Niranjan Prasad Posts: 691 Rating: (37)	Dear Experts I am facing problem in adapting communication between an S5 CPU and OP 177B PN/DP The Problem is: I have developed the WinCC Flexible project and defined the Communication as "Simatic S5 DP" But I got Trouble Here , as OP177B doesn't have RS 232 Com Port I don't Know How to make the Connections between them ( S5 CPU and OP177B)

Connection via AS511 (the S5 programming port) are unfortunately no longer supported (they were possible withthe previous generation of Panels). So Profibus DP is the way to go and your Panel will have a DP port (RS485) on it and you hopefully already have an IM308C or CP5431 in your S5 (or have a 95U with onboard DP Master port). I'd go for the IM308C (if you have a choice) which imho is easier to use for this purpose. I hope this helps (but have a feeling it is not the answer you wanted) Attachment HMI-S5 connection options (catalogue ST80-2009)S.jpg (659 Downloads)

You have to connect to a Profibus DP port on the S5 side ( Pl see details provided by fritz ) Also I do not understand what cable you want from 9 pin to 15 pin. Maybe if you define your configuration clearly - S5 PLC Hardware details others can help you. Regards Navnag

Niranjan Prasad Posts: 691 Rating: (37)	I am using OP177 B PN/DP But for Testing on AS511 Connection , I am using OP77B as OP177B doesn't have RS232 port in it ; it has RS485 Port only I am Using s5 115U CPU and WinCC Flexible for configuring the HMI

As I said in my previous post, you would need a V.24 ( RS232) <-> TTY convertor ( Same as used for S5 programming ) to link up the two. Good Luck Navnag

I'm afraid you need to give up on this one and bite the bullet and either go Profibus DP (as advised ealier)OR choose a Panel that still supports AS511 (there aren't many left though). Nonetheless, this link will give you all the info about connection cables: What connecting cables are there for connections between the operator panels and the different controllers

However WinCCFlexible ( I have 2007 version ) allows configuration of IF1A as AS511 for S5 Communication. Though I must admit, I have never really tried it in any project. I have used MP-277 frequently with S5 on AS511 without any problems. Dear Niranjan - Would like to hear from you on yoru experience Navnag
