Modbus Gateway Serial Communication Protocol

Modbus Gateway by Notifier provides a communication link between networks that use the Modbus/TCP communication protocol and Fire Alarm Control Panels (FACPs) resident on an NFN network.

The Modbus Gateway communicates with the NOTI-FIRENET network via the network port on any NCM. The Modbus communication protocol is consistent with Modbus Application Protocol Specification . The Modbus Gateway is designed to need very little configuration; no separate configuration utility is required. In most applications you will only need to enter the TCP/IP settings for your network and the nodes you would like to monitor. The gateway will automatically map all the configured points and supply you with a user friendly comma-separated value report that defines the mapping.

• Compatible with standard and high speed NOTI-FIRE-NET
• Monitor four compatible NFN or HS-NFN nodes not including the Modbus Gateway node itself
• Log diagnostic information
• Send standard Modbus exception responses
• Reduce configuration time by auto-discovering and mapping points
