A definite distinction between open load and short to ground is guaranteed by design.
The standard way of obtaining diagnostic information is as follows:
Clock in serial information into SI pin and wait approximately 150 µs to allow the outputs toset-
tle. Clock in the identical serial information once again - during this process the data coming
out at SO contains the bit combinations representing the diagnosis conditions as described in
figure 1.
By means of the control byte it is possible either to:
a) Serial Control of Outputs
Control byte is set to FFhex: Data byte will be accepted. The outputs will be switched ON or
OFF according to the information of the data byte and the parallel inputs (Channel 1 to 4 be-
cause of AND operation).
All other control words except the one for 'Diagnosis Only = 00hex' will also be accepted as a
valid control word and the data will be accepted.
Example: HLLHLHLH DDDDDDDD: Outputs will switch according to the data bits.
b) Diagnosis Only
Control byte is set to 00hex: Data byte will be ignored. Diagnostic information can be read out
at any time with no change of the switching conditions. Only 00hex means 'Diagnosis Only'.
