I need a bit that exist in the PLC 5 /40 like D16:20/0 but when i try to get it in cimplicity 3.22 the first problem that i have is that an error ocurrs trying to configure a point like 4-BCD type and using the same address than the pLC has. I discover that using the address N16:20/0 in the point configuration i can read the bit, but i can not write it. I will apreciate if someone can help me with this problem. It is important to know that i can't do any change in the PLC ladder logic. Thank you very much for your time.
