Question:
Can I use two PLCs working in redundancy with the same driver?
Solution:
Yes. To do so, you must enable the option BackUpAddress on IOKit’s Ethernet tab, and insert the backup IP. The IPs will automatically be switched once the main IP fails, or then via scripts in IOKIt’s tags.
You will only need one driver’s license, since it will be communicating effectively with only one of the PLCs. This means that in this case, it will be impossible to communicate with two PLCs simultaneously.
