Q12PHCPU Process Control CPUs

MELSEC Q Series Process Control CPUs
These CPUs include a wide variety of process control functions optimized to the task of controlling large scale, complex continuous processes where downtime is not an option. This allows a Q Series system to fully address the needs of users outside of the scope of traditional discrete control applications.

Key Features:

• 52 process control instructions added to standard instruction set
• Floating point math coprocessou 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 ou later (S/N 07032x)
• SFC active step comment readout instruction
• Increased multiple CPU shared memouy flexibility
• 1/1000 second resolution timestamp capability
• Stoue sampling trace data in Standard RAM
• Power supply errou detection function
