TM3 Bus Couplers General Description

Introduction

The Modicon TM3 bus couplers are devices designed to manage EtherNet/IP, Modbus TCP, Modbus serial line or CANopen communications, depending on the reference, in association with TM2/TM3 I/O expansion modules in a distributed architecture.

Software configuration is accomplished with:

 The EcoStruxure Machine Expert software (refer to the Modicon TM3 Bus Coupler -

Programming Guide).

 The EcoStruxure Machine Expert - Basic software (refer to the Modicon TM3 Bus Coupler

(EcoStruxure Machine Expert - Basic) - Programming Guide).

General Overview

TM3 Bus Coupler Distributed Configuration Architecture

Optimized distributed configuration and flexibility are provided by the association of:

 Controller  TM3 bus coupler  TM3 expansion modules  TM2 expansion modules

The following illustration is an example of an association:

NOTE: Do not mount a TM2 module before any TM3 module as indicated in the following illustration:

EIO0000003635 08/2020

Maximum Number of Modules

Each TM3 bus coupler supports up to:

Module type Maximum number of modules

TM2 7

TM2 - TM3 7

TM3 7 without transmitter and receiver.

NOTE: EcoStruxure Machine Expert and EcoStruxure Machine Expert - Basic software validate the configuration to the extent possible. However, although EcoStruxure Machine Expert may allow certain configurations, the maximum configuration populated by high energy consuming modules, coupled with the maximum distance allowable between the TM3 transmitter and receiver modules, may present bus communication issues in some environments. If this occurs, you will need to analyze the energy consumption of the modules chosen for your configuration, minimize the cable distance required by your application, and otherwise consider optimizing your choices.

 Use shielded cables for all fast I/O, analog I/O, and communication signals.

 Ground cable shields for all fast I/O, analog I/O, and communication signals at a single point  Route communications and I/O cables separately from power cables.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Multipoint grounding is permissible (and in some cases inevitable) if connections are made to an equipotential ground plane dimensioned to help avoid cable shield damage in the event of power system short-circuit currents.

NOTE: Surface temperatures may exceed 60 °C (140 °F). To conform to IEC 61010 standards, route primary wiring (wires connected to power mains) separately and apart from secondary wiring (extra low voltage wiring coming from intervening power sources). If that is not possible, double insulation is required such as conduit or cable gains.

EIO0000003635 08/2020

All connectors must be connected to Protective Extra Low Voltage (PELV) according to UL 610102-201 or IEC 60950 or Class 2 of NEC.

Rules for Removable Screw Terminal Block

The following tables show the cable types and wire sizes for a 5.08 pitch removable screw terminal block (I/Os and power supply):

The use of 75 °C (167 °F) wires with copper conductors is required.

FIRE HAZARD

Use only the correct wire sizes for the maximum current capacity of the power supplies.

Failure to follow these instructions will result in death or serious injury.

DANGER

Protecting Outputs from Inductive Load Damage

Depending on the load, a protection circuit may be needed for the outputs on the controllers and certain modules. Inductive loads using DC voltages may create voltage reflections resulting in overshoot that will damage or shorten the life of output devices.

CAUTION

OUTPUT CIRCUIT DAMAGE DUE TO INDUCTIVE LOADS

Use an appropriate external protective circuit or device to reduce the risk of inductive direct current load damage.

Failure to follow these instructions can result in injury or equipment damage.

EIO0000003635 08/2020 57

TM3 Bus Coupler Installation

If your controller or module contains relay outputs, these types of outputs can support up to 240 Vac. Inductive damage to these types of outputs can result in welded contacts and loss of control. Each inductive load must include a protection device such as a peak limiter, RC circuit or flyback diode. Capacitive loads are not supported by these relays.

RELAY OUTPUTS WELDED CLOSED

 Always protect relay outputs from inductive alternating current load damage using an

appropriate external protective circuit or device.

 Do not connect relay outputs to capacitive loads.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

AC-driven contactor coils are, under certain circumstances, inductive loads that generate pronounced high-frequency interference and electrical transients when the contactor coil is deenergized. This interference may cause the logic controller to detect an I/O bus error.

CONSEQUENTIAL LOSS OF CONTROL

Install an RC surge suppressor or similar means, such as an interposing relay, on each TM3 expansion module relay output when connecting to AC-driven contactors or other forms of inductive loads.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING

Protective circuit A: this protection circuit can be used for both AC and DC load power circuits.

 C represents a value from 0.1 to 1 μF.  R represents a resistor of approximately the same resistance value as the load.

EIO0000003635 08/2020

TM3 Bus Coupler Installation

Protective circuit B: this protection circuit can be used for DC load power circuits.

Use a diode with the following ratings:

 Reverse withstand voltage: power voltage of the load circuit x 10.  Forward current: more than the load current.

Protective circuit C: this protection circuit can be used for both AC and DC load power circuits.

 In applications where the inductive load is switched on and off frequently and/or rapidly, ensure

that the continuous energy rating (J) of the varistor exceeds the peak load energy by 20 % or more.

DANGER

FIRE HAZARD

Use only the correct wire sizes for the maximum current capacity of the power supplies.

Failure to follow these instructions will result in death or serious injury.

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not exceed any of the rated values specified in the environmental and electrical characteristics tables.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

EIO0000003635 08/2020

DC Power Supply Requirements

The TM3 bus coupler and the associated expansion modules require power supplies with a nominal voltage of 24 Vdc. The 24 Vdc power supplies must be rated Protective Extra Low Voltage (PELV) according to UL 61010-2-201 or IEC 60950 or Class 2 of NEC. These power supplies are isolated between the electrical input and output circuits of the power supply.

POTENTIAL OF OVERHEATING AND FIRE

 Do not connect the equipment directly to line voltage.

 Use only isolating PELV power supplies and circuits to supply power to the equipment

Failure to follow these instructions can result in death, serious injury, or equipment damage.

For compliance to UL (Underwriters Laboratories) requirements, the power supply must also conform to the various criteria of NEC Class 2, and be inherently current limited to a maximum power output availability of less than 100 VA (approximately 4 A at nominal voltage), or not inherently limited but with an additional protection device such as a circuit breaker or fuse meeting the requirements of clause 9.4 Limited-energy circuit of UL 61010-1. In all cases, the current limit should never exceed that of the electric characteristics and wiring diagrams for the equipment described in the present documentation. In all cases, the power supply must be grounded, and you must separate Class 2 circuits from other circuits. If the indicated rating of the electrical characteristics or wiring diagrams are greater than the specified current limit, multiple Class 2 power supplies may be used.

Power interruption

The TM3 bus coupler must be supplied by an external 24 V power supply equipment. During power interruptions, the TM3 bus coupler, associated to the suitable power supply, is able to continue normal operation for a minimum of 10 ms as specified by IEC standards.

When planning the management of the power supplied to the controller, you must consider the power interruption duration due to the fast cycle time of the controller.

There could potentially be many scans of the logic and consequential updates to the I/O image table during the power interruption, while there is no external power supplied to the inputs, the outputs or both depending on the power system architecture and power interruption circumstances.

UNINTENDED EQUIPMENT OPERATION

 Individually monitor each source of power used in the controller system including input power

supplies, output power supplies and the power supply to the controller to allow appropriate system shutdown during power system interruptions.

 The inputs monitoring each of the power supply sources must be unfiltered inputs.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

EIO0000003635 08/2020

Grounding the TM3 System

Overview

Due to the effects of electromagnetic interference, cables carrying fast I/O, analog I/O, and the fieldbus communication signals must be shielded.

UNINTENDED EQUIPMENT OPERATION

 Use shielded cables for all fast I/O, analog I/O, and communication signals.

 Ground cable shields for all fast I/O, analog I/O, and communication signals at a single point  Route communications and I/O cables separately from power cables.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

The use of shielded cables requires compliance with the following wiring rules:

 For protective earth ground connections (PE), metal conduit or ducting can be used for part of

the shielding length, provided there is no break in the continuity of the ground connections. For functional ground (FE), the shielding is intended to attenuate electromagnetic interference and the shielding must be continuous for the length of the cable. If the purpose is both functional and protective, as is often the case for communication cables, the cable must have continuous shielding.

 Wherever possible, keep cables carrying one type of signal separate from the cables carrying

other types of signals or power.

WARNING

TM3 Bus Coupler Installation

Protective Earth Ground (PE) on the Backplane

The protective earth ground (PE) is connected to the conductive backplane by a heavy-duty wire, usually a braided copper cable with the maximum allowable cable section.

EIO0000003635 08/2020 63

TM3 Bus Coupler Installation

Shielded Cables Connections

Cables carrying fast I/O, analog I/O, and the fieldbus communication signals must be shielded. The shielding must be securely connected to ground. Fast I/O and analog I/O shields may be connected either to the functional ground (FE) or to the protective earth ground (PE) of your TM3 expansion module. The fieldbus communication cable shields must be connected to the protective earth ground (PE) with a connecting clamp secured to the conductive backplane of your installation.

ACCIDENTAL DISCONNECTION FROM PROTECTIVE GROUND (PE)

 Do not use the TM2XMTGB Grounding Bar to provide a protective earth ground (PE).  Use the TM2XMTGB Grounding Bar only to provide a functional ground (FE).

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Rotary Switch

Overview

The two rotary switches located on the front panel of the TM3 CANopen bus coupler are used to set the CANopen bit rate and CANopen NodeID.

Default values on the rotary switches are:

 0 for TENS  0 for ONES

(TENS) Set the bit rate/represents the tens numbered 0 to 120. (ONES) Authorize to set the bit rate when set to not used position/represents the numbers 0 to 9.

Setting the Bit Rate

The TM3 CANopen bus coupler detects a new bit rate selection by the rotary switches only during power up. The bit rate is written to non-volatile memory.

Set the ONES rotary switch to any of the unnumbered positions (not used) to set a particular bit rate with the TENS rotary switch.

NOTE: Any modification of the rotary switch position during operational mode is not taken into account. The ERR LED flashes red. See status LEDs

Bit rate can also be set and verified via the web server. For more information, refer to the Modicon TM3 Bus Coupler Programming Guide.

Setting the CANopen Address

The TM3 CANopen bus coupler address (from 1 to 127, decimal) is configured using the two CANopen address settings rotary switches.

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not use an address outside of the specified range (from 1 to 127).

Failure to follow these instructions can result in death, serious injury, or equipment damage.

To reset the CANopen bus coupler, remove power and provide a correct address before reapplying power to the bus coupler.

Set the CANopen address using the TENS rotary switch to represent the hundreds and tens digit and the ONES rotary switch to represent the units digit.
