Yes, that is necessary.
The HX controller of the TC6 project must be made ready to be able to send the alarms for the project. This requires a Management PC connection via the Ethernet port or serial port, and the 'Print Messages' option must be enabled.
In order to 'activate' these changes, it is necessary to re-commission the project. It may also be the case that a Management PC driver needs to be purchased.
An exception to this is if, for instance, a local TC ServeCenter PC is replaced in the project by Priva Alarms. In that case, the Management PC and 'Print messages' option are already active, so re-commissioning is not necessary.
