Function
The LogiCO2 Sniffer Modbus is a gateway for reading out measuring values and status (e.g. Alarms) from LogiCO2´s Safety Systems. It is only possible to read-out information from the Sniffer (read only). The Sniffer Modbus is connected to maximum eight sensors with or without a central unit. The Sniffer is monitoring the communication between the sensor/s and the central unit. If no central unit is installed in the Safety System, the Sniffer Modbus can communicate directly with the Sensor/s. The Sniffer Modbus is intended as a gateway from the LogiCO2 Safety System. The Sniffer Modbus communicates as a slave via Modbus RTU (RS485) to external systems. The Sniffer Modbus is power supplied from the LogiCO2 Safety System. Default setting is to read-out one Sensor (ID number 1) that is connected to a central unit.
Installation
Connect the cable marked “Connect to sensor” to one of the LogiCO2 Safety
System´s red cables. Use the cable marked “Connect to external system” to
connect the gateway RS485 to the external system.
Pinout red cable: RJ-45 Plug for RS485 Communication
- Pin 4 RS485 – (B)
- Pin 5 RS485 + (A)
- Pin 8 GND
Setup – with or without Central Unit
The default setting of the Sniffer is to communicate with a Safety System
together with a Central Unit. To change setting, remove the cover to access
the two DIP-switches.
Example (DIP-switch 2):
- To read-out sensors with ID-number 1 and 2, set the DIP-switch number 1 and 2 to ON. All other DIP-switches in OFF-position.
- To read-out sensors with ID-number 2 and 4, set the DIP-switch number 2 and 4 to ON . All other DIP-switches in OFF-position.
- To read-out eight sensors, set the DIP-switch number 1-8 to ON . All other DIP-switches in OFF-position.
