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 5/01
t 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
r -AT or XT, a Compaq r
Portable, Portable II, Deskpro
t 286, 386/SX, 386, a Tandyt 3000HL,
Toshiba
t 3100E, or GATEWAY 2000t models 386DX/25, 386DX/33,
486DX/33, and 486DX2/50 personal computer. Your computer must have:
•
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
