HMI

Human machine interface (HMI)

The components of the level SIMATIC HMI (Human Machine Interface) serve as an interface between machine and user.  Functions, switches or process values are visualization on operator or touch panels.  With the help of this visualization, error messages or measured values for the user can be easily represented.  An optical detection of processes lightens operation to the user where he/she can quickly learn the external effects of his/her actions.

The Human Machine Interface is divided into 4 classes:

 

·            Push Button Panels (PP 7 and PP 17), the innovative alternative for conventional operation field

·            Text based displays OP 3, OP 7 and OP 17, for monitoring and operation in the machine range.

·            Graphic based displays OP 25, OP 37, TP 27 and TP 37, for comfortable monitoring and

operation in the machine range

·            Windows based systems like the OP 37 pro, the MP 370 or the MP 270 for operation in the

machine range.

 

The devices are configured with the configuration software Pro Tool that is available in three different performance variants suitable to device class.

 

The Human Machine Interfaces can be connected directly over MPI or PROFIBUS-DP to the automation systems.  With configured function switches, command buttons or display elements one can receive direct access to the CPU.
