CHAPTER 3 CPU MODULE FUNCTIONS

3.19 Executional Conditioned Device Test
(c) Online change to the CPU module where the executional conditioned device test
setting has been registered
For the online module change (ladder): if any executional conditioned device test setting has been registered in
the ladder block that is to be changed online, the CPU module disables the corresponding setting.
Step numbers of registrations 1 to 3 are specified in the executional conditioned device test settings. When
the ladder block including the registration 2 is changed online, the registration 2 is disabled. Since the
registrations 1 and 3 are not included in the change target program, they are not disabled.
When multiple ladder blocks are to be changed online, ladder blocks between the change target ladder
blocks are included in the change target. In the following example, registrations 1 to 3 are all disabled.
When a ladder block is to be added online, the executional conditioned device test setting included in the
ladder block followed after the added ladder block is disabled.
For the online change (files), all executional conditioned device test settings registered to the target program
are disabled.
