Machine speed calculation
Hello,
i need to convert high speed counter incremental value into machine speed(meter per minute) . i use a AC500 eco plc with onboard fast counter connected to a 1024ppr incremental encoder. Is there any function block to sample incrementing value ? Any help is appreciated.

Hope you are using ONB_IO_CNT.
For incremental encoder, the possible modes have to be defined in HW configuration for channel 0, depending of selected mode sometimes required channel 1 also.
Usually I create the logic in the application trough the inputs of ONB_IO_CNT and receive the speed of rotation in rpm. Depending on that speed you should calculate the machine speed in m/min
