Go to Software RSLogix 500 and choose the CPU

First gonna to configure a "Analog Outputs Module" go to side in I/O configuration and select one of the Hardware of AQ, in this example will choose 1762-IF2of2 that include 2 Channels Inputs and Analog Outputs

Remember always is important Configure and Verify if the Analog Outputs will work in 0 10 Volts

For this example and understand how it works, will create a simple Start and Stop and go to create a program for work with Analog Outputs values becoming in a Voltaje Output (Volts)

Let's review the blocks and the important details to consider

• Start-Stop: A simple program using Partir-Parar, always choosing right contacts


• B3:Retention: Remember to use a Start-Stop we need a "Retention", a Binary or flag is an excellent way to create infinite logic control instructions


• MOVE-MOV VERY IMPORTANT in this example, here in the MOV We transform the Signal 0-1 (ON-OFF) in a new output value in a Numeric Value Software


• SCP: The important blocks to Transform and Scale Analog Values from other Numeric Values; these are one of the most important blocks to Scale Analog Inputs and Outputs

Now we know that the blocks "MOV" will transform in this case our signal ON-OFF in Analogic Values, Let's analyze a simple program how create a Output in 0 Volts => 0 y 10 Volts => 32767

The program shows when the Output is "OFF", the second block MOV is activated where the value "Source" is 0 => 0 Volts ; when the program is "ON" will activate the "MOV" Source with value 32767 that means 10 Volts; all this using the blocks "B3:0" in opposite form, using closed and open contacts

All these numeric values are stored in Decimal Integer N7:0, now go to configure "SCP" to finally create our Analog Output

In this example gonna create 2 Blocks SCP

For the First Block

• Scale the value from "MOV" the value to scale is the "N7:0" and in this case gonna have the comparation with the same Software value 0-32767 that is the Analog Outputs Value in Volts that uses PLC Micrologix and Software RSLogix 500


• OUTPUT VALUE assigned this value to REAL ANALOG OUTPUT Q1.0 this means when Software Value is 0 the value in Volts is 0; when the value is 16333 the Output is 5 Volts and when we have Maximun Value 32767 Output will be 10 Volts

For the Second block

• Only Test Block that will use to compare the real Output value O1:0 in real time into other value 0-100 that we can use to compare the 0-10 volts, when final value is 50, means 5 Volts


• OUTPUT N7:1 is just a value measured, assigned a variable N7:1 that you can use it to create more comparations or other instrucctions


• The MOST IMPORTANT value is the value in O:1.0 and the value must to be between 0 and 32.767 that means 0 and 10 Volts
