How can I speed up the data throughput of my DSData application?
• If using serial communication, then use fastest possible baud (bps). • Use an ECOM instead of serial connection . . . much faster. • Creating Subtopics in DSData will allow you to assign different update intervals, thus enabling you to prioritize, thus increasing throughput on higher priority Items. • Win95, Win98, WinME operating systems are terribly slow; therefore use WinNT, Win2K or WinXP, these are sometimes 10x faster. • If using ECOM, give it an isolated network if possible, as network traffic can effect data through-put. • Use fastest PC possible. • If using the Ethernet SDK, use asynchronous reads as opposed to synchronous reads in your application code. • Each write is handled individually, therefore if writing to individual bits it is better to group them together and write once to the imaged V-memory of the PLC instead of each bit having its own write. For example, if using DL260 CPU, instead of writing to C0, C1, C2 individually, set these bits in a word and write the si
