Maximum Update Rate of the [c]FP-DIO-550 The data sheet for the other Digital Output FieldPoint modules lists that the all channel update rate is 20 kHz, and that the update rate for the Digital Input modules is 1 kHz. What is the maximum update rate for the [c]FP-DIO-550, Digital Input/Output Module? URL: http://digital.ni.com/public.nsf/allkb/22FF3A4176EF96FE862570FF00827202

[c]FP-DIO-550 Will Not Power On I have a [c]FP-DIO-550 module in my FieldPoint system. I notice that when I apply power to the system, all modules, including the [c]FP-DIO-550, blink momentarily, but the [c]FP-DIO-550 always powers off afterwards. I tried to add the module manually under Remote Systems in MAX, but because I URL: http://digital.ni.com/public.nsf/allkb/D0D063BE53440D12862570DC006BEA7C

How Can I Connect AC Signals to my [c]FP-DI-330? The [c]FP-DI-330 user manual rates the input range of the module for AC signals up to 240 VAC. How can I connect these signals and how do they work? URL: http://digital.ni.com/public.nsf/allkb/270E85C95D808D3F8625702A00766844

How Do I Use the Index Channel on My [c]FP-QUAD-510? I have an encoder that outputs a pulse each time it completes a revolution. How can I connect this signal to my [c]FP-QUAD-510 properly? URL: http://digital.ni.com/public.nsf/allkb/F9ECF4712AE59F6386256FF50069FCF9

Letter of Volatility for Some FieldPoint Modules I need official National Instruments confirmation that sensitive data passing through my static FieldPoint module will be erased when the device loses power. Where can I find it? URL: http://digital.ni.com/public.nsf/allkb/22587A167259EEBD86256F8C00105B50

Quadrature Encoder Counting By Two I have a quadrature encoder connected to my counter and it seems to be counting by two with every tick. In addition, at certain values the count register will appear to respond out of order as if the count back-tracks for a couple of ticks.

ロータリエンコーダの各ティックに対してカウンタが2つずつカウントする問題について。 現在カウンタに接続されているロータリエンコーダの各動作でカウンタのカウント値が２ずつ変化しています。また、時々、エンコーダが回っているにもかかわらずカウント値が変化しません。この原因は何でしょうか？ URL: http://digital.ni.com/public.nsf/allkb/76DFC69178E8FAA1862570BC000E511C

Why Doesn't the Channel LED on my (c)FP-PG-522 Light Up When I Output a Pulse Train? I created a pulse train to output from my (c)FP-PG-522 in LabVIEW. I ran the program with no errors, but my Channel LED on the PG module does not light up. URL: http://digital.ni.com/public.nsf/allkb/FDB554CD51860AEE86256F32007D9E9E

My FP-QUAD-510 Will Not Count Why does my FP-QUAD-510 not count even though it is connected to the terminal base? URL: http://digital.ni.com/public.nsf/allkb/38142479A794491886256F20006AEF84

Displaying Warning Message in LabVIEW/MAX for Short Curcuit Protection of a [c]FP-DO-410 Will I get an error message in LabVIEW/MAX(Measurement and Automation Explorer) when a channel(s) in my [c]FP-DO-410 is short circuited?
