CJ2M Slow USB?

[Paulo Ferreira 0]

Transferring a small CSV file from a memory card that is inserted in a CJ2M to a folder in the PC via USB takes a long time (400kb in more or less 1.5 min). Obviously it doesn't take that long when copying the file from a normal memory card reader. Is it normal to be this slow? Is USB slower than it should be, the compact flash is of bad quality or is it just a setting I need to change like configuring the baud rate in a RS232? Thanks.

Servicing time is allocated to Special I/O Units, CPU Bus Units, the peripheral USB port, serial ports, file access, and communications ports. If servicing is separated over many cycles, delaying completion of the servicing, set the same allocated time (same time for all services) rather than a percentage under execute time settings in the PLC Setup.
