Hi, is it possible to read float values (temperatures) from the plc into programs like excel? does anybody has a good documentation on how to do this? best regards, markus

i got crazy with this software, why do i have to select my cpu when the command list is not limited to the commands that run on this cpu? ok, my problem: i need to compare two float values for greater_equal... what command should i use? i am using the GE Command (and several others like LT or GT for comparing two floats) is this right??

narf.... found the failure.... missing connection between Vx+ and Ix+... :)

I still get no Values.... so i decided to do some snapshots to explain my program... maybe someone can tell me my failure then... maybe some has already a block for me to use instead of mine? attached to the analog inputs are 4..20mA Signals, at the moment 7.8mA measured...

thanks, maybe i got confused from the documentation, there is written that for the FX3UC Special unit #0 is reserved :) but i do not have FX3UC, so it must be #1 like you say.... lets give it a try.... ;)

Hey, me again :) i got some time for testing my plc, everything is working fine except the analog inputs. this is how i have done it: Order of Hardware: 1x FX3U-80M, 1x FX2N-48ET-DSS, 1xFX2N-2DA, 1xFX2N-8AD, 1xFX2N-4DA How i programmed it: First on Startup send Config#1 to Module: "TOP (s)=H3333,(n1)=K2,(n2)=K0,(n3)=K1" "TOP (s)=H3333,(n1)=K2,(n2)=K1,(n3)=K1" I found in the dokumentation that the module number 0 is reseved, so i asume that my analog output is module #2 right? next in my programm, read analog values: "FROMP (n1)=K2,(n2)=K10,(n3)=K8,(d)=actual_values_internal[0] Config of actual_values_internal = Word[signed](0..7) when i compile, i get no failure, when i start monitoring, all inputs are ="0000" measured value on the cables connected to I1+/Com1 = 10mA, config of channel is "3" = 4..20mA it should be a little more right? hopefully someone will find my failure...

thanks, this helps a lot....

Hi, me again :) My Project is nearly done and i want to connect my FX3u to my GOT1000 1575 HMI. I thought that the contracter sold me the right cable, but i think i have the wrong one. Maybe someone can help me with this. Ok, i want to connect the HMI to the FX3U via the round plug where i also can connect my programming device. My 1575 only has a RS232 Connector on Board (Male) I bought a Connecting Cable GT01-C100R4-8P, but this cable only has a 9 pin male connector for the hmi side... male<-->male is not connectable ;) do i need a special addon or converter on the HMI side? i also think that the hmi is RS232, i am not sure, but the PLC is 422 right?

ok... good to know, thank you

i still didnt get the difference between data and file registers... if i take a look on the page you posted there is written: Data Registers fixed latched (battery backup) D512-D7999 File Registers latched (battery backup) D1000-D7999 for me as a green horn it looks like they are using the same memory area, and both are battery backuped... is there any difference in handling of these registers? i know that i can do something like this with data registers : ADD K10 , K20 ->Result= D514 can i do the same with file registers? like: ADD K10, K20 -> Result = D6549 ??? mybe i am to stupid for this, or i have done to much siemens... ;) sorry

Thank you very much, i didnt know that there are these functions (WR3A) i searched for them in the included documentation, but there is nothing... i finaly found now a documentation in german to this function...

Hi, first of all, sorry for my bad english... i started my first project with mitsubishi FX3U PLC at the moment, after reading many PDFs i am done with most of the things like reading analog values, setup analog inputs, pid and a wrote my own pid step controller for a solid state heating register... for the moment i ran into 1 main problem, and some minor questions... my main problem: i have 2 analog outputs, i need to have them 0-10V like they come from factory (FX2N-2DA). so far, so good... what i found is that i need to write my value for the output into bfm#16 (Bit0-Bit7) and then i need to set Bit1 of bfm#17 to start the output? first problem: my data is a word (16bits) and i limit the value to max 4000 via limitation_e block. how do i get this 16bit data into these 8bit? for you to know: i created a function block for my analog output, my value for this output is a word input of this function block. my minor questions: where is the main difference between a file register and a latched data register? i didnt find an explanation for this in my german documentation...
