  • Floating point math coprocessor dedicated to floating point and process control operations
  • Autotuning PID with 2 degrees of freedom (responds to both set value and disturbance)
  • Compensation functions to allow loop modeling closer to the actual process
  • Process alarm functions related to high, low and deviation process and manipulated variable values
  • Tracking functions to allow smooth transfer between manual and automated control
  • Hot swappable modules
  • Increased functionality in Version C or later (S/N 07032x)

MELSEC Q Series Redundant CPUs

These CPUs take the process control capabilities of the Q Series process CPUs and add full hot-backup capability by using dual redundant CPUs. Use this system in applications where downtime cannot be tolerated for reasons of safety, equipment damage, financial loss, interruption of service, or regulatory compliance.

Key Features:

  • Prevent controller downtime with dual redundant CPUs (control and back-up). Any failure of the control CPU causes immediate transfer of control to the back-up, preventing system failure or interruption.
  • Synchronize up to 100,000 words of process data between CPUs per scan
  • Switchover time typically around 40ms, insuring “bumpless” transfer
  • CPUs reside on physically separate racks, allowing control CPU to be replaced while back-up maintains system operation
  • Low cost of ownership; most parts are interchangeable with standard Q Series systems
  • Redundant power supply option
  • Redundant MELSECNET/H control level network provides link to I/O stations at up to 25Mbit/s
  • Over 50 process control related instructions (same as Q Process CPUs)
  • Most I/O may be hot swapped
  • Increased functionality in Version D or later (S/N 07032x)
  • SFC active step comment readout instruction
  • Increased multiple CPU shared memory flexibility
  • 1/1000 second resolution timestamp capability
  • Store sampling trace data in Standard RAM
  • Power supply error detection function

B. MELSEC Q Series Base Units

The base unit (sometimes called a base rack) is the foundation of Q Series systems. All CPU modules are installed on it, along with a power supply, I/O and special function modules. Besides providing physical support to the component modules, the base unit enables communication and power distribution between modules. The base unit can either be directly bolted to a panel, or mounted via DIN rail. In the case of DIN rail mounting, the DIN rail Adapters must be used. Base units accommodate between 3 & 12 modules. For systems that require more modules than be accommodated on the base unit, an extension base unit is required. These connect to the base unit via extension cables.

MELSEC Q Series / iQ Extension Base Units and Connection Cables

Use extension base units (also known as extension racks) in systems that require more modules than can be accommodated on the main base unit. Extension base units are available with a slot for an additional power supply (Q6_B) or without (Q5_B). Use Q6_B extension bases in systems where the current supplied by the base unit power supply is insufficient for the whole system. Up to 7 extension base units may be connected to the base unit, allowing a total of 8 bases. The 8 base units may be extended over a distance of up to 13.2 m (43.28 ft). The maximum number of installed modules is 64. If your system requires more modules or greater distances, consider using a network to link the system together. See the network section for more details.
