IE Connection

yuvalg Posts: 8 Rating: (0)	Hello.I have 32 units of ET200S IM151-8 CPUs, and I want them all to be connected to a main 317 2pn/dp CPU with CP 343-1EX11 via IE Connection, so that the main CPU Continually send and receive data from all32 units of IM-151-8 CPUs. 1) I defined on NetPro 16 CPU connectionsand another 16 CP connections. Can I use them all with GET/PUT or BSEND/BRECV without management, or I'll have to manage a queue or some kind of server functionality? 2) What is the max byte number for GET/PUT? I thought it is 1024 but I can't transfer more then 200…? 3) Another option isto useUDP. What is the PORT number input of the functions TUSEND and TURECV ? Thanks in advanced Yuval

It establishes the S7 connections to the IM151-8 CPUs andcollects the data from your IM151-8 CPUs with the PUT and GET function blocks. So the IM151-8 CPU acts as server for S7 connections. The CPU 317-2PN/DP supports 32 instances. That means 32 PUT/GET function blocks. With PUT/GET support max. 160Byte data transfer. With BSEND/BRECV 32kByte are possible. http://support.automation.siemens.com/WW/view/en/12996906 Another possibility open communication via Industrial Ethernet with ISO-on-TCP, TCP or UDP.

yuvalg Posts: 8 Rating: (0)	Hello, Little Holmes. Not all 3172PN/DP support 32 S7 connections for IE. (There isS7 basic connection, which as I understood are for MPI/DP and not for IE). If Iuse 16 CPU + 16 CP connections, will I have to add a supervisory function? Or it will work out autonomically? Do you know how to use the PORT input for the UDP function? Thanks very much for your reply. Yuval
