1. A method comprising:
receiving, via a network of a process automation system, an alarm configuration request transmitted by a distributed control node (DCN) of the process automation system,
wherein the alarm configuration request includes a function block identifier of a function block, and includes the function block identifier based on the function block being executed by the DCN and/or being assigned for use in alarm monitoring by the DCN;
responsive to receiving the alarm configuration request that is transmitted by the DCN and that includes the function block identifier:
retrieving, from an alarms database, an alarm configuration file based on the alarm configuration file being stored in association with the function block identifier and the function block identifier being included in the received alarm configuration request; and
transmitting, via the network of the process automation system and to the DCN, the retrieved alarm configuration file,
wherein transmitting the retrieved alarm configuration file causes the DCN to implement alarm monitoring that conforms to the retrieved alarm configuration file.
