Digipact Bus ModBUS Bus

Device

CommunicationBus

Communicationinterface

Software

DevicesCircuit breakers equipped with Micrologic control units may be connected to eithera Digipact or Modbus communication bus. The information made availabledepends on the type of Micrologic control unit (A, P or H) and on the type ofcommunication bus (Digipact or Modbus).Switch-disconnectors may be connected exclusively to the Digipact communicationbus.

Communication bus

DigipactThe Digipact bus is the internal bus of the low-voltage switchboard in which theDigipact communicating devices are installed (Masterpact with Digipact COM,PM150, SC150, UA150, etc.). This bus must be equipped with a DC150 dataconcentrator (see the Powerlogic System catalogue).AddressesAddressing is carried out by the DC150 data concentrator.Number of devicesThe maximum number of devices that may be connected to the Digipact bus iscalculated in terms of “communication points”. These points correspond to theamount of traffic the bus can handle. The total number of points for the variousdevices connected to a single bus must not exceed 100.If the required devices represent more than 100 points, add a second Digipactinternal bus.

Communicating device Number of pointsDC150 data concentrator 4Micrologic + Digipact COM 4PM150 4SC150 4UA150 4

Length of busThe maximum recommended length for the Digipact internal bus is 200 meters.Bus power sourcePower is supplied by the DC150 data concentrator (24 V)..



ModbusThe Modbus RS485 (JBus) system is an open bus on which communicatingModbus devices (Masterpact with Modbus COM, PM300, Sepam, Vigilohm, etc.)are installed. All types of PLCs and microcomputers may be connected to the bus.AddressesThe software layer of the Modbus protocol can manage up to 255 addresses (1 to 255).The “device” communication module comprises three addresses linked to:b circuit-breaker manager;b measurement manager;b protection manager.The “craddle” communication module comprises one address linked to:b the craddle manager.The division of the system into four managers secures data exchange with thesupervision system and the circuit-breaker actuators.The manager addresses are automatically derived from the circuit-breaker address@xx entered via the Micrologic control unit (the default address is 47).

logic addresses@xx Circuit-breaker manager (1 to 47)@xx + 50 Craddle manager (51 to 97)@xx + 200 Measurement managers (201 to 247)@xx + 100 Protection manager (101 to 147)

Number of devicesThe maximum number of devices that may be connected to the Modbus busdepends on the type of device (Masterpact with Modbus COM, PM300, Sepam,Vigilohm, etc.), the baud rate (19200 is recommended), the volume of dataexchanged and the desired response time. The RS485 physical layer offers up to32 connection points on the bus (1 master, 31 slaves).A fixed device requires only one connection point (communication module on thedevice).A drawout device uses two connection points (communication modules on thedevice and on the craddle).The number must never exceed 31 fixed devices or 15 drawout devices.Length of busThe maximum recommended length for the Modbus bus is 1200 meters.Bus power sourceA 24 V DC power supply is required (less than 20% ripple, insulation class II).

Communication interfaceThe Modbus bus may be connected to the central processing device in any ofthree manners:b direct link to a PLC. The communication interface is not required if the PLC isequipped with a Modbus port;b direct link to a computer. The Modbus (RS485) / Serial port (RS232)communication interface is required;b connection to a TCP/IP (Ethernet) network. The Modbus (RS485) / TCP/IP(Ethernet) communication interface is required.

SoftwareTo make use of the information provided by the communicating devices, softwarewith a Modbus driver must be used.

Micrologic utilitiesThis is a set of Modbus drivers that may be used with a PC to:b display the variables (I, U, P, E, etc.) with the DDS (Data Display Software)application;b read/write the settings with the RSS (Remote Setting Software) application;b remotely control (ON / OFF) the device with the CSS (Control CommandSoftware) application.These softwares are available upon request.

SMS (System Manager Software)SMS is a software to monitor LV and/or MV electrical energy.The SMS family includes a software range depending on the application andfunction, from single product monitoring to the management of a multiple building:cPower Meter and Circuit Monitor unitscLV devicescSepam units.

Note:An opening order always takes priority over a closingorder.If opening and closing orders occur simultaneously, themechanism discharges without any movement of themain contacts. The circuit breaker remains in the openposition (OFF).In the event of maintained opening and closing orders,the standard mechanism provides an anti-pumpingfunction by blocking the main contacts in open position.Anti-pumping function. After fault tripping or intentionalopening using the manual or electrical controls, theclosing order must first be discontinued, then reactivatedto close the circuit breaker.When the automatic reset after fault trip (RAR) option isinstalled, to avoid pumping following a fault trip, theautomatic control system must take into account theinformation supplied by the circuit breaker before issuinga new closing order or blocking the circuit breaker in theopen position (information on the type of fault, e.g.overload, short-time fault, earth fault, earth leakage,short-circuit, etc.).

Electric motor (MCH)The electric motor automatically charges and recharges the spring mechanismwhen the circuit breaker is closed. Instantaneous reclosing of the breaker is thuspossible following opening. The spring-mechanism charging handle is used only asa backup if auxiliary power is absent.The electric motor (MCH) is equipped as standard with a limit switch contact (CH)that signals the “charged” position of the mechanism (springs charged).characteristics

Electrical closing pushbutton (BPFE)Located on the front panel, this pushbutton carries out electrical closing of thecircuit breaker. It is generally associated with the transparent cover that protectsaccess to the closing pushbutton.Electrical closing via the BPFE pushbutton takes into account all the safetyfunctions that are part of the control/monitoring system of the installation.The BPFE connects to the closing release (XF) in place of the COM module.

Remote reset after fault tripElectrical reset after fault trip (Res)Following tripping, this function resets the “fault trip” indication contacts (SDE) andthe mechanical indicator and enables circuit breaker closing.Power supply: 110 / 130 V AC and 200 / 240 V AC

Automatic reset after fault trip (RAR)Following tripping, a reset of the mechanical indicator (reset button) is no longerrequired to enable circuit-breaker closing. The mechanical (reset button) andelectrical (SDE) indications remain in fault position until the reset button is pressed.

This function opens the circuit breaker via an electrical order. It is made up of:c a shunt release (second MX)c or an undervoltage release (MN)c or a delayed undervoltage release (MN + delay unit).The delay unit, installed outside the circuit breaker, may be disabled by anemergency OFF button to obtain instantaneous opening of the circuit breaker.

Instantaneous voltage releases (MN)The MN release instantaneously opens the circuit breaker when its supply voltagedrops to a value between 35% and 70% of its rated voltage. If there is no supply onthe release, it is impossible to close the circuit breaker, either manually orelectrically. Any attempt to close the circuit breaker has no effect on the maincontacts. Circuit-breaker closing is enabled again when the supply voltage of therelease returns to 85% of its rated value.characteristics
