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 www.cniacs.com 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.

OVERVIEW

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.cniacs.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.

Ethernet communication

Application example – mesh copper/optical fibre ring

Isolated line transformers for current isolation in transmission lines

Frequency range: 0.3 kHz to 3.4 kHz

Ratio 1:1

Insulation test voltage 10 kV

Optimised for line impedances of 600 Ω

Insulation resistance: 10000 MΩ at 500 V

Applications

The line transformer 500LTD01 is designed for www.cniacs.com 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.

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.
