l The data outputs of the BCD decade switch must be decoupled via diodes. If necessary, use a
terminal extension (via system bus CAN).
– LENZE offers this terminal extension.
Function
A BCD is transmitted to the target code as follows:
Input/output Signal Function
BCDx−SELx or
BCDx−SIGN HIGH Triggers the corresponding BCD decade switch. Reading and temporary storing of the BCD data
to BCDx−DATA1 ... BCDx−DATA4.
BCDx−LOAD LOW−HIGH edge Writes BCD data to the target code.
