Module Update
If you check your Health Status now, you should have everything online:
We'll deal with the service encryption in just a moment.
The other messages are all in relation to items requiring module updates. This can be resolved by right clicking
on the Controller and selecting Update Modules. This updates all modules connected to the Controller.
A module update is required whenever a programming change is made that requires the hardware to function in
a different manner. The Controller will advise you whenever this is required by generating a health status
message.
Enabling Encryption
To enable encryption click the Configuration tab of the controller and select Initialize Controller Encryption:
Disabling Encryption
To disable encryption, select the option to Disable Controller Encryption:
This disables encryption at the server end only. The result is that the controller will now ignore all messages
from the server as they are not encrypted. Similarly, the server will not understand any of the messages sent
back from the controller as they are encrypted with a key that the server no longer understands.
To disable encryption on the controller, the controller must be defaulted. This is a security feature and ensures
that the only way to remove encryption is physically on site.
