FEATURES

Fast Scan Time

The EX250/500 uses a 16 bit microprocessor and custom Toshiba integrated circuits to significantly reduce program scan time .

TWO CPU TYPES

The only difference between the EX250 and the EX500 is the CPU card

• Application Memory	EX250	EX500
	4K steps	8K steps
• Execution Speed	1.1 µs/contact	0.75 µs/contact
• Max Local I/O	65 µs/16 bit addition	65 µs/16 bit addition
	256 points	512 points

Advanced Instruction Set

There are 15 basic relay ladder instructions and 64 special function block instructions . The function blocks

include instructions for performing :	• Data Manipulation		• Trig. Functions
• Arithmetic Operations
• Register Logic	•	Comparisons	•	Upper/Lower Limit
• Min/Max/Avg .	•	Step Sequencer	•	Shift Register

•Function Generator: Given x, solve for f(x) where f(x) is interpolated based on a pre-entered set of x, y points.

Flexible Networking

EX250/500's are easily linked to:	• Remote I/O Stations	• Other EX250/500's
• Higher Level Computers

Easy Program Modification

Testing and modifying logic programs is simple . All controllers have :

•	Real time power follow monitor	•	Forced I/O
•	Instruction Search	•	Data Set

•On-line (in Run mode) program edit

Intelligent 1/O Modules

Several intelligent, specialized I/O modules are available :

•	ASCII/Basic Module	•	4 Channel PID Control Module
•	High Speed/Quadrature Input Module	•	Motion/Stepper Control Module

Clock Calendar

The clock calendar function allows data gathering based on time, time scheduled operations, etc. Time is kept by:

• Second

• Day
