  1. I have tried this fix, and it gives me status 2 on the unistream PLC, that doesnt seem to fix my communication issue. However i have noticed that a couple of times i have tried communicating the IP address is completely wrong as below. The screenshot below is of that with the initial vision program i attached and not the fix you suggested
  2. I have now tested this with a V700-T20BJ with no avail of communication between a vision slave and a unistream master, so I don't know what has happened since I last did this type of communication, but I cannot get it to work at all. I have also tried unistream to unistream which is working seemlessly
  3. Hello, I am familiar with Modbus and have used it before from a vision slave PLC to a Unistream Master PLC. However, i now seem to be encountering issues when trying to communicate from one to the other. The Slave PLC is a V570-57-T20B-J with an V200-18-E1B Module and an Ethernet card added in being a V200-19-ET2. The Master PLC is a US5-B10-T24. Is there a special way I need to set up the ethernet card added into the Vision PLC as I have copied program logic used previously on already in built ethernet PLCs to get an Modbus communication error showing on the Unistream PLC, Status 3 on the Unilogic software, meaning there is communication but the commands arent set up correctly. And I cannot seem to figure out what is wrong with the Visilogic program. As seen in the attachments I have the code for visilogic with MI0 Flow Test value linked to the screen to be able to manually change the number to see it on the unilogic program. On the Unilogic program I am reading address 0. All IP addresses and ID numbers etc all are aligned as they should be. Any advice would be greatly appriciated.
  4. I did think of this, obviously a much easier solution and guaranteed sucess, however the supply from unitronics on parts is obscene at the moment so getting hold of another one of these for however many projects we would use 2 instead of 1 might be a great issue. Hence the reason for trying to work out if i can reprogram it.
  5. What I am trying first from the MODBUS Register list is trying to read the values of Baud Rate and Modbus address, as from the table it shows this should be 1 and 3 respectively, however currently reading these addresses I am getting 0. So I feel if I understand the issue as to why i am not able to see these values on the HMI screen I can then work on setting the parity bit with the steps you've already suggested. Each Tag on the unilogic program below for the 3 addresses shown are UINT16. Any help again would be greatly appreciated.
  6. This has not worked, unless i am doing it incorrectly I have the red wire/ green wire connected to +24V and black wire connected to 0V The Yellow and white are connected to the RS485 COM module on the back of the unistream I power on the plug socket to power the PLC and sensor I write the parity bit to 1 in the program via a button on the HMI. I disconnect the green wire - (and see values on the screen which I shouldn't if I've changed the parity of the sensor) I then download a new program to the PLC with the changed parity bit of the COM module I then turn off the power and reconnect. what is it I am doing wrong? I am very confused as to why it is not changing Thanks again for your help
  7. Hi thanks for the reply, I really struggle with the wording of the manual as posted. So I need to: 1) power on the sensor with the green wire connected 2) Write the parity bit to 1 from unilogic to the sensor 3) disconnect the green wire 4) Power off then on sensor 5) Connect the sensor to unistream again by changing the parity bit on unilogic to match the sensor Is this correct?
  8. I have already tried changing this through Unilogic program, with the wording on page 5, i am unsure what to do with the wiring? Do I need to use the green one? I have tried using this on the program, however when i have green connected I see no values on the screen from the sensor, but when it is not connected, I see values but then don't know if the sensor is in its setting mode.
  9. Thanks for the reply, do you have any links to online software you have used?
  10. I have a US5-B10-RA28 with a UAC-CX-01RS4 card fitted onto the back. I have 2 sensors needing to be wired to fit the PLC Program, however the 2 sensors have a different default parity value, meaning they don't work together and only work when I set the 01RS4 card in unilogic program to either Parity = None for one sensor and Parity = Even for the other sensor. This however is not suitable for my application as I constantly have to redownload the project to the PLC changing the parity value for the module to get one sensor running. So my question/ help needed is how can I change the Parity value of the sensor below, and is there a way of doing this through unilogic?

  11. Hello, I have this SM35-J-RA22 PLC and it has this error appearing on it, it was working before it got sent off with a program to a customer and then when switching on for the first time their end, this screen occurred. I've tried having a look through Forums but can't seem to find anything on how to fix this issue on a Samba> Can anyone help? Thanks
  12. Thanks for the reply, we also tried this solution of a software switch to be able to utilise both inputs, however we have now gone through about 3 V350s with all the Analog inputs not working, we have bought a S1SL-1AI-1C Signal conditioner we have tested it wired up with a signal generator to the PLC but not yet to the complete system with the actual 2 wire sensor, but am unsure yet to if this is the right product/ will work? We have wired the PLC for the customer so I doubt the issue is them shorting the 4-20mA line with +24V, and for it to happen now to 5 analog inputs is baffling, so we shall try the signal conditioner we bought and see if that resolves the issue, if not, we will have to try your other solution! Thanks again
  13. I have a job using a V350-J-RA22 and use one of the analog inputs from a 2 wire sensor, the sensor has a 24v wire powering it and then a wire to the PLC sending 4-20mA. However a recurring issue is happening which we cannot fault find the reason why, where the analog inputs are blowing/ stop working. Our only thought is to do with the datasheet as highlighted where it says max input rating 1.1V, and were sending into the PLC around 6V or so. So if this is the issue how do I go about stopping this from happening in future/ why is it not seeming to be an issue when I've done a similar program with sensor on a unistream. And if this is not the issue, what could be causing the analog inputs to stop working from the 2 wire sensor we have?
  14. Hello, I am relatively new to Unilogic and completely new to CANBUS, and I have a project that requires 2 encoders a single turn and a multi turn encoder. My struggle is with the software and how to generate the position values for the encoder onto the PLC, I have followed all the help guides etc and have uploaded the manufacturer EDS Files for the encoders, but I currently seem unable to get a reading onto the PLC HMI. And I cannot for the life of me figure out what I'm missing or have done wrong. Can anyone help or have any tutorial videos for if I'm missing anything in the Ladder logic or in the CANopen set up. Thanks
