3.19.4 RIO head stations
PCD3.RIOs (remote I/Os) are used to capture decentralized I/O signals. PCD3.RIOs
communicate with Profibus-DP or any SPS Master; the .gsd file is included in PG5
(version 1.2 or above), or it can be retrieved from www.sbc-support.ch.
The web server integrated into PCD3.RIOs offers the user great benefits in
commissioning, diagnostics and service. Access is via familiar easy-to-use standard
web browsers. This makes it easy to check the states of all I/O signals (digital/
analogue/counters), and to modify specific output states.
