DELTA PLC INTRODUCTION?

 Delta PLC Comes in different series of PLC

AH Series PLC:
The AH Series Comes with Modularized hardware structure An abundant selection of extension modules, gives the AH series PLC Exceptional system expandability, greatly reducing the system cost for a broad range of application

DVP PLCs could be further classified in 2 series.

E Series The supply is usually AC.

S Series (Slim Series ) The supply is usually DC.

Max I/O points 256

* Program capacity 4K steps

* Built in RS 485 for almost all devices, compatible with MODBUS ASCII RTU Communication protocol.

* High Speed pulse output.

* High speed counters.

Word Level Addressing's

Data Register:

For General

DO-D199,200 Points.

For Latched

D200 - D999, 800 Points. D2000 - D4999, 3000 points.

For Special

Addressing Constant's

Constants:

There decimal constants are prefixed by the alphabetical "k" and Hexadecimal constants are prefixed by "H". for example in the second ring of the following program "Y3" will be on when DS >= 12 (DS Greater than equal to 12).
