The NET Concentrator System (NCS) has a versatile multipoint analog alarm (–MAA) option that allows users to set up simple or dynamic alarming schemes. The option uses a built-in ISaGRAF program providing a flexible alarm configuration that is accessed via Web pages through the onboard Web server. It allows users to configure as many as 32 alarms that can be assigned to any of the eight relay outputs on the relay output module (ROM). This enables each relay output to be driven by one input/alarm or multiple inputs/alarms. Each alarm can be configured as high or low with its own deadband setting.
