OP77B list is $490 Don't know about the OP77A OP73 list is $260 The OP73 can be programmed with WinCC Flex Micro once the panel is released but the release has been delayed. And it will only talk to the S7-200 from what I can find out. WinCC flex Compact List $150 can program both the OP73 & 77. The OP77 can communicate to S7-2/3/400s. And the panel is released for sale.

Now these products are no longer produced by Siemens. You can buy used ones in the second-hand market, or buy related accessories for repair and replacement.
