  • Q: Why can't I configure virtual IQs (vIQ) with an out-station number of 2,3 or 10?

    • Answer:

      These three vIQs are reserved by Trend Control Systems Ltd for Trend specific functionality and cannot be used.

      In addition to these three vIQs, there are two VCNCs (Virtual Communications Node Controller) connections which use an out station number, therefore these two VNCN node numbers cannot be used as vIQ out station numbers.

  • Q: How should I number virtual IQ (vIQ) out-stations?

    • Answer:

      There are several out station numbers that are reserved by Trend Control Systems Ltd that cannot be used and these are 2,3, and 10. In addition to these three, there are a further two that are used as VCNC (Virtual Communication Node Controller) node numbers which cannot be used.  As these out station numbers cannot be used, it is suggested that out station numbering is started at 11.

      This creates a simple relationship between the VIQs and their out station numbers, where the 1st vIQ is out station 11, the 2nd is out station 12, etc. If this or an alternative numbering system is used, please ensure that all out stations on a LAN have different numbers and please note that out station 119 is the largest out station number that can be used.

  • Q: What are the power requirements of a SIP?

    • Answer:

      The SIP (single and multiport variants) have a documented voltage range of 9 ~ 40 VDC and a nominal supply voltage rated at 24 VDC. At 24 VDC, the nominal current is 150 mA which gives a power requirement of 3.6 Watts.

      For safety, it is suggested the power supplies are dated and a suitable value is 25%. This gives a suggested power requirement of 4.5 Watts which will allow for any degradation of the power supply over time or temperature, in rush currents, and other devices connected at a later stage.

      Any 24 VDC power supply capable of providing at least 4.5 Watts will be suitable; this includes the MDR-20-24 (PSU/24VDC/1A) and the DR-75-24 (PSU/24VDC/3.2A) and these can be supplied by Synapsys. The MDR-20-24 is rated at up to 20 W so it is suitable of powering up to four SIPs, the DR-75-24 is rated at up to 75 W and is suitable for up to 16 SIPs.

      The 24 VDC Auxiliary Output Supply on the IQ3 (Terminal A Output 24V/0V ) is not suitable for powering a SIP, the Trend IQ3 Installation Instructions state this output is rated at 150 mA but the Closed Circuit Voltage drops to 20.7 V at full load (3.1 W); in addition, the limit of 150 mA is shared with the P Bus if an auxiliary P Bus power supply is not used. This makes this output unsuitable for devices such as the SIP and only suitable for low power devices such as sensors.

      When wiring any DC powered device, to ensure compliance with the current wiring regulations, the DC output should use the appropriate wiring scheme for extra low voltage (ELV) systems.

  • Q: How do I find the MAC Address of a SIP?

    • Answer:

      There are three conventional ways to find the MAC Address of a SIP.

      1. If you have access to the hardware, there MAC Address will be on a sticker on the side.

      2. If you have SIP Search, run it and the MAC address for each SIP on the network will be listed.

      3. From a command prompt on the same network, issue the command 'arp -a' and the MAC address will be listed against the configured IP Address.

      For 'arp' to report the MAC Address, a TCP/IP connection to the SIP must have been made previously, this can be done by logging on to it, pinging it, or running traceroute/tracert.

      The MAC address will be on the format 00:13:48:xx:yy:zz; where xx:yy:zz will be a unique code which identifies the SIP on the local Ethernet LAN.



  • Q: Why is my Trend display not showing values from the Daikin D-BACs (BACnet)?

    • Answer:

      This may be caused if the Instance number of the Daikin D-BACs unit is not configured correctly.

      The Instance number is the address of this BACnet device. It is set to 0 (zero) by default and a unique Instance number can be edited using the Daikin D-BACs software.

      We do have a SIP BACnet Trend range already loaded with a Daikin D-BACs configuration, 1 per 2 Daikin D-BACs air conditioning networks. One variant per Daikin D-BACs air conditioning network (64 indoor units, 128 indoor units, 192 indoor units & 256 indoor units).

  • Q: Can I make changes to a downloaded SIP Easy Solution?

    • Answer:

      Yes, the SIP is a fully programmable interface and SIP Easy solutions can be changed to suit your specific application.

       

      Once the SIP Easy file has been Restored to the SIP, please make the changes you need and then backup your changes with the Backup function.

       

      If you want to forward your changes to Synapsys for inclusion in to the SIP Easy Solution for other users, please email the Backup file to support@synapsys-solutions.com.


  • Q: A Temperature reading from an Indoor Unit is static and the graph has been the same and a flat line since it was last checked. What is the issue?

    • Answer:

      This indicates the indoor unit has lost its allocated Central Address.

       

      To resolve the issue, program the Central Address into the unit and power cycle the SIP

  • Q: How often are the Trend Modules updated when a 100 Point 1 vIQ SIP is used and the acquired Modbus/M-Bus points are redirected to an external Out-Station?

    • Answer:

      The SIP will update the Out-Station every time it receives data from the Modbus/M-Bus interface.


      Depending upon how many Modbus points were configured in the SIP, this update rate would be from about once a second per point for a SIP reading a few points to once in several seconds per point for a SIP reading many points. For an M-Bus SIP, this update rate would depend on the configured polling rate.

      There are no settings to control this on a percentage change basis or on a time basis so to control the amount of traffic on the Trend LAN use a From IC-Comms request to the SIP’s VIQ.

  • Q: How do I configure a SIP for use with an ACP InfraStruXure PDU Server?

    • Answer:

      The SIP should be configured:

      Connected to the InfraStruXure Server using one of the front Ethernet ports.

      With an IP Address compatible with the InfraStruXure Server.

      For a ModBus communications settings "Connection type" of TCP/IP.
      For a ModBus communications settings "Protocol" of JBus.

      The Map Points ModBus slaves "Slave address" should be configured with the configured slave address of the PDUs as documented in the InfraStruXure Server's schedule
      The Map Points table should be configured with the Register numbers as documented in the InfraStruXure Server' schedule.
      Address 30101 in the schedue should be entered as 30101.
      The Map Points table should be configured with the Data Type "Integer 16 bits unsigned".
      The Map Points table should be configured with the Function "4 - Input Registers".

      All the other settings are standard and configured as per the SIP Modbus Manual.

  • Q: Can I use conditional statements in the VIQ calculations?

    • Answer:

      Whilst there are many forms of calculation available within the SIP, unfortunately this does not include the use of conditional logic expressions at the present time. More information can be found in the VIQ calculator section of the product specific documentation available either embedded directly on the SIP or within this site.

  • Q: Why can I not edit IQD files for SXNC applications with SET?

    • Answer: Trend has updated SET and the current version cannot be used to edit these files, resulting in the need for a workaround. IQD files can be manipulated with older versions of SET (v6.4 and previous).
      One way to overcome this problem is to create a virtual drive on your pc where an older operating system like Microsoft Windows XP can function, thereby enabling the use of older versions of SET.
  • Q: Where is the Modbus/M-Bus configuration for the device I require?

    • Answer:

      Typically, we will not supply a document listing the ModBus or M-Bus configuration of our SIP Easy files. However, the datasheet relating to the SIP Easy file does list the Trend Module configured for the device.

      The ModBus/M-Bus configuration can be seen on the Map points page in the SIP/MODM/.../nVIQ or SIP/MBUS/.../nVIQ product or on the Meter Config page in the SIPE/MODM/.../nVIQ or SIPE/MBUS/.../nVIQ (M-Logger, IF-Logger) product.

  • Q: Can I collect the energy usage data in the SIPe range from the MySQL database using third party applications?

    • Answer:

      Energy data in the SIPe product range is available to third party's via email, FTP and/or MySQL queries.

      Emailing requires the smtp server configuration for sending a csv file via email to a local email address or for sending a csv file to an email address via an external smtp server (e.g. gmail).

      FTP (File Transfer Protocol) requires the destination FTP server configuration for receiving a csv file via FTP to a local or remote FTP server.

      MySQL queries can request the relevant data from the database in the SIPe but requires the correct Username and password (available by contacting support@synapsys-solutions.com).

  • Q: Why do I only get Alarm Names and not Alarm Labels in the Supervisor from SIP?

    • Answer:

      Generally, this is because IP Alarms and not LAN Alarms are configured in the SIP.

      To test this issue, set the Alarm destination fields in each vIQ to use LAN Alarms and not IP Alarms. To do this, ensure the 'Use IP Alarms' checkbox is un-ticked and the 'Alarm Address' and the 'On Remote LAN' fields have valid destination LAN and Node addresses.

      The reason the labels do not appear is 963 learns the Source when using LAN Alarms but does not learn the Source when IP Alarms are used.

  • Q: What is the maximum number of (Trend or vIQ) out-stations allowed on a Trend LAN?

    • Answer:

      The Trend protocol supports OS1 to OS119, but OS2, OS3 and OS10 are reserved for Trend comms (see previous FAQ). This means a total of 116 unique OSs (out-stations) per Trend LAN.

      This is sufficient when only 1 SIP is assigned per Trend LAN but VCNCs MUST be considered as OSs if multiple SIPs (and/or IQ3XNCs) are assigned to a single Trend LAN.

  • Q: What is the maximum recommended cable length between your pulse acquisition module and pulse meters?

    • Answer:

      The maximum distance for the pulse input of is 25-30 meters provided a low drop cable min 2mm2 is used.

    • Q: Does the SIP support I.C. Comms?

      • Answer: The SIP can support 'Data To' and 'Data From' Comms however 'Global' I.C. Comms is not supported.
