Is it possible to conduct online programming using a computer connected via a 1761 NET-ENI to the serial port on an SLC 5/03 PLC? The existing DH485 connection has proven to be unreliable with a new DELL computer.
Certainly! In addition, you may want to explore the 1747-UIC USB to DH485 converter for enhanced connectivity and communication.
Tom Hemeon asked if it is possible to conduct online programming using a computer connected to a SLC 5/03 through a 1761 NET-ENI on the serial port. The current DH485 connection has proven to be unreliable with a new DELL laptop. After establishing the connection, the ENI module is visible on Linx but not the PLC. The serial light on the ENI module is flashing, but the PLC light is not. When the AP00 cable is removed from the PLC and a serial cable is connected, it causes the laptop to hang and requires a reboot to see the PLC again. All devices - Laptop, ENI module, and PLC - are set at 19200. Does anyone have any suggestions or ideas on resolving this issue?

In my experience, it is recommended to utilize the AB_ETH driver instead of the AB_ETHIP driver in RSLinx for optimal performance. When using the ETHIP driver, only the ENI module may be visible, whereas the ETH driver allows you to view the PLC directly - which is typically preferable. This has been observed with Micrologix and should also apply to SLC models.
At first, I believed that was the issue as well, but it appears to be consistent no matter what.
Yes, it's possible to conduct online programming with a setup like that. However, you might run into some challenges due to differences in transmission speeds and communication protocols between the 1761 NET-ENI and the SLC 5/03. To mitigate these issues, make sure your drivers are up to date and consider using a communication interface module that is designed to work seamlessly with these devices. Alternatively, consider replacing the dated SLC 5/03 with a newer generation PLC, if that's feasible, to avoid these types of compatibility issues in the future.
Yes, it is possible to conduct online programming through that setup, but it may not be the easiest or most efficient choice. You see, a 1761 NET-ENI module's primary purpose is Ethernet communication to devices over DH485, not serial communication with an SLC 5/03. Considering your difficulty with the DH485 connection, however, you might want to troubleshoot that connection problem first or better yet, consider using an Ethernet to serial adapter or a USB-to-serial converter for a more stable connection to your SLC 5/03. It's also essential to ensure that your new DELL computer's COM port settings match the ones required for communicating with your PLC.
Yes, it's definitely possible to conduct online programming with an SLC 5/03 using a 1761 NET-ENI; it essentially converts Ethernet to DH+ which can interface with the PLC’s programming port. Just make sure the network settings are correctly configured and that your programming software is compatible. It might also be worth checking the cable and port settings on your new DELL computer since sometimes driver issues can cause connectivity problems. This setup could improve your reliability issues compared to the old DH485 connection.
Yes, it's definitely possible to conduct online programming through a 1761 NET-ENI to access the SLC 5/03, and it might actually improve your connection stability compared to DH485, especially if the newer Dell has compatibility issues. Just make sure that you properly configure the NET-ENI and use the right settings in your programming software. Also, keep in mind that the initial setup might require some troubleshooting, but it can be worth it for a more reliable connection!
