FEATURES
Fast Scan
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
• Execution Speed
• Max Local I/O
EX250
4K steps
1.1 fis/contact
65 ^s/16 bit addition
256 points
EX500
8K steps
0,75 fi.s/contact
65 fis/16 bit addition
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:
• Arithmetic Operations
• Data Manipulation
• Trig. Functions
• 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:
• Higher Level Computers
Remote I/O Stations
• Other EX250/500’s
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 I/O Modules
Several intelligent, specialized I/O modules are available:
• ASCIl/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
• Minute
• Hour
• Day
• Month
• Year
