Digital Energy Multilin 345 Transformer Protection System Communications Guide Communications Guide Communications interfaces The 345 has three communications interfaces. These can be used simultaneously: • RS485 • • Ethernet 345 TRANSFORMER PROTECTION SYSTEM – COMMUNICATIONS GUIDE 1–1...
CHAPTER 1: COMMUNICATIONS GUIDE RS485 interface The hardware or electrical interface in the 345 is two-wire RS485. In a two-wire link, data is transmitted and received over the same two wires. Although RS485 two wire communication is bi-directional, the data is never transmitted and received at the same time.
If a 345 Modbus slave device receives a transmission in which an error is indicated by the CRC-16 calculation, the slave device will not respond to the transmission. A CRC-16 error...

<242..253>:= private range <254..255>:= compatible range The 345 relay is identified in this protocol as “overcurrent protection”, so it will use the Function Type <160> for all the digital and analogues points proposed by the standard and mapped in this profile. For the other data supported by the device, the customer will have the capability to use them by setting a number from the private range.
Identification Type 9 (ASDU 9) is selected, up to nine measurands can be sent in the IEC103 slave answer. For each measurand, all metering values that the 345 supports, are available in order to be mapped. There are 3 possible configurable ASDUS.
The user is able to select the Information Number <1..255> and the Function Type <0..255> command mappings, but the Identification Type 20 (General Commands) is fixed.++ There are 32 configurable commands. In this case it will be necessary to define a new format. For example, FC500: 1–24 345 TRANSFORMER PROTECTION SYSTEM – COMMUNICATIONS GUIDE...

ETHERNET INTERFACE CHAPTER 1: COMMUNICATIONS GUIDE Ethernet interface The Ethernet option for the 345 provides both a 1300 nm optical interface, and a 10/100 auto-negotiating copper interface. To select which interface is active, a MODBUS setpoint (see below) must be modified:...

NOTE: active at a time. The 345 can be used as an IEC 60870-5-104 slave device connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the 345 maintains two sets of IEC 60870-5-104 data change buffers, no more than two masters should actively communicate with the 345 at one time.

M_ME_NB_1 analog data. Each setting represents the threshold value for each M_ME_NB_1 analog point. For example, to trigger spontaneous responses from the 345 when a current value changes by 15 A, the "Analog Point xx Deadband" setting should be set to 15. Note that these settings are the default values of the deadbands.
(one level of nesting) and all the standard data types. GOOSE settings changes will take effect only after the 345 relay is re-booted. One setting is available to Enable/Disable both Transmission and Reception. It is possible to change this setting from the Front Panel of the relay.
CHAPTER 1: COMMUNICATIONS GUIDE GOOSE transmission The 345 firmware supports one transmission dataset. All elements in the transmit dataset must be Booleans values. The user can define the number of items in the transmit data setup, to a maximum of 32.
Remote Devices. Instead, it is simpler to deal with Remote GOOSE messages. The 345 firmware is able to receive up to a total of 8 remote GOOSE messages transmitted from up to a maximum of 8 remote devices.
If a GOOSE message is received, and its header has not been configured for reception, the firmware ignores the message. It is possible to see this GOOSE status information from the 345 relay front panel. 1–66 345 TRANSFORMER PROTECTION SYSTEM – COMMUNICATIONS GUIDE...
Figure 3: EnerVista SR3 GOOSE Status page GOOSE Rx headers The 345 firmware supports GOOSE messages that contain up to one level of nesting, and that are capable of mapping only digital values to the remote inputs.

In the 345 there are many different settings where it is possible to select between a Contact Input (1 to 8 ), a Virtual Input (1 to 32 ) or a Logic Element (1 to 8 ). In all of these settings it is also possible to select Remote Input (1-32 ) if the GOOSE feature is enabled on the relay.
CHAPTER 1: COMMUNICATIONS GUIDE USB interface The USB inferface supports only the Modbus protocol. For information on using the USB port on the 345 relay, please refer to Chapter 3 of the 345 Instruction Manual.

For the 345 implementation of Modbus, this function code can be used to read any setpoints (“holding registers”). Holding registers are 16 bit (two byte) values transmitted high order byte first. Thus all 345 Setpoints are sent as two bytes. The maximum number of registers that can be read in one transmission is 125.
MODBUS FUNCTIONS CHAPTER 1: COMMUNICATIONS GUIDE For the 345 implementation of Modbus, this function code can be used to read any actual values (“input registers”). Input registers are 16 bit (two byte) values transmitted high order byte first. Thus all 345 Actual Values are sent as two bytes. The maximum number of registers that can be read in one transmission is 125.
Modbus Implementation: Preset Single Register 345 Implementation: Store Single Setpoint This command allows the master to store a single setpoint into the memory of a 345 The slave response to this function code is to echo the entire master transmission.
Function Code 08H Modbus Implementation: Loopback Test 345 Implementation: Loopback Test This function is used to test the integrity of the communication link. The 345 will echo the request. For example, consider a loopback test from slave 17: Table 39: MASTER/SLAVE PACKET FORMAT FOR FUNCTION CODE 08H...
Error Responses When a 345 detects an error other than a CRC error, a response will be sent to the master. The MSBit of the FUNCTION CODE byte will be set to 1 (i.e. the function code sent from the slave will be equal to the function code sent from the master plus 128).
345. 02 - ILLEGAL DATA ADDRESS The address referenced in the data field transmitted by the master is not an allowable address for the 345. 03 - ILLEGAL DATA VALUE The value referenced in the data field transmitted by the master is not within range for the selected data address.

USING THE MODBUS USER MAP Using the MODBUS User Map 345 relay units incorporate a powerful feature called Modbus User Map, that allows the user to read 125 non-consecutive data records. A master computer will often have to interrogate continuously several connected slave relays.
