  1. Hardware, 010 – Revision notes • Scales use Controller board O/Ps for Feed Control (FCE’s) • Flow meters use their own on board O/Ps for Feed Control (FCE’s) • Set different addresses if more than one flow meter board is installed in a chassis • Set different addresses if more than one scale board is installed in a chassis • If using two speed control (QiLite only) the Fast Feed is controlled by an O/P on the multifunction board. (user can select which O/P) • The FCE should be in direct control of the physical control valve. (via Material Path selection matrix) • The EthernetIP interface is not active by default. It must be enabled and then its IP address set.

  2. Architecture, 020 - Revision notes • The Qi Ethernet network must be physically separate from the admin and plant control network. (VLAN is sometimes acceptable) • Do not rely on an Ethernet Switch to separate network traffic. • Note the correct way of wiring the Qi O/P • Controller board O/P1 is associated with ScaleA • Controller board O/P2 is associated with ScaleB etc

  3. Designing a Qi Cluster, 060 – Revision notes • Each scale or flowmeter is counted as a channel in the Qi database • Each material that is added is a Material Path in the database • A discharge from a scale is also a Material Path • LIW, discharges and flow meters have “Destination Channels” which MUST be entered correctly, the default value will not work. • Draw up a table with a row for each MP. The number of columns is up to you depending on how many parameters you feel like listing.

  4. Configuration, 070 – Revision notes • Suggested sequence of events: • Setup and configure all Scales and Flowmeters • Assign unique IP addresses and Matroller numbers to each QI ! • Build cluster and assign master. • Tip: master can be the least active Qi in the cluster. • Short feed enabled, if required. • K1 & K2 limiting, if required. • Add channels and configure according to suggested defaults. • Tip: do not skip any installed Scales or Flow meters if possible. (recommended) • Add material paths and configure according to suggested defaults. • Gotcha !! Any LIW or flow meter based feeds MUST have the correct destination channel entered! • Tip: perform initial configuration with Qi in Setup mode • Tip: editing most channel and material path parameters can be done while in Run mode, BUT NOT WHILE THE QI IS BUSY FEEDING.

  5. Commissioning, 090T – Revision notes • Make sure that the material is reset before the very first feed when commissioning a material • Spill and Flow limits must be very wide initially • Use Spill Only algorithm when first commissioning a material • Spill and Flow limits must be reduced once you have a good idea of where the material will stabilize • Use the “Material Transfer Check” screen to start test feeds independent of the host controller. (optional) • Check the status if your feed will not start. • Check that the Matroller is in Auto mode if feed will not start. • Use the “Material Transfer Process” screen to check your feeds !!! • Check that all SIX of the Spill and Flow limit blocks are GREEN !! • Check that the block: “Last Material Transfer Status” indicates a successful update. • Do you need to “Enable Short Feeds” ??? (yes if you expect feedtimes of less than 8 secs.) • Have you enabled K1 and K2 limit checking ?? (recommended.. But you must know what your normal operating ranges are first!!)

  6. Optimizing, 110T – Revision notes • The following parameters are important and should be optimized and/or checked on a routine basis. (in relative order of importance) • “Min PAC” flow thresholds • Spill and Flow min and max limits. • “Dump Trip Point” threshold. (If too small feed may not complete) • “Zero” and “unstable scale” flow thresholds. • “Draintime” (normally only after commissioning or experiencing noisy/unstable scale ay end of feeds)

  7. Qi communications, 120T – Revision notes • ControlNet is enabled by default • EthernetIP must be enabled and its IP and subnet mask entered. • Qi does not support DHCP • The Assembly slot is the Channels indexed position in the Cyclic data to the host controller. (Assembly slot number is found on the Channel config page) • After sending a Command always read the Command Status. • The Command Status MUST ALWAYS be made available to the operators, especially when the Status value is > than 5. • The AIM is optional code which simplifies interfacing to the Qi Matroller • The AIMse can be used to simulate a large cluster of Qi’s • Commands must be sent sequentially to the Qi. • If a Channel is busy feeding you cannot send another command to that channel • Monitor channels toggle bit, if it stops toggling disable material feeds • Monitor channelOK status bit, if it turn Off, disable feed and abort any feeds using this channel • Use an Ethernet switch that can be forced to use this mode: • 10 Mbits/second, HALF-Duplex, NO AUTO-NEGOTIATE
