6-1-10 Usage of Forced Address Bit

When the OMRON PLC is connected via Ethernet, there are some special bit addresses:
_FORCED_RELEASE and
Usage example:
W_FORCED, W_FORCED_RELEASE and W_RELEASE_STATUS function as follows:
W_FORCED will enforce the address bit to 0 or 1, and then retain it in the forced status.
W_FORCED_RELEASE will enforce the address bit to 0 or 1, but it releases the forced state.
W_RELEASE_STATUS will release the forced status and make no change.
Usage example:
Place two Bit Switch components and one Bit Button component with settings as follows:
Switch No.
1
2
3
Perform the test:
Operation 1:
Firstly, touch switch 1 to specify the value to "0 (forced)" and then touch switch 2 to modify the value to
"1" and it causes the bit to be released of the forced state at the same time. Also when the bit is
specified to "1 (forced)" with switch 1, touch switch 2 to modify the bit to "0" and is causes the bit to be
released of the forced state at the same time.
Operation 2:
Firstly, touch switch 1 to specify the value to "0 (forced)" and then touch switch 3, but the bit will be
remained as "0" and it causes the bit to be released of the forced state. Also when the bit is specified to
"1 (forced)", touch switch 3, but the bit will be remained as "1" and it causes the bit to be released of the
forced state.
Descriptions:
From the above results, it can be concluded that the difference between W_FORCED_RELEASE and
W_RELEASE_STATUS is: the former sets the value of address bit to 0 or 1, and then releases its
forced status, while the latter only releases the forced status of address bit without changing its value.
