Operation during online change
This section describes the operation performed during the online change of the CPU module to which the device test with
execution conditions is registered.
■Online change (ladder block) (without adding or deleting instruction)
If a part to be changed by the online change (ladder block) includes registrations of the device test with execution conditions,
such registrations are disabled.
When the Registrations 1 to 3 of the device test with execution conditions are registered for the steps as shown below, the
Registration 2 is disabled upon the execution of the online change (ladder block). The Registrations 1 and 3 are not disabled
because the steps to which they are registered are not included in the part to be changed.
