1. Make sure that the Address field in the
I/O Device form is valid and that the Windows user that is
launching the Citect runtime has full read/write privileges to that
location
2. Run the Computer Setup Wizard and make sure that the correct
project is selected and that the computer role is set to 'Server
and Display Client' (or 'Server and Control Client in v7.10 and
above).
3. If the above steps do not help, the Disk I/O Device storage file
may have been corrupted. Usually, this will result in a file with a
0Kb size. You will need shutdown the Citect runtime, delete the
existing file and then restart the Citect runtime so that a new one
is created. To locate the Disk I/O Device storage file, refer to
the Address file in the I/O Devices form for the path. For example,
if the address field shows [RUN]:IODev.CDK then you
need to delete the IODev.CDK file located in the main project
directory (refer to [CtEdit]Run parameter in citect.ini file for
full location). |
