JASCH QCS Integration

System Overview

JASCH Industries is a leading Indian manufacturer of Quality Control Systems (QCS) for the paper industry. Their systems are widely installed in Indian paper mills and offer excellent compatibility with the PowerFlow Dilution Control System via Modbus TCP.

Indian Market Leader

JASCH QCS systems are one of the most popular choices for Indian paper mills due to competitive pricing, local support, and good performance. Integration with PowerFlow Dilution Control is straightforward.

Supported Models

The following JASCH QCS models are supported:

Model Interface Features
JASCH QCS-5000 Modbus TCP Latest generation, easy integration
JASCH QCS-4000 Modbus TCP Widely installed, full profile support
JASCH QCS-3000 Modbus TCP/RTU Earlier generation, check Modbus TCP availability
JASCH Scanner Systems Modbus TCP Standalone scanner systems

Network Setup

Configure the network connection between the Dilution Control PC and the JASCH QCS system:

Physical Connection

  1. Connect an Ethernet cable from the control PC to the industrial switch
  2. Ensure the JASCH QCS computer/controller is on the same network
  3. Use CAT5e or CAT6 Ethernet cables for reliable connection

IP Configuration

Configure the control PC with a static IP address in the same subnet as the JASCH system:

Example Network Configuration

JASCH QCS IP 192.168.1.50 From JASCH configuration
Control PC IP 192.168.1.10 Same subnet
Subnet Mask 255.255.255.0 Standard Class C
Gateway 192.168.1.1 If required
Finding JASCH IP Address

The JASCH QCS IP address can be found in the JASCH configuration software. Navigate to System Settings > Network Configuration, or contact your JASCH service engineer.

Modbus Configuration

Configure the Dilution Control System to connect to the JASCH QCS:

  1. Open Scanner Configuration

    Go to Settings > Scanner Configuration

  2. Select Scanner Type

    Choose JASCH from the Scanner Type dropdown, or select Generic Modbus for manual configuration

  3. Configure Connection

    Connection Settings

    Interface Modbus TCP Standard protocol
    IP Address 192.168.1.50 JASCH QCS IP
    Port 502 Modbus TCP standard
    Slave ID 1 Default
    Timeout 3000 ms Recommended
  4. Configure Profile Settings

    Profile Settings

    Number of Databoxes 200 Match JASCH configuration (typically 100-250)
    Profile Register 0 Starting register address
    Data Type Float 32-bit IEEE 754
    Byte Order Big Endian JASCH default (verify with JASCH)
  5. Test Connection

    Click Test Connection to verify communication

  6. Save Configuration

    Click Save to apply settings

Register Map

The JASCH QCS exposes profile data via Modbus registers. The exact register addresses may vary based on JASCH configuration.

Typical JASCH Register Map

Register Count Type Description
0 400 Float (2 regs each) Basis Weight Profile (200 points)
400 2 Float Profile Average
402 2 Float Profile Sigma (2-sigma deviation)
404 1 Int16 Scanner Status
405 1 Int16 Profile Valid (0=Invalid, 1=Valid)
406 1 Int16 Number of Valid Databoxes
Confirm with JASCH

Register addresses and data formats may vary between JASCH models and software versions. Contact JASCH or check your JASCH documentation for the exact register map for your installation.

JASCH Contact for Register Map

To obtain the exact Modbus register map for your JASCH system:

  • Contact JASCH Industries technical support
  • Provide your JASCH model number and software version
  • Request the Modbus TCP communication protocol document

Zone Mapping

Configure the mapping from JASCH scanner databoxes to dilution actuator zones:

Mapping Parameters

Zone Mapping Configuration

Front Side Offset 10 Databoxes to skip at front edge
Back Side Offset 10 Databoxes to skip at back edge
Mapping Direction Front to Back Match physical layout
Number of Zones 48 Number of dilution valves

Verifying Zone Mapping

To verify correct zone mapping:

  1. Open the Profile Display in the main window
  2. Compare the displayed profile with the JASCH QCS display
  3. Verify the profile edges align correctly
  4. If possible, create a known disturbance and verify it appears in the correct zone

Testing & Verification

  1. Verify Connectivity

    Ping the JASCH QCS from the control PC:

    ping 192.168.1.50

    Expected: Successful ping response

  2. Test Modbus Connection

    In Scanner Configuration, click Test Connection

    Expected: "Connection successful" message

  3. Verify Profile Data

    Check the Profile Display panel:

    • Profile should update with each scanner traverse
    • Values should be in expected basis weight range
    • Profile shape should match the JASCH display
  4. Compare with JASCH Display

    Compare key values:

    • Profile average should match JASCH average
    • Profile sigma (2-sigma) should match
    • Number of valid databoxes should match
  5. Test Profile Response

    If safe to do so, create a small process disturbance and verify:

    • Disturbance appears in the correct position
    • Zone mapping is correct
    • Response direction is correct

Troubleshooting

Connection Problems

Issue Possible Cause Solution
Cannot ping JASCH IP Network configuration issue Verify IP addresses, check cables, confirm JASCH is powered on
Modbus connection timeout Modbus TCP not enabled Ask JASCH engineer to enable Modbus TCP server
Connection refused Wrong port or firewall block Confirm port 502 is open, check firewall settings

Data Problems

Issue Possible Cause Solution
Profile values are zero Wrong register address or scanner parked Verify register map with JASCH, check scanner status
Values are very large/small Wrong data type or byte order Try different byte order settings, verify Float vs Int
Profile looks mirrored Mapping direction wrong Toggle mapping direction in configuration
Profile not updating Stale data or scanner stopped Check Profile Valid flag, verify scanner is scanning
