dear all, I have a possible order with a big problem, I hope that you can help me. I have to integrate a system: Rx3iCPU with SRTP protocol in a system that already exist. The existing system has: PLC: S7-400 siemens Server: SUN Enterprise 480 in cluster redundant configuration OP: Solaris 8 DB: Oracle The SCADA software is a proprietary application developed from customer acquiring directly the siemens PLC through TCP/IP network. The customer has developed in C lenguage the communication driver for siemens PLC. Is it possible to provide to customer the communication driver for SUN machine on SRTP protocol? If no, is it possible to provide to the customer the necessary tools to develop the communication driver by himself Thanks Ale
