Process CPU module SIL2 process CPU module Redundant function module

The process CPU modules are highly flexible according to process applications from simple loop control to complicated loop control. Initial and maintenance costs can be reduced by replacing a highly-specialized distributed control system (DCS) with a process programmable controller. When paired with the redundant function module, a highly reliable redundant control system is realized.

Interface

Features^{DCS style features in a cost-efficient automation control system}

• Extensive process instructions
• Max. 300 control loops
• Low cost

• The process control system enables execution of dedicated process instructions (such as two-degree-of-freedom PID, sample PI, and auto-tuning) and large-scale process control with a maximum of 300 loops
• Low-cost automation system equal to DCS capabilities without the financial burden is realized

Redundant system flexible installation

• Extendable to 550 m
• Flexible system configuration

• Optical-fiber tracking cables enable the standby system to be installed in a remote location up to 550 m from the control (primary) system
• The control panel installation is easier with less constraints to cable length, allowing flexible system configuration

Fast system switching realizes highly reliable control

• Optical fiber cable
• Fast system switching
• Highly reliable

• The tracking cables are immune to noise interference and support fast data transfer rates
• System switching speed from the control system to standby system has also been improved to speeds of approximately 10 ms, further improving system reliability

Operation not interrupted even when an error occurs

• Single-point failure reduction
• Variety of redundant configuration
• Online replacement

• The redundant system can minimize the risk of singe-point failure in various redundant configurations which may vary depending on the use and the size of control system. Operation is not interrupted even when an error occurs
  • Redundant configuration consisting of the control (primary) and standby CPUs
  • Redundant extension cable with redundant extension base unit^*1
  • Redundant network configuration with a dual cable topology of CC-Link IE Field Network
  • Redundant remote head module (dual remote stations)
• Online replacement of cables and modules (hot-swapping) is possible while continuously operating the system when an error occurs, enabling prompt troubleshooting

• *1.Supported by the process CPU module (R□PCPU) only.

Efficient engineering through extensive compatibility between software and devices

• Efficient screen creation
• Highly scalable system
• Efficient engineering

• Screen creation is easier in an efficient engineering environment realized by the extensive compatibility between the engineering software GX Works3 together with SCADA software GENESIS64™, GT SoftGOT2000, and GOT2000
• Scalable SCADA control systems can be realized combining these products

Detect errors in connected devices and networks on each system

• Diagnostics of both systems in the redundant system
• Improved redundant system reliability

• An error in an external device or network of the systems (control system and standby system) can be detected by executing a program that diagnoses external devices or networks of both redundant systems.
