6.11.4 Executional conditioned device
This function changes a device value within the specified step of a sequence program.
This enables debugging of the specified ladder block without modifying the sequence program.
*1: The executional conditioned device test is targeted for sequence programs only. (SFC programs are not supported.)
(1) Operation of the executional conditioned device test
A device value will be changed based on the registration data once after the executional conditioned device test
setting is registered.
The changed device value becomes effective in the ladder blocks of the specified step number and later.
