Ethernet Overview

2 ETHERNET OVERVIEW

Following it is presented general information about the Ethernet technology.

2.1 ETHERNET TECHNOLOGY

Ethernet is a technology for interconnecting local area networks (LAN) based on frames forwarding. It deﬁnes wiring and electrical signals for the physical layer, the frame format and protocol for media access control layer (MAC) of the OSI model.

Ethernet, however, mainly deﬁnes the physical medium and the frame format. Based on Ethernet, multiple protocols and higher-level services were speciﬁed and developed in order to perform desired activities over a network, such as packet routing, connection establishment, sending and receiving ﬁles, etc. Several of these protocols have also been widely disseminated and employed, such as IP, TCP, UDP, FTP, HTTP.

Widely used to interconnect computers in the ofﬁce environment, the Ethernet technology also started being used in industrial environments for interconnection of ﬁeld devices. For industrial environment also emerged different communication protocols based on Ethernet, among which we can mention Modbus TCP, EtherNet/IP, PROFINET.

Network Installation

4 NETWORK INSTALLATION

This chapter presents recommendations related to equipment installation in an Ethernet network.

4.1 IP ADDRESS

Every equipment in an Ethernet network needs an IP address and subnet mask.

The IP addressing is unique in the network, and each equipment must have a different IP. The subnet mask is used to deﬁne which IP address range is valid in the network.

For the smart relay SRW01-ETH, the programming of the IP address is made using parameters and the addressing switches present in the product. The address conﬁguration options depend on the protocol according to the product model - Modbus TCP, EtherNet/IP or PROFINET IO. See the chapter about the desired protocol for the description of these options.

4.2 COMMUNICATION RATE

The Ethernet interfaces of the SRW01-ETH smart relay can communicate using the 10 or 100 Mbps rates in half or full duplex mode.

The baud rate is programmed at P0753.

NOTE!

It is important that, for each Ethernet connection made between two points, the baud rate and the duplex mode are set to the same option. If the option AUTO is used in one of the points, you must set the other point also to AUTO, or to half duplex mode.

For PROFINET IO interface, the baud rate is locked to 100 Mbps as required by the protocol.

4.3 CABLE

Recommended characteristics for the cable:

Standard Ethernet cable, 100Base-TX (FastEthernet), CAT 5e or higher. Shielded cable. Maximum length between devices: 100 m.

For installation, it is recommended the use of shielded Ethernet cables speciﬁc for use in industrial environment.

4.4 NETWORK TOPOLOGY

To connect SRW01-ETH smart relay in an Ethernet network, usually the star connection is made using an industrial switch.

SRW01-ETH | 10

Network Installation

Figure 4.1: Star topology

It is also possible to make the connection in daisy chain, allowing a topology equivalent to a bus.

Figure 4.2: Daisy chain topology

NOTE!

When the equipment is turned off, the built-in switch is also deactivated, preventing communication with the subsequent equipment.

4.5 RECOMMENDATIONS FOR GROUNDING CONNECTION AND CABLE ROUTING

The correct connection with the ground decreases problems caused by interference in an industrial environment. The following are some recommendations about grounding and cable routing:

Always use shielded twisted pair Ethernet cables and connectors with metallic housing. Connect the equipment grounding via grounding terminal. Avoid the cable connection on multiple grounding

points, especially where there are grounds with different potentials. Pass signal cables and communication cables in dedicated pathways. Prevent laying these cables next to power

cables.

P0800 ... P0819 – READ WORDS #1 ... #20

Range: 0 to 65535 Default: Properties: RW, Sys

Description:

These parameters allow programming the number of read words (inputs: slave → master), as well as the content of each word.

Each of words #1 to #20 can be programmed by the user. By using these parameters it is possible to program the number of another parameter whose content must be made available at the network master input area. If, for instance, one wants to read from the SRW01-ETH smart relay the motor current in Amps, one must program the value 3 in one of these parameters, because the parameter P0003 is the one that contains this information. It is worthwhile to remind that the value read from any parameter is represented with a 16 bit word. Even if the parameter has decimal resolution, the value is transmitted without the indication of the decimal places. E.g., if the parameter P0003 has the value 4.7A, the value supplied via the network will be 47.

It will be added to the input area the words programmed in these parameters if the contents programmed for these parameters is different from zero. The ﬁrst parameter set to zero disables the use of itself and the other parameters in the sequence. For example, if you set:

P0800 = 680 (P0680 = status) P0801 = 3 (P0003 = current) P0802 = 0 (disabled)

Only two read words (state and current) will be communicated with the master. The same number of words programmed into the equipment must be programmed in the master when conﬁguring the network.

Modbus TCP protocol allows to access each parameter directly, and do not distinguish cyclic and acyclic data.

NOTE!

For the changes in these parameters be effective, the equipment must be powered off and on again, or an update must be performed by P0899.

P0850 ... P0869 – WRITE WORDS #1 ... #20

Range: 0 to 65535 Default: Properties: RW, Sys

Description:

These parameters allow programming the number of write words (outputs: master → slave), as well as the content of each word.

The words #1 to #20 can be programmed by the user. By using these parameters it is possible to program the number of another parameter whose content must be made available at the network master output area. If, for instance, one wants to write to the SRW01-ETH smart relay the control word, one must program the value 682 in one of these parameters, because the parameter P0682 is the one to program this information. It is worthwhile to remind that the value written from any parameter is represented with a 16 bit word. Even if the parameter has decimal resolution, the

SRW01-ETH | 20

Programming

value is transmitted without the indication of the decimal places. E.g., if a parameter has the value 5.0s, the value supplied via the network will be 50.

It will be added to the output area the words programmed in these parameters if the contents programmed for these parameters is different from zero. The ﬁrst parameter set to zero disables the use of itself and the other parameters in the sequence. For example, if you set:

P0850 = 682 (P0682 = control) P0851 = 0 (disabled)

Only one write word (control) will be communicated with the master. The same number of words programmed into the equipment must be programmed in the master when conﬁguring the network.

Modbus TCP protocol allows to access each parameter directly, and do not distinguish cyclic and acyclic data.

NOTE!

For the changes in these parameters be effective, the equipment must be powered off and on again, or an update must be performed by P0899.

P0899– UPDATE ETHERNET CONFIGURATION

Range: 0 = Normal Operation

1 = Update conﬁguration

Default: 0

Properties: CFG, Sys

Description:

It allows you to force a reset of the Ethernet interface, to update the settings made in the device parameters. When setting this parameter to “1”, the Ethernet interface is restarted, resulting in loss of communication during this process. After the process is complete, the parameter switch automatically to “0”.

6.4 MEMORY MAP

The smart relay SRW01-ETH has different types of data accessible through the Modbus communication. These data are mapped at data addresses and access functions as described in the following items.

6.4.1 Parameters

The SRW01-ETH Modbus communication is based on the reading/writing of the equipment parameters. All the drive parameters list is made available as 16-bit holding registers type. The data addressing is done with the offset equal to zero, which means that the parameter number corresponds to the register number. The following table illustrates the parameters addressing, which can be accessed as holding register:

Table 6.4: Parameters Access - Holding Registers

Parameter Modbus data address (decimal)

P0000 0 P0001 1

. . .

P0100 100

. . .

It is necessary to know the device list of parameters to be able to operate the equipment. Thus, it is possible to identify what data are needed for the status monitoring and the control of the functions. The main parameters are:

Monitoring (reading):

P0680 (holding register 680): Status word

Command (writing):

P0682 (holding register 682): Control Word

SRW01-ETH | 23

Modbus TCP

Refer to the user’s guide for a complete parameter list of the equipment.

NOTE!

All the parameters are treated as holding registers. Depending on the master that is used, those registers are referenced starting from the base address 40000 or 4x. In this case, the address that must be programmed in the master for a parameter is the address showed in the table above added to the base address. Refer to the master documentation to ﬁnd out how to access holding registers.

It should be noted that read-only parameters can only be read from the equipment, while other parameters can be read and written through the network.

6.4.2 Memory Markers

Besides the parameters, other types of data as bit markers, word or ﬂoat, can also be accessed using the Modbus protocol. Those markers are used mainly by the ladder programming function, available for the SRW01-ETH. Refer to the WLP software documentation for the description of those markers, as well as for the addresses via Modbus.

6.5 COMMUNICATION ERRORS

Communication errors may occur in the transmission of telegrams, as well as in the contents of the transmitted telegrams. Transmission and connection errors are directly processed by the Ethernet interface and by the TCP/IP protocol.

In the event of a successful reception, during the treatment of the telegram, the server may detect problems and send an error message, indicating the kind of problem found:

Table 6.5: Error codes for Modbus

Error Code Description

1 Invalid function: the requested function is not implemented for the equip-

ment.

2 Invalid data address: the data address (register or bit) does not exist. 3 Invalid data value:

Value out of the allowed range. Writing on data that cannot be changed (read only register or bit).

NOTE!

It is important that it be possible to identify at the client what type of error occurred, in order to be able to diagnose problems during the communication.

PROFINET

8 PROFINET

Following it shows operating characteristics of the SRW01-ETH smart relay using the for PROFINET communication.

8.1 IP ADDRESS CONFIGURATION

In a PROFINET network, IP address programming is usually done through the network itself, instead of being locally programmed in the product. In this case, you must program in the P0760 to option 2 (DCP). With this option, no local product conﬁguration will be used - IP address, subnet mask, DHCP or gateway. Conﬁguration of these properties must be received over the network using DCP commands. It is also possible to set the addressing switches to ’FF’ position, so that the IP address conﬁguration is not made locally, only via network via DCP. To set the IP address locally on the product - as well as other relevant parameters - you must use the parameters P0760 to P0769.

8.2 STATION NAME CONFIGURATION

In a PROFINET network, each equipment has a different Station Name, which is used to identify the equipment in the network.

The two addressing switches, next to SRW01-ETH Ethernet connectors, allow you to program how to conﬁgure the Station Name, where the switch Ê represents the most signiﬁcant digit and the switch Ë represents the less signiﬁcant digit.

Figure 8.1:

Addressing Switches

Values for switches 1 and2Conﬁguration

00h Station Name: do not program the Station Name, and this conﬁguration

must be done via network using the DCP protocol. Once programmed, the Station Name value is saved to non-volatile memory, and remains programmed even when the product is turned off. IP address: IP address settings are made using the parameters P0760 to P0769.

01h ... FEh Station Name: the combination of switches 1 and 2 form the value to

conﬁgure the Station Name sufﬁx. In this case, when powering the product, it will assume the Station Name ”SRW01-ETH-XY”, with ’X’ and ’Y’ being the value of switches 1 and 2 respectively (numbers ’1’ through ’9’ and letters ’A’ to ’F’). IP address: IP address settings are made using the parameters P0760 to P0769.

FFh Station Name and IP Address are not programmed locally, and all conﬁ-

guration must be done via network using the DCP protocol. Once programmed, the values are saved in non-volatile memory, and remain programmed even when the product is turned off.

Faults and Alarms

10 FAULTS AND ALARMS

E0129 - ETHERNET OFFLINE

Description:

Indicates communication failure between the slave and the network controller.

Actuation:

It occurs when, once established communication between the slave and the network master, there is an interruption in this communication. The method for detecting the interruption of communication depends on the network:

EtherNet/IP: timeout in I/O connection, or master goes to IDLE state. PROFINET: timeout on the cyclic communication between master and slave, or master goes to STOP state.

In this case, the device will show in the HMI E0129 message. This indication will automatically disappear at the moment when the communication is reestablished.

Possible Causes/Correction:

Verify whether the network master is properly conﬁgured and operating normally. Search for short-circuit or bad contact in the communication cables. Verify the entire network installation – cable laying, grounding.

E0130 - ETHERNET INTERFACE ACCESS ERROR

Description:

Indicates internal error in data exchange between SRW01-ETH smart relay and Ethernet interface.

Actuation:

It occurs when the control board can not exchange data with the Ethernet interface or when the Ethernet interface identiﬁes some internal error.

In this case, the device will show in the HMI an alarm message E0130. Is is necessary to restart the Ethernet interface, power cycling the product or using P0899.

Possible Causes/Correction:

Restore the factory conﬁguration, and then perform the device parametrization again. Hardware errors caused by the improper handling or installation of the product can cause this error. If possible,

test it by replacing the product.

E0131 - TIMEOUT ON MODBUS COMMUNICATION

Description:

It indicates fault in the Modbus TCP communication. Indicates that the equipment stopped receiving valid telegrams for a period longer than the one programmed in P0756.

SRW01-ETH | 36

Faults and Alarms

Actuation:

The parameter P0756 allows programming a period of time during which the equipment must receive at least one valid telegram via the Ethernetinterface otherwise, it will be considered that there was any problem in the communication. The time counting initiates after the reception of the ﬁrst valid telegram.

After the communication timeout has been identiﬁed, the E0131 message will be showed on the HMI. When the communication is reestablished, the error indication will be removed from the HMI.

Possible Causes/Correction:

Check network installation, broken cable or fault/poor contact on the connections with the network, grounding. Make sure that theModbus TCP client sends telegrams to the equipment in intervals shorter than the programmed

in P0756. Disable this function at P0756.
