AVW200 and default security features: these cannot be ignored

Compared to default security features
Cybersecurity is not just a trendy term, but also a top priority in daily work. In this era where data privacy is crucial, ensuring the security of monitoring systems is equally important as ensuring data accuracy. To this end, we have launched the "Default Security" program (Pakbus default encryption) - a measure aimed at comprehensively improving the security performance of data collectors across our entire product line.
However, significant improvements can sometimes bring unexpected situations. One phenomenon is that when you connect certain peripheral devices (such as AVW200 dual channel string analyzer module and CCFC outdoor observation and monitoring field camera) to PakBus ® The 'default security' feature may have an impact on new data collectors in the network.
A core feature of 'default security' is automatic activationPakBusEncryption function. This means that allPakBusCommunication between devices is protected: information is encrypted at the sender and decrypted at the receiver.
Some older devices (including AVW200, CCFC, and earlier PakBus products) do not support PakBus encryption. Therefore, when you connect them to the CR6 automated monitoring platform or CR1000Xe measurement and control data collector, these devices are unable to interpret encrypted information or return encrypted data. On the surface, it looks like the device has stopped working.
Methods to restore AVW200 to normal operation
Don't worry, you can restore the system to normal through the following two solutions:
01 Disable the encryption function of the data collector
useLoggerNetThe data collector supports software and device configuration tool (DevConfig) to connect to the data collector and then disable encryption function.
This method is effective, but it should be noted that it will lower the security protection level of the entire network.
02 in the CRBasic program
Using the EncryptEmpt() instruction
By adding the EncryptExcept() instruction in the program and setting your AVW200 (or other older devices) as an exception based on the PakBus address.
This method can maintain encrypted communication with other devices in the network while maintaining a high level of security.
The specific writing method in the CRBasic program is as follows

Please place this instruction in the CRBasic program 'BeginProg'Before the 'Can' line.
You can also set the address range, such as using
EncryptExempt (200202) to exempt devices with PakBus addresses 200, 201, and 202.
The 'default security' feature can indeed enhance network security, but may require slight adjustments when compatible with certain specific devices. By using the EncryptEmpt() command, you can ensure that security protection is not compromised while maintaining system functionality.
