Abstract
Output control circuit for a programmable logic controller, comprising a control unit (13) and a circuit (14) for controlling and checking output channels (11), including a deserializing section (16). The output circuit receives descending frames (T1) and ascending frames (T2) and, according to its configuration, it returns ascending frames (T3) to the control unit produced from frames (T1) and/or (T2).
