The Application of modbus TCP in hmi

Ⅰ. Reasons for WECON hmi choosing modbus TCP/IP

1. The application layer of WECON HMI makes use of Modbus TCP, which makes industrial Ethernet data exchange achievable.

2. It’s easier to interconnect with different systems: available to management network, real-time monitoring network and field devices communication.

3. Low cost of network’s implementation: available to apply a common network component.

4. High data rate: high transmission capacity, the transmission result of 100M Ethernet is 4000 Modbus TCP messages per second, while each message can transfer 125 words, which is equivalent to 4000×125=500000 analog data (8000000 switch).

  

Ⅱ. Parameter Settings

   The case here PC is set as Slave(lower computer), and touch panel as Master(upper computer).In this way, PC can communicate with HMI.

   The IP address of PC is set: 192.168.1.2. The two screens of project is edited by the use of WECON configuration software, the device type of one is chosen ModBus TCP Slave, the other is ModBus TCP Master.

   The project of Slave is downloaded to HMI and Master’s is simulated online.The network of HMI and PC are connected by communication cable.

 * Setting of HMI project

   The setting of communication port configuration: 

   The communication port is selected Ethernet and device type is ModBus TCP Slave. The Ethernet parameter is set: 192.168.1.2:502(this IP address should be the same to PC’s). The network type is set: TCP_Client_2N. The setting is as shown in figure 1.

   The setting of communication port configuration: the communication port is selected Ethernet and device type is ModBus TCP Master.The Ethernet parameter is set: 192.168.1.201:502(As long as this IP address is different from HMI’s in the same network segment). The network type is set: TCP_Client_2N. The setting is as shown in figure 4.

Ⅲ. Conclusion

   Modbus protocol is field-bus protocol which only consists of physical layer and data layer. It’s particularly suitable for the application situation with simple architecture and low cost. Through supporting Modbus TCP/IP protocol, WECON touch panel is able to communicate with PC and other devices.It not only reduces the cost of system design, but also increases the versatility of the equipment, which provides convenience for users.

How to map

1 Click on Settings-->；Address Mapping

2 Click Word Addr to set word address mapping

Here

l Source addresses are the external addresses.

l Target addresses are the external addresses such as HDW7.

l Mapping mode are read and write by default.

l Now Length 

If you set length 1 ，source address 421 ， target address HDW21

That means the address HDW21 maps 421， only one address mapping.

If you set length 2， source address 47， target address HDW7.

That means the address HDW7 maps the address47 and the address HDW8 maps the address 48， two addresses mapping.

Wecon HMI Multi-link instruction

1. Notes

Use of multi-machine connectivity， please note the following precautions:
1. Please ensure the master and slave is the same as the project. In addition to the master and slave parameters.
2. In order to ensure the project runs correctly， it is recommended to use the script. To use the script， the script used in the external address must be added to the [Project Configuration] / [System parameters] / [address] additional multi-level interconnect.
3. Master and slave interface parameters must be the same.
4. In the choice of master and slave protocol， the protocol must ensure that the order is the same.
5. Slave station number must be consecutive numbers starting from 1， can not be repeated.
6. Set the number from the machine the more communication speed may be slower.
7. Using the multi-machine connectivity， it is recommended to use RS485 communication mode， when only one from the machine， you can also use the RS232.

2. Use of multi-machine interconnected on Suggestions1. In order to avoid future trouble， please try to keep master and slave is the same as the project.
2. Try not to use the script， if we must use， use read-only script (which can only read data from the PLC can not write).
3. Although the non-slave multiprocessor interconnection agreements not to use the serial port is actually connected PLC， but is not available at this time. For example， COM1: MODBUS RTU， COM2: Multi-Link Protocol. Although the COM1 from the machine did not pick the MODBUS PLC， but this time can not pick up COM1 other PLC.
4. The number of received more from the machine， in theory， communication speed is slower. (Pick six from the current test machine， update requires 1 ~ 3s).
5. For immunity may be appropriate to reduce the baud rate.
6. Multi-computer interconnection protocol validation 1 7 EVEN unavailable.
7. Internal registers associated groups
HSX180.0 interconnected multi-machine configuration file to delete
HSW181 modify master and slave: 0: Slave 1: Host
HSW182 Station No.
HSW183 number from the machine
3. Q & A : 
All of the following problems are no problem in assuming the premise wiring:

Q1: When the customer feedback on a multi-machine Internet communications are not， please confirm with the client the following points:
*  Check whether the project configuration is correct.
[Project Configuration] / [System parameters] / [address] for additional multi-level interconnect (see Figure 1)
*  Check the project‘s master and slave. Screen only 1 host， the rest from the machine. Slave station number is the consecutive number starting from 1.

Figure 1

Q2: Why can display from the machine， but can not write， or write data after the error， write dislocation?
*  Check the host project. [Project Configuration] / [System parameters] / [] multi-level interconnect additional address number from the machine and you pick the number from the machine are the same. (Can not write， write data after the error)
*  Check the project from the machine. [Project Configuration] / [System parameters] / [address] multistage interconnection additional HMI station No. 1 is from the beginning of continuous data. Whether the repeat. (Can not write， write data after the error)
*  Refer to Figure 1， see the stop bit， data bits， parity bit is consistent with Figure 1.
(Can not write， write after the data errors， write dislocation)
*  Compile all works， check the project directory MLAddrInfo.xml are the same. Please use text comparison software comparison. To be exactly the same. (Can not write， write after the data errors， write dislocation)
*  Check whether the script. If you use a configuration script in the [project] / [] multi-level interconnection does not add additional addresses， you must add. (Some data not shown)

Q3: screen data is not run correctly (in a case of using a script)
*  If you use the script is not read the script， please go to the customer‘s engineering and analysis.

WECON LEVI HMI In Hybrid Bus System

   WECON LEVI series HMI is well-known for its technology customization. We can customize the HMI for customer’s requests. The hybrid bus system’s power source is diesel and battery. The bus uses diesel and battery when it’s running， and the battery is charged when the bus is stop.

   In hybrid bus system， the HMI needs to display the bus’ speed， the battery power， and the battery failure alarm and other information.

   And when the bus opens the backdoor， the HMI need to display the real time video of the backdoor， to let the bus driver get clear information about the back door the passengers to get off， to ensure closing the door and running safety.
