CHAPTER 1 OVERVIEW

RPC-30 Page 1

DESCRIPTION

The RP C-30 is an embedded contro ller with a built in

Basic language. Several features make it suitable as a

stand alone unit:

Built in CAMBASIC programming language

autoruns at power up. On card EEPROM

programmer saves programs to 30K.

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 I/O.

LCD and keypad ports for operator interface. A

built in speaker can produce alarm or annunciation

tones.

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

configured for RS-422/485.

Watchdog timer resets the card if the program

"crashes". The timer is enabled and disabled by

software.

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 -30 uses a Z180 CPU operating at 18 Mhz. It

can operate stand alone or on a network using the RS-

485 port. Its 4.5" x 7" size makes it easy to mount in a

NEM A box. C ompactness is enhanced by the 4 on-

board opto module slots.

CAM BASIC programm ing language is standard . T his

language was adapted for the RPC-30 for

control and data acquisition applications. A complete

description of CAMBASIC commands is in the

CAMBA SIC Programming Guide.

Program development can take place on your PC, using

your word processor, or on the RPC-30. 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-30. Using this

manual you will be able to:

Interface the RPC-30 to your IBM compatible PC or

terminal.

Understand the operation of the RPC-30 hardware

using CAMBASIC programming software.

This manual assumes you are familiar with some type of

BASIC programming software. The syntax used by

CAM BASIC is similar to Microsoft' s GW or

QuickBASIC. If you are not experienced with BASIC

software, you may want to refer to books and training

programs available through your local software store.

The CAMBASIC Programming Manual has information

and examples for all command s.

NOTE: The RPC-30 uses a Zilog Z180 processor.

Additional information can be obtained from Zilog,

(408-370-8016), or your distributor.
