Distributed Discrete I/O (DDIO) and Combination I/O (DCIO) Module


A half-day course to provide instruction on the simple and advanced configuration of the DDIO/DCIO module and the various hardware connections. The web-based online DDIO/ DCIO module configuration tool will be discussed and used throughout the course. Laboratory exercises will compliment the lecture material, allowing each student to modify a DDIO/ DCIO configuration, transfer it from the DDIO/DCIO module (for documentation and replication purposes), make the configuration active, and then monitor the functionality of the DDIO/DCIO module running the configuration.


Understanding of substation operations and apparatus. Understanding of the data provided by substation apparatus. Understanding of IRIG-B and time stamping preferred. Familiar with using a PC, setting IP addresses, use of terminal emulators, browsers, etc.
