Section 2

ARC600 overview

Overview

Wireless Controller ARC600 is a compact, solution based device for remote controlling and monitoring of secondary substations, such as network disconnectors, load break switches and ring main units (RMU) in distribution networks. It enables the

SCADA system to wirelessly monitor and control the field devices over the public communication infrastructure (cellular network). Wireless Controller ARC600 utilizes the built-in wireless communication features for reliable and secure end-toend communication providing remote monitoring and control of three switching devices and can be expanded as required by using external I/O expansion modules.

The use of Wireless Controller ARC600 in distribution networks improves the quality of power distribution and reduces the outage time in the affected areas. Areas directly adjacent to these affected areas show reduced outages and overall effects. This also reduces the capital expenditures in the distribution network by allowing integration of legacy devices and contributes to more direct cost savings by facilitating preventative maintenance. The operational expenditure can be reduced by lowering the System

Average Interruption Duration Index (SAIDI) and System Average Interruption

Frequency Index (SAIFI), resulting in lower penalties for undelivered energy.

Wireless Controller ARC600 is also ideally suited to be retrofitted to existing applications thus enabling the remote control of these devices and further extending the life cycle of the switching devices itself.

Typically, the IEC-104 protocol is utilized for communication to the SCADA system but for the existing installations with a IEC-101 line or modem, Wireless Controller

ARC600 supports also IEC-101 communication (including dial-up) to the SCADA system.

The device uses the serial ports for console or application communication, the

Ethernet port for network communication and cellular connectivity for wireless applications.

Serial ports

The device has two application serial ports. Serial port 1 is configurable to either console or data mode and supports RS-232 only. Serial port 2 is configurable to multiple serial modes (RS-232/422/485). Serial port connectors are 9-pin D-sub male connectors. Serial ports function as DTE devices.

Console/serial port 1

The console switch enables or disables console access. When the switch is in the right position, serial port 1 is in the serial port mode, and when it is in the left position, serial port 1 is in the console mode.

The console switch is located below the serial port 1 connector. Turn off power from the device before toggling the console switch, as the switch position is read during the boot sequence only. The baud rate is fixed to 115200 bps when the port is configured in the serial console mode.

Control functions

The device is capable of controlling and monitoring an object, for example, a disconnector, and handling the object status information. The device can control and monitor up to three objects. The device can monitor the earthing switch position indications, with one function per disconnector object. Local/Remote indications are also a standard; each disconnector has its own Local/Remote position monitoring. In the Local position, control operations (open or close) can be performed at the site only.

In the Remote position, control operations can be performed from the SCADA system in the network control center.

Condition monitoring functions

Communication diagnostics and watchdog

The device is provided with a self-supervision system, that is, a watchdog function.

The self-supervision system handles run-time fault situations and informs the user of faults through the user HMI (function LED) on the front panel.

In addition to hardware supervision, the self-supervision system is able to re-establish the cellular connection and VPN connection (if applicable). Furthermore, it is able to restart the device as a last resort.

Disconnector control condition monitoring functions

Disconnector travel time monitoring

The OPEN and CLOSE indications are monitored. When a change occurs due to an activated control operation, the opening or closing travel time is measured. If the measured travel time is greater than or equal to the set limit values, an alarm is given.

The settings define how the disconnector travel time duration (state change from open to close or vice versa) is reported.

Travel time is reported in seconds. The alarm signals remain active until the fault condition is acknowledged.

Disconnector actuator motor overload protection

With an optional Hall effect sensor, the device is able to measure the load current that flows through the actuator during the control operation of the disconnector. This current measurement is effectively used to detect an abnormality in the mechanical motion, when the lever that operates the disconnector moves from one end position to the other (for example, from Open to Close). A slip in the mechanical gear unit or a mechanically stiff operation, due to insufficient lubrication or deviation in operation tube positioning, can cause an overload situation which may be harmful to the actuator motor if no action is taken to prevent overloading.

Even if MCB’s are used as an overload protection, they are not optimal from the maintenance point of view, as they require a site visit because the resetting is typically

managed manually. The device's intelligent overload protection function, for example, the resetting and adjustment of the current pick-up level, is managed remotely from a utility dispatch center, using a system such as SCADA. The overload protection is coordinated with the possible MCB in the same circuit so that the current pick-up setting is lower than the MCB operational level to avoid unnecessary site visits.

Monitoring of the pressure of SF6 gas

The SF6 insulated primary equipment is arranged by wiring the pressure sensor contact to one input of the device, used for monitoring the SF6 gas pressure. When the gas pressure drops below the acceptable limit, the falling edge of the digital signal triggers and activates an alarm signal. This information can be obtained as an alarm event from the network control system.

Battery charging and monitoring functions

Power backup for the station can be arranged by connecting 24 V (2 × 12 V) sealed lead acid batteries to the device. The batteries supply power to both the device and the communication device during a mains failure. As the batteries are charged by the device, the communication between the unit and the network control center is always operating irrespective of distribution network faults or planned outages.

The battery condition is secured by a battery load and condition monitoring test, activated remotely via a command from the SCADA system. In the test, a discharge resistor is connected in parallel to the batteries. During the test, the battery capacity is measured and reported as an Ah value to indicate the remaining capacity, so that maintenance can be optimized. The battery test can be started directly from the control room or run automatically according to the agreed timetable. During the battery load test, which takes 2...5 h, the voltage of the battery charger is shut off and the control functionality is blocked.

If the battery voltage drops to less than the set value, for example, 22 V, during the battery load test, the device generates an alarm event. This indicates that the lifetime of the batteries is ending or that an internal fault has occurred in the battery or its circuitry. In both cases, the battery must be replaced.

During normal control operations, the device makes condition measurements, such as the battery voltage minimum value and the maximum current. The battery condition and lifetime can be estimated based on these recorded values.

Power backup

Power backup for the station can be arranged by connecting 24 V (2 × 12 V) sealed lead acid batteries to the device. The batteries supply the device and keep the

29

Section 4


4.4.2

1MRS758459 C communication alive during a mains failure. Thus the communication between the device and a network control centre operates in any situation.

Depending on the application and the required maximum operation time, batteries of different capacity are used; the typical capacity is 17 Ah. With the 17 Ah battery, the maximum operation time is 48 hours (including safety coefficient) at ambient temperature of +20°C.

A low temperature reduces battery capacity and lifetime.

Heater control

The heater control is based on the environmental temperature. Heating is needed if the device is installed in a separate enclosure outdoors where the ambient temperature may be below 0°C. Heating is specifically required in very damp conditions when dehumidifying is needed. The heating control consists of switching on and off an output pin connected to an external control relay of the heating element (resistor), which is located in the enclosure, preferably next to the batteries and the electronics components.

The device contains an internal thermostat for controlling the external heater. The heater element can be set to be constantly on, for example, if the element contains an internal thermostat, constantly off or to be controlled by the environmental temperature.

The heater output pins are X4 7 and 8. This is defined by giving the parameter heater_output value “9”.

The settings are defined in the section [HEATER].

Low auxiliary voltage indication

The power supply module gives an internal alarm signal when a drop in the power supply voltage is detected (AC Fail). The indication of a low auxiliary voltage can be reported to any available communication protocol supported by the device.

Over/undertemperature indication

The power supply module gives an internal alarm signal when over- or undertemperature is detected inside the enclosure. The alarm is activated when the temperature inside the enclosure surpasses a set limit or decreases below a set limit.

Hysteresis can be set for both indication functions. The indication can be reported through any available communication protocol supported by the device.

Temperature compensation of battery charging voltage

The charging voltage of the internal battery charger of the device is temperaturecompensated. The compensation factor is approximately -40 mV/°C. The data about the temperature is acquired with the help of a 2.2 kΩ NTC thermistor that is connected to pins 3 and 5 of the connector X2.1. If the battery charger is not used to charge the battery, the thermistor or the 2.2 kΩ resistor must still be installed between the pins 3 and 5 of the connector X2.1. Otherwise, the overvoltage protection of the charger may activate and prevent the device from starting.

It is recommended to install NTC thermistor between the batteries.

Battery deep discharge protection

When the battery voltage falls below a certain value, the battery is almost empty. To prevent battery damage, the battery should not be further discharged. The battery deep-discharge protection function disconnects the battery from the device in two cases.

• AC supply is not available to charge the battery.

• Battery voltage stays long enough below the defined limit.

Usually the deep-discharge protection causes the device to shut down due to lack of power. The device recovers once the AC supply becomes available again or it is powered up with DC on the modem-supply pin (X2.1 pin 6). External loads such as a

Hall sensor, additional DC-powered ARC600 devices or the supply for input circuits should not be connected directly to the battery but to the “master” ARC600 24 VDC

In/Out pin (X2.1 pin 6). This way, the whole load can be removed at once when the deep-discharge protection is required. The settings are defined in the section

[BATTERY_DISCHARGE_PROTECTION].

Battery capacity test

The device can test the capacity of the battery by disconnecting the charger and draining the battery to almost empty using an external loading resistor. The test is completed when the battery voltage reaches the defined voltage limit. The battery capacity can be returned by protocol communication in ampere-hours. The battery draining current is measured by external Hall sensor connected to analog input 1 (X4

3-4). The loading-resistor current should be routed through the relay contacts of X4 pins 5 and 6.

The test is started by protocol communication command. The information object is defined in the section [BATTERY_TEST_CONTROL_SC].

Certain conditions can be defined to abort the test.

• AC voltage is missing.

• Temperature is too high.

• Temperature is too low.

• Battery voltage does not reach the defined completion limit during timeout.

• Battery draining current too low.

• Battery draining current too high.

• Abortion command is issued by protocol communication.

The test is completed when the measured battery voltage stays below the defined voltage limit. This means the battery is almost empty and the available capacity can be estimated by multiplying the consumed charge by compensation factor. For example, if the defined target voltage means the battery to be 90% discharged, a multiplication factor 1.11 can be used to estimate the available total capacity. The device can compensate the cabling-loss voltage and include its internal charge consumption to the total capacity.

Usually, the disconnectors are internally blocked during the battery test and the test should be remotely stopped (information object

[BATTERY_TEST_CONTROL_SC]) before the disconnectors can be operated. The blocked state can be indicated by configuring the local/remote status to double-point indication [DISCONNECTOR_LOCREM_xx].

The load limiter functionality and the heater are disabled during the test.

Settings

The battery capacity test settings are defined in the section [BATTERY_TEST].

Remote control of the battery test function

Once the battery test functionality is enabled on the configuration file, it can be remotely controlled by protocol communication. The information object is defined in the section [BATTERY_TEST_CONTROL_SC].

The measured capacity is always reported after the test is completed. The information object is defined in the configuration file section

[BATTERY_TEST_CHARGE_FPI].

Measurement file

The device can generate the internal measurement file from the battery capacity testing. The measurement file is written every averaging_interval_sec and each line contains a time stamp, status, battery voltage, discharge current and the charge consumed so far. The file header contains the unloaded battery voltage before the load is applied. The last line of the file contains information whether the test was completed successfully or aborted for a specific reason.

Measurement functions

The device measures the battery voltage and the ambient temperature. The temperature measurement is calibrated to measure the ambient temperature of the device mounted in an enclosure. The temperature measurement is used to compensate for the charging voltage of the batteries and for activating or deactivating heating in cold environments. The battery voltage is measured as two values: the minimum battery voltage and the maximum current during control operation. The minimum battery voltage indicates the lowest voltage measured during a battery test or during an object's operation. The battery-charging voltage indicates the present voltage on the battery poles. The values can be read from the network control center via the supported communication protocols. The minimum battery voltage and the maximum current can be reset via the serial bus.

The device supports a general-purpose analog input that can be used as a transducer input. It supports voltage mode -5…5 V, ±300 mV (-10...+55°C, 0 V...+5 V).

The input can be used as current mode 4...20 mA using an external resistor.

Temperature measurement

The device has four temperature sensors.

Processor temperature

The ambient temperature of the process is measured by a sensor whose measurement result is available on the System tab of the Web user interface and with the command line command temperature. The measurement data of the sensor is not available with protocol communication.

Communication module temperature

The internal temperature of the wireless communication module is available on the

Web user interface under Tools/Modem Info and with the command line command modeminfo. The measurement data of the sensor is not available with protocol communication.

Sensor for the temperature compensation of the charging voltage

The internal sensor of the device adjusts the battery charging voltage based on the battery temperature. The data about the temperature is gained with the help of a 2.2 kΩ

NTC thermistor that is connected to pins 3 and 5 of the connector X2.1. The thermistor is located between the batteries. The measurement data of the sensor is not available with protocol communication but it is only used for adjusting the charging voltage.

Ambient temperature

The temperature of the device casing is used for estimating the ambient temperature.

Because the power consumption of the device affects the casing temperature, its effect is compensated based on calculations. The compensation parameters are defined in the setting file section [PHYSICAL_TEMP].

The ambient temperature calculated from the casing temperature is available with protocol communication. The temperature object is defined in the setting file section

[TEMPERATURE_FPI]. This temperature is also used for temperature alarm

([TEMPERATURE_LOW_SPI], [TEMPERATURE_HI_SPI]), battery testing temperature guard ([BATTERY_TEST]) and heater control ([HEATER]).

• Ambient temperature (47-10) °C - 2 A * 3.5 °C/A = 30 °C

Load limiter

The device can detect excessive loading of battery due to jammed disconnector switchgear and disconnect the load before the actual physical overcurrent fuse trips.

The overload decision is based on both the consumed charge and duration of the loading. The current is measured usually by an external Hall sensor connected to analog input 1 (X4 3-4). The device uses a normally closed relay (X4 1-2, Load Cut) to break down the loading circuit by opening the relay contacts for a moment. Usually this is used to cut the holding circuit of motor contactors, not directly the motor current.

Overload detection settings

The overload detection settings are defined on section [LOAD_LIMITER]. The detection is based on the load current measurement by the external Hall sensor connected to X4 pins 3 and 4.

User interface

ARC600 configurator is a tool which is used to manage the device properties via a user-friendly, Web-based interface.

To use the Web configurator, only a computer with an HTML browser and a connection to the device are needed. With the configurator, it is possible to receive status information and set parameters and variables that control which applications and processes are used with the device.

After a successful login, the main window is displayed. It consists of the main navigation menu on the top, the navigation bar on the left, and the content area that displays the currently active content and controls.

When the program starts for the first time, the System/Information window is displayed in the content area. The main navigation menu on the top of the window is used to navigate between the different subsets of the available settings. Selecting an item from the main menu displays the available items related to this subset in the navigation bar. The first of these is displayed in the content area by default.

The navigation bar on the left contains the parameter groups in the subset. Selecting an item from this menu displays the content related to the selected group in the content area.

Setting Ethernet port function to LAN

Changing Port function to “LAN” disables automatic IP address detection. If Port function is set to the default value “auto”, the Ethernet LAN port tries to automatically obtain the IP address using DHCP when the device boots. If the DHCP discovery fails, the device automatically uses IP address 10.10.10.10.

The use of the IEC-104 protocol

The IEC-104 and IEC-101 protocols share the same ASDU level messaging but differ on the link level. IEC-104 is intended for packet-switched TCP/ IP communication whereas IEC-101 is intended for serial communication. By using the device, the

IEC-101 slaves (for example RTUs) can be connected to a IEC-104 master (for example SCADA). The device requests an event from the IEC-101 slave locally and sends them to the IEC-104 master. This eliminates the need to continuously poll the data remotely and therefore reduces the communication costs on pay-per-use wireless network.

See the technical note about Wireless Controller RTU_interoperability for more information on IEC 60870-5-104 and IEC 60870-5-101 interoperability.

Network protocol defines the network transmission layer protocol

(either TCP or UDP) used on IEC-104 network communication.

The IEC-104 standard protocol uses TCP, but for reliable slow speed packet switched networks (for example Mobitex), the UDP protocol can be used to minimize the packets transmitted over network. Note: The IEC-104 standard specifies only TCP protocol.

Network idle timeout

New connection priority

Max clients

Network idle timeout defines the idle timeout of the network connection in seconds. If there is no network data received during the specified interval, the connection is closed by the device. This parameter is required in order to detect partially closed connections and release the resources for new connections especially if the New connection priority parameter is disabled.

Value “0” disables the network idle timeout detection. The network idle timeout must be longer than IEC-104 link test interval (t3).

It defines the action when a new connection request arrives while a connection is already active. If the set value is ”No”, the new connection is rejected. If the set value is ”Yes”, the present connection is terminated and the new connection is accepted. It is recommendable to set this value to “Yes” in normal configurations having only one IEC-104 master.

Max clients defines the maximun number of connections

(redundancy group).

IEC-104 settings

TX window size (k)

The IEC-104 settings define the properties of IEC-104 link layer and application layer parameters as described in the IEC

60870-5-104 standard. The IEC-104 communication is carried out between the device and the IEC-104 master over the TCP/IP network.

TX window size defines the maximum number of I format APDU packets the device may send before requiring the IEC-104 master to acknowledge them. If there are k unacknowledged frames sent the device stops polling IEC-101 slave for events until acknowledgement is received. The k must be always less than the maximum sequence number defined below. The IEC-104 standard suggests k to be 12.

RX window size (w)

RX window size defines the maximum number of I format APDU packets the device may receive before sending acknowledgement to the IEC-104 master. The w should not exceed two-thirds of TX window size k. The IEC-104 standard suggests w to be 8.

Link test interval (t3)

Description

It defines the timeout in seconds the device waits for acknowledgement from IEC-104 master after sending last I format

APDU or control frame (e.g. link test). If no acknowledgement is received during the defined time the device will close the network connection and the IEC-101 link. The t1 must be longer than the network round-trip-time. The IEC-104 standard suggests 15 seconds.

This defines the timeout in seconds from the last received I format

APDU before sending acknowledgement. The t2 must be smaller than t1. The IEC-104 standard suggests 10.

This defines the interval in seconds how often the IEC-104 link is tested if there is no other activity. The recommended value depends on the criticality of the link. The IEC-104 standard suggests 20 seconds but for pay-per-use GPRS connections the practical value may be substantially longer.

Max sequence number

This defines the time in seconds how long a connected IEC-104 link can be in suspended state (STOPD) before the device closes the connection. Using this parameter increases the probability of detecting partially closed network connections especially in UDP mode.

These are the maximum sequence number used in IEC-104 communication. The default value “0” equals to 32767 as suggested by the IEC-104 standard.

This parameter must be enabled if the ASDU header lengths differ between the IEC-104 and the IEC-101. The information on the field must fit in the shorter one of the two. It’s not possible to convert e.g.

value 12000 to a one byte field.

Use ASDU type replacer

The ASDU type replace function can be used to convert an ASDU type (Original type) to another (Applied type) type e.g. in cases when the IEC implementation differs between master and slaves.

Packet collector

The packet collector can be used to collect many IEC-101 messages and events to a single network packet instead of sending every message separately. This function is useful for slow packet switched communication network (for example Mobitex) for speeding up especially the general interrogation response.

Determines if the packet collector is in use.

Use packet collector

Max bytes Max bytes defines the maximum bytes trigger for packet collector.

Before a new packet is inserted into the packet collector buffer the amount of bytes is checked. If the insertion of the new packet would cause the number of bytes in the packet collector to exceed

MAX BYTES, the old content is sent to the network before inserting the new one. The value should be smaller than the MTU/MRU of network used.

12.1 Modbus Gateway properties

The Modbus Gateway is an adapter application enabling conversions between serial and network Modbus protocols. The gateway can operate in one mode: connecting the network master to serial slaves.

The gateway offers a number of core properties.

• Supports Modbus RTU and Modbus ASCII serial protocols

• Supports Modbus TCP, Modbus RTU over TCP, Modbus RTU over UDP,

Modbus ASCII over TCP and Modbus ASCII over UDP network protocols

• Generates and filters out gateway exceptions

• Makes automatic connection management

• Enables multiple server sessions over the network

• Offers unlimited amount of masters on the network side

Figure 19: Network master to serial slaves mode

In the “Network master to serial slaves” mode, the device acts like network server where masters (clients) can connect (the default port being 502) and transmit Modbus requests. The device makes conversions between network and serial protocols. If the slave does not reply during defined timeout or if the reply is corrupted, the device sends “gateway exception message” back to the master if the exception generation is enabled. Otherwise, the reply is returned. Multiple masters can connect simultaneously to the Gateway, which handles the multiplexing between masters.

Modbus gateway

Serial settings

If set to “Yes”, the Modbus gateway functionality is enabled for the serial port. Each serial port of the device has its own Modbus gateway definitions.

Serial port

Serial settings

Defines the serial port that the device uses for Modbus serial communication. The possible settings are “RS1”, which selects serial port 1 (RS-232 console/application port) and “RS2”, which selects serial port 2 (RS-232/422/485 application port). If a single serial port or RS-422/485 is required, port 2 is recommended. If

Port 1 is used, the console switch of the device must be in the

Application position. DIP switches below the DB-9 serial connector specify the RS-232/422/485 settings of Port 2.

Speed Defines the serial port speed for Modbus communication in bps.

The optimal speed depends on the connected Modbus equipment.

Modbus RTU communication uses 8 data bits and Modbus ASCII communication uses 7 data bits.

Defines the parity method used in Modbus serial communication.

If set to “None”, no parity method is used. If set to “Even”, an even parity bit is generated and inspected. If set to “Odd”, odd parity bits are generated and inspected.

Protocols

Description

If set to “Network master to serial slaves”, the slaves are on the serial side.

Serial protocol Defines the Modbus protocol that serial devices use in serial communication. The possible settings are Modbus RTU protocol and Modbus ASCII protocol. ModbusRTU is recommended because it is more efficient.

Network protocol

Defines the TCP/IP and Modbus protocol used on network communication. Possible protocols are Modbus TCP protocol over

TCP, Modbus RTU protocol over TCP, Modbus RTU protocol over

UDP, and Modbus ASCII protocol over UDP.

Framing

Slave response timeout

Inter-frame timeout

Defines the time in microseconds (millionths of a second) how long the device waits for the response from a Modbus slave. If the response is not received, the device can generate and return a

Modbus gateway exception. The reply timeout of the Modbus master must be greater than the gateway device timeout.

Otherwise, the flow of request-reply communication is violated.

The device does not accept a new request before the reply from the slave is received or the reply timeout is elapsed. The delays in network communication can vary especially in wireless networks.

When the slaves are located on the network side, ping or another method should be used to estimate the delay packets spend on network.

Defines the idle time in microseconds (millionths of a second) that marks the end of Modbus frame in serial communication. If the value is zero, the device uses the standard 4 character time. The recommendation is to use a value as small as possible to speed up communication and increase the value if problems arise. Some PC programs can insert unexpected delays between serial characters.

Exceptions

Generate gateway exceptions

Pass gateway exceptions

Network server settings

Defines if the device generates and returns a Modbus gateway exception message to the master if no valid reply is not received from the slave. If set to “Yes”, the generation of exceptions is enabled. This functionality is useful for debugging.

If set to “Yes”, gateway exception replies from the slave side are passed to the master. If set to “No”, the replies are filtered away.

Server

TCP/UDP port

Defines the TCP or UDP port that masters can form connections to. Default Modbus TCP/IP communication port is 502. If multiple

Modbus gateways are running on same device (for both serial ports) the TCP/UDP communication ports must not be same. For example, ports 502 and 504 can be used. The network and the device's firewalls must enable TCP or UDP communication for that port.

Description

Defines how many network masters can be connected to the device simultaneously. The recommended value is at least 2 when using TCP communication. Otherwise if the device does not recognize a partially closed connection, forming new connections is not accepted by the device the time set in parameter

“Connection idle timeout” is elapsed.

If there has not been communication on this route during given amount of seconds, the device automatically closes the TCP connection to slave and therefore frees the slave’s communication resources. This is especially useful when multiple masters access the same slave. The recommended setting is about two times the polling interval of the master.

Defines if connection testing is performed by sending TCP keepalive packets at certain intervals. enabled for TCP network communication. If set to “Yes”, testing the TCP connection with slave is enabled.
