The configuration data for the interface module consists of a string containing a mixture of numbers and characters. The Application PCS45 creates and manages a copy of this data string in the computer and controls the exchange of this data between the hard drive or disk and/or the module. The data flow between the copies of this data structure depends upon the operation mode.
The various displays within the application enable the contents of these data structures to be viewed and altered. After a change has been made and accepted the data values are tested before the data is transferred to the data structure.
A copy of the configuration data held in the software can be saved into or accepted from a file at any time, but the operation mode will always change to Offline. In the Offline mode no data is automatically transferred between the software and the temperature converter or other interface module.
When changes have been accepted in the Online operation mode, data is transmitted straight into the non-volatile memory of the module. If there are any errors during this data transfer the operation mode changes to Offline because coherent configurations cannot be expected.
In the demo mode, data is not transferred to the module but transferred to another memory area in the PC and any exchange is simulated.
