1 For your safety

Read this user manual carefully and keep it to hand for future reference.

1.1 Labeling of warning notes

For your safety

This symbol indicates hazards that could lead to personal injury. There are three signal words indicating the severity of a potential injury.

DANGER

Indicates a hazard with a high risk level. If this hazardous situation is not avoided, it will result in death or serious injury.

WARNING

Indicates a hazard with a medium risk level. If this hazardous situation is not avoided, it could result in death or serious injury.

CAUTION

Indicates a hazard with a low risk level. If this hazardous situation is not avoided, it could result in minor or moderate injury.

This symbol together with the NOTE signal word alerts the reader to a situation which may cause damage or malfunction to the device, hardware/software, or surrounding property.

Here you will find additional information or detailed sources of information.

1.3 Safety notes

Please note that, in combination with antennas, the maximum permissible transmission power may be exceeded. Please set the transmission power via the software.

The use of antennas with a gain greater than 6 dBi may require that the transmit power be reduced from the default setting of 30 dBm. Regulations limit the equivalent isotropicallyradiated power (EIRP) to 36 dBm. The EIRP may be calculated as the transmit power (Pt) minus any cable loss (Lc) plus the antenna gain (Ga).

EIRP = Pt - Lc + Ga

For example, in the case of a 12 dBi antenna used with a cable run with a 4 dB loss, the transmit power must be reduced to 28 dBm or less such that the EIRP does not exceed 36 dBm.

The PSI-CONF configuration and diagnostic software can be used to configure the transmit power.

Operation of the wireless system is only permitted if accessories available from Phoenix Contact are used. The use of other accessory components may invalidate the device approval status

Using the DIP switches on the front, you can configure the inputs signals (0 mA ... 20 mA or 4 mA ... 20 mA). Any changes in the setting of the DIP switches will be directly applied.

In PLC/Modbus RTU mode, the setting of the input signals is evaluated for error diagnostics. With the setting 4 mA ... 20 mA, it is, for example, possible to detect an open circuit.

3.2 RAD-PT100-4-IFS - extension module with four temperature inputs

Use the I/O extension modules in connection with the RAD-900-... wireless module, firmware version 1.40 or later. You can update the firmware free of charge using the PSI-CONF software, Version 2.04 or later.

The firmware and software can be found on the Internet at

The analog RAD-PT100-4-IFS I/O extension module has four Pt 100 inputs for temperatures between -50°C ... +250°C. The Pt 100 inputs T1 ... T4 can be mapped to the analog outputs I1/U1 ... I4/U4 of the RAD-AO4-IFS extension module. All the inputs are electrically isolated from one another, from the supply voltage, and from the remaining electronics.

Pt 100 resistance thermometers can be connected to the RAD-PT100-4-IFS I/O extension module. The thermometers change their resistance depending on the temperature. The Pt 100 input signals are acquired by the RAD-PT100-4-IFS and can be mapped to proportional, analog voltage or current signals of the RAD-AO4-IFS output module.

Example: At the Pt 100 input, a current of 0 mA or a voltage of 0 V is released at the output module at a temperature of -50°C. At the Pt 100 input, a current of 20 mA or a voltage of 10 V is released at the output at a temperature of 250°C.

3.2.1 Connecting sensors

You can connect 2-wire or 3-wire sensors to the extension module. Observe the measuring errors depending on the different measuring methods.

2-wire connection technology

2-wire connection technology is the most cost-effective connection method. The temperature-related voltage is not directly measured at the sensor and therefore falsified by the two cable resistances R measurement to become useless. Please observe the diagrams in Section “Measuring errors using 2-wire connection technology” on page 22.

With 2-wire technology, you need an insertion bridge between terminals x.2 and x.3.

3-wire connection technology

With 3-wire connection technology, the temperature-related voltage is measured several times. Corresponding calculations additionally reduce the effect of the cable resistance on the measurement result. The results are almost as good as those achieved using the 4-wire technology.

The cable resistances R

at the terminals +I and -I must have the same value. This allows

you to subtract the established cable resistance from the measurement result and to get the Pt 100 platinum resistance value.

4-wire connection technology

The RAD-PT100-4-IFS does not support the 4-wire connection technology.

• If you want to use a 4-wire sensor, only connect three of the four wires.

• The fourth wire should be left unwired. Otherwise there will be a different resistance in

the +I and -I cables owing to the parallel connection of two cable resistances.

Make sure that the cable resistance and therefore the measuring error is as low as possible.

• Use sensor cables that are as short as possible.

• Avoid conductor cross sections smaller than 0.5 mm

The temperature has only a small influence on the cable resistance.

You can calculate the cable resistance as follows:

Due to there being two cable resistances in the measuring system, the value must be doubled. Using the average temperature coefficient α = 0.385 Ω/K for Pt 100, the absolute measuring error in Kelvin can be determined for platinum sensors according to DIN standards.

3.2.3 Shielding of the sensor cables

Always connect the analog sensors using shielded, twisted pair cables (e.g., LiYCY, TP 2 x 2 x 0.5 mm

• Immediately following entry in the control cabinet, connect the cable shields to the

corresponding shield connection clamps.

Please note that the electrical isolation between the channels may no longer occur when connecting the shields. The isolating distances between the individual channels need to be re-evaluated after connecting the shields. The distances between the individual wires and the common shields are crucial in this respect.

3.5.4 Functions in pulse counter mode

The counter state can only increase consecutively. When the maximum counter limit of 4,294,967,295 is reached, the counter is automatically set back to 0. In addition, you can manually reset the counter states in three different ways:

Reset counter state via power up

• Disconnect the device power supply and then reconnect the voltage.

Reset counter state via the Modbus RTU register

• Reset the counter states via Modbus RTU as follows:

– DI1: bit 0 = 1 (register 40xx1) – DI7: bit 1 = 1 (register 40xx1)

3.7 RAD-DO8-IFS - digital extension module with eight outputs

The firmware and software can be found on the Internet at

The digital RAD-DO8-IFS I/O extension module processes up to eight digital output signals that are switched via transistor outputs. The eight outputs are arranged in two groups of four outputs each with a common electrical supply. The two output groups are electrically isolated from one another, from the supply voltage, and from the electronics.

Since the DO1 ... DO4 and DO5 ... DO8 output groups are electrically isolated, the digital outputs must be externally supplied (see Figure 3-33).

• The DO1 ... DO4 outputs are supplied via:

– Terminal 1.1 (12 V DC ... 30.5 V DC) – Terminals 1.2/1.3 (GND)

• The DO5 ... DO8 outputs are supplied via:

– Terminal 6.1 (12 V DC ... 30.5 V DC) – Terminals 6.2/6.3 (GND)

I/O data mode

Figure 5-1 I/O data mode

By default, all wireless modules are in the I/O data mode. For simple I/O-to-I/O applications with extension modules, you can easily set the addresses using the thumbwheel. You can therefore establish a wireless connection to other wireless modules without any programming effort (see “Setting the address of the wireless module via the thumbwheel” on page 71 and “Setting the address of the extension modules via the thumbwheel” on page 80).

Serial data mode (RAD-900-IFS only)

Figure 5-2 Serial data mode

In serial data mode, multiple controllers or serial I/O devices are networked easily and quickly using wireless technology. In this way, serial RS-232 or RS-485 cables can be replaced.

Each wireless module must be configured using the PSI-CONF software (from page 74 onwards).

Configuration and startup

The I/O data of the extension module and the diagnostic data is stored in the internal Modbus memory map of the wireless module. Each wireless module with I/O extension modules has its own Modbus address. In addition, the diagnostic data from all wireless devices can be read from the master wireless module.

Each wireless module must be configured using the PSI-CONF software (from page 74 onwards).

5.3 Setting the address of the wireless module via the

thumbwheel

Set the desired station address with the yellow thumbwheel on the wireless module. There must be one master (RAD ID = 01) and at least one repeater/slave (RAD ID = 02 ... 99) in a network.

Unique addressing is required in a network. If two wireless modules have the same address in a network, the network will not function properly.

Setting the address via the thumbwheel has priority over setting the address via the PSI-CONF software.

After making any change to the module address, press the SET button for one second to apply the setting.

The following settings can be made using the yellow thumbwheel:

5.4 Configuration via CONFSTICK

WARNING: Explosion hazard when used in potentially explosive areas

Do not insert or remove the CONFSTICK in a potentially explosive atmosphere.

By default upon delivery, all wireless modules have the same network ID and the same RF band. Using a configuration memory (CONFSTICK), you can configure a unique and secure network without the need for software.

The CONFSTICK is used as a network key. Its network address (network ID) is unique and cannot be assigned via the PSI-CONF software. Only wireless modules with the same network ID are allowed to connect with each other.

Each individual network device must be configured. Only one CONFSTICK is needed for all wireless modules in the network. After configuration, remove the CONFSTICK from the wireless module.

3827_en_B PHOENIX CONTACT 71/138

Page 74

RAD-900-...

In addition, the CONFSTICK contains a preset frequency band (RF band). An RF band is a group of frequencies compiled of individual frequencies of the entire 900 MHz band. Different RF bands use different frequencies.

In order to operate several Radioline wireless systems, you should select different RF bands.

Set different RF bands between 1 ... 8 and network IDs between 1 ... 127 using the PSICONF software (see page 75).

After reading an existing network project or creating a new project, the network settings can be modified under “Individual Settings”. The wireless network can be optimized and adapted to your special requirements. When moving the mouse over the individual network parameters, you obtain a short description under “Help”.

If several wireless systems are operated parallel and in close proximity, you are required to set the RF band and the network ID. These parameters can be set via the PSI-CONF software or by using a CONFSTICK (see “Configuration via CONFSTICK” on page 71).

5.6.2 Data transmission speed of the wireless interface

The range is an important parameter in industrial wireless applications, especially in outdoor applications. Even in cases where long ranges do not have to be covered, good receiver sensitivity enables transmission in harsh outdoor conditions, e.g., when there is no direct line of sight.

The receiver sensitivity determines the signal amplitude which can just about be received by the wireless module. The lower the data transmission speed of the wireless interface, the higher the receiver sensitivity and thereby the range.

Adjust the data transmission speed of the wireless interface to the respective application using the PSI-CONF software (default setting = 125 kbps).

5.9 Startup time of the wireless station

Once a wireless station has been started (power “ON”), the wireless module will take 15 seconds to be ready for operation. Each linked I/O extension module increases the startup time by 3 seconds.

Startup time of a wireless station = 15 seconds + (number of I/O modules x 3 seconds)

Accordingly, a complete wireless station with 32 I/O extension modules requires a startup time of 111 seconds. Only after this period of time has elapsed is the wireless station ready for operation.

Setting telegram pauses, based on the example of Modbus/RTU

A frame is also referred to as a telegram. The length of the transmission pause between the telegrams depends on the set data rate. The beginning and end of a telegram is recognized by means of a time condition. A pause of 3.5 characters means that the telegram is complete and the next character is to be interpreted as the slave address. A telegram must therefore be sent as a continuous data flow. If there is an interruption of more than 1.5 characters within a telegram, the data will be discarded by the receiver.

If the master is not able to transmit the successive characters quickly enough and the communication is aborted, you must increase the minimum pause time (T

FrameEnd

) between the individual characters of a telegram. Frames with a length of 1480 characters can be transmitted by the Radioline wireless system.

• In order to adapt data transmission to other protocols, it is possible to adapt the

parameters. Set the interface parameters under “Individual

Addressing I/O extension modules and RAD-900-DAIO6 with Modbus RTU

9 Addressing I/O extension modules and RAD-900-DAIO6

with Modbus RTU

9.1 Modbus function codes

In the Modbus protocol, the function codes define which data is to be read or written. With a single request, the registers 1 ... 123 can be read or written.

Table 9-1 Supported Modbus function codes

Code number Function code Description

fc 03 Read Holding Register Read process output data

(address area 40010 ... 40999)

fc 04 Read Input Register Read process input data

(address area 30010 ... 30999)

fc 16 Write Multiple Registers Write multiple output registers word by word

Other function codes exist in the Modbus protocol, but they are not supported.

9.2 Modbus protocol

The data is transmitted using the Modbus/RTU (Remote Terminal Unit) protocol. Communication takes place according to the master/slave method. The Modbus master initiates communication with a request to the slave. If the slave detects that its address has been accessed by the master, the slave always sends a response.

Only the master is able to initiate communication. The slaves are not able to initiate communication and do not communicate with each other.

The connected extension modules write the analog or digital input and output values to an internal register. The Modbus master (e.g., a PLC) can read the individual registers using the Modbus address of the slaves. The data to be transmitted is always included in a defined frame. The frame is referred to as telegram.

The Modbus protocol defines the format of the telegrams. If an error occurs when the telegram is received on the slave side, or if the slave is unable to carry out the master request, an error telegram is sent back to the master.

3827_en_B PHOENIX CONTACT 97/138

Page 100

RAD-900-...

Request from master

The function code in the request informs the addressed slave which action is to be carried out. The address and data bytes contain all additional information that the slave requires in order to carry out the action.

Example: The master uses function code 03 to request the slave to read the process output data and send its content to the master. The data and address bytes need to include the following information: from which register reading should start and how many registers should be read. Using the CRC check value, the slave is able to detect whether the complete telegram has been received.

Response from slave

If the response from a slave is valid, the function code will match the request from the master. The address and data field contains the data recorded by the slave (e.g., register values).

The function code is modified in the event of an error. The address and data field then contains a code that describes the error. By using the CRC check value, the master is able to determine whether the telegram content is valid or not.

The Modbus/RTU telegrams are separated by telegram pauses known as end-of-frame times. The end-of-frame time must be at least 3.5 x as long as the time required for one transmitted character. The end-of-frame time cannot be changed.
