[singleperson]

Dear All members,

Does anyone have experience with Microwin & Step 7.
Please kindly help me.
Now I use Windows7 - 64bit.
I installed Microwin SP9 & Step 7 v5.5 SR2.
I can not connect with PLC S7-200 use cable RS485.
I installed all software on Win XP SP3 & connected successfully.

On my opinion, PG interface is not compliant with Windows 7 64bit. because I see PG interface, which installed on my laptop, display 32bit.
Does Anyone have the same problem, please help me. Please help me.
Thank for for your helps & have a good weekend!!!
