2 Functions of Devices in DVP-PLC Finding out the module which is disconnected or damaged in an EH system: Situation: A DVP-EH2/EH3 series MPU is powered, the ERROR LED indicator blinks, and the error code in D1004 is H’C41E. Reading the value in D1104: The value in D1104 indicates the GPIO which is damaged. It represents a GPIO number. (GPIOs are numbered from 0.) The number of GPIOs in an MPU or an extension module is described below.
