OP17 $505 (Transfer Locked)

Dear Sirs,

I'm using an OP17 and a CPU 224 to work with recipesinmy application.

But I'm having problems to transferData Records using Standart Transfer Screen (Recipe Directory> Transfer) . I filled out the "Source" with the Data Recorddesired (01, for example), the "Destination" with 00 (OP -> PLC) and when I try to confirm(accept ->ENTER) the error $505 (Transfer Locked) appears.

My memory Interface Area is VW70 (length 16 words) andI've already tried the follow code in main program of PLC (MicroWin):

LDV73.3
SV73.2,1
RV73.0,1

AND

LDV71.3
=V71.0
=V71.2

However, none of them worked. I have read the "Manual HMI communications" and "OP17 user guide", but the informations there are poor. So, pleaseI need urgently your help. What is the correct form to do it ??


Best Regards,

Berg
