2.3 NUMERICAL REPRESENTATION
Decimal numbers are represented by means of digits without suffix. Hexadecimal numbers are represented with
the letter 'h' after the number.
2.4 ABOUT THE SCW100
The SCW100 (Smart Connection WEG) is a motor starter manager with a line of accessories developed to ensure
the drive and complete management of electric motor starters. It has an isolated fieldbus communication network,
RS485 with Modbus-RTU protocol, which allows connection to a PLC (edge device) that can send commands
and read diagnostics, processing and providing information for a higher level network.
The Starter Manager (SCW100-SM) performs all the work so that the starters operate properly, being responsible
for the drive and diagnostics, such as operating time, number of operations, reversals, etc. Such information can
be exchanged with the master controller via communication network.
The Starter Modules (SCW100-CM) are directly fitted (no screws required) to the contactors of the CWB9…18/
CWB25…38 line and MPW40 motor-protective circuit breaker. They generate the signals necessary for the Starter
Manager analysis (SCW100-SM). For details on mounting, refer to the installation guide that accompanies the
product (SCW100-CM). This installation guide is also available for download on the website: www.weg.net.
There are specific models of Starter Modules (SCW100-CM) according to the starter type: forward drive with
protection (motor-protective circuit breaker and contactor), reverse drive with protection (motor-protective circuit
breaker and two contactors), forward drive without protection (contactor), reverse drive without protection (two
contactors). It also allows you to connect auxiliary input and output devices (I/O) (pushbuttons, indication, drive
switches etc).
The interconnection between the Starter Manager (SCW100-SM) and the Starter Modules (SCW100-CM) is
made by RJ45 cables (SCW100-RJ). A single cable allows total control of the starter, without requiring any other
element for the control circuit, which ensures fast and simple installation, in addition to guaranteeing the correct
assembly (error-proof).

3 INSTALLING AND CONNECTING
This chapter describes the procedures for the electric and mechanical installation of the SCW100. The directions
and suggestions must be observed in order to ensure the safety of people and equipment and the proper operation
of the SCW100.
3.1 MECHANICAL INSTALLATION
The Smart Connection SCW100 was designed for industrial or professional use only, to be installed in electrical
panels or the like.
3.1.1 Environment Conditions
Avoid:
Direct exposure to sunlight, rain, excessive moisture or sea air.
Inflammable or corrosive liquids or gases.
Excessive vibration.
Dust, metallic particles or oil mist.
Closeness to strong magnetic fields or high-current cables.
Environmental conditions for operation:
Temperature: 0 °C to 55 °C (32 ºF to 131 ºF).
Air relative humidity: 5 % to 90 % non-condensing.
Pollution degree: 2, with non-conductive pollution. Condensation must not cause conduction through the
accumulated residues.
Exclusive use for Zones A and B according to IEC 61131-2.
Maximum altitude: 2000 m (6.600 ft) above sea level - rated conditions. For applications at higher altitudes,
contact WEG.
3.1.2 Positioning and Fixing
The Starter Manager (SCW100-SM) can be installed in any position. The Starter Modules are fitted to the contactors
of the CWB9…18/CWB25..38 line and MPW40 motor-protective circuit breaker. For details on mounting, refer
to the installation guide that accompanies the product (SCW100-CM). This installation guide is also available for

3.2 ELECTRICAL INSTALLATION
DANGER!
The following information is a guide for proper installation. Comply with applicable regulations for
electrical installations.
The Starter Manager (SCW-100-SM), shown in Figure 3.2 on page 3-2, is supplied with two removable terminal
blocks: one for the power cable connections (connector 5) and another for the RS485 communication interface
(connector 6) - both with 4 pins each. It also has four RJ45 terminals (connectors 1 to 4) to connect the Starter
Modules (accessories of the SCW100 line) or input and output devices. The connection is made through a RJ45
cable (SCW100-RJ), available in lengths of 1 m (3.28 ft) and 2 m (6.56 ft).
ATTENTION!
The RJ45 connectors available on the front of the Starter Manager (SCW100-SM) are exclusive for
connection to the Starter Modules (SCW100-CM). These connectors must not be connected to
ethernet networks, at risk of damaging the product.
ATTENTION!
It is recommended to use RJ45 cables (SCW100-RJ) of the SCW100 line. If cables with dimensions
different from the ones provided are required, they must not exceed 2 m (6.56 ft) and withstand the
minimum current of 500 mA.

ATTENTION!
Use a SELV/PELV power supply. The input power supply voltage must be compatible with the
SCW100-SM rated voltage.
ATTENTION!
To ensure proper protection for your equipment, use a type-T fuse with current capacity compatible
with the load.
ATTENTION!
Pin 4 (PE) of the power connector must be connected to a protective earth.
ATTENTION!
It is recommended that the 24 Vdc power supply for the digital outputs (pin 2 of the power supply
connector) pass through the machine/ equipment safety circuit so as to guarantee that, in emergency
situations, loads driven by the Starter Manager (SCW100-SM) will be turned off via function redundancy.

3.4 CONNECTING THE STARTER MODULES OR I/O DEVICES
The Starter Modules or input and output devices (I/O) are connected through the RJ45 connectors. There are 4
groups (connectors 1 to 4 - Figure 3.2 on page 3-2), divided according to Table 3.2 on page 3-5.

3.5 CONNECTING THE RS485 INTERFACE
The RS485 interface connections of the Starter Manager (SCW100-SM) must be made through connector 6
Figure 3.1 on page 3-1, according to Table 3.3 on page 3-5 and detailed in Figure 3.3 on page 3-3.

Operating Modes

4 OPERATING MODES
The SCW100 has two operating modes: Starter and Transparent. It is programmed at the factory to the "Starter"
mode, which simplifies the control, monitoring and diagnostics on the components of a forward and reverse
starter. In this operating mode, the SCW100 performs the complete management of motor starters, reporting
errors, alarms, times, diagnostics, etc.
The "Transparent" mode is intended to connect discrete components to the digital inputs and outputs of the
SCW100. In this mode, errors, alarms, times and diagnostics in general, related to the starting of motors, are not
checked. The transparent mode has three (3) digital inputs and two (2) digital outputs available for general purpose
in each RJ45 connector, that is, they can activate indication lamps, contactors, etc. and read pushbuttons, auxiliary
contacts, etc. This mode can be thought of as a remote digital input/output (I/O) unit.
To configure the operating mode, check the modbus addresses 400 to 403.
ATTENTION!
In the "transparent" mode, the maximum current per digital output must not exceed 250 mA.

Description of the Modbus Parameters/Addresses
SCW100 | 5-1

5 MODBUS ADDRESS/PARAMETER DESCRIPTION
5.1 FIRMWARE VERSION
The value read corresponds to the firmware version of the SCW100.
Modbus address: 001.
001 – Firmware Version
Adjustable
Range:
0.0 to 655.35 Factory Setting: -
Properties: ro, 16 bit
Value read: "123", corresponds to version "1.23" of the equipment firmware.
5.2 READING OF THE ROTATING SWITCHES
Hexadecimal-type rotary switches S1, S2 and S3, located on the side of the product, are used for the settings of
the Modbus-RTU network.
The value read of each switch is between 0 and 15, which represents 00 h to 0 Fh in hexadecimal.
Modbus addresses and function of each switch:
010 – Rotary Switch S1 - LSB (Least Significant Byte) of the Address
011 – Rotary Switch S2 - MSB (Most Significant Byte) of the Address
Adjustable
Range:
0 to 15 Factory Setting: -
Properties: ro, 8 bit
Modbus addresses 010 and 011 indicate the selected serial address using configuration switches S1 and S2.
Each device on the network must have an address that is different from all others.
012 – Rotary Switch S3 - Baud Rate, Stop Bits and Parity
Adjustable
Range:
0 to 15 Factory Setting: -
Properties: ro, 8 bit
The modbus address 012 indicates the baud rate of the serial interface in bits per second, parity and stop bits
for the bytes of the serial interface, selected using the configuration switch S3. This setting must be the same for
all the devices connected to the network.
NOTE!
If the configuration of switch S1, S2 or S3 is changed, it will only be valid after the SCW100 is turned
off and back on.
NOTE!
