Product Details

C718 AE101 HIEE300936R0101 Product Description

The ABB C718 AE101 (HIEE300936R0101) is the central processing node of the ABB AC 800M distributed control system, engineered to deliver deterministic real-time control across multi-layer industrial automation architectures. Its value is not realized in isolation — it is realized through tight system integration across every functional layer of the control cabinet and plant network.

At the control layer, the C718 AE101 executes IEC 61131-3 control programs with cycle times configurable from 1 ms to several seconds, enabling precise loop control for both discrete and continuous process applications. When deployed in a redundant pair configuration, a secondary C718 AE101 module mirrors the primary in hot-standby mode, ensuring bumpless transfer with zero process interruption upon primary failure — a critical requirement in power generation, refining, and chemical processing environments.

At the power layer, the controller relies on ABB PM856 or PM861 power supply modules to deliver stable 24 V DC to the backplane. These power modules support redundant power feed configurations, and their health status is continuously monitored by the AC 800M system, enabling predictive maintenance alerts before a power fault can propagate to the control layer.

At the I/O layer, the C718 AE101 communicates with ABB S800 I/O modules — including AI810 analog input, AO810 analog output, DI810 digital input, and DO810 digital output modules — via the ModuleBus protocol through a TB820 ModuleBus Modem. This architecture supports distributed I/O placement across the plant floor, reducing field wiring costs while maintaining high-speed, deterministic signal acquisition. Signal isolation is maintained at the I/O module level, protecting the controller from field-side transients and ground loops common in heavy industrial environments.

At the communication layer, the C718 AE101 supports PROFIBUS-DP for field device integration (drives, valve positioners, smart transmitters), Ethernet TCP/IP for supervisory connectivity, and MMS/IEC 61850 for substation automation applications. The CI854 PROFIBUS communication interface module and CI857 HART communication interface extend the controller's reach to legacy field instruments without requiring hardware replacement, protecting existing capital investment while enabling digital diagnostics.

At the HMI layer, the AC 800M controller integrates natively with ABB's 800xA System (System 800xA), providing operators with a unified process visualization environment. The 800xA platform aggregates data from multiple C718 AE101 controllers across a plant-wide OPC DA/UA server, enabling centralized alarm management, trend analysis, and batch reporting. For standalone panel applications, ABB PP865 or PP886 operator panels can be connected directly via Ethernet for local HMI functionality.

At the execution layer, the controller coordinates with ABB ACS880 or ACS580 variable frequency drives via PROFIBUS-DP or Ethernet/IP, enabling closed-loop speed and torque control for pumps, compressors, fans, and conveyors. Drive status, fault codes, and energy consumption data are fed back to the C718 AE101 in real time, supporting both process optimization and predictive maintenance workflows.

At the protection layer, the C718 AE101 interfaces with safety-rated I/O modules and external safety relays to implement emergency shutdown (ESD) logic. While the standard AC 800M platform is not SIL-rated, it is commonly deployed alongside ABB's AC 800M HI (High Integrity) safety controller in architectures where the standard controller handles regulatory control and the safety controller handles SIL 2/3 protection functions — a proven split-architecture approach in oil and gas and chemical processing facilities.

At the maintenance layer, ABB's Control Builder M engineering software provides full online diagnostics, force functions, and program download capabilities without process interruption. The C718 AE101's built-in diagnostic registers expose CPU load, memory utilization, communication error counters, and module health status — all accessible remotely via the 800xA asset monitoring framework, reducing the need for on-site maintenance visits and supporting long-term operational efficiency.

Power Generation & Utilities: In combined-cycle power plants and hydroelectric facilities, the C718 AE101 manages turbine governor control, boiler feedwater regulation, and generator excitation sequencing. Its hot-standby redundancy ensures continuous operation during planned maintenance windows, while PROFIBUS-DP connectivity integrates with ABB REF615 protection relays and ABB SACE Emax circuit breakers for coordinated protection and control.

Oil, Gas & Petrochemical: Upstream and midstream facilities deploy the AC 800M platform for wellhead control, pipeline SCADA integration, and compressor station automation. The C718 AE101's ability to handle both analog PID loops and high-speed digital interlocks within a single controller reduces panel footprint and simplifies engineering in hazardous area installations. Integration with ABB's Asset Health Center enables remote condition monitoring of rotating equipment across geographically distributed sites.

Water & Wastewater Treatment: Municipal water authorities use the AC 800M system for pump station automation, chemical dosing control, and SCADA integration across distributed treatment facilities. The C718 AE101's Ethernet connectivity supports seamless integration with SCADA platforms via OPC UA, while its low power consumption and wide operating temperature range make it suitable for unmanned remote pump stations.

Mining & Minerals Processing: In ore processing and flotation circuits, the C718 AE101 manages multi-loop density, flow, and level control with tight scan cycle requirements. Its ModuleBus I/O architecture supports high channel-count installations typical of concentrator plants, while PROFIBUS-DP integration with ABB ACS880 drives enables coordinated conveyor and mill drive control.

Pulp, Paper & Packaging: Continuous process lines in pulp and paper mills require sub-100 ms control cycle times for sheet tension, moisture, and caliper control. The C718 AE101's real-time multitasking OS supports concurrent execution of fast regulatory loops and slower supervisory logic within a single controller, reducing hardware complexity and improving system coherence across the production line.

Q1: Is the ABB C718 AE101 (HIEE300936R0101) compatible with existing AC 800M backplanes and S800 I/O modules already installed in my plant? Yes. The C718 AE101 is fully compatible with the AC 800M hardware family, including TB820 ModuleBus Modem backplanes and all S800 I/O modules (AI810, AO810, DI810, DO810, and specialty modules). It supports hot-swap replacement in redundant configurations, allowing module exchange without process shutdown. Firmware compatibility should be verified against your installed Control Builder M version prior to deployment; our technical team can assist with version matching as part of the pre-shipment verification process.

Q2: Can the C718 AE101 be integrated into a redundant CPU architecture, and what is the failover behavior? Yes. The AC 800M platform supports hot-standby CPU redundancy using two C718 AE101 modules configured as primary and secondary. The secondary controller continuously mirrors the primary's memory state via a dedicated redundancy link. Upon primary failure, failover is bumpless — the secondary assumes control within one scan cycle with no process bump or output disturbance. This architecture is validated for use in continuous process industries where unplanned shutdowns carry significant safety and economic consequences.

Q3: What does the 12-Month Warranty cover, and what pre-shipment testing is performed on the C718 AE101? Every C718 AE101 unit supplied by NANKMOS is covered by a 12-Month Warranty against hardware defects and functional failure from the date of shipment. Prior to dispatch, each unit undergoes a full functional verification test including power-on self-test (POST), communication port validation, memory integrity check, and I/O bus communication verification. Units that do not pass all test criteria are quarantined and not shipped. Warranty claims are processed with a target response time of 48 hours, and replacement units are dispatched from in-stock inventory to minimize your downtime exposure.
