Trying to write a bit to OMROM PLC using FINS Write node.  
I have E0\_22228.2 set as my address.  
I am passing a payload of 1 and 0, 5 seconds apart, i have even formatted them to be arrays i.e. [1] and [0].

the node returns complete and posts successful output to debug but bit in PLC state doesn't change.

Do I need to use the buffer creator to just write 1 boolean value to 1 bit?

Bit write is not supported. What's happening is when you write 1 to `E0_22228.2` it's writing 0x0001 to `E0_22228` meaning bit 2 is getting set to 0

I have a beta version you can test.

It is not yet published as I am waiting feedback.

Are you interested in running a beta version?

I'd be happy to test it.  
In the meantime I'm going to use a H bit instead
