Introduction
Easy to operate and observe
The MP270 enables operating statuses, current process values and errors
concerning a connected PLC to be graphically displayed and the relevant machine
or system to be easily monitored and operated. Display and operation of the
MP270 can be adapted optimally for the respective process requirenments by
using the configuration software ProTool (from version 5.1).
The MP270 can be used to:
control and monitor the process by means of the menu system. Setpoint values
or control element settings, for instance, can be modified by entering values or
activating configured function keys;
display processes, machines and systems on fully-graphic, dynamic screens;
visualize operating and alarm messages and process tags, e.g. in output fields,
bar graphs, trend curves or status settings;
intervene directly in the running process by using the integrated keyboard.
Configuration using ProTool
Graphics, texts and operating and display elements which need to be represented
on the MP270 must first be created on a configuration computer (PC or PU) using
the configuration software ProTool. The configuration computer must be connected
to the MP270 in order to download the configuration data to the MP270 (refer to
"Configuration phase" in Figure 1-1).
Once the configuration has been successfully downloaded, connect the MP270 to
the PLC. The MP270 can then communicate with the PLC and respond according
to the information configured for running the program in the PLC (refer to "Process
control phase" in Figure 1-1).
