I am using CPU 315_2PN/DP. with that i am using CP- 341 RS 232c 6es7-341-1ah02-0ae0

I am using s7 1200 cpu and CM 1241 Rs 232 for sending data to CP - 341

i am using 3964 R protocol for communication. 

I have selected Baud rate 9600, Parity Even, stop bit 1, data bit 8, prority low.

I have loaded this configuration in the S7 300 system. I loaded rs232 program to S7 1200 Cm Module

After that connected the RS 232 cable to device. without loading any program TX and Rx started bilking on cp341. with no fault indication. That was bit confusing.

Then In program i have used following blocks

OB1,  main program

FB7, P_REC_RK,

DB1, INSTANCE DATA BLOCK FOR FB7

DB10 A SHARED DB FOR RECEIVING THE DATA

SFB52, SFB53

I HAVE CALLED FB7 DIRECTLY IN OB1.

AFTER DOWNLOADING THE PROGRAM I AM NOT GETTING ANY ERRORS IN FB7 BLOCK.

BUT I AM NOT ABLE TO RECEIVE THE DATA IN db10.

WHEN I CHECKED THE DIAGNOSTICS OF THE CP CARD ONLINE.

ITS SHOWS ME ERROR.

ERROR IN CONNECTION BUILD UP Fxc8:0802.

I TRIED TO SORT IT OUT BUT I AM NOT GETING SOLUTION TO THAT.

Warm regards
