Login-Online Change

Program changes can be made to the CPU between process cycles (scans) without upsetting the program e.g. variable resets of non-changed items. However, these changes are temporary and will not persist if the CPU is power cycled or rebooted.

To make program changes persist through a power cycle or reboot of the CPU, the changes must be written into the nonvolatile memory of the CPU.

When prompted to login to the CPU, check the Update boot application box as shown below.
