OVERVIEW

DESCRIPTION

The RP C-320 is a n embed ded contr oller with a built in Basic language. Several featur es make it suitable as a stand alone un it:

Built in RPBASIC-52 programm ing language supports hardware using single commands . On card flash EPROM programm er can save up to 8

progr ams to 62K , or about 500K tota l.

High speed multimode counter accepts quadrature or single inputs. Program mable for up/dow n, binary, divide-by-N, X1, X2 or X4 quadr ature counting.

LCD charac ter and gr aphic display a nd keypad p orts for operator interface.

Two R S-232 ser ial ports, one of whic h is configurable for RS-422/485.

Watchdog timer resets card if a program "crashes" .

34 digital I/O lines, 9 of which are high curre nt outputs. 24 of these lines c an connec t to an opto rack or o ther TT L devices.

Eight channel, 12 bit resolution analog to digital converter . Configurable operational amplifiers allow you to signal condition inputs or measure temperature.

32K, 128K, or 512K RAM battery backable to save process variables and other data when power is off.

32K or 512K flash EPRO M to save program s and data.

The RPC -320 uses an 80C320 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. 0" size with 4 mounting holes makes it easy to mount in a NEMA box. Compactness is enhanced by on-board analog and digital terminal strips.

RPBA SIC-52 p rogr amm ing language is standard . T his language is a version of the original Intel BASIC-52. It was m odified for the RPC -320 for c ontrol, data acquisition applications, and on board har dware fea tures.

Program development can take place on your PC, using your word processor, or on the RPC - 320 . Programs

from your PC are downloaded using a serial communication program .

MANUAL ORGANIZATION

This m anual pro vides all the infor mation r equired to install, c onfigure , an d opera te the RP C-320. Using this manual you will be able to:

Interface the RPC -320 to your IBM compatible PC or ter minal.

Understand the operation of the RPC - 320 hardware using RPBASIC-52 programming software.

This manual assumes you are fam iliar with some type of BASIC progr amming software. The syntax used by RPBASIC-52 is similar to BASIC-52. If you are not experie nced with a ny BASIC softwar e, y ou may w ant to refer to books and training program s available through your local book store. The BASIC-52 Programm ing Manual has information and examples for the original commands. Comm ands unique or modified by

RPBA SIC-52 a re in the Sof tware Supplem ent in this manua l.

Each chapter or section is written to first provide an overview. Then, m ore specific information is provided. Each chapter has some examples using Basic. A summar y of related hardware com mands is at the end of most chapters.
