DESCRIPTION

The RP C-52 is an embedded contro ller with a built in

Basic language. Several features make it suitable as a

stand alone unit:

Built in RPBASIC-52 programm ing language

autoruns at power up. On card EEPROM

programmer saves programs to 32K.

Four position opto rack accepts G4 and G5 series

modules. The G4 series is the industry standard

digital I/O module. G5 modules are optically

isolated analog.

LCD character and graphic display and keypad

ports for operator interface.

Two RS-232 serial ports, one of which can be

configured for RS-422/485.

Watchdog timer resets the card if the program

"crashes".

24 general purpose digital I/O lines, 8 of which are

high curr ent outputs. These lines can connec t to

another opto rack.

Calendar/clock is battery backed and keeps track of

date and time even when power is off.

32K, 128K, or 512K RAM is battery backed to

save process variables and other data when power is

off.

A serial EEPROM saves program constants in a

secure media.

The RPC -52 uses an 80C552 CPU operating at 22.1184

Mhz. It can operate stand alone or on a network using

the RS-485 port. Its 4.7" x 7" size with 4 mounting

holes makes it easy to mount in a NEMA box.

Compactness is enhanced by the 4 on-boar d opto mod ule

slots and operator interface.

RPBASIC-52 programm ing language is standard. T his

language is a reassembled version of the original Intel

BASIC-52. It was modified for the RPC -52 for co ntrol,

data acquisition applications, and on board hardware

features.

Program development can take place on your PC, using

your word processor, or on the RPC-52. Program s from

your PC can be downloaded using PC SmartLINK or

other serial communication program.

MANUAL ORGANIZATION

This manual provides all the infor mation required to

install, configure, and operate the RPC-52. Using this

manual you will be able to:

Interface the RPC-52 to your IBM compatible PC or

terminal.

Understand the operation of the RPC-52 hardware

using RPBASIC-52 programming software.

This manual assumes you are familiar with some type of

BASIC programming software. The syntax used by

RPBASIC-52 is similar to BASIC-52. If you are not

experienced with any BASIC softwar e, you may w ant to

refer to books and training programs available through

your local software store. The BASIC-52 Programming

Manual has information and examples for the original

commands. Commands unique or modified by

RPBASIC-52 are in the Software Supplement in this

manual.

The RPC-52 uses a Signetics/Philips 80C552 processor.

Additional information can be obtained from Signetics

(800-227-1817), or your distributor. Information about

the 80C552 processor is in data handbook IC20.

MANUAL CONVENTIONS

Information appearing on your screen is shown in a

different type.

Symbols and Term inology

NOTE: Text under this heading is helpful information.

It is intended to act as a reminder of some

operation or interaction with another device that

may not be obvious.

WARNING:

Information under this heading warns you of

situations which might cause catastrophic or

irreversible damage.

W[-] Denotes jumper block pins.

< xxx> Paired angle brackets are used to indicate a

specific key on your keyboard. F or

example < esc> means the escape key.

BASIC uses the decimal convention for designating

addresses and data. There are times, however, when

hexadecimal notation is more convenient to use. The

hexadecimal notation used in this manual and by

RPBASIC-52 is the 'H' character after the number. A

8CH stands for 8C hexadecimal.
