1 PLC Input/Output Modules

Introduction 1.1 Digital and Analogue Signals

Digital input/output signals are switching signals, a 1 or a 0.

Analogue signals, there are two kinds of voltage signals or current signals, generally signals transmitted by the transmitter, such as pressure transmitter to detect the pressure of the water pipe, will output a 4-20ma or 0-10V analogue signal to the PLC, the PLC for data processing.

Switching input point (DI), processing switching input signal.

Analogue input point (AI), processing analogue input signals (0-20 MADc, 0-5VDC).

Resistance signal (including RTD) input point, processing RTD or general resistance signal.

High-speed pulse input point, processing high-speed pulse signals.

Voltage (including thermocouple) input point, processing voltage input or thermocouple signals.

Ethernet communication

Application example – mesh copper/optical fibre ring

Applications

The line transformer 500LTD01 is designed for FSK channels in the 50 Bd to 2400 Bd range.

It is used to isolate and protect the RTU500 series modems 23WT23. 23WT25 and 560FSM10 from remote control lines.

In addition, it can be connected to other data terminal equipment.

It is optimised for wire-first communication with a frequency range of 300 Hz to 3400 Hz and a line impedance of 600 ohms for the above modems.

All three types of modems allow high-resistance interleaving on lines such as party lines and multisplit lines.

This is because the line transformer has no additional load on the line.

In configurations using full duplex communication channels, two line transformers are required, one for the transmit direction and the other for the receive direction.

Features

The line transformers can withstand isolation voltages of:

> 10 kV, 50 Hz, 10 sec.

The SDSL port can be used to connect copper stations with a maximum distance of 20 km (0.8 mm diameter).

Depending on the SFP modules fitted, the device can achieve spans of up to 40 km over fibre-optic cables.

The switch provides a redundant topology via (fast) spanning tree protocol.

For documentation purposes, the Ethernet ports are labelled 1 to 4. The SDSL ports are connected via snap-in connectors.

There is no specific uplink port. All ports are functionally identical.

The link and speed status of each Ethernet port and SDSL port is indicated by the status indicators on the right (see ‘Connectors and Indicators’).

SFP-related indicators are located on the left.

The switch learns the Ethernet address by analysing incoming frames and stores it in a lookup table

(up to 2048 entries), which is used to forward the frame to the correct port only.

If a broadcast or multicast frame is received, or if the destination address is not found in the lookup table, the

then the received frame is forwarded to all ports other than the receiving port.

If an incoming frame with a specific source address does not refresh the entry in the lookup table, the entry is aged out for a certain period of time.

then it is aged out for up to 304 seconds (default, configurable).

With respect to IEEE 802.1Q VLAN frames, the switch can be configured in VLAN or transparent mode.

In transparent mode, the switch does not change any frames or frame TAGs;

In VLAN mode, the switch can be configured to support multiple applications, such as trunks or access ports.

The switch can support quality of service if it uses IEEE 802.1p-compliant frame formats.

The switch can divide frames into up to four queues, which can be configured as priority-based queues or weighted fair queues.

The 560NMD11 uses a wide-range power supply and operates from 24 to 60 V. The switch itself, the Ethernet ports, and the Ethernet ports can be connected to the switch.

The switch itself, the Ethernet ports, as well as the SDSL connections, RS-232 interfaces, and SFP transceivers are hot-swappable.

Applications

The 560NMD01 Top Hat DIN-Rail Appliance is a managed Layer 2 switch.

It provides four Fast Ethernet RJ45 ports with automatic MDI/X (Automatic Cross Detection and Correction) and a 2-wire SDSL interface.

The SDSL interface can be used to connect sites with distances of up to 20 km (copper cable, 0.8 mm diameter).

Thanks to the (fast) Spanning Tree Protocol, the switch enables a redundant topology.

For documentation purposes, Ethernet ports are labelled with numbers 1-4. There are no special uplink ports. All ports are functionally identical.

The SDSL ports are externally connected via backplane or expansion connectors. The connection (link) and speed status of all Ethernet and SDSL ports is indicated by LEDs on the front panel.

The switch “learns” Ethernet addresses by analysing received frames.

The addresses learned in this way are stored dcs-sis.com in the address table (up to 2048 entries) and are used to forward the frames to the correct interface.

Frames are forwarded to all interfaces only if they are received with a wide or multicast address, or if the destination address is not found in the address table.

If an entry in the address table is not acknowledged by the corresponding received frame, it is deleted after a maximum of 304 seconds (default).

IEEE 802.1Q-compliant VLAN configuration is supported. Frames can be transparently forwarded or assigned to (access or trunk) VLANs.

The switch can support quality of service if IEEE 802.1p-compliant frame formats are used. The switch can divide outbound frames into up to four priority-controlled queues.

The device has a wide-range power supply, requiring a voltage between 24 and 60 V. The switch can be used with a wide range of power supplies.

The Ethernet interface, SDSL, RS232 (Con 0) and the expansion bus interface (Ext) can be plugged in during operation (hot-swap).

Connectors and indicators

The 560NMD01 device provides four equivalent Ethernet interfaces with RJ-45 connectors, an SDSL interface and an RS232 interface that are

for configuration and transfer of serial data. Each RJ-45 port can be connected via Cat.3 (10Mbps) or Cat.5 (100Mbps) network cable.

for internal communications up to 100 metres. Support for MDI/X means that crossover Ethernet cables are not required.

The SDSL interface can be connected via a two-wire copper cable. The maximum connection distance is 20 kilometres using a 0.8 mm diameter copper cable with a transmission rate of 192 kbps.

Depending on the distance, the transmission rate can be increased to a maximum of 11 Mbps.

The status of all interfaces can be monitored by two LEDs. For Ethernet interfaces, these are located on the lower and upper part of the RJ45 socket.
