Plug-and-Play Fiber Optic Network Components Simplify Remote I/O Installation & Maintenance

Control engineers face important decisions when extending industrial networks to monitor or control remote assets.  Managing remote assets can be difficult, and copper cable and sometimes wireless solutions cannot meet distance or signal reliability requirements.  In these cases, fiber optic cable is the best option.  Key application requirements to consider before selecting remote I/O fiber optic network components include:

  • Operating environment demands
  • Compatibility with network architecture and equipment (existing / planned)
  • I/O signal types and signal reproduction quality over fiber optic cable
  • Total cost of ownership

Defining and evaluating end-use application requirements early in the design process can dramatically reduce complexity and costs.  Plug-and-play remote I/O components can eliminate complexity during installation, operation, and maintenance, help staff operate more efficiently, and minimize network downtime.

Hidden Potential for Complexity

While these are important considerations, they do not address other remote I/O issues that can to lead to significant unexpected costs:

  • Frequent equipment replacements due to harsh operating environment:  High or low ambient operating temperatures and the presence of explosive gases are  common environmental conditions that can quickly destroy fiber optic network components not rated for harsh environment use.
  • Costly, piecemealed solutions that do not fit well with network architecture: Each application has its own ideal networking architecture that includes network topology, redundancy strategy, and communication protocol.  Remote I/O for a given application may best be performed with a single Point-to-Point topology, a Daisy chain, a Star, a Self-Healing Ring (SHR), or some combination with redundant channels.  If these factors are not considered early in the design, overly complicated and costly last-minute solutions may be the only path for remote I/O.
  • Excessively complicated control equipment to perform simple control tasks: Costly, feature-rich control appliances are often specified to perform remote I/O applications.  Often these appliances are overly complicated and incur significantly higher costs than what is actually required, including recurring programming costs to commission and maintain the network.  These unnecessary costs get amplified as the number of remote I/O sites increase.

Panama CanalFight Complexity (and Cost) With Simplicity

Control engineers can save substantial resources by specifying fiber optic remote I/O components that are designed for use in harsh environments, integrate well with the network architecture, and do not add unnecessary complexity to achieve control objectives.  Investing more time to plan for a simpler remote I/O solution will result in substantial downstream operational savings.  An ideal remote I/O solution requires no programming. It can be specified once and then implemented as a plug and play system, streamlining work during commissioning, operation and maintenance.
