VMIVME-7807 VMIVME-017807-413000 350-0001007807-413000 D is an important goal pursued by Japanese PLC systems. Due to the current PLC CPU module competition using 32-bit RISC chip, computing speed greatly improved. General basic instruction execution speed are up to tens of nanoseconds (ns), such as Mitsubishi Electric’s Q02HCPU its input instruction execution time of 34ns, Fuji Electric MICREX-SX series SPH300 up to 20ns, Yokogawa Electric’s FA-M3 series of F3SP59-7S its input instruction execution time of 17.5ns.
The execution time of VMIVME-7807 VMIVME-017807-413000 350-0001007807-413000 D does not give a complete picture. JEMA (Japan Electrical Manufacturers Association) has been advocating the use of the PCmix value (i.e., the PLC’s processing time performance indicator, which is expressed as the average number of basic instructions and data processing instructions executed in 1 microsecond) as a measure of the PLC’s computing speed. The so-called average number of basic instructions and data processing instructions executed in 1 microsecond is calculated as the statistical average of the frequency of instructions used by the PLC application.
