  1. The resolution shouldn't be a problem, did you configure the input to be 0-10V? the resolution will only affect your measurement by making it more or less precise depending on the case. Try measuring the output of the Oxygen transducer, since its 0-10V you can just put the probes on the Analog Module.
  2. I contacted support and Guy Sela helped us, he explained this: We were confused with the addressing of the directions, it seems that the read only and the readwrite are stored on the same byte regardless of the type. I hope somebody else find this helpfull too.
  3. When I create an HMI Slave in unilogic the unistream doesn't generates a Modbus address relation for the tags we are creating, it just shows address 1 or address 2, what I want to know, is the relationship between these and the 0x from Modbus, my issue is that with my HMI I can read registers and read 1x coils from my master HMI, but when I try to write (I programmed a button on my hmi to start a motor) the signal never arrives to the PLC. List of Master HMI tags: 1X 1: XS-MR102 1X 2: XS-MR101 1X 3:PRUEBA OUT 0X 1: START BANDA 0X 2: STOP BANDA 0X 3: CERO 0X 4: PRUEBA IN List of Slave Unistream tags: COIL 1 XS-MR102 ADDRESS 0 READ ONLY (XS-MR102) COIL 2 XS-MR101 ADDRESS 1 READ ONLY (XS-MR101) COIL 3 START BANDA ADDRESS 2 READ/WRITE (START BANDA) COIL 4 STOP BANDA ADDRESS 3 READ/WRITE (STOP BANDA) COIL 5 HS-BOT ADDRESS 4 READ/WRITE (CERO) COIL 6 PRUEBA HMI ADDRESS 5 READ/WRITE (PRUEBA IN) COIL 7 HMI SALIDA ADDRESS 6 READ ONLY (PRUEBA OUT)
  4. We have an issue regarding the Modbus TCP/IP communication with a third party HMI(Weintek), the read only bits can be read but I can't seem to write data on the PLC, how can I match the address that unilogic uses to the Modbus Standard( 0x 1, 0x 2, 1X 1 and so on) does this address matches exactly to that standard, say, If we configure a Coil to address 1 read only does this translate to 0X 1?, and if a second coil is configured as address 2 read/write does this means 1X 1? or 1x 2?. As I stated before, Our master HMI can read the coils configured as read only, we can even read and write registers, but we haven't been able to write to the PLC.
  5. Greettings, is there a way to export the csv file including the date in the file name? Currently I have the name "Refinacion" as the exported file name, I think it is overwritting this file every time it exports.
  6. Greettings, have there been any development on the construction of a simulator to test new programs or modifications before uploading them to the PLC?
  7. No, I haven't been able to send any email, even without any attachment(only text email), it stills goes to status -4. I'm using Unilogic 1.15. I tried first using a Gmail and then using the Corporative Email, non of them worked and they had the same behaviour. If the issue was an email configuration wouldn't the status be other than attachment error? Also, is there a way in this version to visualize the data tables in the web server?
  8. Hi, I'm getting status 4 while trying to send the alarm log and the data tables via email, I think the issue might be related to the File Name, is this the name that I want to be reflected on the output file(the one to be sent via email) or is this an inside file name?, also I tried sending the Data Sampler but I didn't knew what the folder name was, the folder name for my data table and the alarm log are set automatically
  9. Hi, I Don't have the usb driver in my pc to manually install it and whenI try to download it I get "Share has been disabled", is there another place where I can download it? I'm using Windows 8 SO.
  10. I just succeded in running the PID process, it took more than 15 minutes. The parameters are these, sample time=100, P=500, I=145,D=144. the current Process value is slightly above my set point. Thanks for the help.
  11. It is a consistency control of pulp made from recicled paper, I have a consistency transmitter that trasmit the % of solids in the water(thats my PV, I configured it to have a range of 200 to 600 in the analog In, this is because the range of my transmitter is 2% to 6% of solids in the water) it is reading the signal from the trasmitter perfectly, I control the consistency in this stage using a control valve using an electronic positioner(thats my output, the CV), it is an reverse relationship, if I open the valve the consistency willl drop down, this is because when the valve opens it injects water into the system thus reducing the relationship between paper and water. According to the process engineer, the dead time(not sure if this is the correct translation, I know this as "tiempo muerto") is really low, he states that when you open the valve the consistency drops down really quickly. we have the SP set to 350 and the process value is usually around 320, but when I run the PID it just goes 100% open, I have the reverse action bit set to 0.
  12. I'm running the PID for an analog output (4-20mA I have them configured as 0 to 1000 in the output range, I tried manually operating the value by storing an int value from 0 to 1000 in the selected output and it works fine, 250 means 25% 500 50% and so on) , I deenergized the autotune block, because I thought it was frozen, should I just reenergize it and wait?
  13. Hi, I got the PID documentation from another post in this forum, I'm getting the STATUS value of 2 in my PID config Struct, what does it mean? also How do I know if it is performing the autotune procedure?, My coding is quite similar from the video tutorial for PID, but when I try to run the PID autotune it stays there forever (I asumme this because the Autotune done bit never turns 1), and I see no action in my control value, it simply stays in 100% of the output value. From the documentation I think the status for normal operation is 4.
  14. We solved the issue, we opened the analog I/O, it has 3 electronic boards, in the bottom one, next to the 24V in, it has a small component, it says F100, we tested continuity and as we expected from our previous conversation there was none, we blown the fuse when we made the short circuit, we tried with one first, we bypassed that fuse using a small copper wire, and when we turned the PLC on, it made the boot sequence correctly and the Status Led turned green, I checked the I/O status using Unilogic and it showed 0x00. thanks for the support it ultimately led us to figure out that it was a hardware issue(now that I think about it made this is in the wrong forum considering this is the software one haha). We are going to protect them placing fuses in the 24V in. I took pictures to upload them here, in case someone else has a similar fault, but I don't know how to upload these into the forum.
  15. The two power supplies are 240W DRP-240 24 V 10 A, I even tried connecting each of the I/O directly from each of the power supplies directly and I'm still getting the same behavior, I don't have the data from the current that is currently being supplied by each one, I can run that test in half an hour using an amperimeter, but It has to be less than 10A, they are only connected to 16 I/O Modules using a AUG-XKP125 and a Unistream USP-156-B10 PLC. I don't think the short circuit is still present since the rest of the system is running smoothly. It seems to me that there a low chances that the 4 of them burned out at the same time and the rest of the I/O didn't, what do you think?, although unlikely it is a possible scenario. Are the analog less protected than the digital and the High speed I/O?
