: Version 8.10.00 was a significant update released around late 2008, introducing critical support for the MicroLogix 1400 controller and FRN 11 firmware for SLC modular controllers. rslogix 500 81000 cpr9 w master disk exclusive

RSLogix 500 relies on RSLinx to manage communications. If RSLinx has an active "Exclusive" driver connection open (e.g., via a DF1 serial cable or an Ethernet driver set to exclusive mode), RSLogix may be prevented from accessing the file handles required to open the project.
