The I/O scan time of FRNET bus is about 3 ms . (This depends on your programˇ¦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. |
