Fire Projects recommend the Modbus Gateway provides a communication link between networks that use the Modbus/TCP communication protocol and Fire Alarm Control Panels (FACPs) resident on an NFN network.
Fire Projects recommend the Modbus Gateway 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 NFN network communicates with the Modbus Gateway through a NOTI-FIRE-NET network via the network port on any NCM. The Modbus communication protocol is consistent with Modbus Application Protocol Specification.
The Modbus Gateway Configuration Tool, a programming utility included with the Modbus Gateway assembly, is used to configure the Modbus Gateway. The Modbus Gateway is designed to need very little configuration. 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.
• Provide data such as event type, active/inactive, enabled/ disabled, acknowledged/unacknowledged, device type, analog value (4-20ma modules only) and system troubles.
• Support reads of up to 100 registers at a time. Analog values can be read 10 registers at a time.
• Receive configuration data from the Modbus Gateway Configuration Tool.
• Log diagnostic information.
• Send standard Modbus exception responses.
• Reduce configuration time by self configuring all nodes and points.
• The Modbus Gateway was designed to be compatible with standard Modbus/TCP masters.
