Remote field devices (I/O devices such as signal modules but also HMI operator devices) can be integrated directly or via so-called IO controllers into the Industrial Ethernet (PROFINET IO). Together with WinCC flexible 2005 SP1, SIMATIC HMI operator devices of the 177 series and 277 series classes support PROFINET IO. With it, time-critical operations - as carried out with the DP direct keys via PROFIBUS - are now also possible on the basis of Industrial Ethernet. This concerns the direct keys with panels ranging from the OP/TP 177B up to the Multi Panel MP 277 as well as the direct keys and the hand wheel with the Mobile Panels 177 and 277, each in the model for PROFINET use. In parallel to this, the "regular" communication with the process of course still takes place (tag values, alarms). Diagnostics alarms on PROFINET occur via "system error reporting" - for panels as well, since they are to be viewed as PROFINET IO devices.
