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.
