Step 3: The MVI56-BAS copies the status code to input image word 1, low byte
(Local:x:I.Data[1]). After the transfer is done the MVI56-BAS sets the input image
word 0 bit 11 (Local:x:I.Data[0].11) to inform the CLX that the data was received .
Step 4: The CLX resets output image word 0 bit 11 (Local:x:O.Data[0].11).
Step 5: The MVI56-BAS resets input image word 0 bit 11 byte
(Local:x:I.Data[0].11)
The following ladder file shows an example of how to implement the procedure
described above when the destination file is a MSG instruction:
The MSG parameters are described below:
In case the destination file is the CLX input buffer, the ladder logic for CALL 122
is shown in the following example:
