SLC processor using the Input and Output Image files.
Read the Module’s Configuration from the SLC Processor
IMPORTANT
The interface module can be in software Run or
software Configuration mode during the read
operation.
With the SLC processor you The interface module then
1. Set the Read or Write bit to
indicate a configuration read
operation (O:e.0/13).
2. Set the Data ID value for the
configuration parameters to be
read (O:e.0/0...3).
3. Set the Data Handshake bit to
indicate the data in the Output
Image file is valid (O:e.0/14).
4. Interprets the Data ID value.
5. Gets the configuration data from
the Interface Module.
6. Loads the data into the Input
Image file (I:e.1...7).
7. Sets the Data Handshake bit to
indicate the image data is valid
(I:e.0/14).
8. Read configuration data.
9. 9. Reset the Data Handshake bit
(O:e.0/14).
10. 10. Resets the Data Handshake
bit (I:e.0/14).
