Function3denesthepreferredstateoftheoutputs.Thispreferredstateis
chosen when
● the connection to the bus is interrupted
● the master is in the STOP/PAUSE state
The status is 0 if the selection was accepted, otherwise it contains 0xFF.
Thecodingofthemodulespaceeldisthefollowing:
Bit Meaning
0…3 Module space (0…15)
4…6 Channel number (0…7) For analog outputs, this is the analogue
channel number
7 When set to (continue), the last status of the outputs is retained.
In which case bytes 0 and 1 are irrelevant.
Example:Moduleposition=0x82→Theoutputs(if16digitaloutputs,then
the 8 LSBs) of module position 2 (3rd place) are retained.
IntheeventofabuserrororinSTOPmode,thedefaultswitch-o󰀨
status sets all outputs to 0.
For analog outputs, this does not mean that the value of all outputs is 0.
