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

EX500

8K steps

512 points

• Execution Speed

• Max Local I/O

EX250

0,75 fi.s/contact 65 fis/16 bit addition

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

The compact modular structure of the EX250/500 is designed for easy installation. Diagnostic LEDs are immediately visible, and components can be readily removed and replaced.

CONTROLLER UNIT

The only difference between the EX250 controller and the EX500 controller is the CPU card. The controller unit consists of:

• CPU which contains 1, CPU Card.

2, Power Supply Card. 3, Space for Optional Computer Interface Card

• Backplane which contains space for 8 I/O Modules

DIAGNOSTIC LEDs (RUN, CPU, I/O, PROG, POWER. ВАТТ, COMM, HOLD)

RUN/HALT selector switch

EXPANSION UNIT

The expansion unit consists of a backplane and space for additional I/O modules.

I/o EXPANSION CAPABILITY

EX250

One (1) expansion unit can be connected to each EX250 controller. A total of 16 I/O slots are available. If 32 point I/O modules are used, all the discrete I/O can be located on the controller leaving the expansion unit available for register type I/O (Analog, PID, BCD, etc.)

Local I/O

• 2S6 points or

• 32 registers

EX500

Three (3) expansion units can be connected to each EX500 controller. A total of 32 I/O slots are available. If 32 point I/O modules are used, all the discrete I/O can be located on the controller and the first expansion unit leaving the last two expansion units available for register type I/O (Analog, PID, BCD, etc.).

Local I/O

• 512 points or

• 64 registers

Notes: 1) A 0.5 m expansion cable is shipped with each expansion unit. Optional I m expansion cables are

also available. Total cable length should be less than 2 m.

2) Four types of expansion units are available

EU-6237 480 mm width, 8 ilou, with AC power »upply EU*6257D 480 mm width, 8 slots, with DC power supply EU-6279 390 mm width, 8 slots, no power supply EU-6278 240 mm width, 4 slots, no power supply, tentiiiution only

If total 5 Vdc current consumption will exceed 4.5 A, the expansion unit with power supply

must be used.

NETWORKING

TOSLINE-30/30OP

TOSLINE-30 is an N-to-N data link system dedicated to the EX-series of programmable controllers. The TOSLINE-30 data communication modules allow EX250/500’s to be set-up in a peer-to-peer configuration, master-to-slave configuration, or to use remote I/O.

The optional computer link card allows up to 8 EX250/500’s to be networked on one RS422 serial link back to a personal computer, cell controller, or other higher level computer. The computer can run Toshiba’s EXPDD programming software, various graphics display and data acquisition software, or user designed custom software.
