ind780batch configuration example
IND780batch – Configuration Example

This system is comprised of 1 scale, 5 automatic material feeds, 1 hand addition, 1 automatic discharge, 1 operator action station and 1 auxiliary control (mixer). The first thing to setup in this system is the Equipment modules and Control Modules for each Equipment Module.

2 – Operator Action Station

  • Equipment Modules in this system:
  • Scale
  • Operator Action Station

1 - Scale

  • First let’s setup the Equipment Modules and Control I/O Modules for the Scale.

1 - Scale

ind780batch configuration2
IND780batch - Configuration
  • For the Scale EM and CM we have the following I/O assignments:
  • Scale Fine Feed = ALC Card
  • Scale Fast Feed = Output 0.6.2
  • Material 1 = Output 0.5.1
  • Material 2 = Output 0.5.2
  • Material 3 = Output 0.5.3
  • Material 4 = Output 0.5.4
  • Material 5 = Output 1.0.1
  • Hand Add = Manual Operation
  • Discharge = Output 0.6.1
  • Auxiliary Mixer Control = Output 0.6.3

Now we can begin to setup our Equipment Modules. Fist highlight “Equipment Module” in the menu tree, then press Edit, New Equipment Module, and select Scale Equipment module.

ind780batch configuration4
IND780batch - Configuration

Next we can choose which scale this is (1 to 4), give our scale a name, and fill in the other parameter data as needed. In the next step we need to create our Control I/O Modules that are associated with Scale 1.

ind780batch control module configuration
IND780batch – Control ModuleConfiguration

This is the advanced tab of the Scale EM, and there are process parameters that can be adjusted here to optimize the material transfer functions.

IND780batch – Control ModuleConfiguration

Next, we need to configure the Weigh In Control Module

ind780batch control module configuration2
IND780batch – Control ModuleConfiguration

This is the advanced tab for the Weigh-Out CM, there are several parameters that can be configured here.

ind780batch control module configuration3
IND780batch – Control ModuleConfiguration

Next, since we have several materials that we will Automatically feed into the system we need to create a WI Transport Header Control Module. Since we had already assigned our outputs to the materials in our example layout we can enter in these output numbers into the WI Transport Header CM screen above.

ind780batch control module configuration4
IND780batch – Control ModuleConfiguration

Next, we need to configure the Weigh Out Control Module, and this will be the last CM for this scale. So we highlight “1-Batch Scale”, then right click, select New, then Weigh-Out CM. Now you will see the screen above and since our Discharge Valve is assigned to output 0.6.1, we enter this into the Feed Control box, with the Feed Source being Other I/O, so the control know to point the discharge to this particular I/O point.

  • For the Operator Action EM and CM we have the following I/O assignments:
  • Start/Resume PB = Input 0.5.2
  • Pause/Abort PB = Input 0.5.3
  • Stop button = Input 0.5.1
  • Attention Light = Output 0.6.4
ind780batch configuration7
IND780batch - Configuration

This is the Operator Hold Equipment Module, which has been given a description of “Operator Action Station.”

ind780batch control module configuration8
IND780batch – Control ModuleConfiguration

Next we need to define the Operator Action Control Module Inputs associated with this Operator Action Equipment Modules. We need to highlight the Operator Action Station, then right click, select New, then select Supervisor Action CM. Then you will see the right pane view show the above and we can enter in a unique Description, then assign the input addresses from our Operator Action Station, which is 0.5.2 for the Start/Resume PB, 0.5.3 for the Pause/Abort PB (Pause Batch and Abort Batch Inputs), and 0.5.1 for the Emergency Stop PB (Batch Run Permissive).

ind780batch configuration8

Next we need to define the Operator Action Control Module Outputs associated with this Operator Action Equipment Modules. We need to highlight the Operator Action Station, then right click, select New, then select Supervisor Status CM. Then you will see the right pane view show the above and we can enter in a unique Description, and then assign the output address for our attention light on our panel. In this case we will assign Batch Alarm and Operator Attention to our light with is output 0.6.4.

  • This completes the setup of the Equipment Modules, and Control I/O Modules.
  • Next we will look into how to setup the Material Paths.

feed algorithms which one to use
Feed Algorithms - Which one to use?

There are three types of Gain in Weight (GIW) Algorithms

Spill (short or erratic behavior)

K1 (most common)

K2 (fast feeds, downwards into scale)

Hand Add

These are your Loss in Weight (LIW) options

Spill

K1 (and less often, K2)

Dump to Empty (DTE)

Hand Add LIW

Hand Add DTE

feed algorithms behavior
Feed Algorithms - Behavior

Spill – The results of the previous feed are used to adjust the cutoff point of the next feed. Flow rate of the material is not monitored.

K1 – The cutoff point is adjusted as the Flow Rate varies during the feed. This is a dynamic behavior.

K2 – The cutoff point is adjusted as the Flow Rate varies during the feed. This is a dynamic behavior.

Dump to Empty – will attempt to completely empty the scale.

Hand Add – manual operation, waits for the operator to perform the material transfer and press OK to acknowledge material transfer is complete.

ind780batch feed algorithms
IND780batch – Feed Algorithms
  • Unfortunately the Final spill value is not always directly proportional to the Flow rate!
  • Some components are Proportional and some are not
  • The resultant Sum of all components is non Linear
  • The complex mathematical algorithms are described as the “PAC Algorithms”
    • Technology patented by P&G, & exclusively licensed to Mettler Toledo
  • It is these PAC Algorithms which result in the Qi’s accuracy and repeatability at higher flow rates

feed algorithms which one to use1
Spill Only (historic)

Very erratic flows or short feeds ( < 6seconds )

K1

Materials which have initial downward velocity of zero

i.e. horizontal entry

Materials which have slow flow rates

Even if vertical entry

Flow meters, Screw Feeders, Vibratory feeders and Discharge weighing

When Spill is proportional to Flow

Feed Algorithms - Which one to use?

The initial downwards velocity is zero

feed algorithms which one to use2
K2

Materials which have fast flow rates directed downwards into the scale

i.e. there is a large deceleration force

Hint: spills are small in relation to the flow rate as the deceleration component is negative and subtracts from the inflight material

Non linear spill with regards to Flow Rate

As Flow Rate increases the amount of material in flight does so only slightly

Feed Algorithms - Which one to use?

Material in suspension

The Algorithms - Summary
ind780batch material path configuration1
IND780batch – Material Path Configuration

To configure the Material Paths, we need to highlight Material Paths, right click and select New, then we will get a new Material Path screen on the right view pane. We can give the material a unique description, assign which scale (if more than one), this material will be assigned to, and choose the feed algorithm type, and transport header path number if there are more than one automatic material transfer.

ind780batch material path configuration3
IND780batch – Material Path Configuration

Now we need to setup Material Path 6 with is the Discharge (Dump to Empty) from the scale, so our Scale EM is “1-Batch Scale”, our Destination EM is “OUT_OF_CLUSTER”, the Feed Algorithm is “Dump to Empty”, and there is no Transport Header Path # since this is a single outlet from the vessel.
