Note: After the import procedure, by selecting the Import tab, a report page displays. It contains the detailed logs of the latest import procedure, including any added or removed objects. Checking STT20 BACnet settings Specific STT20 networking information display in the Information Box provided after the import procedure.
Configuration Configuring the Fire network 7.7.3 7 NK823x BACnet Protocol The fire system connection to the NK8237 Modbus Gateway uses the BACnet protocol over IP. In the BACnet/IP communication with the fire units, the NK8237 Modbus Gateway acts as a BACnet client. The NK823x configuration in Composer include the definition of the IP addressing and the BACnet/IP connectivity. In both cases, the NK823x configuration must match what is expected by the fire system. Configuring the NK823x IP addressing 1.
7 Configuration Configuring the Fire network Routing Tables: NK823x can handle a static routing table to address multiple subnets via IP routers (for example, SAFEDLINK GAP stations). Any access to subnets that is not handled by the NK323x Default gateway must be defined as routing table. Note that, if a SAFEDLINK network includes both FS20 and STT20 units, two separate GAPs must be addressed and specific routing tables for two separate subnets must be defined accordingly.
Configuration Configuring the Fire network 7 192.168.2.1 to 254. Instead, Destination = 192.168.2.10 and Netmask = 255.255.255.0 define the single IP address 192.168.2.10. – IP address of the Gateway (GAP) that can provide connectivity to the destination subnet. TIP: Use the Ping button in the Tools tab to check that the IP connectivity is properly established between the NK823x and the routing gateway.
7 Configuration Configuring the Fire network 9. If the NK823x acts as BBMD, you have to configure the BBMD settings in the NS8011 BACnet Driver node: 7.7.4 – Press the BBMD Configuration button. The BBMD window that appears is organised in two tables. – In the upper table, set the required BBMD role of the NK823x components (max one per subnet): enable the check box on the right. – In the lower part, add the corresponding routing partner(s) in the other subnet(s).
Configuration Configuring the Fire network 7.7.5 7 STT20 BACnet connection to NK823x All STT20 fire panels must be linked to the NK823x Modbus Gateway. Proceed as follows: 1.

Maintenance and diagnostics The NW8204 diagnostic tool 9 WARNING Removing the USB key while the logging is enabled (without using the Safely Remove command) may cause the unit to restart or block (a manual restart is then needed). Always use the Safely Remove command before removing the USB memory device! Note: If you use the SD card as default log storage, removing a USB mass storage device temporarily set as the active log storage does not automatically set again the SD card as the active log storage.

Maintenance and diagnostics The Modbus Client simulator 9 Configuration info of the interfaces: information about the configured interfaces.
9 Maintenance and diagnostics The Modbus Client simulator The serial RTU connection requires a serial line between any serial port of the PC and the NK823x. Serial connectivity options, COM port, Baud rate, data bits and son on, can be configured in the simulator. Modbus data map The simulator can import the CSV file provided by the NK823x tool. Two file formats are supported: MP4.40: this CSV file format includes the Modbus objects organised in multiple tables: Word, Compact, Bit, and Command Tables.
Maintenance and diagnostics The Modbus Client simulator 9 One or more objects can be selected and control commands are available for the WordTables tab in the right-click contextual menu. Polling Log, to list the communication logs. History Log, to list the changes of state. CSV, to show the imported CSV file. Others, to support special functions to generate sequences of commands to the NK823x server. Note that the available sequences are pre-programmed in the Configuration.xml file.
9 Maintenance and diagnostics The Modbus Client simulator Search Menu Connection menu The Connection menu includes the following commands: Communication Settings, to select the TCP/IP or Serial RTU type and set the related parameters: IP address and TCP Port for TCP/IP, or COM port, Baud rate, and Data/Parity/Stop bits for serial RTU. Start / Stop the Modbus communication to poll the OPC server.

You wish to issue a control command (manned, unmanned, arm, disarm, ask, reset) towards one or more Modbus objects. 1. Select the WordTables tab 2. Click the object you want to command in the lists.
Maintenance and diagnostics Correcting communication failures 9 – Check to make sure all connections are correct, tight and that the quality of the cable is good. – Disturbances, caused by ground loops, if more than one device connects the shield to ground. Also, check that the shield is not grounded in the middle of the cable, for example, because it is accidentally connected to some grounded metal object.
9 Maintenance and diagnostics Correcting communication failures Check the network connections (Modbus TCP/IP) 9.6.2 LAN Diagnostic information about the LAN state can be obtained from different layers: Link state LED of Repeater or Ethernet adapters gives you information about the physical connection and the speed of the Ethernet link. 1) Select Start > Programs > Accessories > Command Prompt.
Maintenance and diagnostics Correcting communication failures 9.6.3 9 Control unit generated a fault If a control unit generated a fault, the problem may be in the connectivity between one of the control units (or subsystems) and the NK8237. Check network connections 9.6.4 RS232 Diagnostic information about the RS232 state can be obtained from the LEDs placed on the front panel of NK82xx. Typical problems of RS232 communication are: – Mix of RXD / TXD lines. – Line length exceeds the maximum of 15m.
10 Secure operation requirements 10 Secure operation requirements The security of systems requires appropriate planning and proper organizational procedures. Please review the following basic checklist of the issues to consider: Physical Security Access to the room and/or areas where the communication units and control stations are installed should be reserved to authorized personnel, and/or adequate protection should be put in place on the computers to prevent potential attacks or sabotage.
