Ratio controller with CEMAT V5 (SIMATIC PCS 7)

  • Entry
  • Associated product(s)

QUESTION:  
How do you realize a ratio controller with CEMAT V5?

ANSWER:  
CEMAT V5 includes two controller blocks ("TE_CTRL", "TE_VSLCT") from the PTE library, but no ratio controller.

In principle a ratio controller is nothing more than a multiplicator. This is why you can use the multiplicator block from the SIMATIC PCS 7 standard library for this.

This block can be found via "PCS 7 Library V52 > Templates / Blocks > MUL_R (FC63)".

MUL_R multiplies two REAL numbers by each other and outputs the result as a REAL number at the block output.
