Frequently Asked Questions (FAQ)
Question
How do I add a peripheral card with two high-speed up/down counters to my PLC 1200 if it does not have integrated counters?
Answer
To add a peripheral card with two high-speed up/down counters, you need to first check the specifications of your PLC 1200 to confirm that it does not have integrated counters. If this is the case, you should purchase a compatible peripheral card that supports two high-speed counters. Install the card in the appropriate slot of your PLC 1200 and configure it using the PLC programming software. Ensure that the counters are correctly set up to match the requirements of your application.
Question
What steps should I follow to create a functional block that compares the two counters and generates a speed reference for the slave?
Answer
Creating a functional block involves several steps. First, you need to program the PLC to read the counts from both high-speed counters. Next, implement a comparison algorithm within the PLC’s programming environment to calculate the difference between the two counters. This difference will represent the error. Finally, use this error value to generate a speed reference signal that is proportional to the error. This can be achieved by applying a suitable mathematical formula within the PLC program.
Question
How do I add a D/A converter to generate an analog speed reference signal if the slave accepts speed reference with an analog level?
Answer
To add a D/A converter, first, ensure that your PLC 1200 has an available slot for a peripheral module. Purchase a compatible D/A converter module and install it in the PLC. Configure the D/A converter in your PLC program to convert the digital speed reference signal generated by the functional block into an analog signal. Connect the output of the D/A converter to the input of the slave device that accepts analog speed reference signals.
Question
What should I do if my PLC 1200 contains an HSC module, and I need to provide the error in analog form?
Answer
If your PLC 1200 contains an HSC (High-Speed Counter) module, you can use it to count the pulses from the master and slave signals. To provide the error in analog form, you need to add an analog output module to your PLC system. Configure the PLC program to calculate the error based on the HSC module’s counts and output this value through the analog output module. Ensure that the analog output module is correctly connected to the slave device that requires an analog error signal.
Question
Is it possible to use PWM for speed reference if my PLC 1200 is a DC version?
Answer
Yes, if your PLC 1200 is a DC version, it integrates PWM (Pulse Width Modulation) functionality. You can use this feature to generate a speed reference signal for the slave. Configure the PWM module in your PLC program to output a signal that varies in width according to the error calculated from the counter comparison. This PWM signal can then be used as a speed reference input for the slave device, providing a proportional control based on the error.
Question
Can I use the PLC 1200 to manage multiple slaves, and how should I configure it for this purpose?
Answer
Yes, the PLC 1200 can manage multiple slaves. To configure it for this purpose, you need to set up multiple high-speed counters, one for each slave. Create a functional block for each slave to compare the master and slave signals and generate the corresponding speed reference. Ensure that the PLC program is designed to handle the simultaneous processing of multiple slaves. This may involve setting up separate communication channels or using multiplexing techniques to manage the input and output signals for each slave efficiently.
Common Troubleshooting
Issue: PLC 1200 Not Recognizing the Peripheral Card
Symptoms:
The PLC 1200 does not detect the newly added peripheral card with two high-speed up/down counters. The system logs indicate communication errors or missing hardware.
Solution:
Ensure that the peripheral card is properly connected to the PLC 1200. Check the power supply and verify that the card is compatible with the PLC model. Update the PLC firmware to the latest version and re-check the configuration settings. If the problem persists, consult the hardware manual or contact technical support.
Issue: Counters Not Counting Correctly
Symptoms:
The high-speed up/down counters on the peripheral card are not counting pulses as expected from the master and slave signals. This results in incorrect speed references for the slave.
Solution:
Verify the input signal connections to the counters. Ensure that the input signals are within the specified range and frequency for the counters. Check the counter configuration parameters in the PLC program to ensure they are set correctly. If necessary, recalibrate the counters or replace the peripheral card if it is faulty.
Issue: Incorrect Speed Reference Generation
Symptoms:
The functional block designed to compare the two counters and generate a speed reference for the slave is not producing the correct output. The slave is not receiving the expected speed reference.
Solution:
Review the logic of the functional block in the PLC program. Ensure that the comparison logic is correctly implemented and that the output calculation is accurate. Debug the program by adding diagnostic outputs or using a PLC simulator to trace the execution flow. Correct any logical errors or misconfigurations in the program.
Issue: Analog Speed Reference Not Generated
Symptoms:
When the slave requires an analog speed reference, the PLC 1200 fails to generate the correct analog signal using the D/A converter. The slave does not receive the proper speed reference.
Solution:
Check the configuration of the D/A converter module in the PLC 1200. Ensure that the analog output settings are correctly set for the desired range and resolution. Verify that the input to the D/A converter is correctly calculated from the error signal. If the problem persists, test the D/A converter module with a known good signal to ensure it is functioning properly.
Issue: High-Speed Counter Module Not Functioning
Symptoms:
The PLC 1200’s high-speed counter module is not functioning as expected, leading to inaccurate counting and speed reference generation.
Solution:
Confirm that the high-speed counter module is properly installed and configured. Check the firmware version of the module and update it if necessary. Ensure that the input signals to the counter module are within the specified parameters. If the module is still not functioning, it may be defective and should be replaced.
Conclusione
In conclusion, replacing the old Ar7 card with a PLC 1200 for managing master and slave phase signals requires careful configuration. By adding a peripheral card with two high-speed counters if necessary, you can ensure the PLC 1200 performs the same function. Implementing a functional block to compare the counters and generate a speed reference for the slave, proportional to the error, is crucial. If your slave accepts speed reference via an analog level, include a D/A converter. Additionally, if your PLC 1200 has an HSC module and requires an analog error output, add an analog output module. For PWM needs, the DC versions of the PLC already integrate this feature. With these steps, you can successfully replicate the functionality of the old Ar7 card.
