What is the performance of the CX1000 ?
According to our measurements CX1000 is able to execute 1024 mixed PLC instruction in about 50 microseconds. These mixed instructions include integer and bit operation in various sizes as well as floating point instructions. For the NC operation, one can count on a base time consumption of 200ìs and add about 100ìs per each axis. For example a system with a configured NC task and two axes, a total of 200ìs + 2 x 100ìs = 400ìs is consumed for the operation of motion control. More detailed information and comparison may be found at http://www.pc-control.net/ in the pc-control magazines 2/2002 (look for “Customized Automation” article) and 2/2003 (look for “TwinCAT performance” article). Please look into the “archive” section of the online site of the Beckhoff pc-control magazine.
