Function and Working Principle
The IC697RCM711 operates as a communication component within a redundant Series 90-70 PLC architecture. Its primary purpose is to support the exchange of information required for redundant controller coordination and reliable system operation.
A simplified architecture can be represented as:
Primary PLC System
↓
IC697RCM711
↓
Redundancy / Communication Interface
↓
Secondary or Redundant PLC System
↓
Industrial I/O and Field Equipment
Depending on the overall system configuration, redundancy-related communication allows the control system to maintain awareness of controller status and coordinate operation between redundant components.
Main Functions
The module can support important system-level functions such as:
- Redundant controller communication
- System status coordination
- Redundancy management
- Control system availability
- Communication between redundant system elements
- PLC system diagnostics
- Reliable data exchange
- Industrial control system integration
The exact role of the module depends on the Series 90-70 redundancy architecture and the associated CPU, rack, communication, and I/O configuration.
Role in Industrial Control Systems
High-availability PLC systems are commonly used when an unexpected controller failure could result in significant production losses or operational problems.
A typical redundant control architecture can be illustrated as:
Primary Control System
↓
Redundant Communication Infrastructure
↓
Remote / Distributed I/O
↓
Field Sensors and Actuators
At the same time, a secondary control system remains available to support continuity when required by the system design.
The IC697RCM711 contributes to this architecture by providing the communication functionality necessary for redundant system coordination.
This makes the module particularly valuable in applications where:
- Continuous operation is required
- Controller downtime is costly
- Process interruption must be minimized
- Redundant control architecture is implemented
- System diagnostics are important
- Reliable communication is required
Industrial Applications

Process industries often require continuous PLC operation because stopping a production process can cause material losses, equipment damage, or lengthy restart procedures.
The IC697RCM711 can form part of redundant Series 90-70 control systems used for:
- Process monitoring
- Pump control
- Valve control
- Batch processing
- Continuous production systems
Manufacturing Automation
Manufacturing plants can use redundant PLC architectures for production equipment where controller availability is critical.
Typical applications include:
- Automated assembly lines
- Production machinery
- Conveyor systems
- Material handling
- Packaging systems
- Automated inspection equipment
Redundant controller architectures can help reduce production interruptions caused by control-system failures.
Water and Wastewater Treatment
Water treatment facilities frequently operate pumps, valves, filtration equipment, and chemical dosing systems continuously.
A redundant PLC architecture can provide additional control-system availability for:
- Pump stations
- Filtration systems
- Water distribution
- Wastewater treatment
- Chemical dosing
- Aeration systems
The IC697RCM711 can therefore be incorporated into Series 90-70 control architectures where dependable controller communication is required.
