    For the connection to the Kinco HMI to work, the Ethernet module must be in position 0. If necessary, change the position of the module

    

    Configure the IP of the Ethernet module. The module must have a fixed IP for communication with the HMI.

    

    Configure Command Byte and the number of permitted connections.

    

    Configure the S7-200 as a TCP server so that the HMI can access it. Configure TSAP and activate that all connections are accepted.

    

    Configure the CRC setting of your choice. CRC should be disabled to test the connection.

    

    Assign a memory area to the Ethernet configuration. The system suggests an address via "Suggest Address".

    

    When the configuration is complete, the corresponding data blocks for communication are created in the PLC.

    

    Important: In your Step 7 program, you must call the ETH0_CTRL subroutine in every cycle for the communication to work.

    Serial connection of the Simatic S7-200 via RS-232 or RS-485

    
    You can easily connect the Simatic S7-200 to the Kinco HMI via a serial interface, either using a programming cable via RS-232 or via a special RS-485 cable. The small 4'' Kinco HMI has one serial port, devices from 6'' have at least two serial ports. All serial interfaces support both RS-232 and RS-485 communication.

    The serial ports of a 7" Kinco MT4424TE HMI support both RS-232 and RS-485 communication

    RS-232

    
    RS-232 is a serial communication protocol for a point-to-point direct connection. A Siemens S7-200 can be connected directly to the HMI via RS-232, either directly via programming cable with COM 0 or with larger Kinco HMIs via an adapter with COM 1. All physical ports on the Kinco HMI support RS-232 communication. The physical connection COM 0 has an additional RS-232 connection (COM 2) on pins 7 (Rx) and 8 (Tx). A special serial cable is required to connect this to the Siemens S7-200.
    

    RS-485

    
    RS-485 is a protocol for serial communication with which the Kinco HMI can communicate with several participants via one connection. You can connect several Siemens S7-200s to a Kinco HMI via RS-485. Special serial cables are required for this.

    All Kinco HMIs with Ethernet connection can communicate with the Siemens S7-400 via Ethernet. The special feature of the S7-400 Ethernet driver is that it supports redundant communication with two CPUs.
    
    You must create a project accordingly in the Kinco HMIware, configure the communication and transfer the project to the HMI. The configuration is carried out in the following steps

    .

    1. Create a new project in the Kinco HMIware or open an existing project

    Configuration of the IP and rack numbers

    
    For the redundant connection to the S7-400, you must set two IPs and also the rack and slot numbers of the CPUs in the communication settings of the PLC in the Kinco HMIware. Proceed as follows:

    1. Enter the IP of the first CPU in the IP field
    2. Enter a combination of rack and slot number under Station Number. Station Number is one byte. The upper 4 bits are the rack number, the lower 4 bits are the slot number. For rack 0 and slot 3, for example, enter 3 (from hex 0x03) in the Station Number field.
    3. Enter the IP of the second CPU in the "Protocol Timeout 1" field. To do this, convert the IP into a decimal number. If you search the Internet for "IP Decimal Calculator", you will find tools to help you.
    4. Insert the rack and slot number of the second CPU in the format described above, this time in the "Protocol Timeout 2" field

    Serial connection of the Simatic S7-300/400 via MPI (RS-485) Point

    -to-point
    You can easily connect the Simatic S7-300/400 to the Kinco HMI via serial interface using MPI (RS-485). A maximum of one PLC can be connected directly to the Kinco HMI via the MPI point-to-point protocol. The small 4'' Kinco HMI has one serial port, devices from 6'' upwards usually have two serial ports.

    The serial ports of a 7" Kinco MT4424TE HMI support both RS-232 and RS-485 communication

    MPI (RS-485)

    
    MPI is a Siemens communication protocol that physically uses the RS-485 serial interface. A Siemens S7-300/400 can be connected directly to the HMI via an MPI point-to-point connection.

    Addressing the Siemens PLC variables

    Kinco HMI elements

    
    Kinco HMIware provides a large selection of elements for visualizing and changing PLC data. These include, for example, switches, lamps, input fields and much more. These elements can be easily linked to variables in the PLC. Selected variable areas are available for the Siemens S7-300/400 via the serial connection. The exact list of all addressable areas can be found below.

    Bit addresses

    
    You can use the following address ranges in the S7-300/400 via the serial connection to link to bit elements such as switches or lamps:
    

    • Flags (M.B 0.0-4095.7)
    • Outputs (Q.B 0.0-511.7)
    • Inputs (I.B 0.0-511.7)
    • Bits in data blocks (e.g. DB1_DBX 0.0-65535.7)

    
    
    Make sure to use dot notation for addressing.
    

    Word and Double Word addresses

    
    You can use the following address ranges in the S7-300/400 via the serial connection to link to Word or Double Word elements (16-bit or 32-bit) such as input fields, position animations, fill levels, etc.:
    

    • Marker blocks, addressed 16 bits at a time (MW 0-2046)
    • Flag blocks, addressed 32 bits at a time (MD 0-2044)
    • Output blocks, addressed 16 bits at a time (QW 0-126)
    • Output blocks, addressed 32 bits at a time (QD 0-124)
    • Input blocks, addressed 16 bits at a time (IW 0-126)
    • Input blocks, addressed 32 bits at a time (ID 0-124)
    • Data blocks, addressed 16 bits at a time (e.g. DB1_DBW 0-65534)
    • Data blocks, addressed 32 bits at a time (e.g. DB1_DBD 0-65532)

    Data blocks

    larger than 10

    
    Separate address ranges are available for addressing data blocks up to 20. There is a DBn_Dxx area for data blocks larger than 10. Any data blocks can be addressed via this area. The first one to three digits stand for the data block (1..255) and the following five digits for the address of the variable (00001..65536).
    
    Examples:

    • DBn_DBW with address 100001 is word 1 in data block 1

    Serial connection of the Simatic S7-300/400 via RS-232

    
    You can easily connect the Simatic S7-300/400 to the Kinco HMI via a serial interface. To do this, they can be connected directly via the PC adapter with COM 0 via RS-232. The small 4'' Kinco HMI has one serial port, devices from 6'' have at least two serial ports.

    The serial ports of a 7" Kinco MT4424TE HMI support both RS-232 and RS-485 communication

    RS-232

    
    RS-232 is a serial communication protocol for a point-to-point direct connection. A Siemens S7-300/400 can be connected directly to the HMI via RS-232, either directly via a PC adapter with COM 0 or, with larger Kinco HMIs, via an adapter with COM 1. All physical ports on the Kinco HMI support RS-232 communication. The physical connection COM 0 has an additional RS-232 connection (COM 2) on pins 7 (Rx) and 8 (Tx). A special serial cable is required to connect this to the PC adapter of the Siemens S7-300/400.

    RS-485

    
    RS-485 is a protocol for serial communication with several participants. Siemens uses the MPI protocol for serial communication with several participants. The normal serial interfaces of the Kinco HMI do not support MPI.
    
    However, there are special Kinco models that have their own MPI interface.
