Hello LalitN I wonder if there is perhaps another way to solve your problem. You say that "Iam using the profinet card installed in my PC 'as a master', so that i can develop my own SCADA and could communicate to IM 151-8 PN/DP CPU." Any off the shelf available SCADA would NOT require you to configure it as a PN I/O Controllernorto link the PLC as an I/O Device to it (you'd be way to limited with this type of communication who's application aim lies in fast cyclic distributed I/O data transfer). Instead a SCADA system would - in the case of a Siemens S7 PLC -utilise Siemens propietary S7 communications to read/write data from/to an S7PLC. Some thrid party SCADA system have developed their own direct S7 driver for this, others use either Simatic Net Softnet as the "middleware" orOPC. If your aim is indeed to have your own custom developed SCADA system communicating with an S7 PLC, I suggest you reconsideryour choice of Profinet I/O Controller/Devicelink and opt an OPC Server /Client solution instead. One more than suitable OPC Server would be Siemens SOFTNET-IE S7 (see HERE for more), "all" that's left to do for you is to develop the OPC Client for your SCADA. Food for thought anyhow and I hope it helps |
