16 binary inputs. LON enables these to be transmitted to the equivalent receiving

function block, MULTICMDRCV, which has 16 binary outputs.

Design

The common behavior for all 16 outputs of the MULTICMDRCV is set to either of

two modes: Steady or Pulse.

1 = Steady: This mode simply forwards the received signals to the binary

2 = Pulse: When a received signal transitions from 0 (zero) to 1 (one), a pulse

with a duration of exactly one execution cycle is triggered on the

corresponding binary output. This means that no connected function block

may have a cycle time that is higher than the execution cycle time of the

particular MULTICMDRCV instance.
