No error occurs even when the instruction that is different from the I/O driver settings is used.
For example, I/O driver setting CH1: pulse
when using PWMX (CH1) in the above case
Even in the above case, the pulse parameter will be changed due to the I/O driver setting when the PWMX instruction is executed. The same behavior will take place regardless of PWMX or not.
The special I/O driver instruction cannot be edited online.
Do not coexist #L system variable and I/O driver instruction for controlling the same CH.
Pay particular attention when you use the I/O driver instruction in the existing project. Even in the above case, no error occurs.
When the display unit is turned off while changing or reading the parameter, the parameter change or read will be continued after restarting the display unit. At this time, when the I/O driver instruction is executed, it is determined that the process has been already started, and an error is generated.
When an error has occurred, the instruction is not enabled. If an error has occurred after enabling the instruction, the instruction will be disabled when the error is confirmed.
For the same CH, make sure to execute the next instruction after confirming that the current instruction is enabled. The instruction will be executed even if you do not confirm the enabled condition, but it may not function properly.
For example, operating PLSX and PLS instructions with pulse output
In the above case, the pulse output may not be performed according to the settings that have been changed with the PLSX instruction
When you use an instruction among from PBC-PBR instructions, the following will take place.
When PBC is ON (enabled)
Instruction will operate according to its specification.
When PBC is OFF (disabled)
The instruction will not operate.
However, once the instruction has started to operate, it will operate regardless of the ON/OFF state of the PBC.
The instruction operates when the I/O setting is enabled.
