	Release an easy way to program the fast FRNET remote I/O modules

	FRNET is a fast remote I/O system. The wincon-8xx7 and the iPAC-8447 / 8877 (will be available) support it. Please visit the following web site for more information. http://www.icpdas.com/faq/isagraf.htm > 082 or www.icpdas.com > FAQ > Software > ISaGRAF > 082

	The I/O scan time of FRNET bus is about 3 ms . (This depends on your program’s PLC scan time, for ex, if the ISaGRAF PLC program scan time is about 9 ms, then the scan time for all FRNET I/O channels will be 9 ms, not 3 ms. The following table shows the approximate PLC scan time of an ISaGRAF project which runs only FRNET setup code (without other codes) . It is more than 20 times faster compared with the I-7000 and I-87K RS-485 digital remote I/O.

	One I-8172 FRNET master card can connect max. 256-ch D/I plus 256-ch D/O .
