Hi all,

Does anyone have experince of cummunication with a Siemens S5-115U 944 using 3964R over the second serial interface ?

I have a Horner TIU 110 configured with the 3964R protocal but am unsure regarding the necessary FBs to call in the PLC and the parameters
required.

Thanks

Wayne

 

If you are working with a Siemens S5-115U and pobible using a CP-525 or CP-524 for comunications, you have to call ( in OB1 for instance)the next functions:

+ FB244 (SEND)
+ FB245 (RECEIVE)

Both for handling information and with these parameters:

+ SSNR : Inteface number
+ A-NR : Quest Number (0 by default)
+ ANWZ : Indication word
+ PAFE : Error byte

The other parameters are irrelevant.
Also, you have to call into OB21 and OB22 this function:

+ FB249 (SYNCHRON): to sychronize.

wich paarameters are:

+ SSNR : Interface Number
+ BLGR : Data-block size
+ PAFE : Error byte.

I hope this information would help you.

Dear Friend

I have worked for communication on AS511. I prepared the software which can same thing that you want. Why you are not using AS511. Though I
have not worked on 396R I can do it. Why you are interested in 396R? because using AS511 u can communicate without CP card and you can
directly save price of CP card.
