POINT
1. When setting a word device with a different value format, a device is regarded
as the same device.
[Example]
When a word device is set in the following order, "D100 (16 bit integer)", and
then "D100 (Real number (single precision))", "D100 (Real number (single
precision))" is registered.
2. When setting a device with a different modification method (such as a bit-
specified word device, digit-specified bit device or index-modified device), a
device is regarded as a different device.
[Example]
When a word device is set in the following order, "D100.F", and then "D100Z0
(Real number (single precision)), both devices are registered.
2) Step specification for executional conditioned device test registration
Any step number (0 to step number for the END instruction) in a sequence
program can be specified.
POINT
Be sure to specify the start step of each instruction.
3) Execution timing specification
Timing of changing a device value can be specified. A device value can be
changed either before or after an instruction of the specified step is executed.
Figure 6.43 shows the module operation based on the execution timing.
