1 Description
1.1 General
The Penning Gauge PEG100-P is supplied
ready for operation. Even so, we recommend to read these Operating Instructions
with care so as to ensure optimum operating
conditions right from the start.
These Operating Instructions contain important information on the functions, installation, start-up, operation and
troubleshooting of the
Penning Gauge PEG100-P
.
Important remarks concerning operational safety and
protection are emphazised as follows:
Warning Indicates procedures that must be strict-
ly observed to prevent hazards to persons.
Caution Indicates procedures that must strictly
be observed to prevent damage to, or
destruction of the PEG100-P.
Note
Indicates special technical requirements that the user
must comply with.
The references to diagrams, e.g. (1/3), consist of the Fig.
No. and the item No. in that order.
Unpack the PEG100-P immediately after delivery, even
if it is to be installed at a later date.
Examine the packaging for any external damage. Completely remove all packaging materials.
Note
Retain the shipping container and the packaging materials in the event of complaints about damage.
Check that the PEG100-P is complete
Carefully examine the PEG100-P visually.
If any damage is discovered, report it immediately to the
forwarding agent and insurer. If the damaged part has to
be replaced, please get in touch with the orders department.
1.2 Purpose
1.2.1 Penning Gauge PEG100-P
The PEG100-P is equipped with the fieldbus interface
Profibus-DP. Automated process instruments can be linked easily.
1.2.2 Profibus-DP
The norm EN 50170 decribes the fieldbus system Profibus-DP. Technical and functional features of the Profibus-DP are specified here. The Profibus-DP distinguishes between master and slave instruments. Master
instruments determine the data circulation. They transmit data to their related slaves and request data from
them. It is possible to configure the fieldbus as a monomaster or multi-master system.
The PEG100-P represents a slave unit which may receive different messages from the Profibus master and output corresponding replies in response to the information/commands from the master. In a Profibus system up
to 126 units including the master may be operated. Acorresponding slave address must be set up for the
PEG100-P.
1.2.3 Profibus-DP Master Configuration
Software
In order to configure the master together with the individual slaves software packages are available from the
manufacturers of the master units.

1.3 Technical Description
1.3.1 Configuration of Fieldbus nodes in
Profibus-DP
1.3.1.1 GSD File / Main Equipment File
Note
The GSD file is available in the internet.
The properties and capabilities of a Profibus-DP unit are
documented in the GSD-File. This is a file format which
is defined by the standard, so that manufacturer independent project tools may be implemented for ProfibusDP systems by various manufacturers. For operation of
the configuration software please refer to the corresponding operation instructions provided by the manufacturer
of the configuration software.
1.4 Technical Data
The technical data as specified in the Operating Instructions for the PEG100 - tina14e1 apply . The following data
apply in addition to the Profibus-DP interface:
Supported Baud Rates:
9.6 k Baud
19.2 k Baud
93.75 k Baud
187.5 k Baud
500 k Baud
1.5 M Baud
Expanded User Parameter Data
5 bytes of parameter data are required.
Configuring
The number of input and output data is 2 bytes each.
Sync-Mode and Freeze-Mode
The sync-mode and the freeze-mode are supported.
1.5 Supplied Equipment
The supplied equipment is the same as detailed for the
PEG100 in Operating Instructions tina14e1. The following items are supplied in addition:
- Profibus DP interface built into the PEG100,
PEG100-P Part Number 351-005
- Operating Instructions tina15e1

2 Operation
2.1 Operation of PEG100-P
The fieldbus’ operation requires
- the master’s configuration,
- setting of the slave’s address and
- electrical installation of entire system.
2.1.1 Setting Slave’s Address
The two rotary switches on the right side of the
PEG100-P are for the setting of the address. Possible
setting addresses are in the range of 0 to 99. With the
use of both switches the address has to be switched into
the decimal code. The instruments has to be switched off
during the setting of the address. A change will not be
registered after the instrument is switched on.
The required decimal address is set by the address switches. Switch x10 sets the High Value (see example) and
switch x1 sets the Low Value.
After applying the operation voltage to the PEG100-P,
the device expects -in line with the Profibus specifications- an address message, a parameter message and a
configuration message. If these data have been received
by the device and if the received data match the unit’s
settings (slave address, configuration data and parameter data/ nominal configuration = actual configuration)
the unit will then enter the data exchange mode and the
„RUN“ LED (1/2) will come on. If this LED does not come
on after having started the system, an error has occurred
during the configuration phase. Please check the slave
5
tina15e1-a (0206) PEG100-P.ga
address set up in the master, the configuration and parameter data by referring to the GSD file.
Caution After having removed the cause for the
error in the configuration for the master,
the bus logic of the PEG100-P can only
be set to its normal operating state by
switching the POWER ON once more.
Factory default settings: slave address
„34“.
2.2 Input and Output Data
The designations used in the following for the input and
output data must always be seen from the controlling
(master) side. Thus, for example, measurement data
sent by the slave are designated as input data (as seen
by the master).
After successful run-up, i. e. slave address configuration
and parameter data have been received by the
PEG100-P corresponding to the data stored in the
PEG100-P, the unit will enter the „date exchange“ mode.
Here 2 data bytes are transmitted as input and output
data corresponding to the configuration (as stored in the
GSD file).

How to calculate the measurement value
The measurement values are calculated according to the
following formulas in the corresponding measurement
units.
Calculation formula in unit „mbar“
pressure p / mbar= 10
(output value / 500 - 9.5)
A special pressure’s value is calculated with the following formula:
value = 500 · (log (p / mbar) + 9,5)
Calculation formula in unit „torr“
pressure p = 10
(output value / 500 - 9.6249)
A special pressure’s value is calculated with the following formula:
value = 500 · (log (p / Torr) + 9,6249)
Calculation formula in unit „Pascal“
pressure p = 10
(output value / 500 - 7.5)
A special pressure’s value is calculated with the following formula:
value = 500 · (log (p / Pa) +7,5)
