I have inherited a Fatek FBs-40MC PLC with 2 FBs-6AD modules. According to the manual, the data should transfer to R3840 and beyond automatically. However, when I input a signal into Ch0 (R3840), the value remains static. Are there any additional steps or troubleshooting tips that I may have overlooked? I have attempted to adjust the jumper settings, but it only seems to affect the offset values (0 or 8192) and not much else.
All resolved! It appears that an external power source is required for the device to function properly.
I am experiencing a common issue with my PLC setup involving FBS 6AD. I have connected FBS 6AD to my PLC and supplied it with 24V DC from the PLC's 24V output. However, I am consistently receiving a reading of 8191 from CH 0 (R3840) and it remains constant without any fluctuations. Can anyone provide assistance with troubleshooting this issue?
Despite providing the FBs 6AD module and sensor power externally at 24V, the register R3840 (CH 0) is still displaying 8191.
Is it possible to obtain analog output from Fatek BA4D module? If so, how can this be achieved?
You might want to check the wiring again - improper connections can often cause these kinds of issues. Additionally, make sure that the software programming is done correctly; check if the addresses you've set match the physical layout. Also, it's possible that the module may not be seated properly, so reseating the module could help. Lastly, it may sound far-fetched, but there's also a possibility that the Ch0 channel is defective. If you have other channels free, try routing the signal to see if it changes on a different channel.
It seems like you may have already checked this, but just to be sure, have you verified that the operating mode switch of your FBs-6AD modules matches your operational requirement? The modules support three modes of operation: voltage input mode, current input mode, and thermocouple mode. Misalignment of the required mode could cause such issues. Also, double-check your wiring to ensure signals are received properly at Ch0. Lastly, consider rechecking your PLC configuration for any error. Upgrading to the latest firmware could also help if none of the above works.
It sounds like you've done some solid initial troubleshooting already. One thing that might be happening is that there could be an issue with your wiring connection or even your power supply. Inadequate power can cause a PLC to function incorrectly. Check the power supply and wiring connections, especially the one catering to Ch0. Alternatively, it could also be a fault in the module itself. If you have a spare FBs-6AD module, try to swap out and see if the issue persists. Lastly, consider updating the firmware, just to ensure there isn't a software glitch hindering the operation. Sometimes, these problems can come from the most unexpected places!
It sounds like you've already gone through some of the basic troubleshooting steps, so good job there! A common issue that might contribute to the static value is a problem with the signal connection or a malfunctioning ADC. Ensure your signal input is stable and correctly connected. Also, ensure the module is properly seated in the PLC rack to rule out any connectivity issues. You could also try setting the 'Operation Mode Selection' to 'Programming mode' during operation to see if the values change, then switch back to 'Run mode'. If the problem persists, you might consider getting a replacement module or having your current one serviced.
It sounds like you've done some solid troubleshooting already! One thing to consider is checking if the configuration for your FBs-6AD modules is correctly set in the PLC program itself—sometimes the data transfer doesn't work if the modules aren't properly addressed or initialized in the program logic. Also, ensure that the modules are powered correctly and that the signal inputs are configured to the correct range (0-10V or 4-20mA, depending on what you’re using). If everything looks good there, it might be worth looking into whether there's any input filtering set that could be affecting the reading. Good luck!
It sounds like you're on the right track with the jumper settings, but there might be a few other things to check. First, ensure that the PLC is properly configured to read from the FBs-6AD modules in your program; sometimes, the module needs to be explicitly enabled in the ladder logic. Also, verify the input signal type—if you're expecting analog signals, check that the input range and scaling settings in your PLC are correct for the signals you're applying. Lastly, use a basic debugging method to watch the raw input registers to confirm if the module is even detecting changes. If it's not, you may want to check your wiring connections or even consider a factory reset to eliminate any potential misconfigurations. Good luck!

Answer: Answer: The issue might be related to the configuration or setup of the PLC or the FBs-6AD modules. Double-check the wiring, module configuration, and any software settings that might impact the data transfer.
Answer: Answer: It is recommended to review the module's manual for detailed setup instructions. You may also want to verify the input signal connections, check for any communication errors, and ensure the PLC program is correctly configured to receive and process the input signal data.
Answer: Answer: Make sure that the input signal type and range are compatible with the FBs-6AD modules. Additionally, verify that the PLC program is correctly addressing the input data location (R3840) and that any necessary scaling or conversion functions are applied within the program.
