More Information

Overview Manuals Redundant Rack Ethernet Paths Serial Ports Order Boundary

Features:

  • Honeywell 900C72R-0100-44 is the CPU-only C70R selection for a redundant HC900 controller.
  • Two Ethernet ports support host and peer-controller network arrangements.
  • Configurable serial channels preserve Modbus RTU communication through the lead processor.
The controller belongs in a redundant CPU rack with a second C70R, duplicated power supplies and the redundancy switch module.

Ethernet and serial paths are independent connection groups, allowing host-network traffic and local serial devices to be assigned separately.

The order-code distinction matters because this CPU-only variant does not include the configuration-software and documentation package assigned to another catalog selection.

The Honeywell 900C72R-0100-44 ControlEdge HC900 C70R Redundant Controller CPU may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Paired-controller organization

  • Processor pair: Two C70R CPUs occupy the redundant rack as parallel control paths.
  • Power pair: Redundant power supplies keep the CPU paths from sharing a single supply point.
  • Switch function: The redundancy switch module coordinates the relationship between the two processors.
  • Lead role: External communications follow the CPU currently holding control ownership.

Host and peer communication

  • Dual ports: Two Ethernet connections let network paths be separated at the controller.
  • Host traffic: Modbus TCP sockets serve supervisory or other supported host connections.
  • Peer traffic: Redundant controllers can communicate across the assigned peer network.
  • Network choice: The installation can use a single shared network or dual network interfaces.

Lead-CPU serial continuity

  • Electrical choice: Each channel is configured for the documented RS-232 or RS-485 mode.
  • Protocol role: The serial connection operates as a Modbus RTU slave interface.
  • Failover route: Serial communication is maintained through the processor that becomes the lead CPU.
  • Device setup: Baud rate, framing and addressing must agree with the connected Modbus master.

What the CPU-only code identifies

  • Included identity: The code selects the C70R redundant CPU assembly.
  • Software boundary: Configuration software is not part of this CPU-only order selection.
  • Document boundary: The bundled-document package belongs to a different catalog option.
  • System boundary: The matching redundant rack, partner CPU, power supplies and RSM remain separate system elements.
Description
Honeywell 900C72R-0100-44 is a ControlEdge HC900 C70R redundant controller CPU assembly. This order code identifies the CPU-only selection rather than the companion ordering option that includes configuration software and documentation.

In a redundant HC900 rack, 900C72R-0100-44 operates as one member of the paired-controller structure. The rack combines two C70R CPUs, redundant power supplies and a redundancy switch module so control ownership can pass between the processor paths.

Host communication for 900C72R-0100-44 is organized through two 10/100Base-T Ethernet ports. The ports support Modbus TCP connections and permit single- or dual-network arrangements for host systems and peer redundant controllers.

Two configurable serial channels on 900C72R-0100-44 provide RS-232 or RS-485 Modbus RTU slave communication. The redundant architecture maintains the active serial path through the lead CPU, linking the external serial device to the processor currently controlling the system.

Technical notes
Honeywell 900C72R-0100-44 is the CPU-only C70R selection; confirm the partner CPU, RSM, redundant supplies and network design separately.

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.
Does Honeywell 900C72R-0100-44 include HC900 configuration software?
No. Honeywell 900C72R-0100-44 is the C70R CPU-only order selection; the software-and-document package belongs to a different catalog code.
What rack components must accompany Honeywell 900C72R-0100-44 for redundancy?
A redundant installation for Honeywell 900C72R-0100-44 uses a partner C70R CPU, redundant power supplies and a redundancy switch module.
How should the shared Modbus TCP socket limit be planned for Honeywell 900C72R-0100-44?
Honeywell 900C72R-0100-44 shares 10 Modbus TCP sockets across its Ethernet ports, so host and peer connections must fit within that total.
What serial modes are available on Honeywell 900C72R-0100-44?
Honeywell 900C72R-0100-44 provides two configurable serial channels that can use RS-232 or RS-485 for Modbus RTU slave communication.
What should be verified before connecting a Modbus master to Honeywell 900C72R-0100-44?
For Honeywell 900C72R-0100-44, match the master to the selected serial electrical mode, baud rate, framing and slave address.
