Optimizing RSLogix 500 Backups with a Dedicated RSLinx Driver

Improve DeviceLink Backup Speed by Scoping Your RSLinx Driver to RSLogix 500 PLCs Only

Overview

When Copia DeviceLink performs backups of RSLogix 500 programs, it scans the communication path configured in RSLinx Classic to discover and connect to devices. If that path contains a large number of devices, DeviceLink carries unnecessary overhead during each backup job, which can slow down collection times.

A simple best practice to improve backup speed is to create a dedicated RSLinx driver that contains only the RSLogix 500 PLCs you want to back up. This keeps the scope of each DeviceLink job focused and reduces the number of devices being polled.

RSLinx and DeviceLink

Copia DeviceLink relies on RSLinx Classic for device connectivity when backing up Rockwell processors. The communication path defined in RSLinx determines which devices DeviceLink can see and interact with during a job. If that path includes devices unrelated to your backup target, DeviceLink still has to work through them, adding time and load to each run.

Solution

To create a dedicated RSLinx driver for your RSLogix 500 PLCs, follow the steps below:

  1. Open RSLinx Classic and go to Communications > Configure Drivers.
  2. Add a new driver appropriate for your network (e.g., EtherNet/IP).
  3. Once the driver is created, add the IP addresses of each RSLogix 500 PLC you want to include.
  4. Verify that no other device types are included in this driver.
  5. In Copia DeviceLink, open the configuration for your RSLogix 500 devices and update the communication path to reference the newly created driver.

With the path scoped to only the relevant PLCs, DeviceLink jobs will run faster and with less unnecessary network traffic.
