MUST HAVE SHOULD HAVE COULD HAVE Module # 070
Configuring the Qi Cluster • Objectives: • Know the sequence of configuring the Qi Cluster • Know how to setup a Channel • Know how to setup a Material Path • Method: • Demonstrate. • Class exercise to follow. • Reference material: • ChannelDef.doc • MaterialDef.doc
Hardware Control Configuration & Setup Sequence • Plan hardware options (scale, flowmeter cards, etc) • Construct (install cards) • Calibrate instruments • ------------------------------------------------------------------------------ • Plan PAC configuration (# Material Paths, Channels) • Configure PAC database • Commision Materials and Channels • Optimize PAC parameters • ------------------------------------------------------------------------------
PAC Config Steps – Overview (excluding Instrument setup) • Configure Cluster (not Qi Lite) • Set Global Parameters • Short Feeds, Comms Interfaces, K1 K2 Limits. • Configure the Channels • PAC >> Assign Channels • Note: if no channels have been licensed you will have access to SPILL ONLY algorithms • Fill in the “blanks” • Configure Material Paths • PAC >> Material Paths • Fill in the “Blanks” • Refer: ChannelDef.doc & MaterialDef.doc
WAIT – your PC must be Setup correctly for Qi Configuration • Change your laptops IP address to one that is compatible with the QiMPACT subnet mask • See table on next slide • Use Ipconfig to confirm new IP address has been accepted • A reboot may be required • Set Webbrowser to “Refresh each visit to the page” • Very important or cached pages are displayed • Connect app PC’s to Hubs or Switches • Use the “Ping” command to verify comms with your partners PC
PAC Config Notes: Cluster setup • QiMPACT must be in Program Mode • Ensure each QiMPACT has a unique number • View via Matroller Button • Important when more than one Qi in a Cluster • ( Can only be edited before assigning the Master ) • Decide whether to save changes to Master Database or to All • (PAC button) • Each QiMPACT in the Cluster must be told who the Master is • Go to each Qi in the Cluster, and enter Masters IP address • The Master must have all IP addresses entered into its configuration • Save Changes after checking: • “The Database Master's IP Address Has Been Entered Into All MATROLLERS”
System wide settings (Global) • In Program mode > PAC button • “Enable Short Feeds” checkbox • Must be enabled if you are expecting shorter than 7 to 8 sec feeds. • Actual limit is 6 seconds • ie Dedicated fast drum filling systems • Once the normal operating conditions are reached it is advisable to set limits to your K1 and K2 constants • Due to the nature of the K2 algorithms, erratic systems and upsets can cause the constants to “spike”. Enabling these limits will prevent this from causing any problems
Class Exercise • Setup Cluster (not Qi Lite) • Refer previous slides • Configure Global setting • Refer previous slides • NOTE: ALL configuration is done via the PAC button • Except for Matroller number
PAC Configuration Button Matroller number
Adding Channel 1 • QiMPACT must be in Program Mode when enabling a channel • Thereafter some parameters are editable in Runtime • (To use K1 or K2, channels will have to be licensed at this point) • Fill in the blanks • Refer PacDatabaseNotes.doc for detailed explanation of each parameter • Or view “Help” • HINT: save the page as a default and reuse • BIG HINT: do not skip channels • Later addition of channels may move your data !
Channel Defaults • Channel Configuration defaults • For the actual description of the parameters see the Technical manual Chapter 4, subsection: assigning channels or PacDatabaseNotes.doc • Some parameters can have recommended defaults, here is a list of defaults that will get you going although they may not be the most efficient. • Minimum Material addition 0 • Dump Trip Point 2 % of the Scale Capacity • Zero Flow Rate Threshold 5 scale divisions • (Note: unfortunately this threshold can vary quite a bit. If you have a noisy scale and the Stability light takes a long time to come on after a feed has stopped then your Zero Flow Threshold is set too low) • Flow Rate Unstable Scale 2 times larger than the above mentioned Zero FR Threshold • Minimum PAC Threshold 1.5 times the Zero Threshold • Feed Overide Time 0 • Minimum Slow Step Time 20 • Stable Measuring Device Wait Time 4 • Extract From: ChannelDef.doc • See: PACDatabaseNotes.doc for detailed explanation of parameters !!
Class Exercise 1: add Channel • Via the PAC button, ADD and CONFIGURE channel 1 using Scale A as the instrument.
Adding a Material Path • There is normally a minimum of one Material Path entry for each Control valve in the system • However – it is possible to create multiple Material Paths in the Database for a single Control valve (physical material) • WHY: • Routing of different materials through same pipework • A material may behave differently in certain circumstances ie batch size may be different in a DumpTo empty situation • QiMPACT must be in Program Mode when enabling a channel • Thereafter some parameters are editable in Runtime • Fill in the blanks • Refer PACDatabaseNotes.doc for detailed explanation of each parameter • Or view “Help” • HINT: save the page as a default and reuse • Hint: editing the Average Flow and Spill requires an extra “check” • Hint: resetting the Average Flow and Spill will cause the Algorithm parameters to be recalculated from scratch rather incremental changes • Useful when commissioning or process changes like a new valve
Material Path Defaults • Some parameters can have recommended defaults, here is a list of defaults that will get you going although they will not the be the most efficient. • Max Flow Rate Alarm Threshold 0 • Algorithm - GIW Spill or K1 to start with • Algorithm – LIW DTE or Spill • Slow Step timer Factor 1.5 • Alarm Only on SStep Timeout checked • Minimum Open Time 2 • Drain Time 6 • Flow Rate Limit Low 0 • Flow Rate Limit High 2 to 3 times what you are expecting • Spill Limit High 2 to 3 times what you are expecting • Spill Limit Low half the HighLimit negated • Algorithm Update 0.75 • Flow Rate sample period 2 • Destination Channel 255 if outside the Cluster else the channel that this Material is feeding into • Extract From: MaterialDef.doc • See: PACDatabaseNotes.doc for detailed explanation of parameters !!
Class Exercise 2: add a Material Path • Via the PAC button ADD and CONFIGURE a Material Path using Scale A as the instrument. • Add MP1 as a GIW material
Review Questions • What is the purpose of the “Short Feed Enable” option? • Can you add a Material Path before any Channels? • Can you configure the PAC and use a Qi to Control Feeds if no Channels have been licensed?
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.
