    HMI + Forced input states problem

    Hello, We tested this and got the same results. We passed it to our R&D. In the meantime you will need to use coil of another bit as you mentioned above. Sorry for the inconvenience.
  2. In general is should not remove the application. (unless it is a really really old OS). Anyway it is required always to load the application from the U90Ladder that is compatible with the OS. In this case upload the program , update the OS and load the application again.

    Web Server...need information.

    Hello, If you wish to know that button was pressed from WebServer (not from HMI) , you can link to the actions of the web element - set bit of specific bit that the button was pressed so you will know it was pressed from the web and not from HMI. (This bit will not be linked to HMI elements). Since several clients can be connected in the same time , there is no web page change according to bit since it will change the web page to all clients. There is no automatic log off for the webserver.

    How to input password

    If the screen is blinking usually it means that the screen is reloading but since I'm not familiar with the application I cannot tell. Maybe try to use the arrows to move between displays. Anyway as mentioned try to find a contact person from the company that made this machine.

    How to input password

    Hello, First please note that Unitronics company is the PLC manufacture and as I understand KOMSAN is the company that made the machine using our PLC. In general to enter a value via the keypad is done by pressing on the key numbers. If you dont know the password then you will have to find a contact person from the company that made this machine.
  8. Hello Juan, What is the firmware version of the PLC? Does only the screen is not responding or also the ladder is not running? Does it happen also with blank application? If it is then please send a mail to support@unitronics.com
  9. Hello, 1. Is the modem connected to the USB port or RS232 port? 2. How many files are sent in one mail? BTW,we couldn't reproduce it with EHS6T modem with the two possible ports, using 1-3 400kb files in one mail.

    We want to know!

    Hello Dan, Our MQTT client is basically generic. We cannot recommend about specific broker. We tried here brokers such as RabbitMQ.
  11. Hello, Sometimes the CAN device might "wake up" only after the PLC. If you are using the "auto start" - try to uncheck it as captured and send the start using NMT command to start the CANopen slave after a delay.

  14. Hello, Please send a mail to support@unitronics.com with the application and we will test it.
  15. Hello, Regarding MODBUS RS485: Are you using MODBUS periodic? if yes then what is the interval you are sending the commands and how many commands? In general I suggest to increase the interval first to 1 second or more for example just to check if the problem relates to loading the bus more then it can handle (more than 38400 bits per second). Canopen: Can you explain in more details why do you need to change PDO1? What exactly do you want to map to PDO1? currently for TPDO1 the parameters mapped are status word and control effort.
