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.
