Introduction

New product category

The SIMATIC Multi Panel MP270 belongs to the new product category called
“Multifunctional Platform” and is positioned in the product hierarchy between
classic components such as operator panels and PLC on the one hand, and
industrial computers on the other. The multifunctional platform combines the
robustness of the dedicated hardware solutions with the flexibility of the PC world.

The new product category combines functions, such as visualization and control,
based on the operating system MicrosoftR Windows R CE.

Multi Panels provide the following additional performance features as compared to
the proven SIMATIC operating units:

S Archiving process values and messages
S Dynamic use of screen objects (e.g. moving objects)
S Simulation of the configuration on the PC/PG
S Large selection of pre-finished screen objects available during configuration

(e.g. message view, Status/Force, buttons, selection fields)

S Creation of vector graphics in ProTool without the use of a graphic editor

Area of use of the MP270

The MP270 has been conceived for easy machine operation and monitoring. It
provides a realistic graphical representation of the machine or system to be
monitored. Its area of use includes implementation in machine and apparatus
construction as well as in the packing and electronics industry.

The high degree of protection (IP65 on the front side) and non-implementation of
moving storage media, such as hard disks and floppy disks, ensure the MP270 is
also suitable for use in rough industrial environments and directly on site on the
respective machine.

Installation locations for the MP270 include:

S Panels/Consoles
S 19’’ cabinets/racks

Due to the fact that the MP270 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.

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).

Error diagnostics

An error which occurrs during commissioning or operation is normally displayed on
the MP270 by means of a system message.

Appendix C of this manual contains a list of some of the most important system
messages and explanations on how to eliminate the causes.

3.1 Initial Startup

Action

During initial commissioning, the runtime software ProTool/ProRT and configuration
needed to operate the MP270 must be loaded from the configuration computer
onto the MP270. To do this, carry out the following steps in the sequence
described:

Step Action

1 Connect the IF2 interface (RS232/) on the MP270 to the PU or PC by means of a

suitable standard cable.

2 Switch on the MP270’s power supply.

Since, up to this point, no configuration has been loaded, the MP270 switches
automatically to download mode and waits for data transfer from the PC/PU.

3 Start the download operation on the PC or PU to the MP270. The settings

necessary on the configuration computer for the download operation are
provided in the user’s guide

ProT ool Configuring Windows-based Systems

.

The MP270 checks the connection to the PC/PU. If the connection is not
available or defective, the MP270 issues the corresponding error message.

If the connection is correct, downloading of the configuration begins. The runtime
software is automatically downloaded with the configuration data.

After downloading has been completed successfully , the MP270 restarts and
displays the start screen associated with the configuration just loaded.

Set date/time

When the MP270 is disconnected from the power supply for a longer period, e.g.
after the initial commissioning, the date and time have to be updated. Information
on this is available on Page 5-16.

4.4 Operating Screens

What is a screen?

Screens visualize the progress of processes and display specified process values.
A screen contains logically related process data which the MP270 can both display
and modify by operating the individual values.

Screen partitions

A screen is basically composed of static and dynamic sections. The terms “static”
and “dynamic” do not refer to the possibility of dynamically positioning screen
partitions but to the connection to the PLC.

Static partitions, e.g. text and graphics, are not updated by the PLC. Dynamic
partitions, e.g. input and output fields, trend curves and bars, are linked to the PLC
and display current values constantly read in from the PLC memory. Their
connection to the PLC is established by means of tags.

Figure 4-3 illustrates an example of the partitioning of a screen on the MP270.

processes. A message can contain text and tags. Parts of the text can be
configured to flash or be underlined to distinguish it from other parts of the text.

The MP270 displays the following types of message:

 Event messages

indicate normal operating and process statuses and process progress, e.g.
– Motor on
– PLC in manual mode
– Operating temperature xx reached

 Alarm messages

indicate critical or dangerous operating or process statuses and require a
response in the form of an acknowledgment.

Examples of alarm messages:
– Motor temperature too high
– Coolant empty
– Valve will not open

 System messages

indicate statuses and faults in the MP270 and PLC or communication between
them. They are triggered by the MP270 or PLC.

Examples of system messages are provided in Appendix C.

Message events

Messages are controlled by events and are triggered when a bit is set in the PLC.
The MP270 establishes the following message events and assigns them a time
stamp:

 Arrived

time at which a message was triggered by the PLC or MP270.

 Departed

time at which a message was withdrawn by the PLC.

 Acknowledged (alarm messages only)

5.3 Trend Graphics

Purpose

Trend graphics on the MP270 provide an especially clear visualization of
continuous process data values. In the case of processes which change very
slowly, it is possible to visualize trends of previous events, thus enabling estimation
of future trends within a process. On the other hand, the output of data concerning
processes which run extremely quickly enables large quantities of data to be
evaluated by simple means.

Configurable properties

The MP270 can depict several different trends in the trend graphic at the same
time. The following properties are among those which can be configured for a trend
graphic:

 Representation

Different trends can appear in different colors, as lines, dots or bars.

 Types of trend

–

Real-time trend

The MP270 reads just one trend value from the PLC per pulse or trigger and
inserts it in the trend displayed.

–

Pattern trend

By setting a trigger bit, the MP270 reads all the trend values from the PLC
simultaneously and displays them as a trend.

 Trigger

The type of trigger determines how the MP270 reads the trend data:
–

Pulse triggering

The MP270 reads the data from the PLC within a defined time matrix.

–

Bit triggering

The MP270 reads the data, triggered by an event. The event is triggered by
the PLC through setting a defined bit.

 Limit values

The MP270 implements color changes to visually indicate that configured limit
values have been reached or exceeded.

5.6 Password Protection

Purpose

During configuration using ProTool, operating elements, such as input fields,
buttons and function keys, can be protected against unauthorized use by applying
a password. Important parameters and settings can then only be modified by
authorized personnel.

Password hierarchy

Hierarchically defined password levels 0 to 9 are provided for password protection.
When a password is assigned to an individual user or to a whole user group, the
permission to execute functions at a specific level is assigned simultaneously. If an
user is assigned to password level 4, he only has the permission to execute
functions in password levels 0 to 4.

Password level

Password level 0:

The functions assigned to this level, the lowest in the hierarchy, have little or no
effect on operations. They normally concern functions without any input options,
such as displaying messages.

In order to trigger functions assigned to password level 0, no password needs to
be entered.

Password levels 1 to 8:
Functions are assigned to levels 1 to 8 according to their increasing importance.

Before triggering a function with a password level greater than 0 the MP270
requests the corresponding password to be entered.

Password level 9:
Only the superuser has the rights to execute functions assigned to password level

9 (system administrator or service technician). The superuser has access to all the
MP270 functions.

5.6.1 Logging in and out of the MP270

Login

After calling a password protected function, the MP270 automatically requests the
entry of a password. It is not necessary to enter the password again to trigger
functions in this or a lower level.

Logout

In order to rule out operation by unauthorized personnel, a password level greater
than 0 should not remain active on the MP270 over too long a period of time. The
following options are available to explicitly reset passwords levels:

 Configured logout time expires

If the MP270 is not used within the configured logout time (timeout), it
automatically resets the current password level to 0.

 Logout from MP270

If the configuration links the function

Logoff_user

with an operating element, the

element can be used to reset the current password level to 0 on the MP270.

Caution

With the SIMATIC S5, compression of the internal program memory on the PLC
(PU “Compress” function, integrated FB COMPR) is not permitted when an
operating unit is connected. Compression modifies the absolute addresses of the
blocks in the program memory. Since the operating unit only reads the address list
during startup, it does not detect any address modifications and subsequently
accesses the wrong memory areas.

If compression is inevitable during running operations, the operating unit must be
switched off before compressing.
