TOPDOC PLC-2 includes includes offline program development, upload/download, program documentation and reports, and online programming/ monitoring/ troubleshooting. The package includes our custom "Attached Mode" cable (Cat TD2-UCAM) that connects from a PC's USB port to the PLC-2 front port.  No special interface card is needed in your PC!  Online programming, upload/download and forcing are supported when connected to the PLC-2 via this cable.

Although TOPDOC PLC-2 is a DOS application, we have packaged it so it can be used on most modern Windows PC's. You don't need to worry about finding an old O/S, setting up partitions, etc.  All you need is an available USB port for the Attached Mode Cable when doing online operations.
