FCP280 RH924WA Fiber Optic Network Adapter FOXBORO

Description

These 2-position baseplates support a non-fault-tolerant single or fault-tolerant pair of FCP280s, as well as two copper (RH924UQ) or fiber (RH924WA) adapters, required for connection to the Control Network. The FCP280 baseplate provides support for four HDLC fieldbuses (PIO channels). On the standard baseplates, Fieldbus port 1 can be terminated, if needed, by the DIP switches provided on the baseplate. Fieldbus ports 2-4 are internally terminated in the FCP280 baseplates and no external hardware or switches are required for their termination. All four Fieldbus port pairs (A/B) on the dual cable baseplate are internally terminated by default without the use of DIP switches. The FCP280 baseplates can be added in the field to existing or new configurations. The standard FCP280 baseplates have similar dimensions as the FCP270 2-position baseplates for ease of replacement, while the dual cable baseplates are larger and wider. When upgrading existing CP60 systems to use FCP280s, you can recover an additional two FBM positions after removing the old FCM10E/FCM10Efs.

Since the birth of PLC, it has been occupying the core position of the entire automation control system. Discussions about the development direction of PLC are often ongoing, whether it has been predicted since 10 years ago that PAC will replace PLC or even during this period that PLC is no longer needed in the future Industry 4.0 era.

So what kind of PLC do we need for the current global transformation period where intelligent manufacturing is being vigorously deployed? Especially known as the “pearl on the crown” – what will be the characteristics of medium and large PLCs?
Firstly, it needs to be clarified that the high-end PLC we are talking about now is no longer the same as 10 or even 5 years ago. It’s not that it was a high-end PLC 10 years ago, but now it can still be called a high-end PLC. Because society is developing and more advanced things have emerged, the standards for judging the so-called high-end are different in different periods.

In the current era of intelligent manufacturing, the following five major features have become essential conditions for high-end PLCs:
1. Pointing ability is no longer critical, communication ability is more important
Now everyone can see that the control system architecture has been fully industrialized through Ethernet. When fieldbus emerged more than a decade ago, we said that a high-end PLC should have distributed control capabilities, be able to carry many distributed sites, and have the ability to connect to fieldbus. At that time, when evaluating the performance indicators of a controller, the ability to take control was the most important aspect. With the improvement of on-site equipment intelligence and the need for control systems to ensure reliability, stability, and availability, the CPU’s point-to-point capability is no longer the key to distinguishing between high-end and non high-end. The focus now should be on the coverage ability of Ethernet communication on site, which directly determines the system’s level of control over on-site process equipment. At the same time, because we are currently in a transitional period, such as when the fieldbus is still in use, it cannot be said that due to the upgrade, it is no longer compatible with the past fieldbus. But the future development trend is the world of Ethernet, and support for Ethernet should be more important, and compatibility with existing fieldbus protocols is also an aspect that cannot be ignored.
Previously, Ethernet was a communication method used only between PLC and upper management computer software. Its advantage was that it could transmit a larger amount of data and have more control stations connected to this network. However, for on-site control, no matter how many I/O stations or devices there are, the communication volume is not as large as between the PLC and the upper computer. However, it has higher requirements for real-time and reliability, and packet loss rate is important. Real time and data transmission verifiability are also important.

With the development of lean management in factories, more and more factories are using upper level operation and maintenance management software such as MES systems and asset management systems. Of course, some people also refer to it as intelligent manufacturing or digital factories. This is because more and more process customers are pursuing more lean control, hoping to directly use PLC systems to retrieve some on-site data, improve efficiency and real-time performance, and thus enhance overall operational efficiency and management capabilities.
