Siwarex JB Load Cell Calibration & Wiring Differences

Hello, it's understandable you're concerned about calibration without potentiometers. Your Siwarex JB 7MH4710-1BA doesn't require potentiometers for calibration – this is normal. Calibration is performed digitally through the Siwarex software and PLC programming (MS/U) for zero and span adjustment, not via physical potentiometers.

4-Wire vs. 6-Wire Load Cells

4-Wire Load Cells: Simpler, cost-effective, suitable for static or slowly changing loads. They're more susceptible to lead resistance errors, especially with longer cable runs.

6-Wire Load Cells: Offer greater accuracy by allowing compensation for lead resistance. Three wires supply excitation voltage, and three wires carry the signal. This minimizes errors due to cable length.

Potentiometers & 6-Wire Cells

6-Wire load cells, when used with a compatible Siemens weighing system, generally do not require potentiometers in the junction box. The compensation is handled electronically within the system. However, proper wiring is crucial to utilize the 6-wire benefit.

Siwarex MS (S7-200) vs. Siwarex U (S7-300) & Load Cells

Both Siwarex MS and U systems are capable of working with both 4-wire and 6-wire load cells. However, the Siwarex U (S7-300/400) generally offers more advanced features and potentially higher accuracy, especially when utilizing 6-wire cells and digital compensation techniques.

Important Resources:

• Siemens Industry Online Support - Siwarex
• Consult your Siwarex manual for detailed calibration instructions specific to your JB and PLC combination.

Double-check your wiring against the Siemens documentation. If you continue to experience issues, please provide details on your PLC configuration (MS or U) and the specific calibration steps you've taken for further assistance.

Troubleshooting Profibus PA Network with 1788-EN2PAR

It appears you've encountered a significant issue after adding termination impedance to your Profibus PA network. Here's a procedure to systematically check the problem, given the symptoms and devices involved:

1. Verify Basic Network Configuration & Power Supply:

Ensure the 1788-EN2PAR master cards are correctly configured with the correct bus address and termination settings. Double-check the power supply to all devices – insufficient power can cause widespread communication failures.

2. Segmented Troubleshooting:

Since adding termination brought the entire network down, and a second master exhibits the same issue, suspect a fundamental problem with the bus itself or the impedance value. Focus on isolating sections:

• Start with the MAG6000 Flow Transmitter: You can read this device. Use it as a known good point.
• Isolate Segments: Disconnect sections of the network (e.g., all pressure transmitters, then temperature transmitters) to see if communication restores with a smaller subset.

3. Check Termination & Bus Parameters:

Important: The termination impedance (100 ohms + 1µF) is *crucial*. Incorrect values will disrupt communication. Confirm this is the correct termination for your Profibus PA segment length. Use a Profibus PA tester to measure bus reflections and confirm proper termination. See Siemens Profibus PA Termination Guide.

4. Device Diagnostics (SITRANS P DS III & TH400):

Attempt to access diagnostic information from the pressure and temperature transmitters individually (if possible, even without full network communication). Check for internal faults or communication errors within the devices themselves. Use a handheld communicator or the device's configuration software.

5. Cable Integrity:

You've replaced the cable, but verify its integrity again. Look for physical damage, kinks, or improper connections. Use a cable tester if available.

6. SiePortal Resources:

For more detailed troubleshooting steps and FAQs related to your 1788-EN2PAR and SITRANS devices, please consult these resources on SiePortal:
