    1. 780Qi and TE Quality Improvements Quantity Increases Quantifiable Results

    2. Overview • 780 and TE is not very different from a TE program using Full Setpoint control • Differences: • You write to different SD values to Start a Feed • You read from different SD values to determine the state of the Qi and its feeds. • You need to use a Qi Configuration software tool to setup certain parameters. It can be done from the front panel but is more cumbersome. • In most case your existing batching TE application can be modified quite easily to support the Qi model • When controlling multiple feeds into a scale the switching must be taken care of via a steering matrix (see last slide)

    3. Install TE development software

    4. Qi Intro – configured modules Material Path Equipment Channel Module Control Module EM MP CM 1 Scale OP Scale 1 2 3 OP 1 DIO Module Scale 2 4 5 6 FlowM 1 OP 2 DIO Module 7

    5. Example 1 Qi Intro – physical architecture MP4 MP5 MP6 MP1 MP2 MP3 MP9 EM 3 EM 1 EM 2

    6. Starting a Feed • The Qi Control Module, Equipment Channel and Material Path must be created in the Qi prior to starting a feed

    7. Qi Command SD’s • SDs with Comments are required and should be written to

    8. Common Command Values (CQ0104) • 1 Start Feed (Net Target) • 2 Start Feed (Gross Traget) • 4 Acknowledge Feed • 5 Abort Feed • 7 Control Override mode ON • 8 Turn FCE ON (in override mode, target contains length of time ON) • 9 Turn FCE OFF (in override mode) • 10 Back to AUTO mode

    9. CQ SD Info • PARTIAL LISTING of CQ’s

    10. Reading the Status of a Scale A • The following shared data contains the most important info • ED0901 – 8 bit status • ED0904 – Net Fed, zeroed at start and updated during feed (1 second) • ED0905 – Gross weight of Scale (or flow meter) • ED0906 – Flow Rate of Scale

    11. Status SD’s ( ED - - - - )

    12. What number in the ED ? • EXAMPLES • ED09 - - Scale A • ED10- - Scale B • ED03 - - Flow Meter M

    13. Status bits

    14. The important bits ( ED - - 01) • Bit 5 – Cycle active • Stays ON during the Feed including the Drain Time (Settling time) • Bit 6 – FCE ON • The is the high speed control OP that controls the feed. Status only DO NOT USE this in Ladder for control • Bit 7 – Acknowledge me • Set at end of feed and stays on until feed is acknowledged (command 4) • The acknowledge command is optional on a 780 (not when using a JagXQi) • Use TE code to extract the status of the bits for use within your program.

    15. Outputs • In this case Qi was configured so that the FCE was the O/P on the Scale card in slot 1 (DI0105). • Here we use it to drive a relay O/P sacrificing a bit of speed for convenience

    16. Qi wiring example with TE +V Control Material selection via TE FCE MP2 MP3 MP1 780 Outputs for the “Steering Matrix” • 3 material Controlled by 1 Qi O/P • Qi is in DIRECT Control of the FEED • !! Only ONE Matrix OP on at any one time
