5.3.4. loopbackExampleTagWriteSynced.L5K
This example program demonstrates an RSLogix 5000 loopback PLC program using the Write-to-Tag-Synced
receive method. This program configures a DeviceMaster UP 1-port at startup and then loops data through
the loopback plug on the serial port. The Com1_RxData tag transmits and receives the data, increments the
sequence numbers, and sends the consumed receive sequence number to the DeviceMaster UP after each
received data packet.
You can configure and run the loopbackExampleTagWriteSynced.L5K program through RSLogix 5000. For
additional information on the RSLogix 5000, see
5.3.7. RSLogix 5000 Screen Examples
1.
Attach a loopback plug to the serial port. (If necessary, see the
DeviceMaster UP Hardware Installation
2.
Open RSLogix 5000.
3.
Import the loopbackExampleTagWriteSynced.L5K file.
Note: If you have problems loading the PLC program example, see
