RSLogix 5000 sample code Appendix B
Using an explicit message
configuration to set preset
encoder value
In this example a value is sent to the preset attribute in the encoder. The encoder
stores the preset value sent in non-volatile memory. Storing the preset value
applies the preset value to the encoder position value.
The following program fragment sends an explicit message and confirms the
message reception.
1. Create a new message data type named Preset_Message and a DINT named
Preset_Value.
ATTENTION
The preset function results in a change of position reading. This can cause
unexpected motion which could result in personal injury and damage to the
product or equipment. During preset, steps should be taken to ensure the shaft
is stationary and will remain so.
ATTENTION
In this example, a value is sent to the preset attribute in the encoder. The
encoder stores this preset value in non-volatile memory. Storing the preset
value applies the preset value to the encoder position value.
