  • Page 6: Before Using The Product

    The product is used in combination with the I/O controller module <CPU-CAxx(FIT)GY> or microcontroller unit <CPU-SBxx(FIT)GY> in the F&eIT Series. A single DIO-8D(FIT)GY module provides up to eight TTL-level I/O channels. (TTL 5-V type) By reading this manual carefully, please build a system by creating applications programs, setting the switches, and connecting the module to external devices.

  • Page 7: Functions

    [High(5V): 0, Low(0V): 1]. Output The Module writes a maximum of 8 points (<DIO-8D(FIT)GY>) of digital signals in groups of 8 points to an external device. Access to the Module from a controller module is performed through the output port that is specified by means of a Device ID. When data is written to the output port by the execution of an output command, the data is held on the latch circuit that is associated with the output port.
