Dear Experts, I programmed by following CP-ptp samples by using FB2, FB3 (P_SEND, P_RCV). but i got a message "unable to copy FB2, FB3" while downloading and CPU SF light coming and goes to stop. But i can simulate with PLC SIM no problem at all. So kindly advise me the way to solve my problems. I am using CP340 in ASCII mode to test hyperterminal. Thanks in advance!

Hello phyoemaung What is the part number of your CPU, how old is it? Gut feeling tells me it is an ancientone which does NOT have SFB52/53 in it (these are called inside FB2&FB3) and that's why it does not allow the download. The easiest way to to findout which SFC's and SFB's your CPU support please isthis: 1.) Connect to it, select the CPU or blocks folder andgo to Module information (CTRL+D) 2.) Go to the "Performance Data" tab and see what System Funtions are in your CPU. If SFB52/53 areNOT listed, you can NOT use FB2&FB3 (P_SEND, P_RCV) and instead need to use "P_SEND_OLD" and "P_RCV_OLD" (these use SFC58/59 instead and canbe found in the same CP340library as FB2/3). I hope this helps |
