More Information

Overview Manuals Control Architecture Migration Planning Commissioning Application
  • Confirm RH924YA on the processor label before replacing an FCP280
  • Match the installed FCP280 baseplate and network-adapter media
  • Preserve the controller database, role and PIO mapping before removal

Foxboro RH924YA is the exact processor-module part number for the FCP280 control platform.

It installs in a dedicated FCP280 baseplate and can be deployed singly or as one member of a fault-tolerant pair.

Before installation, confirm the baseplate, copper or fiber adapters, software image, database sizing, letterbug, fieldbus loading and primary/shadow role.

Availability, condition, price, and shipping time for RH924YA are confirmed during quotation.

  • The processor executes regulatory, logic, timing and sequential control
  • Single and fault-tolerant configurations use dedicated FCP280 baseplates
  • Four PIO channels connect supported 100 and 200 Series field modules
  • Controller and fieldbus loading must be sized before migration
  • Baseplate type and network adapters must match the installation
  • Database, letterbug and time-source configuration must be preserved
  • Verify primary/shadow role and network-adapter health
  • Confirm every PIO channel and attached baseplate chain
  • Prove control execution, synchronization and recovery under controlled conditions
  • Distributed regulatory and sequential process control
  • Fault-tolerant control using a paired FCP280 configuration
  • Migration control for supported 100 and 200 Series field I/O
Description
Foxboro RH924YA executes process control blocks and communicates with supported field modules over four HDLC PIO channels.

When paired on the appropriate baseplate, two RH924YA modules continuously synchronize and compare control activity to provide fault-tolerant operation.

The module is used in new or migrated Foxboro DCS control stations where processor performance, distributed I/O and controlled redundancy are required.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is the baseplate included with Foxboro FCP280 RH924YA?
No. Foxboro FCP280 RH924YA is the processor module. The compatible horizontal, vertical or dual-cable baseplate and the required copper or fiber network adapters must be confirmed separately in the quotation.
Can Foxboro FCP280 RH924YA directly replace an FCP270?
Do not assume a direct replacement. Confirm the installed Foxboro DCS release, control-database size, processor image, baseplate, network adapters, fieldbus architecture and the documented migration procedure.
Can a second Foxboro FCP280 RH924YA be added later to create a fault-tolerant pair?
Only when the installed baseplate supports the fault-tolerant arrangement and both Foxboro FCP280 RH924YA modules have compatible hardware, firmware, processor images, network adapters and database configuration.
Why can Foxboro FCP280 RH924YA start but fail to detect some field modules?
Check the PIO cabling, fieldbus speed, splitters and terminators, baseplate-chain arrangement, FBM addressing and power. Also confirm that the restored control database matches the physical I/O topology.
What software compatibility must be confirmed before installing Foxboro FCP280 RH924YA?
Confirm the installed Foxboro DCS release, approved FCP280 processor image, database tools and any migration or online-image-upgrade requirements. The replacement must match the software level supported by the operating system.
What information should be backed up before replacing Foxboro FCP280 RH924YA?
Save the control database, processor image and revision, letterbug, processor role, network paths, PIO topology, time-source settings, sizing report, alarm state and current diagnostic records.
What commissioning checks are required after installing Foxboro FCP280 RH924YA?
Verify the processor role, both control-network paths, every PIO channel, connected FBMs, control-block execution, time synchronization and alarms. For a fault-tolerant pair, also perform a controlled role-transfer and restart-recovery test.
