1-6 Module and Development Software Overview

Typical Configurations

The typical configuration of the SLC system that incorporates your BASIC or BASIC-T module depends on whether the module is:

• integrated with a SLC 500 fixed or modular controller.

• programmed directly with an ASCII terminal or programmed

using a personal computer with the BASIC development software, 1747-PBASE.

• communicating with a DH485 network or with an external source through a modem using DF1 protocol.

Module Integration

The module is a single-slot module that is inserted into a slot in the expansion chassis of your SLC 500 fixed controller or an open slot in the 1746 I/O chassis of your SLC 500 modular controller. The module may be inserted in any slot of the 1746 I/O chassis except the first slot of the first chassis, which is reserved for the SLC modular processor.

Typical SLC fixed and modular configurations are shown in the following figures.

4-8 Programming Overview

Create and Edit a BASIC Program

Module execution is controlled through a BASIC program residing in RAM or ROM. You have the option of creating and editing this program.

• on a personal computer using the BASIC development software and then downloading it to the module. BASIC development software uses an MS-DOS compatible personal computer to facilitate editing, compiling (translating), uploading, and downloading BASIC programs. Refer to the BASIC Development Software Programming Manual, publication 1747-PM001, for additional information on the BASIC development software.

• entering the program one line at a time directly to the module using an ASCII terminal. ASCII terminal programming must be done one line at a time.

Enter a BASIC Program Using an ASCII Terminal

BASIC line numbers indicate the order in which the program lines are stored in memory. They are also used as references when branching and editing. Typically you start numbering BASIC programs with line number 10 and increment by 10. This lets you add additional lines later as you work on your program.

Since the computer runs the statements in numerical order, additional lines need not appear in consecutive order on the screen. For example, if you enter line 35 after line 40, the computer still runs line 35 after line 30 and before line 40. This technique saves you from re-entering an entire program if you forget to include a line.

IMPORTANT

After the line number, there may be a combination of BASIC commands, statements, operators, or CALLs. Depending on the logic of your program, there may be more than one statement on a line. If so, each statement must be separated by a colon (:).

To enter a BASIC program using an ASCII terminal:

1. Select the program port using JW4.

Reuse of an existing line number causes all of the information referenced by the original line number to be lost. Be careful when entering numbers in the Command mode; you may accidentally erase some program lines.

Publication 1746-UM004B-EN-P - December 2005

Programming Overview 4-9

2. Connect the ASCII terminal to the selected program port on the

module.

3. Verify that the console device is configured to communicate with

the module (protocol and communication settings).

4. Apply power to your system.

If there is no program in RAM, this appears on the ASCII terminal.

Stop a BASIC Program

To stop a program that is running, press [Ctrl–C].

IMPORTANT

If [Ctrl–C] is disabled, you cannot stop program execution through a BASIC command. You must have jumper JW4 set in the default position and cycle power to stop program execution.

Edit a BASIC Program Line Through an ASCII Terminal

When the module is in Command mode, you can edit the BASIC program that resides in RAM. Editing a BASIC program is done on a line-by-line basis. To edit an existing line in the BASIC program, type

EDIT and the line number of the line to edit as shown on the following

screen:

READY

>EDIT 10

The BASIC program line specified by the Edit command is displayed on the ASCII terminal. You can perform any of the following edit operations.

• Cursor right and left

• Replace a character

• Insert a character

• Delete a character

• Retype a line

The table on the next page lists the BASIC edit operations, their functions, and keystrokes required to perform the edit operation.

Renumber a BASIC Program

When the module is in Command mode, you can renumber the BASIC program that resides in RAM. To renumber a BASIC program, you must enter a REN command at the system prompt [ top of the next page lists the commands, functions, and keystrokes needed to renumber your BASIC program.

IMPORTANT

The REN command updates the destination of GOSUB, GOTO, ON ERR, ONTIME, and ON GOTO statements.

If the target line number does not exist, or if there is insufficient memory to complete the task, no lines are changed and the message on the console screen.

Because the REN command uses the same RAM for renumbering as it does for variable and program storage, available RAM may be insufficient in large programs. You should renumber your program periodically during development instead of waiting until it is completed.

Lithium Battery Replacement, Handling, and Disposal

This appendix contains important information you should know when using lithium batteries.

Battery Replacement

Your module provides back-up power for RAM through a replaceable lithium battery (catalog number 1747-BA). This battery provides back-up for approximately five years. A BAT LOW indicator on the front of the module alerts you when the battery voltage has fallen below the replace battery threshold level.

To replace the lithium battery:

1. Remove power from the SLC 500 power supply.

ATTENTION

2. Remove the module from the chassis by depressing the retainer

clips at both the top and bottom of the module and slide it out.

IMPORTANT

Do not remove the module from the SLC 500 chassis until all power is removed from the SLC 500 power supply.

If the top or bottom retainer clips are broken when removing the module they can be easily replaced. Pry the broken clip(s) off from the bottom with a screwdriver, if necessary. Do not twist off. Snap in the replacement clip. Order Catalog Number 1746-R15 (2 per package).

ATTENTION

1 Publication 1746-UM004B-EN-P - December 2005

Do not expose the module to surfaces or other areas that may typically hold an electrostatic charge. Electrostatic charges can alter or destroy memory.

3. Unplug the battery connector.

IMPORTANT

The module has a capacitor that provides 30 minutes of battery back-up while the battery is disconnected. Data in RAM is not lost if the battery is replaced within 30 minutes.

4. Remove the battery from the retaining clips.

5. Insert a new battery into the battery retaining clips.

6. Plug the battery connector into the socket with the red lead wire

on top and the white lead wire on the bottom.

7. Re-insert the BASIC module into the SLC 500 chassis.

8. Restore power to the SLC 500 power supply module.

Publication 1746-UM004B-EN-P - December 2005

Lithium Battery Replacement, Handling, and Disposal C-3

Battery Handling

The procedures listed below must be followed to be sure of proper battery operation and reduce personnel hazards.

• Use battery only for intended operation

• Do not ship or dispose of cells except according to

recommended procedures

• Do not ship on passenger aircraft

ATTENTION

Do not charge the batteries. An explosion could result or the cells could overheat causing burns.

Do not open, puncture, crush, or otherwise mutilate the batteries. A possibility of an explosion exists and toxic, corrosive, and flammable liquids would be exposed.

Do not incinerate or expose the batteries to high temperatures.

Do not attempt to solder batteries. An explosion could result.

Do not short positive and negative terminals together. Excessive heat can build up and cause severe burns.

Storage

Store lithium batteries in a cool, dry environment, typically +20 to +25

°C (+68 to +77 °F) with 40% to 60% humidity. Store the batteries

and a copy of the battery instruction sheet in the original container, away from flammable materials.

Transportation

One or Two Batteries

Each battery contains 0.23 g of lithium. Therefore, up to two batteries can be shipped together within the United States without restriction. Regulations governing shipment to or within other countries may differ.

Publication 1746-UM004B-EN-P - December 2005

C-4 Lithium Battery Replacement, Handling, and Disposal

Three or More Batteries

Procedures for the transportation of three or more batteries shipped together within the United States are specified by the Department of Transportation (DOT) in the Code of Federal Regulations, CRF49, “Transportation”. An exemption to these regulations, DOT – E7052, covers the transport of certain hazardous materials classified as flammable solids. This exemption authorizes transport of lithium batteries by motor vehicle, rail freight, cargo vessel, and cargo-only aircraft, providing certain conditions are met. Transport by passenger aircraft is not permitted.

A special provision of the DOT – E7052 (11th Rev., October 21, 1982, par. 8-a) provides that:

Persons that receive cell and batteries covered by this exemption may reship them pursuant to the provisions of 49 CFR 173.22a in any of these packages authorized in this exemption including those in which they were received.

The Code of Federal Regulations, 49 CRF 173.22a, relates to the use of packaging authorized under exemptions. In part, it requires that you must maintain a copy of the exemption at each facility where the packaging is being used in connection with shipment under the exemption.

Shipment of depleted batteries for disposal may be subject to specific regulation of the countries involved or to regulations endorsed by those countries, such as the IATA Restricted Articles Regulations of the International Air Transport Association, Geneva, Switzerland.

Regulations for transportation of lithium batteries are periodically revised.

Publication 1746-UM004B-EN-P - December 2005

Lithium Battery Replacement, Handling, and Disposal C-5

Battery Disposal

The following procedures must be followed when disposing of lithium batteries.

ATTENTION

Do not incinerate or dispose of lithium batteries in general trash collection. Explosion or violent rupture is possible. Batteries should be collected for disposal in a manner to prevent against short circuiting, compacting, or destruction of case integrity and hermetic seal.

For disposal, batteries must be packaged and shipped in accordance with the transportation regulations, to a proper disposal site. The U.S. Department of Transportation authorizes shipment of “Lithium batteries for disposal” by motor vehicle only in regulation 173.1015 of CRF49 (effective January 5, 1983). For additional information contact:

U.S. Department of Transportation Research and Special Programs Administration 400 Seventh Street, S.W. Washington, D.C. 20590

Although the Environmental Protection Agency at this time has no regulations specific to lithium batteries, the material contained may be considered toxic, reactive, or corrosive. The person disposing of the material is responsible for any hazards created in doing so. State and local regulations may exist regarding the disposal of these materials.
