Seriplex - what is it ?
•
The SERIPLEX control bus is a component-level network technology providing a fast,
simple, distributed I/O system to exchange data amongcontrol or manufacturing
process elements. Within each SERIPLEX controlbus device is an application-specific
integrated circuit (ASIC) that enables communication between the SERIPLEX control
bus and the component I/O. SERIPLEX devices are networked together by a single,
shielded, five-conductor cable.
•
The control bus is designed to complement rather than compete with the higher-level,
field bus-type communication systems that are best suited to transmitting large
information data packets. SERIPLEX protocol resides primarily at the physical device
level, providing the deterministic, process-critical, real-time I/O updates needed by
most control systems and leaves slower, higher-level communication to other networks.
Seriplex – abilities
•
SERIPLEX devices can control photo switches, proximity sensors, push buttons, and
actuators, such as valves and contactors. A SERIPLEX device receives its commands
from controllers such as PLCs and personal computers. Universal discrete I/O modules
connect the control bus with non-SERIPLEX devices. The SERIPLEX ASIC can also
be embedded into I/O devices or machinery for direct connection to the SERIPLEX
control bus.
