Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

When this parameter is enabled, and
● Modules removed and inserted during operation will not lead to a ET 200S station failure.
● The actual configuration differs from the expected configuration, the ET 200S remains
engaged in data transfer with the DP master.
When this parameter is disabled, and
● Modules removed and inserted during operation will lead to an ET 200S station failure.
● The actual configuration differs from the expected configuration, there is no data transfer
between the DP master and the ET 200S.

2.2.3 Interference frequency suppression
The frequency of your AC power system can interfere with the measured value especially
when measuring in low voltage ranges and using thermocouple elements. Here, enter the
mains frequency in your system (50 Hz or 60 Hz).
The interference frequency suppression parameter applies to all analog electronic modules.
With this parameter, you also specify the integration and conversion time of the various
modules. See the technical data for the analog electronic modules.
2.2.4 Reference junction slot
This parameter allows you to assign a slot (none or 2 to 12) with a channel for measuring the
reference temperature (calculation of the compensation value).
Reference
For information on connecting thermocouples, refer to the manuals for the analog electronic
modules
.
2.2.5 Reference junction input
This parameter can be used to set the channel (0/1) for measuring the reference
temperature (calculation of the compensation value) for the assigned slot.
Reference
For information on connecting thermocouples, refer to the manuals for the analog electronic
modules
.

3.3.1 Diagnostics readout
Introduction
The slave diagnostics comply with IEC 61784-1:2002 Ed1 CP 3/1. Depending on the DP
master, slave diagnostics can be read out with
STEP 7 for all DP slaves that comply with the
standard.
Length of the diagnostics frame
● For the ET 200S with the IM151-1 BASIC, the maximum frame length is 43 bytes.
● The minimum frame length is
– 6 bytes (identifier-related diagnostics, module status, and channel-specific diagnostics
disabled via parameter assignment).

Example of reading out S7 diagnostics using SFC 13 "DP NRM_DG"
Here, you will find an example of how to use SFC 13 to read out the slave diagnostics for a
DP slave in the STEP 7 user program.
For the purpose of this STEP 7 user program, the following is assumed:
● The diagnostic address of the ET 200S is 1022 (3FEH).
● The slave diagnostics are to be stored in DB 82: Starting from address 0.0, length = 43
bytes.
● The slave diagnostics can be up to 43 bytes long.

3.3.3 Station statuses 1 to 3
Definition
Station statuses 1 to 3 provide an overview of the status of a DP slave.
Structure of station status 1 (byte 0)
Table 3- 3 Structure of station status 1 (byte 0)
Bit Meaning Cause/remedy
0 1: The DP slave cannot be accessed by the DP
master.
•Is the correct PROFIBUS address set on the DP slave?
•Is the bus connector plugged in?
•Voltages on DP slave?
•RS 485 repeater set correctly?
•DP slave reset?
1 1: The DP slave is not yet ready to exchange data. •Wait, the DP slave is currently starting up.
2 1: The configuration data transferred from the DP
master to the DP slave do not match the slave
configuration.
•Correct station type or correct configuration of the DP
slave entered in the configuration software?
3 1: External diagnostic information exists. (Group
diagnostic display)
•Evaluate the channel-related diagnostic information, the
module status and/or the channel-related diagnostic
information. As soon as all errors have been eliminated,
bit 3 will be reset. The bit will be set again when there is a
new diagnostic message in the bytes of the
aforementioned diagnostics.
4 1: The required function is not supported by the DP
slave (for example, changing the PROFIBUS
address by means of software).
•Check the configuration.
5 1: The DP master cannot interpret the response of
the DP slave.
•Check the bus configuration.
6 1: The DP slave type does not match the software
configuration.
•Correct station type entered in the configuration software?
7 1: Parameters have been assigned to the DP slave
by a different DP master (not the one that currently
has access to the DP slave).
•The bit is always 1, for example, if you access the DP
slave with the programming device or another DP master.
•The PROFIBUS address of the DP master that assigned
parameters to the DP slave is located in the "master
PROFIBUS address" diagnostic byte.

Structure of station status 2 (byte 1)
Table 3- 4 Structure of station status 2 (byte 1)
Bit Meaning
0 1: Parameters have to be reassigned to the DP slave.
1 1: A diagnostic message exists. The DP slave will not operate until the problem is
eliminated (static diagnostic message).
2 1: The bit on the DP slave is always "1".
3 1: The watchdog is activated for this DP slave.
4 1: The DP slave has received the "FREEZE" control command 1.
5 1: The DP slave has received the "SYNC" control command 1.
6 0: Bit is always "0".
7 1: The DP slave is disabled, that is, it has been removed from the processing in progress.
1 The bit is updated only if another diagnostic message changes, too.
Structure of station status 3 (byte 2)
Table 3- 5 Structure of station status 3 (byte 2)
Bit Meaning
0 to 6 0: Bits are always "0".
7 1: •There are more diagnostic messages than the DP slave can store.
•The DP master cannot enter all the diagnostic messages sent by the DP slave in its
diagnostic buffer (channel-specific diagnostics).
3.3.4 Master PROFIBUS address
Definition
The diagnostic byte master PROFIBUS address contains the PROFIBUS address of the DP
master:
● that assigned parameters to the DP slave and
● that has read and write access to the DP slave.
The master PROFIBUS address is in byte 3 of the slave diagnostic information.

3.3.5 Identifier-related diagnostics
Definition
The identifier-related diagnostics indicate whether or not modules of the ET 200S have
errors/faults. In the case of the IM151-1 BASIC, identifier-related diagnostics start at byte 6
