Position in the SIMATIC HMI environment
The HMI devices were designed for the middle performance range. They meet the demands
placed on performance, display possibilities and price/performance ratio. In addition, they
extend the communication potential of the office world. Customer needs and requests were
taken into account in respect to extending data transfer functions, simplifying operation, and
increasing acceptance when compared with Windows CE units.
The HMI devices not only support the classic HMI applications (visualization with WinCC
flexible) but also additional applications, such as process diagnostics (ProAgent).
1.2 Field of Application
Overview
The HMI device allows graphic display of operating statuses, current process data and errors
of connected PLCs. The user can operate and observe the machine or system being
monitored easily using the HMI device.
Applicable areas of use include machine and apparatus construction sectors, printing and
packing industries, automobile and electrical industries and chemical and pharmaceutical
industries.
The high degree of protection (IP65 on the front side) and avoidance of moving storage
media, such as hard disks and floppy disks, ensure that the HMI device is suitable for use in
rough industrial environments and on site where a machine is located.
Possible installation locations for the HMI device:
• Switching cabinets/consoles
• 19" cabinets/racks (keyboard units)
Connection options for external peripherals (keyboard, mouse and printer) via a USB port,
for example, and the possible use of CF and PC cards support multifunctionality. Due to the
fact that the HMI device is equipped with high performance basic hardware and has a
minimum installation depth means that it fulfills all the requirements for operation in the
vicinity of the machine.
The HMI device can be used to:
• Operate and monitor the process using the menu system. Setpoint values or control
element settings can be modified by entering values or activating configured softkeys
• Display processes, machines and systems on full-graphic, dynamic screens
• Display and process alarms and tags through output fields, bar graphs or trend curves
• Use input to intervene directly in the running process
