Hello professionals! Recently moving has made it challenging to reset a PLC if it malfunctions without the need for air travel. I am interested in finding a more cost-effective solution. I have heard that on SLC500s, you can reset minor faults by turning a key in a specific combination from program to run mode. Is there a specific option that needs to be activated in the program for this feature to work, or is it already set as default? Additionally, what is the most effective way to establish a remote connection for fault resets or program updates on machinery equipped with SLC500 5/03 processors? What hardware would be necessary for this setup? Luckily, I have a maintenance technician on-site who can handle physical connections or key toggling as needed. Any advice on this matter would be greatly appreciated!
1- To clear a faulted SLC, try slowly cycling the key from program, to remote, to run (and back to remote if needed) in an attempt to resolve any recoverable faults. You can also set a system bit (S:1/8) to automatically reset a recoverable fault upon power cycle. Changes to this bit must be made offline and then downloaded. If the fault persists, it may be unrecoverable. Remember to cycle through all positions twice.2- The 5/03 PLC features two serial ports, requiring one to be bridged to Ethernet for remote connections with a VPN Router. Consider using the Digi One IAP for DF1 to Ethernet gateway or the Stridelinx VPN router from Automation Direct. Upgrading to a 5/05 PLC could eliminate the need for the gateway, but may require modifications to hardware connected to the 5/03's DH485 port.
OkiePC stated that when the SLC is experiencing a fault, cycling the key to program, then to remote, and then to run can help clear any recoverable faults. You can also set system bit S:1/8 to automatically attempt to reset a recoverable fault upon power cycle. Changes to this bit must be made offline and then downloaded. If the fault persists, it may be unrecoverable. Additionally, the 5/03 PLC has two serial ports, making a remote connection to it usually require one of them to be bridged to Ethernet with a VPN Router. OkiePC recommended using a Digi One IAP for DF1 to Ethernet gateway and the Stridelinx from Automation Direct as a go-to VPN router. Upgrading to a 5/05 PLC could eliminate the need for a DF1 to Ethernet gateway, but may require replacing or modifying any hardware connected to the 5/03 DH485 port.
Hello! The key-switch reset is a built-in feature that doesn't require any additional settings in the SLC500 software. Regarding remote maintenance, it sounds like you're in need of a remote access solution. You could set up a VPN connection using a VPN router. This way, you can directly access the PLC just as if you're in the local network. For the SLC 500 5/03, you would need specific hardware - a 1747-AIC Isolated Link Coupler and serial cable would work fine along with your VPN router. Just ensure your maintenance technician can handle the installation and setup. You'll be able to monitor, troubleshoot, and update the PLC software remotely without any travel needed. This could save you time, effort, and of course money. It's been the standard route for many professionals in situations like yours.
Hey there! For the SLC500, the feature you're referring to should be set as default, so no specific activation is needed. As for remote connections, you could consider an industrial VPN router which would help establish a secure remote connection for programming updates or fault resets. Of course, the exact type of router you'd need would depend on your specific setup but models like eWON Cosy could work. Also, having an on-site technician is really helpful to handle the physical part of the setup. Always remember, the security of your connections is paramount, so using professional equipment is advised. Verify the compatibility of the router with the PLC and consider seeking professional help if unsure. Hope this helps!
Hi there! You’re right about the SLC500 series being pretty adaptable for minor fault resetting with the key switch. Typically, there's no special option that needs to be activated for that feature; it usually just works by default as long as you have the key switch set up correctly. For remote connections, a great solution would be to invest in a serial-to-Ethernet adapter that could link the PLC to your local network. From there, you can use software like RSLinx for remote access to handle both fault resets and program updates. Just make sure you have the proper cabling and maybe consider setting up a VPN for added security—the last thing you want is unauthorized access! Good luck, and kudos for getting your technician involved, that should definitely help streamline the process!
