14.9.1
Functionality
M14790-3 v5
The IED provides two function blocks enabling several IEDs to send and receive
signals via the interbay bus. The sending function block, MULTICMDSND, takes
16 binary inputs. LON enables these to be transmitted to the equivalent receiving
function block, MULTICMDRCV, which has 16 binary outputs.

14.9.2.1
General
M14792-3 v3
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
outputs.
•
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.
