1 Communications Node Controller Communications Node Controller Description The Communications Node Controller () interfaces between a Trend Supervisor or Software Tool and the Trend network (RS232 to Lan). It is available in an IP30 enclosure (NBOX) or can be supplied without an enclosure for mounting inside a Trend device, e.g. an IQ controller. There are 230 V and 2 V supply versions. A boxed battery backed version is available (230 Vac only). Features Automatic network test. 11 node addressable. 2 Vdc auxiliary supply output. 230 Vac or 2 Vac/dc supply versions.

2 FUNCTIONALITY The interfaces between a local device connected via the RS232 port (e.g. an NDP, or a PC running a Trend Supervisor or Software Tool) and the Trend Lan; it also provides certain network maintenance operations. The continually monitors the Lan, if it receives data that is addressed to a different node it passes it on around the Lan via its transmit port. If it receives data for its own address, it will transmit it to the RS232 port. When data arrives from the RS232 port, it transmits the data onto the Lan via the transmit port. receive port Local device (e.g. Supervisor) RS232 port transmit port The also monitors Lan integrity by performing continuous checking of network messages. Alarm messages are generated whenever a problem occurs. IQ Trend Lan RS232 NDP IQ HARDWARE Packaging: The can be provided boxed, or as a board version. Boxed version: The can be supplied in a plastic enclosure with a transparent plastic flip-up terminal cover (NBOX//...). It has 3 point mounting to facilitate installation. There is an optional battery backup to keep the node functioning in the event of mains failure (NBOXB// Vac version only). An optional metal enclosure with cable gland knockouts is available (ENCLS/MBOX/IQ22x). Board version: The board version will fit inside certain IQ controllers. The controllers can be ordered pre-fitted with the node (e.g. IQ21//...), or the node can be retrofitted by using the appropriate fitting kit (KIT/NODE/IQ23x for IQ231/233, KIT/NODE/IQ2x for IQ21/22, or KIT/NODE/IQ25x for IQ250/251). Network : The two part network terminals are for 2 wire cables. The standard Trend node features are identified (Lan OK, TX, RX indicators, bypass relay, network alarm generation). Address Switch : The device address on the local Lan is selected by address switch poles 1 to 7. It may be set in the range 1, to 9, 11 to 119 and must be unique on the local Lan. Dumb/Normal Switch: The dumb/normal switch setting (SW1, pole 8) is ignored by the. Baud Rate Links : The local Lan and local device (RS232) baud rates are set by two sets of links to 19k2, 9k, k8, or 1k2. The local Lan baud rate must be set to match other nodes on the local Lan. The local device (RS232) baud rate must match the local device. Network bypass relay : In order that the network continues to operate if the fails, a node bypass relay is fitted to maintain network integrity in the event failure of the node s power supply, of failure of the node itself. The bypassing of a node will be recognised by the downstream node, and reported as a Lan Changed alarm. Fusing: No replaceable fuses are fitted. Protection is proved by a self-resetting thermally protected transformer. The 2 V version is protected by a self-resetting PTC device. Auxiliary supply: Then can supply 2 Vdc ±10 % at 150 ma maximum to a peripheral device (e.g. NDP). RS232/Lan connections: The local device connection is referred to as the RS232 port on the NBOX version, and as the Device B connection on the board version. The Trend Lan is referred to as Lan A. RS232 port (NBOX) Trend Lan (Lan A) local device RS232 Dev B, modem (J1) (board) The local Lan (Lan A) connection is duplicated on the board as the Device A RS232 connection (J15). If an RS232 device were to be connected to the RS232 connector (Dev A), the Lan connection (Lan A) would be effectively disconnected. Battery Backup: NBOXB//230 (230 Vac version only). Rechargeable batteries maintain node operations for 20 minutes (typical) during mains failure. The battery circuit is enabled by two links (J12, J13), and by default the battery circuit is disabled (OFF). The battery links should be moved to the ON position after power up to enable the battery backup. The unit should be powered on for at least 1 hours after moving the links to the ON position to charge up the batteries. Power: The battery backed boxed (NBOXB//230) can only be supplied in 230 Vac version but the boxed version without the battery backup (NBOX//...) can be supplied in 230 Vac and 2 V(ac or dc) versions. The 230 Vac version is supplied with an optional supply terminal shroud. The board version requires 2 Vdc, or 18 Vac (transformer isolated), or Vac (transformer centre tapped) 2 Communications Node Controller TA20021 Issue 1/C 27/05/0

OFF if Lan fault (e.g. baud rate conflict). Connectors: Two part connectors are used throughout to facilitate wiring. A busbar is provided for screen termination (NBOX(B) only). FIRMWARE Alarms: The also helps to maintain a high level of network integrity by performing continuous checking of network messages. The following alarms are generated when faults are found: Remote LAN From on Lan xx - Lan Broken NKBK - a break in communications over the local Lan. Lan OK NKOK - local Lan communications are restored. Lan Changed NKCH - a node has gone from or been added to the local Lan. Duplicate address NKDA - the s address is duplicated on the local lan. It will deliver these alarms to the RS232 port local device in the format required by the supervisor (text or critical). Device Ok DVOK - has detected that the local device is connected and active. Device Dead DVDD - has detected that the local device is either disconnected or is inactive. These alarms are transmitted on the local Lan. Any other supervisor connected to the local Lan will receive these alarms. Identification: The will reply to a request for details sent to address 10 from the supervisor or software tool running in the PC connected via RS232. If the local device is dead, the identifies itself to w Comms as v5.xx. Alarm Language: Some Trend Supervisors or software tools are able to set the to report its network alarms in foreign languages (English, Spanish, Finnish, Swedish, Norwegian, Danish, German, Italian, Portuguese, French).
