The CLSS Gateway can use a third-party client to monitor the nodes inside a Modbus
LAN network, and send alarm and event data of these nodes for the CLSS users.
NOTE: The Modbus interface provides supplementary data to the third party client.
NOTE: The Modbus details in this section are related to the NOTIFIER-UL panel.
7.1 Operation
The CLSS Gateway acts as a slave device to a Modbus master application and offer the
Modbus monitoring functionalities to the CLSS Gateway users.
NOTE: The Modbus master application communicates with one or more panels over an
NFN or a high-speed NFN network.
7.2 Functionality
With Modbus configurations the CLSS Gateway can:
•
Communicate with an NFN network through an HS-NCM or NCM
•
Directly connect to a single FACP in an NFN network
•
Support Modbus Application Protocol Specification V1.1b.
•
Monitor up to 10 FACPs.
Note: Additional FACPs require additional CLSS Gateways to the NFN network.
•
Support a maximum of 2 Modbus clients or masters.
7.3 Recommended Cybersecurity Practices
