Product Issue Notification
2023-11-06
Issued Product: tGW-700 series, GW-2200 series
Affected Duration: 2023/Sep/15 ~2023/Nov/3
Issue: Modbus communication fails in IPv6 network if SLAAC is enabled.
Issue Description：
- When the network environment where the module is located has enabled the IPv6 SLAAC function of the Router, it will disable the Modbus communication of the module.
- The SLAAC function is similar to the DHCP function in IPv4, which is used to assign IP addresses to modules.
- If the problem happens to the module, you can still use Web Browser to login to the module, and you can also use eSearch utility to set IP and update FW of the module.
Solution: Update the FW
- For modules shipped from 2023/11/6, the factory has fully reworked the FW to a new version to resolve this issue.
- Customers can download the new version of FW to update the modules they have.
