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 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. www.honeywell-diver.com 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.

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.

There are also communication functions for data exchange with the host computer or control subordinate controller instrument driver

1.2 Digital and analogue input modules

According to the different field input signals, the input module can be divided into switching input module and analogue input module.

The function of the switching input module is to convert various switching signals into TTL standard signals required by the CPU. Depending on the type of input power supply, they can also be DC input modules and AC input modules. The input signals are converted to TTL (5V) standard signals by photocoupling after voltage division, current limiting, and filtering.

The function of the analogue input module is to convert www.honeywell-diver.com changing analogue signals such as temperature, flow, current, voltage, etc. into a number of digital signals which can be processed by the CPU. The analogue input circuit is generally composed of operational amplifier conversion, mode conversion (A/D), and optoelectronic isolation.

PLC input and output module types: digital input DI, digital output DO, analogue input AI, analogue output AO.

Digital inputs and outputs are generally 24V.

There are two types of analogue and four types of analogue. The two types are voltage type and current type. Voltage types are 0-10V and -10 to 10V. current types are mainly 4-20MA, 0-20MA. then the module converts the analogue to +32767~-32768 numbers through A/D conversion, and then implements the control.

The function of the signal template is to convert various process I/O signals. A variety of signal inputs are converted to digital quantities for easy recognition, processing and analysis by the PLC. Outputs are converted to analogue to a variety of regulatory mechanisms to perform, or the output is converted to a 2-bit do-it-yourself quantity to control a number of devices, such as start-stop, on and off

1.3 Digital Input/Output Module

The switching input module is a processing module that transfers external control signals or field detection signals to the PLC CPU. External signals are generally buttons, proximity switches, travel switches, etc.

Output module is the PLC according to the input module input signals and internal logic programming logic for processing, processing results out of the switching output will be the output module of the high and low level signals, drive the external intermediate relays, contactors, indicators, solenoid valves and other components, so that the external equipment to carry out the corresponding action

Remote Terminal Unit

Connectivity and Setup

Modem 560FSM10

Operation

The 560FSM10 modem is a CCITT V.23 modem with snap-in DIN rail mounting.

The V.23 uses the frequency shift keying (FSK) method. The modem operates in both 2-wire and 4-wire connections.

The operating mode is set by a 12-fold DIP switch. Figure 1 shows the front view of the modem with the components described in the next chapter from top to bottom.

The power connector X1 consists of three terminals for connection to the supply voltages shown in Table 1.

The PE pin must be connected to ground at the installation. The power indicator lights up when power is supplied.

The RJ45 connector X2 forms the RS232-D interface with the signals in Table 2. If the modem is connected to a communication device, the

If the modem is connected to a communication device, an adapter cable must be used to connect the pairs of lines in Table 2.

The RTS indicator lights up when the end device requests to send via the modem.

The DCD indicator lights when the 560FSM10 detects a carrier signal on the line interface. The CTS indicator lights when a carrier is being established.

CTS will be set at the same time. The 20-30ms transmit delay time must be adjusted in the CMU settings.

DIP switch S1 determines the operating mode of the modem. Switch C-1 is reserved for future use.

C-2 establishes a permanent carrier on the line, which is useful in a four-wire full-duplex connection. Table 3 summarises the above carrier modes.

Switch 2-W is used to distinguish between two-wire and four-wire operation of the modem, as shown in Table 4.

In two-wire mode, X3-1 and X3-2 form the terminal NF1 for transmit and receive.

In four-wire mode, X3-1 and X3-2 form transmitter terminal NF1 and X3-3 and X3-4 form receiver terminal NF2. as can be seen in Table 5.

The next three switches belong to the transmitter amplitude (see Table 6). In www.honeywell-diver.com longer multi-distribution line configurations, the

the centre station modem requires a high amplification factor to receive the signal from the last modem.

In this case, the transmission level of the central station modem can be reduced by 20 dB using the -20 dB switch.

This is done to avoid overloading the receiver of the central station modem. To compensate for the low-pass characteristics of the transmission line

The amplitude of the upper transmission frequency can be increased by 20%, 40% and 60%. If both the 20% and 40% switches are “off”, the amplitude will not increase.

The 560FSM10 has five predefined receiver amplification levels: 0 dB, 10 dB, 20 dB, 30 dB, and 40 dB.

They are set by switches 10 dB to 40 dB (see Table 7).

DIP switches T-T and T-R are turned on when the 560FSM10 is terminated with line impedance.

This is usually the case at both ends of the line. If the modem is connected as a party line between the two ends of the

then these DIP switches must be “off” (see Table 8.) The T-T end connects to the low frequency (LF) line NF1. consisting of terminals X3-1 and X3-2.

T-R terminates to receiver pair NF2 in a four-wire configuration, consisting of terminals X3-3 and X3-4.

The low-frequency signal transformer of the 560FSM10 modem is designed to meet communication line isolation conditions up to 3 kV.

To achieve a higher level of safe electrical isolation between the modem and the communication line, an additional, separate low-frequency signal transformer is required (see Figure 2).

The selected polarization voltage should be reasonably constant regardless of whether the system is operating without or with faults.

Phase-directed overcurrent

Phase-directed detection requires the determination of whether the current flow in each phase is forward or reverse, depending on the connection of the phase sources, the selected MTA angle, and the voltage and current phases.
