i agree with cross bow. i encountered that problem when i tried opening more than 3 gx devs. try checking your available memory on your PC.(RAM)

you said that you got your plc "out of storage"?you mean it is a spare?how long does your PLC in storage? the prog-e occured because you removed the battery(for over 30mins?) try clearing/formatting the plc memory.(cycle on-off after) then try to read again.

i think he's referring to PC->HMI connection. ProbPB3 is a Pro-face HMI Design tool software.

thank you guys for your replies. i'll try every single one of your suggestions. thanks regards,

I think I have to get my hands on this oscilloscope. Problem is, I don't have any experience on this kinda tools. >_<

tried that also. the card that i got from a working machine still fluctuates. and then I install the card from the fluctuating machine to the working machine and poof.it works fine. >_<

thats my another suspect. i tried replacing the Q61P PS module from a machine thats working fine, and still it is fluctuating. and i also tried replacing the noise filter used for the Q61P. still the fluctuation persist. and i dont really have any ideas left.so i turned in to you guys.hehe

yes, correct. they also have fluctuations but not the same as this one. i also tried the card in an another rack. (another set of plc in my bench). i thought the problem is with the card. Use a regulated DC power supply and monitored the the digital values. and to my surprise the card works just fine.

currently uploading it to 4shared. edit: here's the link of the video for your reference. http://www.4shared.com/video/Ui64NuGcba/MAQ02802.html regards

correct! 5.2 ~ 5.5mm i got the arithmetic but am not really sure about the values (*10 and /16). guess its the "scaling" am i correct? and yes.the HMI scales the values into -10.000 ~ 10.000mm im using GX Dev Version 8.115V and these are the to instructions. the ch were dealing with is Ch2.

i got this arithmetic on the ladder but im not sure what it meant.maybe its related on what you are asking for.(its my first time on analog-digital conversion cards,sorry) the digital value on the HMI is on "mm" -10.000 ~ 10.000mm

i have this video so you guys can have an idea in how much fluctuation it has. unfortunately the limit is 3.5mb. about the resolution the setting is high resolution mode. yes, im reading the value thru the program, and also the hmi has real time monitoring. and for the fluctuation, its playing around 0.2 to 0.3 Note: on the other machines, the value converted is stable. same configuration, same parameters, same wiring

hi guys, what factors can affect the fluctuation in analog-digital conversion? analog voltage in looks stable. (according to my tester) but the digital values that the q64ad converts has a fluctuation.

Use File registers "R" instead of Data registers "D".

Anyone here can help me about Machine analyzer function on setup 221? the resonance point value was only 58.82Hz, but the Machine resonance suppression filter 2(PB15) on mr configurator requires 100~4500Hz
