Selecting Your Hardware Components

Selecting Enclosures

Selecting Operator Interfaces

The enclosure protects the equipment from atmospheric contamination. Standards established by the National Electrical Manufacturer’s Association (NEMA) define enclosure types, based on the degree of protection an enclosure will provide. Use a fan to circulate the air of sealed enclosures that use convection cooling to dissipate heat. Select a NEMA–rated enclosure that suits your application and environment. The enclosure should be equipped with a disconnect device. To calculate the heat dissipation of your controller, see appendix D.
Use an operator interface to program and/or monitor your SLC 500 controller. You can choose from several Allen–Bradley operator interface devices.

Programming with a Hand-Held Terminal (1747-PT1)

Use the Hand–Held Terminal (HHT) to configure the SLC 500 controller, enter/modify a user program, download/upload programs, monitor control operation, and test/troubleshoot. When equipped with a battery (1747–BA), the HHT retains a user program in memory for storage and later use.
The display area accommodates 8 lines x 40 characters. You can display five rungs of a user program. The top row of keys are the menu function keys.
Important: Using the HHT, you can program the SLC 5/01t and 5/02t
processors and the SLC 500 fixed controllers. You cannot, however, program the SLC 5/03 processor.
Refer to the Hand–Held Terminal User Manual, Catalog Number 1747–NP002, for information on programming your fixed controller with the HHT.

Programming with Advanced Programming Software (APS) on an IBM Compatible Computer

The Advanced Programming Software (APS) can be used with an Allen-Bradley T45, T47, or T50 terminal, an IBM Portable, Portable II, Deskprot 286, 386/SX, 386, a Tandyt 3000HL, Toshibat 3100E, or GATEWAY 2000t models 386DX/25, 386DX/33, 486DX/33, and 486DX2/50 personal computer. Your computer must have:
r-AT or XT, a Compaqr
• 640 Kbytes of RAM (extended or expanded memory is recommended, but
not required)
• 10 Mbyte fixed-disk drive (APS requires a minimum or 2.5 MBytes of
free disk space.)
• DOS version 3.1 or higher
1–9
Chapter 1
Selecting Your Hardware Components
Advanced Programming Software, 1747–PA2E
APS, Catalog Number 1747–PA2E, comes on 5–1/4 and 3–1/2 inch disks. You must have DOS installed in your computer. You also must have at least 550 Kbytes of free memory to execute the APS software. Like the Hand–Held Terminal, APS lets you configure the SLC 500 controller, enter/modify a user program, restore/save programs to the SLC 500, monitor controller operation, and test/troubleshoot. You can also:
• create and print ladder diagrams, data tables, instruction cross references,
and configurations
• use cut/copy/paste editor
• store multiple programs in the memory of the computer (on the hard disk)
Refer to the Advanced Programming Software User Manual, Catalog Number 1747–NM002, and the Advanced Programming Software Reference Manual, Catalog Number 1747–NR001, for information on programming your fixed controller with APS.
DH–485 Interface Converter (1747–PIC)
For communication, use an RS–232/DH–485 Interface Converter between the computer and SLC controller. The converter includes a 279.4 mm (11.0 in.) ribbon cable, already attached to the converter, for connection to the computer serial port and a Catalog Number 1746–C10 cable for connection to the controller.

Monitoring with a Data Table Access Module (1747-DTAM-E)

The Data Table Access Module (DTAM) is a plant floor device that lets you access data file information, change operating modes, monitor and clear processor faults, and transfer the user program between RAM and an EEPROM memory module with any SLC 500 family processor. You cannot
use it to create new programs.
Important features of DTAM include:
• shorthand addressing, which provides easier access to data files
• display prompts in six, user–selectable languages: English, French,
German, Italian, Spanish, and Japanese
• UL listed, CSA Certified
• NEMA type 12 and 13 enclosures
• point–to–point interface to an SLC family processor, or as a network
device on a DH–485 network
Refer to the Data Table Access Module (DTAM) User Manual, Catalog Number 1747–ND013, for information on monitoring your fixed controller with the DTAM.

Selecting Your Hardware Components

EEPROM and UVPROM Memory Modules

These optional memory modules provide a non–volatile memory back–up in a convenient modular form. The modules plug into a socket on the controller.
You can store (save) your program in the EEPROM by inserting it into the processor and using either the Hand–Held Terminal or Advanced Programming Software.
Use of the UVPROM provides you with an extra degree of program security because the user program cannot be altered while it is installed in the controller. You can program the UVPROM with commercially available UVPROM programming and erasing equipment. You can use an EEPROM module as a master, or you can use an archived processor file as the source by using the APS PROM translator utility.
Adapter sockets are required when inserting memory modules into commercially available PROM programmer. The memory module fits into the adapter socket and then into a PROM programmer.
ATTENTION: Make sure the adapter is inserted properly or damage could result.
