Hello everyone, I am encountering an issue with a 1734-AENT Ser A 3.005 point I/O module that is not establishing a connection with a 1768-ENBT ethernet module. The green LED on the network status is flashing, indicating a potential CIP connection problem as per the manual. I have configured the "Chassis configuration" in Rslinx and attempted configuring the IP address both physically and through BOOTP/DHCP software. Despite successful pings from CMD, parameters are not displaying on the Internet page, as noted in the manual for this series. In RSlogix500, I have adjusted settings like "Compatible Keying" and "Disable Keting" without resolution. The program displays error 16#0204, typically attributed to Ethernet wiring or power supply issues. I have tried changing both power supply and Ethernet wiring, including direct and crossed connections, with no success. Additionally, a firmware update to version 3.012 on the I/O point did not resolve the issue. Could this indicate a faulty module or is there an error on my part? Any assistance would be greatly appreciated. Notably, the PLC being used is a 1768-L43S Rev.19.11, with two ethernet modules (192.168.1.1 and 192.168.1.200) Rev.4, and the assigned IP address for the Point I/O is 192.168.1.139.
It may seem like a trivial question, but are the addressing thumbwheels properly set to 999? Past issues have arisen when installers mistakenly thought they had correctly set the thumbwheels, but they were not securely clicked into place. I have always adjusted the chassis configuration in the Logix5000 program by going online and specifying the chassis size. I was unaware that this could also be done through RSLinx.
In a forum discussion, user beethoven_ii raised a concern regarding addressing thumbwheels not being properly set to 999. This can result in installation issues when electricians fail to click the thumbwheels into the correct position. Typically, chassis configuration in the Logix5000 program is adjusted online by setting the chassis size. However, there may be a possibility to configure it through RSLinx as well. I have attempted to address the thumbwheel settings by resetting them first to 888 to clear any previous configurations, then adjusting them to 999. Despite trying to configure them through BOOTP/DHCP software, I have not had success. Additionally, I have experimented with changing the IP directly from the thumbwheels, noting that only the last part of the network changes in this process (e.g. 192.168.1.xxx).
After setting the IP address on the 1734-aent, it is crucial to adjust the chassis size as well. Failure to do so will result in the offline chassis size not being synced with the module. Make sure to configure the chassis size accordingly for proper functionality.
To enhance the performance of your 1734-AENT module, I suggest isolating it on a separate network from your automation system. Make sure to verify connectivity by pinging it, accessing the embedded web page via a browser, and checking the diagnostic page in RSLinx Classic. Additionally, consider power cycling the module to confirm proper retention of its IP address. Error code 0204 is typically a timeout issue, often caused by Ethernet network disconnections between the controller and the device. Ensure to inspect all network links and switches for potential faults. For compatibility, the 1734-AENT Series A firmware 3.012 should work seamlessly with a CompactLogix 1768 controller running v19 firmware and Rev4 firmware in the 1768-ENBT modules. Keep in mind that older firmware versions may trigger a 16#0203 error instead of 16#0204. When troubleshooting, it's essential to start with fundamentals like PING, HTTP, TCP Port 44818 connectivity using PowerShell TNC, and RSLinx Classic network browsing. If all these checks pass, proceed with troubleshooting the controller and firmware.
Robertmee mentioned the importance of setting the chassis size in the 1734-aent module after configuring the IP address. It is crucial to do this step separately as the offline chassis size does not automatically copy to the module. Make sure to assign the IP address first and then adjust the chassis size accordingly to ensure proper configuration.
From what you've described and the troubleshooting steps you've already taken, it seems like you have a very good grasp of the system. I would suggest checking the parameter settings once again - an incorrect subnet mask or gateway setting could cause the issue you're experiencing, despite the ping request being successful. On another note, is the flashing LED on your I/O module fast or slow? A fast flash might indicate an IP conflict with another device on your network. As a last resort, you might want to consider testing the module in a stand-alone setup. If the issue persists, you might indeed be dealing with a faulty module. Good luck!
Hi there, sounds like quite an ordeal you're going through! One possible angle to consider is the I/O module firmware version you've updated to, which might be incompatible with the ControlLogix firmware version on your PLC. Just cross check the compatibility lists to be sure. Also, a red flag for me is that you're not able to view parameters on the Internet page even though you're getting successful pings. This could potentially indicate a network interface issue on the I/O module. I suggest swapping the 1734-AENT module with a known working one, if you have one available, just to be sure. If the issue persists, it may be worthwhile to contact the manufacturer's tech support directly. Good luck, and keep us posted!
Based on your troubleshooting steps, it seems like you've really covered all the bases. One potential issue could be mismatched revision numbers between your hardware and the version your program uses for I/O configuration. RSLogix sometimes struggles to correctly identify hardware when there's a large discrepancy. I suggest double-checking the revision number in your I/O configuration to ensure it matches your physical module. Also, ensure you've got the right EDS file for the 1734-AENT. If these suggestions don't help, you might be dealing with a faulty module; perhaps consider replacing it to see if it resolves the issue.
