PME−MP60DP
1 Introduction
This Operating Manual describes only those functions which differ from the
MP60. The features of the MP60DP correspond to those of the MP60.
The MP60DP carrier−frequency measurement module has been expanded to
include a Profibus interface. The features on the CAN−interface remain the
same; the object directory is expanded to include some parameters for the
Profibus connection.
The Profibus connection is made using a 9−pin sub−D connector (conforming
to standard) on the front panel next to the transducer port.
DP protocol is used on the Profibus.
The following are communicated:
− the measured values (gross, net, peak values)
− the status of the limit switches
− control bits for taring, zeroing, peak value store control and changing the
parameter set, and
− optionally, the limit values

2 How to connect to a PLC
The steps in successfully connecting to the Profibus:
1. Physically connect the device to the Profibus (see page 8 and page 9)
2. Configure the device parameters, see page 12 (can also be carried out
using HBM‘s “PME-Assitent“ software).
3. Configure the Profibus message and set up its parameters with the aid of a
configuration tool (such as Step7) and GSE files, or manually as shown in
chapter 6.2.
A GSE file describes the properties of a Profibus node in standardized form.
The configuration tool uses it to define which data held on individual bus
nodes will be exchanged on the Profibus.
5
A default GSE file for PME modules is supplied with the device (on system
CD: hbmxxx.gsd = German version; hbmxxxgse = English version).

2.1 Configuring and assigning parameters
• Start your configuration program (e.g. Step7; if you have no configuration
program, proceed to chapter 6.2)
• Load the HBM GSD file (PME system CD incl. GSD/GSE files for PME)
• Add an HBM device (Hardware catalog)
• From the hardware catalog choose the configuration you want on the
Profibus.

• Double-click on the configured entries to open the properties window and
select the required parameters.

Notes for users of the Simatic S7 PLC:
• To download consistent data of 3 bytes or over 4 bytes, use special
function modules SFC14 to read and SFC15 to write.
• In the case of the S7 3xx a maximum of 32 bytes of consistent data can be
downloaded.
To find out the meaning of the status bits and control word bits please refer to
the tables in chapter 6.3.

3 Installation
• Connect the MP60DP module to a 24 V supply voltage.
• Connect the Profibus cable to the MP60DP module. Ensure that a
terminating resistance is connected to the first and last Profibus unit (the
housing of the Profibus connector usually contains a sliding switch for this
purpose).

Please note the safety instructions before commissioning the device.
4.1 Pin assignment
For the pin assignment of the MP60DP module please refer to the Operating
Manual “PME industrial measurement electronics with MP60/MP07 module
field bus link”. On the front panel of the MP60DP is an additional 9−pin D-sub
connection socket for the Profibus connection.

5 Operation via the keyboard
−
During measurement you can press
the display (e.g. mV; V; Out,In; error messages).
Next to the status message “ERROR” the display shows the status of the
Profibus DP connection. One of the following status messages is displayed in
each case:
BD_SEAR (baud rate search)
WT_PARM (waiting for parameter)
WT_CONF (waiting for configuration)
DATA_EX (cyclical data communication)
ERROR (bus error)
+
− to view the status messages in
The LED shows the operating status (ready to take measurements, overflow
etc.) of the MP60DP. Instead of the CAN status (as with the MP60), however,
the Profibus status is displayed.
Operating status:

6 Setup for Profibus
6.1 Parameter assignment
The amplifier parameters are set via the keyboard or CAN−interface, as on
the MP60. The Profibus DP parameter assignment telegram defines some
parameters for the DP communication. If you use Profibus parameter
assignment tools which are able to evaluate the GSD files of GSD revision 1,
the following parameters are available for selection:

Tab 6.1: Meaning of the parameters
The data format set applies to all the measured values exchanged in the
cyclical data communication. The definition of the decimal places for the
formats integer 16 bits and integer 32 bits is adopted from the module setting
(display, CAN−bus) (e.g. when 3 decimal places is specified, 2.0 mm is
communicated as integer value 2000). The choice of data format also affects
the length of the input data (integer 16 bits = 1 word per analogue value,
integer 32 bits and floating = 2 words per analogue value).

The targeted operation of the required control bits in the control word allows
you to secure all the functions not required against accidental operation in the
event of an error; otherwise, for example, the zero point set could be lost.
If you are using older parameter assignment tools the parameter values will
have to be converted to decimal or hexadecimal values:

The formats of the cyclically communicated data content are specified in detail
in chapter 6.3. The measured values are offered optionally as a 16-bit integer,
32-bit integer or 32 bit float. The values are always scaled to physical size
with the number of decimal places of your choice. Information on whether the
16 bit format or a 32 bit format is used and on the number of decimal places is
defined in the parameter assignment message.
Typical combinations are predefined in the GSD file. If you require other
combinations you can expand the GSD file accordingly using the following
specifications.

6.2.1 Defining your own configuration combinations
Only one configuration entry is available. The special identification format
(special format) must be used for this. The manufacturer−specific data
specifies the contents and thus also the length of the input data and is 2 bytes
in length.
CFG entry no. Meaning Contents
0 channel 1 special format with inputs and outputs, maximum 9 words
output, maximum 13 words input, 2 bytes comment length
(data)
The following input and output data can be configured for the cyclical data
communication. The choice of which data is actually transferred is
communicated via the manufacturer−specific data of the special identification
format.

The length of the input data is the sum of all the data lengths selected for the
communication in words. When selecting the 32 bit format and the float format
for measured values, the length values in brackets must be used.

6.3 Cyclical data exchange
Depending on the configuration, the following data content is exchanged:
6.3.1 Inputs (from MP55IBS to the PLC) Measured values
Measured values can be communicated in various forms of representation.
The forms of representation available for selection are floating (2 words, 32
bit), 16 bit fixed point number (1 word, 16 bit integer in two’s complement,
decimal place must be known to the reader) or 32 bit fixed point number (2
words, 32 bit integer in two’s complement, decimal place must be known to
the reader). For conversion of the values to fixed point representation the
number of decimal places in the module parameter assignment (display,
CAN−bus) is used as a basis.
