RSLogix 5000® Sample Code

7. After you enter a value into the 

Preset_Value DINT

 and toggle the 

preset contact, the message instruction presets the current count value of 

the encoder. The position value is changed to the preset value you set.

Figure 14 

Using an Explicit Message 

Configuration to Read Preset 

Encoder Value

1. Create a message data type named Read_Preset and a DINT named 

Preset_Value_Read.

IMPORTANT

Always do a 

Get

 after a 

Set

 to verify that the value was changed.
