Overview
The MKY44-IO32A is a CUnet station IC with intelligent DIO control function. The MKY44-IO32A has the two modes of DIO
mode and PWM & Up/Down counter mode. Switching between the modes is achieved through hardware pin settings. Because a
The DOSA
(Data Output Station Address) pin of the ST44SW connected to the MKY44-IO32A is used to specify the network address of the
Furthermore, this control data is automatically copied to all CUnet ICs through CUnet communication (memory sharing). Input
data (DI) is automatically input to the MKY44-IO32A's own memory and automatically copied to all CUnet ICs through CUnet
communication (memory sharing). Existing users of CUnet can ge
t to
their networks in DIO mode. In addition, PWM, Up/Down counter mode provides an easy method for counter input and PWM output
control. New users have the opportunity for easy, intelligent DIO control without load on the CPU.
