Nothing Clear Can describe me

If you want to force an IO, you have to connect that IO with a variable of datatype 'BOOLIO' for boolean and for analog is 'REALIO'.
after that you will get some additional bits under those variables.
you can force a IO variable by ".Force" bit under those variables.
and so that you can also force it from hmi through connecting the".Force" Bit to a button.

Try this, if you have any difficulty then revert...

All the best.

Regards

Sorry I didn't get you.

Can you attach the screen shot so that I can understand what is happening?

Suppose, I forced a Input when it require.
After sometime I feel that I don't need it.and send a 0 via .value, which make variable value false but in forced field still have (x).

ok
When you set the value of .force to True then you can force the .value to True or false.

If you want to release the force then you have to reset the value of .Force to false and then only the (x) cross sign will automatically disappear from the channel.

Process Graphics (VB6 or PG2) can be made to write to any adressable OPC item; try the "Checkbox" (DI) and "Input Field" (AI) controls.

Input IO need to be "forced" to allow HMI to set a value. Forcing is a bit abnormal and will highlight warnings in hardware tree of CBM - so for an item that need to be writeable at all the time I suggest configuring a SoftPoint or General Property instead.
