2.1 Setting PROFIBUS address at optris CT
After mounting the PROFIBUS-DP-V1 interfaces, the optris CT will be supplied with voltage and the MODE
button is pressed until the entry “SL001” appears. Afterwards the favored slave address will be chosen with
the „UP” and “DOWN” buttons – this will be taken over after six seconds. Then the optris CT has to be
removed from the voltage for three seconds. This procedure must always be carried out when a new slave
address is set.
2.2 Information regarding GSD file
File name: IT010A90.gsd
Producer: Sensor Manufacturer
Slave name: Infrared Thermometer
Identity number: 0x0A90
GSD revision: 1.00
Please make settings via the Profibus configuration program (e.g.: SIMATIC MANAGER or Hilscher SyCon).

2.3 Operation of optris CT with the PROFIBUS-DP-V1 interface
After the GSD file (IT010A90.gsd) has been read into the configuration tool and transferred to the master, the
optris CT with PROFIBUS-DP-V1 interface is ready for data exchange. This can also be seen on the green
LED on the Profibus-DP-V1 interface, if the cover was removed from the optris CT (open only for testing
purposes).
2.4 Data conversion
The cyclic received data of the “object temperature” and the “internal sensing head temperature” are shown
in a 2 byte hex format. In this context the 1. byte is the high byte and the 2. byte is the low byte.
They are converted as following:
Hex format converts into decimal format, minus 1000 and divided by ten
Example: 0x04EB →1259 –1000 / 10 = 25,9 °C

4 PROFIBUS DP
Within PROFIBUS DP systems, the master (PLC, PC, etc.) generally communicates with many slaves (IO,
drive, etc.) whereas only the master can access the bus (sent unasked telegrams) while a DP slave only
sends telegrams if it has been requested by a master.
4.1 DP startup
Before master and slave cyclically exchange data with each other, the parameter and configuration data are
transferred from the master to the slaves during the DP startup. After sending the parameter and
configuration data, the master interrogates the diagnostic data of the slave until the slave signals its
readiness for data exchange. Depending on the amount of calculations that the slave has to perform by
receiving parameter and configuration data until it is ready for data exchange, this may take several seconds.
The slave therefore has the following states:
4.1.1 Parameter data
The parameter data are sent from the master to the slaves with the SetPrmLock request telegram; the
SetPrmLock response telegram contains no data and therefore consists of only one byte, the short
acknowledgment. The parameter data consists of DP parameters (e.g. setting of the DP watchdog, checking
of the IdentNumber (unique for each DP device)), of DP-V1/DP-V2 parameters and of application-specific
parameters that occur only once during the startup must be transferred. If an error occurs in the parameter
data, this is indicated in the diagnostic data and the slave remains in the state WAIT-PRM.

-PROFIBUS DP 13-
4.1.2 Configuration data
The configuration data are sent from the master to the slaves with the ChkCfg request telegram; the ChkCfg
response telegram contains no data and therefore consists of only one byte, the short acknowledgment. The
configuration data describe the assignment of the DP modules to the cyclic IO data that is exchanged with
the Data_Exchange telegram during the cyclic data exchange between master and slave. The order of the
DP modules attached to a slave in the DP configuration tool determines the sequence of the associated IO
data in the Data_Exchange message frame.
4.1.3 Diagnosis data
The diagnostics data is requested by the master with a SlaveDiag request telegram without data, the slave
sends the diagnostics data with a SlaveDiag response telegram. The diagnostic data consists of the
standard DP diagnostics (for example, state of the slave, IdentNumber) and application-specific diagnostics
data.
4.2 Cyclic data transfer
Core piece of the DP record is the cyclic data transfer. During the DP cycles the master exercises an IO data
transfer with each slave. The master send each slave the outputs with a DataExchange request telegram
and the slave answers with the inputs in a DataExchange response telegram. All output and input data are
transmitted each with a telegram in which the DP configuration (sequence of the DP module) defines the
assignment of the output or input data to the real process data of the slave.

-14 -
4.2.1 Diagnosis during cyclic data transfer
During cyclic data exchange, a slave can report a diagnosis to the master. In this case, the slave sets a flag
in the DataExchange response telegram; whereupon the master recognizes that the slave has new
diagnostics data, which he then picks up with the SlaveDiag telegram. The diagnostic data is therefore not in
real time with the cyclic IO data in the controller, but at least one DP cycle later.
4.3 Synchronization of sync and freeze
With the sync and freeze commands in the GlobalControl request telegram (broadcast telegram), the master
can synchronize the output of the outputs (sync) or the input of the inputs (freeze) for several slaves. When
the sync command is used, the slaves are first switched to the sync mode (acknowledged in the diagnostics
data), then the IO data is exchanged sequentially with the slaves via the DataExchange telegram, a
transmission of the sync command in the GlobalControl telegram then results in the slaves outputting the last
received outputs.
In freeze mode, a freeze command is first sent in the GlobalControl telegram, whereupon all slaves take over
the signals at their inputs and are then sequentially requested by the master with the DataExchange
telegram.
4.4 State of things within the master
The master distinguishes the status CLEAR (all outputs on the Fail_Safe value) and OPERATE (all outputs
have the process value). Typically, the master is switched to the CLEAR mode when e.g. the PLC goes to
STOP.

4.6 DP master class 1 and class 2
The class 1 master refers to the controller that performs cyclic I/O data exchange with the slaves, while a
class 2 master is a B&B device that generally only reads the slaves IO data in a read-only manner.
PROFIBUS-DP-V1 essentially refers to the acyclic read and write telegrams used to acyclic access data
records in the slave. With DP-V1 as well, a distinction is made between class 1 and a class 2 master. The
acyclic class 1 (C1) or class 2 (C2) connection differ in that the acyclic C1 connection is established with the
DP startup of the cyclic DP operation. From the state WAIT-CFG of the slave, acyclic DP-V1-C1 read and
write telegrams can be sent from the master to the slave, while the C2 connection has a separate connection
independent of the cyclic DP connection, which is usually is performed by a second (C2) master, so that e.g.
a manufacturer-specific configuration and diagnostics tool can access the data of the slave. When using two
masters, however, it must always be remembered that they share the bus access (a token is exchanged), so
that the time relationships are less favorable than with a mono-master system.

4.7 PROFIBUS access
M12 device socket
The M12 device socket is coded inversely and has 5 pins. Pin 1 and pin 2 transmit the signals of the
Profibus. These must under no circumstances be exchanged, otherwise the communication is disturbed. Pin
2 transmits +5 VDC and Pin 4 transmits GND for the active terminator. These may under no circumstances
be used for other functions as this may destroy the device. Pin 5 has no function.
The thread carries the shield, which is capacitive connected to the base of the housing box.
