PLC Controller Firmware Upgrade

When you buy the plc CPU for the first time, you need to upgrade to the appropriate version for your program.
If your program is written with version 30, you need to upgrade your CPU to version 30. CPUs come as version 1 by default. You can easily upgrade the CPUs of PLCs with Firmware upgrade as follows.
Let’s see how it works with an example.

You can choose to upgrade controller firmware by using one of these tools:
• ControlFLASH™ software that is packaged with the Studio 5000® environment
• AutoFlash feature of the Logix Designer application
