PLC Simulator

Design

Two cables connect the simulator to the S7-300™ or S7-400™ training unit. The

simulator is divided into the following three sections:

• Binary section with 16 switches/momentary-contact switches and 16 LED's

• Digital section with 4 thumbwheel buttons and a digital display. The

thumbwheel and digital (BCD) display use BCD values,

• Analog section with a voltmeter for displaying the values at analog channels

0 and 1 or the analog outputs 0 and 1. You use the selector switch to choose

the voltage value you want to monitor. There are two separate

potentiometers for setting the values for the analog inputs.

Addressing

You use the following addresses to address the inputs and outputs in your user

program:

Sensor / Actuator	Version A (DI16, DO16)	Version B (DI32, DO32)	S7-400 (Default addresses
Switch / M.C.Sw.	IW 0	IW 0	IW 28
LEDs	QW 8	QW 4	QW 36
Thumb. buttons	IW 4	IW 2	IW 30
Digital display	QW 12	QW 6	QW 38
Analog channels	PIW 352/354	PIW 304/306	PIW 1216/1230
