I created an array of short, 40 elements in the D area, BCD16 format.

ns=1;s=[OmronPLC]D\<BCD16[40]\>4400

If I set values in the PLC...  
D4400 = #4400  
D4439 = #4439

They are seen as expected in the vision designer tag browser.

However if I click an element, there and attempt to write...

> Error writing to D4400[1].value: Bad("Bad\_NotSupported: The requested operation is not supported.")

I created an array of short in memory tags, one can write individuals in the same manner there.  
Is this expected? Or am I missing something?

default tag provider,  
default tag group

Many OPC drivers only support writing complete arrays.

Yes indeed. I thought that might be the case, but in my initial tries I failed.

Revisiting since your response = success.
