Operation

Unlike an Ethernet hub, which broadcasts all messages received out all ports, the DRL-7xx series route Ethernet messages to the appropriate port. In other words, it prepares the network for optimal bandwidth conditions, reduces the number of collisions.

The DRL-7xx series supports 10BaseT (10 Mbps) or 100BaseT (100 Mbps) on the M-12 ports. Each port, independent of the others, will auto-negotiate the speed and duplex mode. This allows both 10 Mbps (full or half duplex) and 100Mbps (full or half duplex) devices to be connected to the same DRL-7xx series Switch.

Performance Specifications

The performance specifications are as follows. For complete technical specifications, including switch dimensions, refer to Appendix A.

Overview

IP67 Switches can be powered from the same DC source that is used to power your I/O devices. 9 to 36 VDC needs to be applied across the +24VDC1 and Common (0v) terminals.

The third terminal (PE) should be tied to panel or chassis ground, first making sure the possible grounding point is free of electrical noise.

To reduce downtime resulting from power loss, the switch can be powered redundantly by connecting a second power supply to the +24VDC2 terminal and the Common terminal (0v).

Warning

Equipment should be installed in accordance with local and national country wiring codes.

Power-supply Redundancy

IP67 switches can operate from either +24VDC1 or +24VDC2. When using power supply redundancy, two different power supplies shall be used. If one of these power supplies would fail, the DRL-7xx Industrial Switch will continue to operate transparently.

Daisy-Chaining Module’s Power-supply

The DRL-78x has 2 power ports to allow daisy chaining power from one device to another. This feature could be used to power additional I/O blocks or switches without power tees or taps.

Warning

While daisy-chaining power between modules, the total current (amps) needs to be calculated for the whole chain and that value must not exceed 8 A (DRL-780, DRL-781) or 4 A (DRL-782) per power-supply pin, either +24VDC or 0V terminal. The power requirements of the DRL-78x also need to be considered in power budgeting (refers to Fig. 10).

Overview

Switches provide connections to standard Ethernet devices, such as PLCs, Ethernet I/O and industrial computers. These devices are connected to the switch using standard M12 communication ports.

Figure 7 - Switch Connections

M12 Ethernet Wiring

Use data-quality (not voice-quality) twisted pair cable, rated category 5 (or better), with M12 D-Coded connectors. For best performance, use shielded cable. Straight through or crossover M12 cable can be used, regardless of the device the switch is to be connected to, as all the DRL-700 Series Switches are capable of auto-mdi/mdix-crossover detection.

The M12 Ethernet port connector bodies are metallic and are connected to the PE connection point (either terminal or screw). Therefore, shielded cables may be used to provide further protection.

To prevent ground loops, the cable shield should be tied to the metal connector body at one end of the cable only. For increased reliability, electrical isolation is also provided on the Ethernet ports.

Ethernet Cable Length

The maximum cable length for 10BaseT / 100BaseTx is typically 100 meters (328 ft.).

Duplex Operation

All Ethernet ports will auto-sense for Full or Half duplex operation.

Verifying Connectivity

When all Ethernet connections have been made, check the LEDs corresponding to the ports with devices connected. Each port that is in use, the LED should be ON or blinking. If a port LED is off, check for connectivity problems between that port and the network device connected to it. In addition, the LED color should indicate the speed your device is connected at (for more details, refer to Chapter 2, LED Indicators).

IP67 Industrial Ethernet Switches Hardware Reference Guide

Switch Features

Below is a brief description of the features of the IP67 Industrial Ethernet Switches DRL-7xx series.

10BaseT and 100BaseTx Auto-Negotiation

Standard Ethernet (10BaseT) has a maximum speed of 10 Mbps. Fast Ethernet (100BaseTx) has a maximum speed of 100 Mbps. The M12 ports on the switches automatically select the appropriate speed.

1K / 8K MAC Addresses with Automatic Learning, Aging and Migration

Each Ethernet device inserts its unique “MAC” address into each message it sends out. The port on the switch used for a given MAC address is automatically learned when a frame is received from that address. Once an address is learned, the switch will route messages to the appropriate port only, instead of broadcasting messages out all ports, like a hub. A timestamp is also placed in memory when a new address is learned. This timestamp is used with the aging feature, which will remove unused MAC addresses from the table after 300 seconds. If a device moves, the associated port on the switch will be changed (migrated) as needed. Up to 1,024 MAC addresses can be stored and monitored at any time on the DRL-750 and 8,192 on the DRL-78x.

Auto-Crossover (Auto-MDI/MDI-X)

The switch ports will automatically detect the cable type (straight-thru vs. cross-over) and reconfigure accordingly.

Auto-Sensing or Auto-Negotiating Speed

The switch ports will auto-negotiate with the connected device to determine the optimal speed (10 Mbps vs. 100 Mbps).

Backoff Operation

The switches will drop a packet after 16 consecutive retransmit attempts.

Document Edition: 1.1, Document # 715-5000

Page 26

Hardware Reference Guide IP67 Industrial Ethernet Switches

Back Pressure for Half-Duplex

The switches will apply “back pressure” when necessary with half-duplex operation. This will reduce congestion on busy networks.

Buffering

SRAM is used for buffering the messages. The DRL-750 has an internal 512 Kbit SRAM for buffering, and the DRL-78x have 1 Mbit.

Unmanaged Operation

The switches require no supervisory processor to operate properly.

Flow Control

The switches automatically support flow control frames on both transmit and receive sides.

Forwarding

The switches support store and forward mode. They forward messages with known addresses out the appropriate port only. Messages with unknown addresses, broadcast messages, and multicast messages get forwarded out all ports, except the source port. The switches will not forward error packets, 802.3x pause frames, or “local” packets.

Full/half-Duplex Operation

The switches’ ports support both full and half duplex flow control.

Illegal Frames

Illegal frames, as defined by IEEE 802.3, will be dropped. This includes short frames, long frames and FCS error frames.

Switch Features

Page 27

IP67 Industrial Ethernet Switches Hardware Reference Guide

IEEE 802.3 Compliant

The switches abide to the IEEE 802.3 standard for 10BaseT and 100BaseTX Ethernet communications.

Late Collision

If a packet experiences collisions after 512 bit times of transmission, it will be dropped.

Latency

The typical latency of a message is 5 microseconds or faster. The latency is the time it takes a message to be routed internally to a switch from one port to another.

Plug and Play

This means that most of the switches’ functions or features are automatic and that no optional parameters need to be set. Just plug in your Ethernet cables, apply power, and the unit will immediately begin to operate.

Protocol Independent

The switches simultaneously support all popular Ethernet protocols and networks, such as TCP/IP and NetBEUI that run over standard Ethernet (IEEE 802.3).

Overview

The following chapter highlights some basic cabling rules that must be implemented to achieve reliable operation of your network. Industrial networks must be robust enough to avoid costly process downtime. Every part of the design should be carefully selected to perform in a harsh environment over its lifetime. Specifically Devices, Connectors and Cables should be chosen based on their behavior regarding:

- Vibrations

- Climatic stresses

- Electric noise

- Chemical aggression

Cable Categories

Cable Routing

As a general guide:

- Cables of the same category shall be routed together and never cross each other.

- If crossing cables is necessary it should be done at right angles to reduce any negative

impact. This is especially important when crossing communication and power wires.

- When running disturbing cables (class 1 and 2) parallel they should be kept apart from

Data cables with a minimum separation of 0.30m to limit capacitive and radiated coupling.

- All cables should be routed in metal cableways.

Bonding and Grounding

Proper bonding and grounding of your equipments is a key point to meet safety regulations. It will also help in reducing EMI and ground noise effects.

The PE on power connector needs to be connected only when no earth connection is available. In order to avoid ground loops, it is recommended that the one of the Protected Earth connection points (PE in Power connector OR FE screw to the chassis) be grounded.

Connecting the DRL-78x to earth requires a bonding lead with an M3 ring terminals. See picture below for details.

The DRL_750 can be grounded through its top right or bottom left holes using either a bonding lead with an M3 ring terminal or directly to an earthed chassis with M3 screws.

Data Cable Shielding

The IP67 Industrial Ethernet Switches are designed for mounting directly on machine frames. This kind of environment, subject to high electrical noise, requires usage of suitable cable type. Shielded Cables (STP) shall be selected for this type of application, as they provide good noise immunity to the whole system.

Conforming to IP67

To ensure the device is IP67 rated, all connectors (Power supply, Ethernet ports) need to be connected to an IP67 cable, or terminated with the appropriate caps.

Planning your installation

Always use cables/connectors suitable for your application. It’s important to go with cables/connectors designed for an industrial environment.

Caution

A DC power source that complies with the Safety Extra Low Voltage (SELV) requirements of UL 1950, CSA C22.2 No. 950-95, EN 60950, and IEC 60950 must be used when powering the DRL-700 Series of IP67 Industrial Ethernet Switches.
