Internet PLC Forum

Thanks, now it works like a charm.  

Found a free software on the web called Advanced Hmi (some kind of software HMI)  which I try use together with my nano-10 trough Modbus/TCP. I can display and write values (holding register) back and forth but I can't control any outputs or internal relays from the software. Toggle a relay in the plc and make a lamp symbol blink on the screen works fine but I can't use a switch symbol to toggle a relay or output in the plc.  Asked Advanced Hmi support about my problem and they did a successful test with a slave simulator and the address 00258 (nano output 2 if I'm not mistaken). Any suggestions about what I doing wrong?  

I can't display a string returned from the The NANO-10 plc on the virtual LCD screen. It shows up on the online-monitor LCD but not on the web page display. I want to check that a text file transfer is complete by getting  a <OK> from the plc.

I also have some trouble understanding how the timer functions work.  I use the timerPV command in a function and  when the timer reaches 0 the timerbit goes high. How do I reset the timerbit? I tried using the settimerSV and clrbit command but it won't work.

Now it's working, Thanks. Another question. Is it possible to transfer Time and Date variables into a DM or sting. So you can use it like a timestampe.

Hi,

I Want the nano-10 to create a text file containg data from DM1 to DM50.

I tried using the code below but no file is created in the fileservice folder. I have a direct ethernet port to port
connection between the pc and plc. What could I be missing?


PRINT #4 "<RemoteFS 192.168.1.2:9080>"   // have also tried localhost IP: 127.0.0.1:9080
PRINT #4 "<WRITE TestFile.txt>"
FOR I=1 To 50
PRINT #4 DM;" ";
NEXT
PRINT #4
PRINT #4 "</RemoteFS>"

To bad that customization is not supported. This stuff isn't easy for a average joe like me. I'm not quite sure what I did exactly when I added more boxes. I changed one
thing in the drawrelay() function (as you pointed out in your replay). Have been fiddeling with the doclick() function aswell but got stuck.




function drawRelay(){
  var el
  var ioname;      // replace space with "&nbsp;"
  var value = RELAY[9]  // Internal Relay #129 to 140
  for (i=0;i<14;i++) { //-------------------------I changed this line
    el = document.getElementById("IO"+(i+1))
    if (el==null) {
      ioname=""
      for (j=0;j<IOname.length;j++) {
           ch=IOname.charAt(j)
           if (ch==' ') ioname += "&nbsp;"
           else ioname += ch
      }



function doClick(el) {
  var xmlhttpClick= createXMLhttp()
  clickBusy =1
  clearInterval(intervalID);
  if ((el.id).substring(0,2)=="IO") {  
    var rly = RELAY[9]

    var pos = el.id.substring(2)-1
    rly ^= bitMask[pos]          // toggles bit
    cmd="HOSTLINK/WR10"+d2h(rly)+timestamp()
    clearInterval(intervalID);
    xmlhttpClick.open("GET",cmd,true);
    try {
      xmlhttpClick.onreadystatechange=function() {
       if (xmlhttpClick.readyState==4) {
         checkSvrResp(xmlhttpClick,"doClick")
         clickBusy=0        
         doUpdate()
         getRelay()


Is Relay[9] the same as relay channel 10, as in cmd="HOSTLINK/WR10"+d2h(rly)+timestamp()

Repeat code? Please explain.

Ok, storing files in the nano-10 is not an option. I would like to use the nano?s web pages  as a simple form of Hmi. Just connect the plc directly to a pc?s Ethernet port.  No internet access.  Can I store graphics  in some folder on the pc and use with the web pages.
