The PEG100-D are equipped with a fieldbus interface
DeviceNet. Thus, process automatization devices can
easily be interconnected.
1.1 DeviceNet - Interface
The fieldbus-system DeviceNet is described in the DeviceNet specification of the Open DeviceNet Vendor Association (ODVA). The technical and functional features of
the DeviceNet Standards are specified herein.
The PEG100-D have the functionality of DeviceNet
Group 2 Only Slaves.

2 Starting-up of the PEG100-D
The installed baudrate is saved in EEPROM. After power
ON/OFF the unit works with this installed baudrate.
How to install the auto baudrate detection:
If a fixed baudrate is installed and you want to change
this fixed baudrate to auto baudrate detection, you have
to proceed as follows:
- Switch off the power of the DeviceNet option.
- Set the address switches to the address 99 (initialisation of all values with default values).
- Switch on the power of the DeviceNet option.
The MNS - LED will glow orange.
- Switch off the power of the DeviceNet option.
- Set the address switches to the MAC ID you want the
device to work with.
- Switch on the power of the DeviceNet option.
The MNS - LED will flash green if a communication between the PTR and an other device takes place.
The installed auto baudrate detection is saved in
EEPROM. After power ON/OFF the unit works with this
installed auto baudrate detection.
After power ON the unit must find a device to communicate with (duplicate MAC ID check) (for example a
master or a monitor) otherwise the MNS LED will not
flash green and it will be impossible to allocate the PTR.
2.1.2 Address Setting
It is necessarry in a network to give each device a specific address. Therefore the address switches have to be
set to the requested MAC ID (addresses between 0 and
64 are possible).
2.2 MNS - LED
The MNS - LED corresponds to the ODV Astandard. The
following additional features were integrated:
LED Colour: Function
––––––––––––––––––––––––––––––––––––––––––––
ORANGE permanent The address switches are set to
one of the possible baudrate
settings (90, 91, 92) or to "Initialisation with default values"
(99).
RED permanent Not allowed MAC ID

tina12e1 (0106) PEG100-D.ga
For starting-up the fieldbus
- the whole system has to be installed electronically.
- the master has to be configurated
- the address of the slaves has to be set
2.1 Baudrate and Address
Switch
2.1.1 Baudrate
Alternatively you can choose between two kinds of
baudrate installations:
- Auto - Baud - Rate - Detection
If the unit is switched on during data transfer on the network (minimum: 2 nodes installed with data traffic between these nodes) the unit detects automatically the
installed baudrate on the bus.
- Pre-installed baudrate
You can install three baudrates (125 kBaud, 250 kBaud
and 500 kBaud) by using the address switches (see figure 1).
The function of the address switches (Figure 1) is as follows:
Address Function
––––––––––––––––––––––––––––––––––––––––––––
0 - 64 MAC ID
(Address selection by address switches)
90 Baudrate 125 kBaud
91 Baudrate 250 kBaud
92 Baudrate 500 kBaud
99 Initialisation with default values and auto-
baudrate detection
How to install a fixed baudrate:
- Switch off the power of the DeviceNet option.
- Set the address switches to the address 90, 91 or 92
(depending on the baudrate you want)
- Switch on the power of the DeviceNet option.
The MNS - LED will glow orange.
- Switch off the power of the DeviceNet option.
- Set the address switches to the MAC ID you want the
device to work with
- Switch on the power of the DeviceNet option.
The MNS -LED will flash green if a communication between the PTR and an other device takes place.
After power ON the unit must find a device to communicate with (duplicate MAC ID check) (for example a
master or a monitor) otherwise the MNS LED will not
flash green and it will be impossible to allocate the PEG.

4 Supported Modes
The PEG100-D acts as a "DeviceNet Group Two Only Slave". It supports the modes Polling, Bit-Strobe, Change of
State/ Cyclic and explicit messagges. Please set the „Interscan Delay“ of your master to app. 20ms if your system is
as fast that is polls the PEG100-D at regular intervals shorter than 20ms.
4.1 Bit Strobe

5 Format of real values
According to the IEEE-754 standard real values are stored in floating point format. The floating point values are transmitted according to the following format:
Byte 2 3 4 5
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
Content SEEE EEEE EMMM MMMM MMMM MMMM MMMM MMMM
S means: Sign Bit, which means 1 = negative, 0 = positive
E means: Two-complement exponents with offset 127
M means: 23 bit mantissa. The most significant bit is always 1 and is, therefore, not stored.
Example:
The value -12.5
Byte number of Byte 3: Byte 2: Byte 1: Byte 0:
the floating C1 hex 48 hex 00 hex 00 hex
point value
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––
Content SEEE EEEE EMMM MMMM MMMM MMMM MMMM MMMM
Content in this
example 1100 0001 0100 1000 0000 0000 0000 0000
binary binary binary binary
Sign bit:
The bit S in this example is 1. That means the sign bit of the whole value (or of the mantissa) is „minus“.
Exponent:
The EEEE EEEE have the value: 1000 0010 binary. This value converted in decimal it is: 130 decimal. This value has
the offset 127. So the exponent is: 130 - 127 = 3
Mantissa:
Because the mantissa is normalized the most significant bit has the value 1, the next bit has the value 0.5, the next bit
has the value 0.25.
Bit number Value of the bit, if the bit is set to 1
bit 24 (MSB) 1
bit 23 0.5
bit 22 0.25
bit 21 0.125
bit 20 0.0625
bit 19 0.03125
bit 18 0.015625
bit 17 0.0078125
and so on
The MMM MMMM MMMM MMMM MMMM MMMM (23bit) have the value 100 1000 0000 0000 0000 0000. The
most significant bit (MSB) is always 1 (and not stored). You have to implement this most significant bit.
So the value of the mantisse is: 1100 1000 0000 0000 0000 0000 (binary).
Bit number Value
Bit 24 is set to 1 → 1
Bit 23 is set to 1 → + 0.5
Bit 20 is set to 1 → + 0.0625
So the mantissa has the value 1.5625
Whole Value:
The whole value is: -1.5625·23= -12.5
