Unit cycle time Input words are allocated in the PLCs CIO area as Basic I/O Unit, i.e. sequentially starting at the leftmost unit. See CJ1-series Operation Manual W393 for details. The internal processing time for all measurements by the unit is determined by the number of active channels and the filter type. Create the I/O table in the PLC after changing the switch settings, to register the correct number of input words in the PLC CPU. The unit is registered as 48-point, 64-point, or 96-point input unit, depending on the Unit initialisation number of 16-bit CIO words it occupies.
