Communication
To communicate with the systems control and other process automation equipment, SICAM Q100 features an
Ethernet interface and an RS485 interface.
Ethernet supports the device parameterization, the transmission of measured data, metered values, load pro-
files and indications/events, and time synchronization with NTP. Depending on the device model and parame-
terization, the communication protocols HTTP, Modbus TCP or IEC 61850 are used.
The RS485 interface supports the transmission of the measured data, metered values, load profiles, indica-
tions, and time synchronization. The Modbus RTU Master or Modbus RTU Slave protocol is used for commu-
nication.

2.1 Communication Interfaces
The communication interfaces of SICAM Q100 make 4 communication types possible using the corresponding
communication protocols:
• Modbus TCP Server via Ethernet interface
• Modbus RTU Master and Modbus RTU Slave via RS485 interface
• Modbus TCP/RTU Gateway (Modbus Gateway)
• IEC 61850 via Ethernet interface
If parameterized accordingly, the device can communicate over the Ethernet interface and simultaneously over
the serial interface. It is possible, for example, to parameterize and retrieve data over the Ethernet interface,
while the serial interface handles the protocol traffic with a Modbus slave device.
2.1.1 Communication via Ethernet Interface
Via the Ethernet interface the following functions are supported:
• Parameterization, analysis and diagnosis with HTML pages
• DHCP (Dynamic Host Configuration Protocol) to assign the network configuration (IP address etc.) to
clients in an Ethernet network with DHCP server
• Time synchronization via NTP
• Data transfer to connected devices via Modbus TCP or IEC 61850-Server
• Data transfer to SICAM PQS for fault record and power quality analysis
2.1.1.1 TCP/IP Protocol Stack
SICAM Q100 supports the following TCP/IP services:
•TCP/IPIPv4
• DHCP client (Dynamic Host Configuration Protocol)
• NTP (Network Time Protocol)
• HTTPS
• SNMPv3 (Simple Network Management Protocol)
NOTE

2.1.1.2 IP Address
To enable the device to communicate within the Ethernet network, you have to establish a network configura-
tion consisting of IP address, subnet mask and standard gateway.
The device is delivered with a default IP address that can be restored at any time by pressing the F4 softkey.
Each device also has a unique MAC address.
The default IP address and the default subnet mask are imprinted on the side panel:
Figure 2-1 Display Side with Softkey F4
Default IP Address and Softkey F4
The F4 softkey (see Figure 2-1) located on the right display side can be used to activate the factory-set default
IP address. When pressed (>3 s), this softkey activates the factory-set default IP address. After pressing the
softkey F4, the device restarts and the IP address and subnet mask are temporarily activated in the default
IP network configuration. The customer-specific IP configuration is not overwritten.
The network configuration settings can be displayed and edited via HTML pages or via the device display (see
Device Manual SICAM Q100 7KG95xx, order number E50417-H1040-C522). After a renewed restart the pa-
rameterized network configuration is used again.

Check for Twice Assigned IP Address
Serious problems can occur if the same IP address is assigned more than once in a communication network.
For this reason, an ARP request is sent to the own IP address during start-up of the device. If no response is
received from the communication network within 2 s, it is assumed that the IP address is not used in the net-
work.
Otherwise, the LEDs signal the multiple assignment of the IP address as an error message:
Figure 2-2 Error Message: RUN - Flashing, ERROR - On, H1 and H2 - Any Status
The device is not integrated into the network in this case and a different IP address has to be parameterized.
Reception of the Network Configuration from the DHCP Server
The network configuration can also be obtained from an external server. Using the DHCP protocol, the device
is integrated into an already existing network.
If the IP address 0.0.0.0 is configured, the device sends a query to the external DHCP server requesting the
network configuration immediately after booting. Having received the network configuration, the device launch-
es the Ethernet services.
If no DHCP server is available, disconnect the device from the network and start it using the default IP address
and subsequently assign a permanent IP address.

NOTE
If the device is directly connected to a PC, the PC will need a longer period to be able to detect the connection
and therefore to receive the ARP telegram. In this case it may not be detected when PC and device have the
same IP address.

The Modbus TCP server of SICAM Q100 supports the following Modbus functions:
2.2.2 Exception Responses for Modbus TCP Server and Modbus RTU Slave
The Modbus server performs a series of consistency checks of the Modbus client requests, and if errors (for
example request to read a nonexistent register) are detected, it generates Modbus exception codes which are
signaled to the Modbus client in exception responses messages.
The messages contain the following codes:
Exception Code 01 ILLEGAL_FUNCTION
• The Modbus client uses a function that is not supported by the Modbus server of the SICAM Q100. The
supported Modbus functions are listed in chapter .
Exception Code 02 ILLEGAL_DATA_ADDRESS
• An attempt is made to read out or write to a nonexistent Modbus register (see chapter 2.2.7, Modbus
mapping for valid registers).
• An attempt is made to read out or write to too many registers. A Modbus message enables reading out
125 holding registers and writing to 123 holding registers maximum.
• The Modbus client tries to write to a register in the Modbus server for which only read access is allowed
according to the Modbus mapping (see chapter 2.2.7).
NOTE
The Modbus functions are the same for Modbus TCP (Ethernet) and Modbus RTU (serial).

Exception Code 03 ILLEGAL_DATA_VALUE
• The redundancy client addresses a register that does not allow access to partial data. The register has a
complex data structure and is distributed across several registers. The register can be read or written only
as a whole.
• The Modbus client tries to write to the Modbus server for which the access rights are set to "read only".
Exception Code 04 SERVER_FAILURE
• Error during the time format conversion in the Modbus server because a faulty date/time format was re-
ceived via Modbus, for example month format > 12.
2.2.3 Properties and Parameterization of the Modbus TCP Server
Properties of the Modbus TCP Server
• Connection-oriented Ethernet protocol based on TCP/IP
• Use of IP addresses for addressing individual components connected to the bus (bus nodes)
• The Modbus TCP protocol has the TCP port number 502 reserved on the server side. It is possible to use
a parameterized port number.
• All data types in the Modbus TCP messages which are larger than 1 byte are stored in the big-endian
format, that is the most significant byte (MSB) is stored at the lowest register address and is transmitted
first.
• Communication sequence:
The client sends a request to the server to start a data transmission from the server to the client.
If the requested data are not available, the server sends an error feedback to the client.
• The Modbus TCP data packet has a maximum size of 260 bytes:
253 bytes max. for data and
7 bytes for the Modbus TCP header
Parameterization
The following parameters can be set for the Modbus TCP bus protocol (see also Device Manual SICAM Q100,
chapter 8):
