    Hi Franz,
    There is no problem using Terminal 4 to set the output frequency. Then configure the AU of another  terminal RL.      When we want to work with the current input, we supply + 24V(terminal PC) to the terminal that we have configured as an AU (RL in my example ). It is necessary to use STF and STR terminals for START forward / START reverse.

    Hello all! I have a FX1N-60MR. I need to display the contents of their data registers to the SCADA system. If you look at the product catalog, there are a few solutions either install into the slot of the additional equipment interface adapter FX1N-CNV-BD connect the communications adapter FX2NC-ENET-ADP, but this raises the question - what Protocol is used?, either install in the slot of the additional equipment interface adapter FX1N-CNV-BD connect the communication module FX2NC-485ADP, but this raises the same question - what Protocol is used? Whether it is necessary in both cases to modify the program code in the PLC, do I need to configure extra modules? What typical solution to this problem?

    The easiest solution is to use SCADA that supports the MC protocol.
    For example, CITECT SCADA     using the serial port that is used for programming and a converter RS422 to RS 232.

    Hello Marek25,
    Your HMI - VT60      must have a MPS and a 25 pin Canon socket.  The cable must have a twisted pair of 2x0.5 shielded. The scheme for your case is on page 925. Resistors are 0.25 watts and can be soldered directly to the socket.  Realize also a bridge of terminals 4 and 5 as well as terminals 15 and 18. It is desirable that the cable is less than 50 meters in length. Check the specified PLC and HMI addresses.

    For SIMATIC S7 200 Address of CPU = 1 - 126.

    The schematic on page 884 is for an inverter SIMOVERT.  It has a RS232 serial port and the connection for this is different from PLC SIEMENS S7 200.

    Good luck!

    Hello Zahi Younis,

    You need to give some more information about this case. Where do you get the information from the Modbus protocol? Otherwise, Mitsubishi have their own communication protocol.

    This controller offers many opportunities for this. A RS485 port can be added - FX3U-485-BD, a USB port can be added from where to program or monitor PLC-FX3U-USB-BD. It also comes with Ethernet FX3U-ENET-ADP. MITSUBISHI HMIs support data transparency and could be programmed via the current RS485 port.

    It is possible that the program loaded in HMI has been created for a machine with more functionality and just a part of it is not used on your machine. It is also possible that somebody has erased part of the program loaded in the PLC.
