of the other 7 bits are identical. U1 is a CMOS receiver which is constantly monitoring the status of the I/O line. Its input is current limited by R2 and pulled up by R1. A current limit (R2) is needed to allow the I/O pin to exceed the supply voltage of U1 without damage. Notice that the pull-up (R1) is a fairly high value (22K ohms). This allows the user to connect any voltage from 5 to 30VDC to the pin without damage to the pull-up resistor. U1 senses a logic high (1) on the I/O pin at 3.2 V and a logic low (0) on the I/O pin at 1.4 V regardless of the externally applied pull-up voltage.

U2 is an open collector output driver which can withstand 30 V and 30 MA load. When a BASIC program writes a 1 to the output port, U2 is off, allowing the pull-up resistor (R1) or the user’s externally connected pull-up to pull the I/O line high. It is possible in this condition for an external device like a switch to pull the line low thereby allowing the input U1 to sense a logic low. When a BASIC program writes a 1 to the output port, the output transistor in U2 turns on, thereby driving the I/O line low. When the T-60 powers up, all I/O lines are driven to a 1, thereby allowing the I/O pins to operate as inputs.Use the OUT and INP commands to program the T-60’s 8 bit I/O port. They are described in detail in the EMERSON EMC BASIC PROGRAMMING GUIDE.

T-60 Operator's Manual

Figure 9

One Channel of the 8 Bit I/O

Support for the T-60’s 8 bit I/O has been provided by the following commands. Some commands refer to 24 bits of I/O instead of 8. This reflects the compatability between the T-60 and the T-61 (the T-61 has 24 bits of I/O standard while the T-60 has 8 bits of I/O). The T-60 can only use the lower 8 bits of these commands.

INP Input port data

IO24 Specify an I/O bit pattern to generate an interrupt. ON IO24 Interrupt on an I/O bit pattern OUT Output port data

These commands are described in the EMERSON EMC BASIC USERS GUIDE in a manner which works with both the EMERSON EMC T-61 and T-60. The specific changes are as follows:

INP Input range of 0 to 255.

IO24 Bit pattern ranges: “0”, “1” or “X” through “00000000”,

“11111111”, or “XXXXXXXX”. the input may still be a string variable.

ON IO24 Unchanged.

OUT Output range 2 to 255. The MAP function works over

the range of: “0”, “1” or “X” through “00000000”, “11111111”, or “XXXXXXXX”.

There are similar restrictions on the use of the EVENT DRIVEN SOFTWARE. I/O ranges are limited to 8 bits. If you have questions about the EVENT DRIVEN SOFTWARE and the T-60, please contact EMERSON EMC.

ApplicationBuilder

Included with your T-60 is a disk containing the ApplicationBuilder, a PC program which allows you to quickly generate programs for the T-60. The ApplicationBuilder generates BASIC programs from simple menu selections and direct screen entry of text. It consists of three components: the BUILDER, which converts menu selections and direct screen text entry into BASIC code; the EDITOR which performs text editing of BASIC or other ASCII files; and a TERMINAL EMULATOR which can perform “dumb” terminal operation to talk to the T-60. Integrated into all ApplicationBuilder functions is an UPLOAD/DOWNLOAD capability and a comprehensive, context sensitive HELP system.

Getting Started

Running the ApplicationBuilder is quite simple, and requires no special software skills. First you must connect the T-60 to your PC. Connect one end of the NULL MODEM cable to COM2 on the T-60 and the other end to an available serial port on your PC (either COM1 or COM2). Note which serial port on the PC that you have connected to (for information on the serial ports for your PC refer to your PC’s instruction manual).

ApplicationBuilder

Getting Started

Figure 10

Serial Connections

The ApplicationBuilder is supplied on two 5 1/4" diskettes and on one 3 1/2" diskette. Make back-up copies of your diskettes before attempting to use them. Save your original ApplicationBuilder diskettes in a safe place.

T-60 Operator's Manual

If your system has a hard drive, copy the contents of either of the diskettes onto the hard drive (make a separate directory first for ease of use). If you do not have a hard drive, place the disk labeled DISK 1 into your diskette drive.Log onto the drive with the ApplicationBuilder on it (i.e.. type A: or B: or C: followed by Enter). Type BUILD followed by Enter to run the ApplicationBuilder. If you wait a few minutes and your screen remains blank, remove the disk and reboot your computer. Re-run the ApplicationBuilder by logging onto the dirve containing the ApplicationBuilder and typing BUILD X followed by Enter.

The ApplicationBuilder will start up for the first time in LCD mode (the simplest display mode). If your computer has a color monitor, selecting the SETTINGS menu by pressing ALT-S, and choose the COLOR selection by moving the cursor to the COLOR text followed by ENTER. This will display ApplicationBuilder screens in color. The change you have just made will be recorded to a configuration file on disk, so subsequent operation of the program will be in color.

To select the COM port on your PC which is connected to the T-60, press ALT-S to pull down the SETTINGS menu. Choose either COM 1 or COM 2 depending upon which port the null modem cable is connected to on your PC. Perform the selection in the same manner described above. Again, the settings will automatically be saved for you when you exit the ApplicationBuilder program.

Figure 11

Builder Mode Screen

Figure 15 shows the layout of the BUILD screen. It is comprised of four basic components. At the top there is the MENU BAR. This is where the pull-down menus for operating the ApplicationBuilder originate. In the center is the PSEUDOCODE GENERATION area. This is where English language program statements which we call PSEUDOCODE are placed and edited. In the lower left is the SIMULATION of the T-60’s screen. This represents the 8 line by 40 character LCD screen on the T-60. The lower right contains descriptions for the function keys. These keys are used to generate the PSEUDOCODE.

ApplicationBuilder

Getting Started

Simple Example

To demonstrate the power of the ApplicationBuilder, a very simple example program will be read from disk, viewed, converted to BASIC, downloaded, and run.

Select the FILE menu (ALT-F) and OPEN (move the cursor or type O) followed by ENTER. You will see a window appear which contains a listing of the demonstration builder files on the ApplicationBuilder diskette. Move the highlight to EASY.BLD and press ENTER. The PSEUDOCODE for EASY.BLD will appear on the screen. Scroll up and down through the PSEUDOCODE with the cursor keys. Here is a listing of the PSEUDOCODE for EASY.BLD:

- GOTO SCREEN begin *>SCREEN begin

- PUT TEXT AT (7,7): “PRESS THE ‘MORE’ SOFTKEY”

- PUT LARGE TEXT AT (3,3): “TO THE BUILDER”

- PUT HUGE TEXT AT (2,1): “WELCOME”

- SOFTKEY (1) “MORE” GOTO SCREEN morescr

- SOFTKEY WAIT *>SCREEN morescr

- PUT LARGE TEXT AT (3,1): “EMERSON EMC”

- PUT LARGE TEXT AT (2,2): “MAKES PROGRAMMING”

- PUT HUGE TEXT AT (3,2): “EASY!!”

- DELAY 2000

- GOTO SCREEN begin

- END OF PSEUDOCODE

Observe the first two lines and the last line of the PSEUDOCODE. These three lines are automatically inserted by the BUILDER. You may have noticed them on the screen before you retrieved EASY.BLD from disk. These lines cannot be deleted, edited or moved. They are essential for the builder’s operation. Notice that each line begins with a dash (-) or a * sequence. These tell the BUILDER that the line is PSEUDOCODE, and what to do with it.

A line starting with * is a new screen, while a line starting with a dash is PSEUDOCODE that will execute for that screen. Don’t worry about generating these special symbols, the BUILDER does that for you.

Next move the cursor (blinking block) over the “*SCREEN begin” PSEUDOCODE. Notice that the SIMULATION OF THE T-60’S SCREEN contains text. This is the text which will be placed on the T-60 actual screen when BASIC is generated and the program is run on the T-60. Now try placing the cursor over the fourth line:

- PUT TEXT AT (7,7): “PRESS THE ‘MORE’ SOFTKEY”

Press ENTER. Notice that the “PRESS THE ‘MORE’ SOFTKEY” is highlighted on the T-60’s screen. If you hold down the SHIFT key and move the cursor key, the text block will move on the screen. Notice that the two numbers in parentheses are changing. This action changes the place where the BUILDER will place the BASIC text string when the PSEUDOCODE is converted to BASIC.Press ESC (leave the program unchanged). If you were to press ENTER, new position would have been saved.

T-60 Operator's Manual

Press SOFTKEY F5. This is how you select PSEUDOCODES to place on screen. Type an S. Press ENTER. The SCREEN PSEUDOCODE has been selected. This allows you to type text directly on the screen. Press ESC (leave the program unchanged).

Press SOFTKEY F8. This softkey generates BASIC. You may be asked if you wish to write over the existing BASIC program: answer “Y” for YES or press ENTER (if the ApplicationBuilder has been used before, the file EASY.BAS may already exist on the disk). Notice that the number of basic lines generated are displayed on screen during this process. You will be asked if you want to load the BASIC program into the EDITOR, answer YES. You will be asked if you want to save EASY.BLD, answer NO since you did not change anything (or mean to change anything!).

The BASIC program generated by EASY.BLD is now loaded into the EDITOR. The EDITOR has the normal attributes of a text editor. CUT / PASTE / INSERT / etc. To select a block of text to cut or copy, move the cursor to the start of the text block and hold down the shift key and move the cursor to the end of the block. The selected block will be highlighted. You may now CUT copy COPY the text in the selected block by using the functions in the EDIT menu. Try pressing F1 to further examine the capabilities of the EDITOR. After examining the BASIC code generated, let’s download it into the T-60.

Press ALT-T and select Download Disk File (by selecting it and pressing Enter or by typing “D”). Select EASY.BAS and press ENTER. This begins the download process from the PC to the T-60. While data is transferred between the PC and the T-60, a counter will show the number of bytes being transferred. When the process is complete, the program has been downloaded. Press F1 (RUN) on the T-60. You should see the screens and softkeys that were present on the SIMULATION OF THE T-60’S SCREEN on the PC.

Once you have successfully downloaded and run EASY.BLD, try loading, examining, and compiling other programs on the ApplicationBuilder diskette. Some programs are only available in BASIC form. They may be loaded with the ApplicationBuilder even though their corresponding BUILDER file is not present.

Trouble-Shooting Communications

If your attempt at down-loading a program to the T-60 was unsuccessful, check the serial port connections between the T-60 and the PC. Look for the following things:

1. Is power applied to the T-60?

2. Is one end of the NULL MODEM cable connected to COM 2 of the T-60?

If it is not, reconnect it to COM 2.

3. Which port on the PC is the other end of the serial cable connected to:

COM 1 or COM 2? Does this match with the selections made in the SETTINGS menu? If you are unsure, recheck the SETTINGS menu (ALT-S) and make sure that you have the correct setting.

4. Are the NULL MODEM cable connectors securely seated into their

respective sockets? Try tightening the hold-down screws on the NULL MODEM cable.

5. Are you using the NULL MODEM cable supplied by EMERSON EMC?

If not, check the cable for correct configuration.

6. Do you have memory resident programs loaded (TSR programs) which

are presently running on your PC (disk spoolers, communications drivers, etc.)? If so disable or remove them. TSR’s may cause problems with the serial port operation.

Operating Modes

This portion of the manual has been created from excerpts of the on-line HELP which is integrated into the ApplicationBuilder program. If you feel comfortable with the discussion so far, go ahead and try the ApplicationBuilder on your own. If you need help at any time, press F1. A help message will appear which will describe the operation required to run the ApplicationBuilder. After trying out the ApplicationBuilder, read this section of the manual to master its power. Section “Summary of ApplicationBuilder” contains a keystroke summary.

ApplicationBuilder

Operating Modes

The ApplicationBuilder consists of three basic operating modes: BUILDER, EDITOR, and the TERMINAL modes. These modes are selected by the MODE menu. When the ApplicationBuilder begins, it starts up in the BUILDER mode. To change modes, use the MODE menu. The Mode menu gives you access to the Builder, the Editor, and the Terminal Modes of the ApplicationBuilder. You can switch from mode to mode without closing the current document allowing you to work on a number of things at once. You also quit the program from the Mode menu. You can access the Mode menu by hitting the <Esc> key or Alt-M.

BUILDER - The Builder Mode is the mode you utilize to use a user friendly program generation environment to help you develop your BASIC program to run on your T-60. Typing “B” while anywhere in the Mode menu will also

activate this command.

EDITOR - The Editor Mode is basically a standard text editor where you can develop and modify your BASIC programs. Not only can you cut, copy, and paste blocks of text, but you can also renumber your BASIC programs in the Editor. Typing “E” while anywhere in the Mode menu will also activate this mode.

TERMINAL - The Terminal Mode basically turns your computer into a dumb terminal that communicates directly to the T-60’s interface. For all practical purposes, key strokes entered onto your computer keyboard are echoed on the interface screen. Typing “T” while anywhere in the Mode menu will also activate this command.

RUN TUTORIAL - This selection provides a guided tour of the ApplicationBuilder. Text will be placed on-screen with examples of how to run the ApplicationBuilder.

QUIT - Exits the ApplicationBuilder program and returns you to DOS. Typing “Q” while anywhere in the Mode menu will also activate this command.

T-60 Operator's Manual

Builder Mode

The Builder Mode is the heart of the ApplicationBuilder package. It allows you to easily develop a control and interface program, test the operator interface functionality of the program, and then generate the proper BASIC code to run in a T-60. You accomplish this by generating “Pseudocode”. You can enter a line of Pseudocode by pressing F5, finding the appropriate Pseudocode for the task you want to accomplish, pressing Enter, and following the instructions for entering the requested data. You write a program in Pseudocode that represents what you want the interface and control program to do. Not all of the functionality of the Emerson BASIC is represented in Pseudocodes. At any time in the process of generating the program you find that you need functionality that the current Pseudocodes don’t provide, you can press F6 and enter BASIC directly. Once you have a Pseudocode (and possibly Basic) representation of what you want your program to do, you press F8 which converts your Pseudocode program into a line numbered BASIC program.

The EDITOR functions are available while operating the BUILDER. You can cut and copy text blocks from one section of your Pseudocode to another. Refer to the EDITOR for operation examples.

Operating the Builder

The box in the lower left hand corner of your computer screen is a representation of your T-60’s screen. While you are generating your Pseudocode program, any line of code that generates information that will be displayed on the LCD display will show up here. Text, soft key labels, placeholders for variable and operator numeric entry will all show up and can be moved to any legal location you desire. You will find that as you move the cursor down from Pseudocode line to Pseudocode line, the screen will build up one line at a time in synchronization with the Pseudocode line you are on.

There are a few other important keys and keystrokes to keep in mind. Ctrl-Y will delete the line of Pseudocode where the cursor is currently located. Cut, Copy and Paste are all functions which allow blocks of Pseudocode to be manipulated. Pressing F5 when the cursor is on a line of Pseudocode will add a new line of Pseudocode above the cursor location. Pressing Enter while on a line of Pseudocode will allow you to edit that line.The Pseudocode you generate will be organized into Screens. Each screen will have a name (defined by the SCREEN Pseudocode). The GOTO screen and SOFTKEY Pseudocodes will allow your program to move from screen to screen. F2, F3, and F4 help you navigate through your Pseudocode program as you are developing it. If you are on a line of Pseudocode that defines a GOTO or GOSUB to a screen or a label and press F2, the cursor will move to the beginning of that screen or to that label. F4 will send you to the beginning of the next screen definition. F3 will send you to the beginning of the previous screen definition. These function keys become increasingly helpful as your programs get longer and more involved.

ApplicationBuilder

Builder Mode

Entering Pseudocode falls into two categories: Entering/placing text on the screen and everything else. Pseudocodes that have nothing to do with text on screen are relatively simple. Each bit of information needed to complete a Pseudocode command is asked for one piece at a time. You can get from entry to entry with the Tab key or the Enter key. The Enter key causes you to exit the Pseudocode entry box once everything has been defined. The Tab key takes you from entry to entry and from the last entry to the first without exiting the screen. Shift-Tab takes you backwards.On Screen entry allows you to do even more powerful things. Any command that generates text to be placed on the screen takes advantage of On Screen Editing. The SCREEN command allows you to place regular text, large text and huge text at any location on the screen. When entering text on screen, you are always in overtype mode. You change text sizes with the Tab key. Once you are done typing the text to be displayed on the screen, you press Enter and are then prompted for a name for the screen. Once that is done (and you press Enter again) you will see that a series of PUT TEXT commands have been generated. Whenever you are entering a new PUT TEXT command or editing an existing one, your cursor will be on the screen. You can add or change text or move it around. To move text, you hold down the Shift key and then press Cursor keys to move the text to the desired location. Once you have the proper text on the screen in the proper location, press Enter to generate the Pseudocode.

Certain Pseudocodes (like PUT NUMBER) allow you to specify numeric formats for printing numbers on the screen. You may specify a digit place holder with a # character. Use the decimal point (.) character for specifying the location of the decimal point. Use a plus(+) or minus (-) sign to specify the use of a sign. If you want scientific notation, use an E. For example:

##.### Specifies from 0.000 to 99.999

+#.# Specifies from -9.9 to +9.9 ### Specifies from 0 to 999

PUT TEXT has the capability to place text from string variables directly on screen. The actual process to place the variable may seem a little confusing at first. To place the contents of a string variable with the PUT TEXT Pseudocode, press F5 followed by P. Select PUT TEXT with the cursor, press Enter. You are now in “ON SCREEN” text entry (i.e. your cursor is on the simulated T-60 screen and blinking). Move the cursor to the desired starting location of the text string. Type a dollar sign ($) followed by Enter. A new window will appear in the Pseudocode entry area which will ask for the name of the string variable (a string variable must end with a dollar sign ($)). Enter the string variable and press return.

Selecting Pseudocode is simple. Pressing F5 displays a list of Pseudocodes that you can choose. The Pseudocode selection screen displays the Pseudocode list, the currently selected Pseudocode, and some helpful information about the currently selected Pseudocode. If you press Enter, you will go to the entry screen (if one is needed) for the currently selected Pseudocode. You can use the Up and Down Arrows, as well as the Page Up and Page Down keys, to scroll through the Pseudocodes. You can also press a letter key to get to the first command in the Pseudocode list that begins with that letter. For instance, if you are in the list and press S, you will go to the SCREEN command location in the Pseudocode list.

T-60 Operator's Manual

Editor Mode

Editor Mode is a text editor allowing you to edit files off line from any serial device (such as a T-60.) This allows you to write and modify programs away from your machine and to use more powerful editing features than BASIC has built in. With the Editor, you can easily Cut, Copy, and Paste blocks of text from one area or program to another. You can even cut or copy text in the Editor and paste it into the Builder and vice versa.

To select text to cut or copy, you position the Cursor at one end of the block of text in question. Then hold down the Shift key as you move the cursor with the Arrow keys and Page up/Page down keys. You then select Cut or Copy from the Edit menu. You can also use Shift-Delete or Ctrl-Insert, respectively, to perform the same functions. You can Paste the text anywhere you put the cursor (or over any block of text you choose) by choosing Paste from the Edit menu or by using Shift-Insert.

When you cut or copy text from a document, it is saved in the “Clipboard.” You can view the clipboard at any time by choosing View Clipboard from the Edit menu. You will notice that the last block that was cut or copied is highlighted and that many of the previous cut or copied blocks are still in the clipboard. If you would rather paste a previously cut or copied block of text, just highlight that block, return to your document, and paste that previously (and now currently) chosen text. The following sub menus appear when you select the EDITOR MENU:

CUT - Text removes the currently selected text and places it in the clipboard. It can then be pasted into another location or file. Typing “T” while anywhere in the Edit menu will also activate this command.

COPY - Text takes a copy of the currently selected text and places it in the clipboard. It can then be pasted into another location or file. Typing “C” while anywhere in the Edit menu will also activate this command.

PASTE - Text takes the currently selected text from the clipboard and pastes it into the currently selected location in your document. Unless you explicitly select otherwise in the clipboard, the text that is pasted will be the last block

of text cut or copied. Typing “P” while anywhere in the Edit menu will also

activate this command.

SHOW - Clipboard opens the clipboard so you can view its current contents. You can also select text other than the most recently cut or copied text to paste into a document just by highlighting a different section of text. Typing “S” while anywhere in the Edit menu will also activate this command.

RENUMBER - Lines acts just like the BASIC “RENUM” command if you have a BASIC file with a .BAS file extension loaded into the Editor. This will be handy if you have to insert a large number of lines of code into a BASIC program in the Editor. Typing “R” while anywhere in the Edit menu will also activate this command.

Terminal Mode

The Up and Down cursor keys are not currently functional. If you want to move up or down on the screen, you must do it from the cursor keys on your T-60. If you are editing a line of BASIC, use the EDIT command which will position the cursor on the line you want to change.

File Menu

ApplicationBuilder

File Menu

Terminal Mode basically turns your computer into a dumb terminal. Virtually all keys that you hit on your keyboard are sent directly over the serial link from your PC to T-60. Also, anything sent out of the Emerson device’s serial port connected to your PC will show up on the screen of your PC when in Terminal Mode. In effect, using the Terminal Mode to communicate with the T-60 is quite a bit like typing on a keyboard plugged into the keyboard port on your Emerson T-60 (the exception being the use of <Ctrl> and function keys).

If you enter Terminal Mode and have problems communicating, verify that you have the correct COM port selected in the Settings Menu and that you have a null modem cable between that COM port and COM2 on your Emerson product. Once you have verified this setup, select Start Communications from the Terminal menu to get things going.

The File menu is used to manipulate files. You begin a New file, Open a preexisting file, Save a file, save a file under a different name, or Print a file. If you need to get to DOS briefly, the DOS Shell command allows you to go to DOS and get back easily. You can access the File menu by hitting Alt-F. The following selections appear when you select the File menu:

NEW - closes any currently open file and starts a new one. This only affects the currently active mode. Typing “N” while anywhere in the File menu will also activate this command.

OPEN - allows you to close any currently open file and open the file of your choice. You will be prompted to select from a list of acceptable files or you can type in the path and filename directly. Typing “O” while anywhere in the File menu will also activate this command.

SAVE - immediately saves the currently active file to the most recent filename assigned to it. Typing “S” while anywhere in the File menu will also activate this command.

SAVE_AS - saves the currently active file, but it first prompts you to specify a new path and/or file name. Typing “A” while anywhere in the File menu will also activate this command.

PRINT - prints the currently active file to the default printer. Typing “P” while anywhere in the File menu will also activate this command.

DOS SHELL - Selecting DOS Shell will send you back to DOS to take care of some brief task. Typing “exit” will then return you to the ApplicationBuilder. Typing “D” while anywhere in the File menu will also activate this command.

T-60 Operator's Manual

Transfer Menu

The Transfer menu is used to transfer files back and forth between your T-60 and your PC. You can Download from the PC to the Emerson T-60 or Upload from the product to your PC. You can also Verify whether a program in your interface matches one on your PC or not. You can also Start and verify communication between the two devices. You can access the Transfer menu by hitting Alt-T. The following selections appear when you select the TRANSFER MENU:

DOWNLOAD Disk File - transfers a file from your PC to the T-60. You will be prompted to select a currently saved BASIC file, or you can enter in the filename of the program directly. Typing “D” while anywhere in the Transfer menu will also activate this command.

UPLOAD Disk File - transfers a file from your T-60 to your PC. You will be prompted to select a filename for the uploaded file. You can save it as an existing filename thereby overwriting the existing file with the uploaded file, or you can assign a new name to the uploaded file. Typing “U” while anywhere in the Transfer menu will also activate this command.

VERIFY Disk File - compares a selected file on disk in your PC with the file currently loaded in the T-60. This allows you to determine which versions of your BASIC programs exist in the PC and the Emerson T-60. This is useful if, for instance, you are not sure if you have made changes in your program in the Emerson T-60 which are not saved on disk. If you do a Verify Disk File with the latest version you have on disk, and they are different, you know that something has changed in the T-60 since you last downloaded the program. Typing “V” while anywhere in the Transfer menu will also activate this command.

START COMMUNICATIONS - does a number of things that will be useful to you. First, it stops the execution of any program currently running in your T-60. It then enables remote communication and verifies that the communication link is working correctly. Any time you cannot seem to communicate with your Emerson T-60, verify that you have the correct COM port selected in the Settings Menu and that you have a null modem cable between that COM port and COM2 on your Emerson T-60. Once you have verified this setup, select Start Communications to verify the setup. Typing “C” while anywhere in the Transfer menu will also activate this command.

Setting Menu

The Settings menu is used to configure your PC. You can specify the configuration of your PC’s serial ports and which serial port you will be using to communicate with your T-60. You can also configure the ApplicationBuilder to use colors which match the capability of your computer screen. You can access the Settings menu by hitting Alt-S. The following sub menus appear when you select the SETTINGS MENU:

SELECT COM1 - Highlighting COM1 and pressing 07 selects COM1 as the active COM port in your PC for communication with your T-60. Typing “1” while anywhere in the Settings menu will also activate COM1.
