Trebing & Himstedt | SPI 3 | Sartocheck 4
Introduction
The SPI 3 (SERIAL-PROFIBUS-INTERFACE 3) allows a PROFIBUS-DP master to
communicate with a Sartocheck 4 filter test device. This allows the Sartocheck 4 to
function as a real PROFIBUS station, whereby the SPI 3 converts the data to be
exchanged between the PROFIBUS-DP master and the Sartocheck 4 into a format
which is compatible with the other device.
Data are exchanged between the DP master and the SPI 3 in the form of telegrams
through a data channel, the size of which can be configured.
The SPI 3 is easy to install and configure and a separate program for configuration or
parameter setting is not necessary. Configuration is done using the respective
PROFIBUS-DP master.
Features of the SPI 3:
· DP slave at up to 12 Mbit/s
· Does not require special configuration software
· Simple and fast integration in PROFIBUS-DP networks

Safety notes
Safety notes for the planning stage
Observe the general rules for PROFIBUS components when planning the SPI 3
installation.
Please observe the following to avoid risk to personnel and damage to equipment and
to ensure that the SPI 3 functions correctly:
Safety regulations – Observe the guidelines in the VDE 0100 regulations for
handling electrical components,
– Observe the applicable safety and accident prevention
regulations.
Assembly personnel The SPI 3 must only be installed or de-installed by qualified
technical personnel with appropriate electrotechnical
qualifications.
PROFIBUS standard Observe the guidelines in the PROFIBUS standard IEC
61158.
Bus cable Bus wiring should only take place using special screened,
twisted pair PROFIBUS cable. The high data transfer rates
can only be guaranteed with the correct cable type.
Cable lengths Refer to the PROFIBUS norm for information on maximum
cable lengths for PROFIBUS.
Terminating resistors Terminating resistors must be used if the SPI 3 is installed at
the beginning or end of the PROFIBUS cable segment. In
this case, you should use PROFIBUS connectors which
contain an integrated terminating resistor. We recommend
use of connectors from ERNI and Siemens. If the bus is
incorrectly terminated, this can lead to errors in data transfer
or to damage to other stations on the bus.
Bus connectors You should only use commercially available PROFIBUS
connectors for connecting the bus. We recommend using
connectors from ERNI and Siemens.
Cable screen Screened cables are less sensitive to interference due to
electromagnetic fields. With screened cables, the
interference currents are led to ground through the
screening rail, which is electrically connected to the case. To
ensure that the interference currents which flow through the
screening do not themselves interfere with other devices, it
is important to provide a low impedance connection to the
protective ground. Observe the following rules for the
screens of the PROFIBUS cable and the serial interface
cable:
– The braiding of the screening should have a degree of

Safety notes
7
Sartocheck 4 | SPI 3 | Trebing & Himstedt
coverage of more than 80 %.
– The screening should include a braided screen and
should not consist solelyof foil screening, since the latter
can be easily damaged by cable tension and pressure.
– To ensure good immunity to interference at high
frequencies as well, the screening of the cable should be
attached to the screening rail at both ends of the cable.
Safety notes for installation and operation of the SPI 3
Please observe the following before connecting up the SPI 3 to avoid risk to
personnel and damage to equipment and to ensure that the SPI 3 functions correctly:
– The SPI 3 is designed as an interface between fieldbus devices with serial
interfaces and the PROFIBUS. Do not use the SPI 3 for any other purpose.
– The SPI 3 may only be installed or de-installed by qualified technical personnel with
appropriate electrotechnical qualifications. When connecting up the SPI 3, you
must observe the guidelines in the VDE 0100 regulations for handling electrical
equipment.
– Always mount the SPI 3 on a suitable top-hat rail.
– The cables used to connect up the SPI 3 should not apply any mechanical forces
to the device.
Danger!
Never open the case of the SPI 3 and do not make any modifications to the
device.
Warning!
Small objects or liquids must not be allowed to enter the case of the SPI 3
(e.g. through the ventilation slots) since this could damage the device.
Never cover up the ventilation slots in the case.
Large temperature differences between the storage location and installation
site can cause condensation to form within the case of the SPI 3, which can
damage the device. If large temperature differences are present, you should
wait at least 3-4 hours after installing the SPI 3 and before switching on the
power.

Connecting up to Sartocheck 4
Note!
To enable communication with the SPI 3, the Sartocheck 4 filter test device
must be version 02.02 or higher.
To ensure that the SPI 3 functions without errors, you should use a screened
cable for connecting to the serial fieldbus device.
– Ensure that the Sub-D connector for the Sartocheck 4 uses the pin assignments
shown in »Technical specifications« on page 17 (connect the cable screen to the
case of the sub-D connector).
– Attach the sub-D connector for the Sartocheck 4 to the serial interface socket on
the SPI 3.
Connecting up to the PROFIBUS
Note!
You should only use commercially available PROFIBUS connectors for
connecting to the bus. We recommend the use ofconnectors from ERNI and
Siemens.
If the SPI 3 is installed at the beginning or end of the PROFIBUS cable
segment, you should use PROFIBUS connectors which contain an integrated
terminating resistor. We recommend using connectors from ERNI and
Siemens.
To ensure that the SPI 3 functions without errors, you must ground the
screen of the PROFIBUS cable.
– Ensure that the PROFIBUS connector uses the pin assignments shown in
»Technical specifications« on page 17.
– Attach the PROFIBUS connector to the PROFIBUS interface socket on the SPI 3
and secure the connector with the retaining screws.
Setting the PROFIBUS address
Note!
The SPI 3 only updates its PROFIBUS address during a restart. Set the
PROFIBUS address on the SPI 3 before switching on the power, or turn off
the power briefly after changing the PROFIBUS address.
You should only use addresses between 01 and 99.

– The PROFIBUS address is set with the two rotary switches.
Example: In order to set the PROFIBUS address 68, turn the rotary switch for the 10’s
to 6, and the rotary switch for the units to 8.
Bus terminating resistor
Terminations of a PROFIBUS network must each be terminated with a bus
terminating resistor. Use standardized plugs with integrated terminating resistors.
Figure: Bus termination configuration for PROFIBUS (see PROFIBUS Norm)
Note!
Please observe the following when using the depicted passive terminating
resistor: Is the feeding voltage (+5 V) supplied by the device (SPI 3), the
PROFIBUS is shorted via the resistors when the device is disconnected
from voltage. PROFIBUS communication can be interrupted or completely
break down until the device is re-energized.
Use active resistors to avoid this problem, as in this case the terminating
resistors are fed with +5 V and GND independently from the device.

Starting up the SPI 3
13
Sartocheck 4 | SPI 3 | Trebing & Himstedt
Starting up the SPI 3
To start up the SPI 3, you need to configure the device. Configuration is done via
PROFIBUS configurator (PLC programming tool).
– Start the PROFIBUS configurator of the DP master (PLC programming tool).
– Load the »THDP0091.GSD« GSD file for the SPI 3 into the configurator (GSD by
download: www.t-h.de).
– Configure the SPI 3 as described in the configurator online help or user manual.
Select the respective module »SartoCheck« or »SartoCheckExt« for the extended
version 2.0 for configuration. Do not parameterize this module with special user
parameters.
SPI 3 Configuration
During configuration with the PROFIBUS configurator, you are asked to select a
module from the menu. The »SartoCheck« or »SartoCheckExt« module can be used.
Note!
The described module SartoCheck is valid for the SPI 3 release 17 and hig-
her. The described module SartoCheckExt is valid for the SPI 3 release 19
and higher.
Module selection depends on the respective SPI 3 application. All further
modules (not described herein) cannot be used for SPI 3 application with
Sartocheck 4.

Checking the SPI 3 for correct operation
14
Trebing & Himstedt | SPI 3 | Sartocheck 4
Checking the SPI 3 for correct operation
Several checks should be run before using the SPI 3 for data transfer.
Checking SPI 3 power feed
– At this stage, do not attach either the PROFIBUS interface or the serial interface.
– Switch on the power feed for the SPI 3.
The RUN LED should light continuously. If this is not the case, there is a fault in the
24 V power feed. Refer to »Error diagnosis and remedies« on page 15 for details of
how to locate the fault.
Checking PROFIBUS communication
– Connect up the PROFIBUS interface cable.
– Switch on the power feed for the SPI 3 (RUN-LED lights up).
– Start the DP master which has previously been configured for the SPI 3.
The PB LED should light continuously. If this is not the case, there is an error in the
PROFIBUS communication. Refer to »Error diagnosis and remedies« on page 15 for
details of how to locate the fault.
Checking serial interface communication
– Connect up the PROFIBUS interface cable and the serial interface cable.
– Switch on the power feed for the SPI 3 (RUN-LED lights up).
– Start the DP master which has previously been configured for the SPI 3 (PB-LED
lights up).
The RUN LED should light continuously. If it does not light, or it only flashes, there is
an error in the communication with the serial device. Refer to »Error diagnosis and
remedies« on page 15 for details of how to locate the fault.
If no errors were detected, the SPI 3 is ready for use. During data transfer, the TX or
RX LEDs will flash (see »Indicating elements« on page 9).
Evaluating PROFIBUS diagnosis telegrams
In case of communication failures (PROFIBUS), the SPI3 sends a diagnosis telegram
on DP master request. The diagnosis telegram contains general PROFIBUS
diagnosis data (see PROFIBUS Norm).
You can evaluate the diagnosis telegram through the DP master and/or a PROFIBUS
diagnosis tool (e.g. the PROFIBUS Scope).

Error diagnosis and remedies
15
Sartocheck 4 | SPI 3 | Trebing & Himstedt
Error diagnosis and remedies
If errors are detected, the pattern of flashing of the PB and RUN LED’s on the SPI 3
can be used for error diagnosis. The LED’s can flash with the following patterns:
Note!
If the PB LED (PROFIBUS) is off, the RUN LED is on continuously and no
longer indicates a valid LED code. Accordingly, the RUN LED can only be
used for diagnosis when the PB LED is lit.
The PROFIBUS diagnosis and error statuses are reset when the error is no
longer present or when the slave gets new parameter and configuration
values.
LED off LED short LED medium LED long LED on
LED off LED is ¾ off ¼ on LED is ½ off ½ on LED is ¼ off ¾ on LED always on
PB LED code Status Significance Remedy
PB LED off Correct data transfer
rate could not be
determined
– No PROFIBUS master in
the network – Connect up the DP master – Check the wiring
PB LED short DP master available – A master is available but
communication is not
taking place with SPI 3

Error diagnosis and remedies
16 Trebing & Himstedt | SPI 3 | Sartocheck 4
Note!
If errors occur during communication, the DP master runs a PROFIBUS
diagnosis. Evaluation of this diagnosis depends on the used DP master.
When using a bus monitor (e.g. the PROFIBUS Scope), you can also
evaluate diagnosis telegrams.
