1. OVERVIEW
1.1 Description and Features
The PROFIBUS Module (CB15/CB155) is a device that allows control of an inverter over a PROFIBUS-DP (SINEC
L2-DP) serial bus.
Features
- Retains the ability to access the internal parameter set of the inverter (CB15 only).
- Allows high speed cyclical communication over a PROFIBUS link.
- Ability to control up to 125 inverters using the PROFIBUS-DP protocol.
- Provides open communication conforming to all relevant aspects of DIN19245 Part 3. It may be used with any
other PROFIBUS-DP/SINEC L2-DP peripheral on the serial bus.
- Easy to install.
- Easy to configure with proprietary Siemens COM ET 200 software (parameterisation disc included).
- Output frequency (and hence motor speed) can be controlled by one of five methods:
(1) Digital frequency setpoint.
(2) Analogue setpoint (voltage or current input).
(3) Motor potentiometer.
(4) Fixed frequency.
(5) Remote data transmission via the PROFIBUS link.
The RS485 serial link is not available while the CB15/CB155 is connected to the inverter.
IMPORTANT
1.2 Application on a PROFIBUS Link
PROFIBUS-DP is defined as a draft standard in DIN 19245 Part 3. Data communication with the CB15/CB155
conforms to the specifications in the VDI/VDE 3689 ‘PROFIBUS Profile for Variable Speed Drives’ guideline. This
defines the user data structure through which a master can access the drive slaves. The user data structure is
subdivided into two areas that can be transmitted in each message frame:
Process data, i.e. control words and setpoints, or status information and actual values and
A parameter area for reading/writing parameter values, e.g. for reading out faults or information on the
attributes of a parameter, such as minimum/maximum limits, etc.
The structure of the user data is designated as Parameter Process data Objects (PPO) in the PROFIBUS variable
speed drives profile (VDI/VDE guideline 3689). There are five PPO types: user data with no parameter area with
two words or six words of process data, or user data with a parameter area and two, six or ten words of process
data.
The CB15/CB155 only supports PPO types 1 and 3.

PROFIBUS MODULE (CB15/CB155) English
Operating Instructions
5
During installation of the network you can configure on the master which PPO type is used to address the inverter
from the PROFIBUS-DP master. The choice of PPO type depends on the task of the drive within the automation
network. The process data is always transmitted. It is processed with the highest priority in the shortest time slices.
The process data is used for open-loop control of the drive in the automation network, e.g. switching on/off,
specifying setpoints, etc.
The parameter area provides the user with free access on the network to all the parameters located on the inverter,
e.g. for reading out detailed diagnostics information, fault messages, etc. This enables further information to be
called up on a higher-level system, such as a PC, for visualisation of the drive, without affecting the performance
capabilities of process data communication.
Control and operation of the CB15/CB155 via PROFIBUS-DP
All information required for the open-loop control of a variable speed drive in the network environment of an
industrial process is transmitted in the process data area
(see Figure 1) . Control information (control words) and
setpoints are transmitted from the PROFIBUS-DP master to the inverter. Information on the status of the inverter
(status words) and actual values is transmitted in the opposite direction.

The communication component of the interface board stores the received process data in the order in which it was
transmitted in the message frame. Each word in the frame is assigned a fixed function.
The CB15/CB155 supports the PROFIBUS-DP control commands FREEZE and SYNC.
A diagnostics parameter can be used to read detailed diagnostics information straight from the diagnostics memory
of the CB15/CB155.

2. INSTALLATION
Incorrect operation of the serial bus system can lead to an inverter being switched on inadvertently.
Commissioning work must only be carried out by personnel who are qualified in installing such
systems. Additionally, the guidelines associated with the installation of the inverter itself must be
followed (see section 2 of the inverter’s handbook).
WARNING
2.1 Installing the Module
The inverter must be switched off before the CB15/155 is either connected or disconnected. The CB15/CB155 is
powered directly from the inverter and therefore needs no additional external supply
2.1.1 CB15 Installation
Fix the CB15 to the front of the inverter by mating the D-type connectors together and then securing in position by
pressing the module onto the inverter.
2.1.2 CB155 Installation
Before connecting the CB155 to the inverter, it is necessary to set the following parameters to the correct values,
using the OPM2.
Fix the CB155 to the side of the inverter housing using the screws provided. Connect the CB155 to SK200 on the
inverter, using the supplied cable.

2.2 Connecting the Bus Cable
2.2.1 Terminals
2.2.1.1 CB15 Terminals
The PROFIBUS connection must be made using the D-type socket on the front of the CB15. Connections to this
socket are as follows:
Pin 3PROFIBUS Pconnection
Pin 8PROFIBUS Nconnection
Additionally, the cable shield should be connected to the shell of the D-type connector, which is connected to
protective earth via the CB15 and inverter. The connector must be screwed securely to the CB15 to ensure both
mechanical strength and earth continuity.
Note
As the stations must be ‘daisy-chained’ together (except for the stations at either end of the bus), there
must be two cables into the D-type connector - one from the previous station and one to the next station.
This bus topology means that a station may be disconnected from the bus or powered down while still connected
without affecting bus operation.

2.2.1.2 CB155 Terminals
The PROFIBUS connection will normally be made using the optional T connector 6SE9996-0XA21 ). This is
connected to the free connector on the side of the CB155, and is in turn screwed to the front of the CB155, thus
providing the PROFIBUS IN and OUT connections. See Diagram above.

2.3 EMC Measures
The following measures are required for interference-free operation of the PROFIBUS-DP. Additional information
on EMC precautions can be found in the ‘ET 200 Distributed I/O System’ manual.
2.3.1 Shielding
The conductors of the bus cables must be twisted together, shielded and installed separately from the power
cables with a minimum clearance of 20 cm. The shield for the bus cable should be connected to protective earth at
both ends.
For the CB15, this is achieved using the P-clip provided with the module as shown in the enclosed instruction
sheet.
For the CB155, if the specified cables are used, no further action is necessary.
Bus and power cable crossings should be installed at an angle of 90o.
2.3.2 Equipotential Bonding
If the cable shields are earthed at different sections of the system then equipotential bonding cables can be used to
reduce current flow in the screen between the inverters and the PROFIBUS-DP master.
The following equipotential cables are recommended:
16 mm2Cu for equipotential bonding conductors up to 200 m in length
25 mm2Cu for equipotential bonding conductors over 200 m in length
Use a large contact surface connection between the equipotential bonding conductors and the protective ground
conductor.
2.3.3 Cable Installation
Observe the following rules when installing cables:
- Bus cables (signal cables) may not be installed directly adjacent to power cables.
- Signal cables (and equipotential bonding cables) should be connected across the shortest possible path.
- Power cables and signal cables must be installed in separate cable runs.
- Shields should have large contact surface connections.
2.4 PROFIBUS-DP Bus Termination
For interference-free operation of PROFIBUS-DP, the bus cable must be terminated at both ends with bus
terminating resistors. The bus cable from the first PROFIBUS-DP station to the last PROFIBUS-DP station should
be treated as a single bus cable, so that the PROFIBUS-DP should be terminated twice.
The bus terminators must be connected to the first station (e.g. the master) and the last station (slave).
For the CB15, this is achieved by moving the switch mounted on the D-type of the PROFIBUS-DP connector to the
ON position.
For the CB155 this is achieved by fitting the dedicated terminating connector to the free position on the T connector
at the end of the link.
Note
(1) Ensure that you only connect the bus terminator to the first network station and the last network
station.

4. FAULT CODES
Fault codes are displayed and acknowledged for the CB15/CB155 in the same way as on the inverter. Several new
error codes specific to PROFIBUS have been added and are described below. Further help may be found in
section 5 (PROFIBUS Commissioning) and section 6 (PROFIBUS Troubleshooting).
Fault Code Cause Corrective Action
F030 * PROFIBUS-DP master link
failure Check that the bus connections are not inverted or shorted. Check that the bus connections between master and slave are
continuous.
Check that the baud rate is between 9.6 kBd and 12 MBd.
Check that the slave address is correct and unique.
Check that the required inverter has been included in the
configuration information for the master. (If using IM308B/C,
check that the inverter has been included in the slave list.)
Check that the master is sending telegrams of the correct type
(PPO1 or PPO3).
Check that the master is running correctly (IM308B/C is in RUN
mode).
Check that the slave type is correct. (If using IM308B/C, use the
configuration file on the supplied floppy disc to set the correct
slave type for the CB15/CB155 when configuring with COM ET
200).
F031 Link to inverter failed Check the integrity of CB15/CB155 mounting to inverter.
F033 * PROFIBUS telegram error Reconfigure the master to send telegrams of the correct type
(i.e. PPO type 1 or PPO type 3
- see section 6 ).
F036 Program fault Switch off power and then switch on again.
*
These faults relate to communication problems and will only cause the inverter to trip if it is under remote control
(P928 = 1 or 3).

Parameter Index (IND) (2nd Word)
The index (also referred to as a subindex in the PROFIBUS profile) is an 8-bit value and is always transmitted on
PROFIBUS-DP in the most significant byte (bits 8 to 15) of the parameter index (IND); the least significant byte
(bits 0 to 7) of the parameter index (IND) has the value 0.
When a parameter has an index, the index is also transmitted. The number of the element is transmitted with a
description element. The meaning of the description elements is given in the PROFIBUS variable speed drives
profile (VDI/VDE 3689).
The index is not used for the inverter’s basic parameter set.

Parameter Value (PWE) (3rd and 4th Word)
The parameter value (PWE) is always transmitted as a double word (32 bits). Only one parameter value can be
transmitted in a frame.
A 32-bit parameter value is composed of PWE1 (most significant word, 3rd word) and PWE2 (least significant
word, 4th word).
A 16-bit parameter value is transmitted in PWE2 (least significant word, 4th word). In this case PWE1 (most
significant word, 3rd word) must be set to value 0 on the PROFIBUS-DP master.
Example: Fixed setpoint 1: P41 = 29 (HEX)

Rules for Task/Reply Processing
− One task or one reply can only ever refer to one parameter value.
− The master must repeat a task until it has received the appropriate reply.
− The master detects the reply to an issued task:
Evaluation of the reply identifier.
Evaluation of the PNU parameter number.
Through evaluation of the IND parameter index, where appropriate.
Through evaluation of the PWE parameter value, where appropriate.
− The task must be transmitted completely in one frame, split task frames are not permitted. The same applies to
the reply.
− In the case of reply frames (actual values) which contain parameter values, the slave does not always reply with
the current value when the reply frame is repeated.
− When no information is required by the PKW interface in cyclical mode (only PZD data is important), the ‘no
task’ task must be issued.
