A Warning contains information, which is essential for avoiding a safety hazard.

A Caution contains information, which is necessary for avoiding a risk of damage to the product or other equipment.

A Note contains information, which helps to ensure correct operation of the product.

1.2 Important safety information. Hazards. Competence of designers and installers

This guide applies to products which control electric motors either directly (drives) or indirectly (controllers, option modules and other auxiliary equipment and accessories). In all cases the hazards associated with powerful electrical drives are present, and all safety information relating to drives and associated equipment must be observed.

Specific warnings are given at the relevant places in this guide.

Drives and controllers are intended as components for professional incorporation into complete systems. If installed incorrectly they may present a safety hazard. The drive uses high voltages and currents, carries a high level of stored electrical energy, and is used to control equipment which can cause injury. Close attention is required to the electrical installation and the system design to avoid hazards either in normal operation or in the event of equipment malfunction. System design, installation, commissioning/ start-up and maintenance must be carried out by personnel who have the necessary training and competence. They must read this safety information and this guide carefully.

1.3 Responsibility

It is the responsibility of the installer to ensure that the equipment is installed correctly with regard to all instructions given in this guide. They must give due consideration to the safety of the complete system, so as to avoid the risk of injury both in normal operation and in the event of a fault or of reasonably foreseeable misuse.

The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent or incorrect installation of the equipment.

1.4 Compliance with regulations

The installer is responsible for complying with all relevant regulations, such as national wiring regulations, accident prevention regulations and electromagnetic compatibility (EMC) regulations. Particular attention must be given to the cross-sectional areas of conductors, the selection of fuses or other protection, and protective ground (earth) connections.

SI-INTERBUS User Guide 7 Issue Number: 1

CMD tool

Glossary

of terms

This guide contains instructions for achieving compliance with specific EMC standards.

All machinery to be supplied within the European Union in which this product is used must comply with the following directives:

2006/42/EC Safety of machinery.

2014/30/EU: Electromagnetic Compatibility.

1.5 Electrical hazards

The voltages used in the drive can cause severe electrical shock and/or burns, and could be lethal. Extreme care is necessary at all times when working with or adjacent to the drive. Hazardous voltage may be present in any of the following locations:

• AC and DC supply cables and connections

• Output cables and connections

• Many internal parts of the drive, and external option units

Unless otherwise indicated, control terminals are single insulated and must not be touched.

The supply must be disconnected by an approved electrical isolation device before gaining access to the electrical connections.

The STOP and Safe Torque Off functions of the drive do not isolate dangerous voltages from the output of the drive or from any external option unit.

The drive must be installed in accordance with the instructions given in this guide. Failure to observe the instructions could result in a fire hazard.

1.6 Stored electrical charge

The drive contains capacitors that remain charged to a potentially lethal voltage after the AC supply has been disconnected. If the drive has been energized, the AC supply must be isolated at least ten minutes before work may continue.

1.7 Mechanical hazards

Careful consideration must be given to the functions of the drive or controller which might result in a hazard, either through their intended behaviour or through incorrect operation due to a fault. In any application where a malfunction of the drive or its control system could lead to or allow damage, loss or injury, a risk analysis must be carried out, and where necessary, further measures taken to reduce the risk - for example, an overspeed protection device in case of failure of the speed control, or a fail-safe mechanical brake in case of loss of motor braking.

With the sole exception of the Safe Torque Off function, none of the drive functions must be used to ensure safety of personnel, i.e. they must not be used for safety-related functions.

The Safe Torque Off function may be used in a safety-related application. The system designer is responsible for ensuring that the complete system is safe and designed correctly according to the relevant safety standards.

The design of safety-related control systems must only be done by personnel with the required training and experience. The Safe Torque Off function will only ensure the safety of a machine if it is correctly incorporated into a complete safety system. The system must be subject to a risk assessment to confirm that the residual risk of an unsafe event is at an acceptable level for the application.

1.11 Motor

The safety of the motor under variable speed conditions must be ensured.

To avoid the risk of physical injury, do not exceed the maximum specified speed of the motor.

Low speeds may cause the motor to overheat because the cooling fan becomes less effective, causing a fire hazard. The motor should be installed with a protection thermistor. If necessary, an electric forced vent fan should be used.

The values of the motor parameters set in the drive affect the protection of the motor. The default values in the drive must not be relied upon. It is essential that the correct value is entered in the Motor Rated Current parameter.

1.12 Mechanical brake control

Any brake control functions are provided to allow well co-ordinated operation of an external brake with the drive. While both hardware and software are designed to high standards of quality and robustness, they are not intended for use as safety functions, i.e. where a fault or failure would result in a risk of injury. In any application where the incorrect operation of the brake release mechanism could result in injury, independent protection devices of proven integrity must also be incorporated.

1.13 Adjusting parameters

Some parameters have a profound effect on the operation of the drive. They must not be altered without careful consideration of the impact on the controlled system. Measures must be taken to prevent unwanted changes due to error or tampering.

1.14 Electromagnetic compatibility (EMC)

Installation instructions for a range of EMC environments are provided in the relevant Power Installation Guide. If the installation is poorly designed or other equipment does not comply with suitable standards for EMC, the product might cause or suffer from disturbance due to electromagnetic interaction with other equipment. It is the responsibility of the installer to ensure that the equipment or system into which the product is incorporated complies with the relevant EMC legislation in the place of use.

2 Introduction

2.1 General

The SI-Interbus option module allows a Control Techniques drive to be connected to an Interbus network and operate as an Interbus slave device. It will allow transfer of up to 10 x 16-bit cyclic input data and 10 x 16-bit cyclic output data between the local drive (and its option modules), and external devices on the Interbus network.

The SI-Interbus module can be fitted to any one of the expansion slots in the Unidrive M200 to M400, Unidrive M600/M7XX, Digitax HD or Commander C200/C300.

2.2 Identification

The SI-Interbus option module can be identified by:

• The label located on the top of the option module (Table 2-1 SI-Interbus top label (500 kBd and 2 MBd))

• The colour of the front bezel (Grey)

Figure 2-1 SI-Interbus option module (2 MBd)

Table 2-1 shows sample module labels that would be fitted to the SI-Interbus modules

2.3 Date code format

The module date code is a four digit number. The first two digits indicate the year and the remaining two digits indicate the week of the year in which the option module was manufactured.

Example:

A date code of 1914 would correspond to week 14 of the year 2019.

This date code format (YYWW) is different to the module manufacture date code as displayed in the module parameter Pr MM.056 (YYMM).

2.4 Terminology

2.4.1 Input / Output

Throughout this document, the terms IN (or Input) and OUT (or Output) when referring to the cyclic data, refer to the data in relation to the Interbus master, so IN (or Input) would refer to the data transmitted from the SI-Interbus to the Interbus master and OUT (or Output) would refer to the data transmitted from the Interbus master to the SI-Interbus module.

2.4.2 Parameter reference

The parameters within the SI-Interbus module use a 2-digit number reference for the menu number and a 3-digit number reference for the parameter number. However, some features (such as the cyclic mappings parameters) for compatibility reasons only support a 2-digit number reference for the parameter, any 2-digit parameter reference used in this document may also be used as a 3-digit number reference by adding a leading 0.

So, for example, in Figure 6-1 Network loss trip detection, the setup parameters

15.07, 16.07 and 17.07 are used, these may be read as 15.007, 16.007 and 17.007 respectively.

5.1 Interbus cable

Interbus cable has three twisted pairs plus overall shielding. The colours normally used on Interbus networks are shown in Table 5-1 SI-Interbus connections. It is recommended to follow these wiring guidelines as this will make it easier to trace possible wiring errors during commissioning.

5.2 SI-Interbus cable shield connections

The Remote Bus IN and Remote Bus OUT cable shields MUST be connected to the shell of the connector. There is no requirement to connect the cable shields directly to Ground at any other point in the Interbus network.

5.3 Interbus network termination

Termination resistors are not required on Interbus networks, as each section of cable is automatically terminated on every Interbus device. The Ground Tab of the SI-Interbus must be connected to a suitable grounding point as close to the drive as possible using the minimal cable length.

5.4 Maximum network length

The maximum cable length is 400 metres between Remote Bus devices. Hence, the maximum total length of the Interbus network depends entirely on the number of devices connected to the network.

6.1 Node address

Interbus devices do not require a specific node address to be configured, the physical wiring of the network determines the Communication Reference (CR) that will be assigned to the device by the Interbus master controller.

6.2 Communication data rate

Interbus networks operate at a fixed baud rate, either 500 kBd or 2 MBd. The SI-Interbus module is configured during manufacture to operate at one of these rates, this configuration is determined by the part number specified at the time of ordering and cannot be changed by the user.

6.3 Parameter reference

Parameters are referenced using the notation Pr MM.xx, where ‘Pr’ means parameter, ‘MM’ represents menu 15, 16 or 17 (depending upon which slot contains the option module) and ‘xx’ is the parameter number within the menu.

6.4 Configuring the cyclic data

6.4.1 What is cyclic data

Cyclic data is a method of data transfer that must be setup during network configuration, but is transmitted automatically once configuration is complete. The high speed data transfer is achieved by transmitting only data bytes over the Interbus network, and relying on local mapping information within the SI-Interbus and Interbus master controller to ensure that the correct data is sent to the correct locations. This method relies on the master controller program writing and reading data values to and from the registers allocated to the node during network configuration, and the source and destination of IN and OUT data being setup correctly in the drive.

20 SI-INTERBUS User Guide

Issue Number: 1

The flexibility of the SI-Interbus means that each cyclic data OUT channel can be

NOTE

directed to any read-write drive (or option module) parameter. Similarly, each cyclic data IN channel can use any drive (or option module) parameter as a source of data.

The cyclic data mapping cannot be changed dynamically, as changes to the mapping parameters will only take effect during initialisation of the SI-Interbus, i.e. after a reset, or at power up.

6.4.2 Data format

The default data format is 4 words IN and 4 words OUT, this value can be changed to suit the application (up to 10 IN and 10 OUT words). Each cyclic data channel is mapped directly to a drive (or option module) parameter.

The SI-Interbus can map a total of up to 10 words as input and 10 words as output, by default with Pr MM.034 (Data Compression Enable) = Off, each cyclic channel will map 2 words to the mapped parameter, irrespective of whether the parameter is a 16-bit or 32-bit parameter, this gives a total number of 5 available mappings. If any desired mapping parameter is less than 32 bits in size, then Pr MM.034 (Data Compression Enable) may be set to On, this will then use only 1 word for each cyclic mapping channel as long as the mapped parameter size is less than 32 bits. This increases the number of available mappings by 1 for each mapped parameter that is not a 32-bit parameter, up to a maximum of 10 parameters.

If the mapped parameter size is actually 32 bits, then 2 words will still be used to transfer the data.

6.4.6 Direct data mapping

By default, the cyclic data mapping parameters MM.010 to MM.029 are used as pointers to specify the destination parameters for OUT data received from the Interbus master controller, and the source parameter of IN data to be transmitted to the Interbus master controller.

When direct data mapping is enabled (Pr MM.009 = On), the cyclic data mapping parameters are used as the actual source or destination parameters for the cyclic data.

Hence, IN data values read from Pr MM.010 to MM.019 are transmitted to the Interbus master controller and OUT data values arriving from the Interbus master controller are written directly into Pr MM.020 to Pr MM.029.

6.4.8 Network loss trip timeout

The SI-Interbus resets an internal timer when a valid cyclic data message is received from the Interbus network. The network loss trip is triggered when no new messages are received before the timer times out. The SI-Interbus error code parameter (Pr MM.050) will show a value of 65 when a network loss trip has occurred.

Default 200 (ms)

Pr MM.007

The network loss trip is not enabled internally until cyclic data has been detected. This prevents spurious network loss trips while the Interbus master controller is initialising the network.

Figure 6-1 Network loss trip detection

Type 1 6- bi t

Access RW

Network Loss Trip Timeout

As the trip delay time is reduced, the network loss trip will occur more quickly in the event of a loss of network. However, if the network loss trip time is reduced too far, spurious network loss trips may occur due to the timeout occurring before the next message has arrived.

The minimum network loss trip time for a particular network depends entirely on the number of messages per second being received under normal operation. As a rough guide, the network loss trip time should be set such that a minimum of 4 messages will be received in the specified time period under normal operating conditions.

The network loss trip can be disabled by setting Pr MM.007 to 0. In this case, the drive will continue to operate using the last received values. It is the user’s responsibility to ensure that adequate safety precautions are taken to prevent damage or injury by disabling the drive in the event of a loss of communications.

6.4.9 Cyclic data mapping status

NOTE

If the SI-Interbus operating status parameter (Pr MM.006) indicates a value of -3, a mapping configuration error has been detected. The actual reason for the error is indicated by the mapping status parameter, Pr MM.049. When a mapping error has been corrected, reset the SI-Interbus by setting Pr MM.032 to On.

information

Safety

Introduction

Pr MM.049

Possible values for the mapping status are shown in Table 12-2 Mapping status codes.

If the mapping configuration size has changed (Pr MM.005 Interbus Data Format), then the module reset is insufficient to fully initialise the Interbus network and after saving parameters, the module must be power-cycled.

6.4.10 Block mapping

Block mapping provides a quick and convenient way of mapping sequential parameters to the Interbus network with the minimum number of mapping parameters specified.

Block mapping is used automatically if:

• The value entered in the mapping parameters (Pr MM.010 to MM.029) are specified

in ascending order (i.e. lowest value parameter number first).

• The menu number of adjacent mappings are identical.

Care must be taken to ensure the total number of cyclic mappings specified does not exceed the maximum number allowed (Pr MM.005).

For example, the following mappings would map 5 x 32-bit parameters in menu 20, starting from Pr 20.021 to Pr 20.025 inclusive as inputs and 5 x 16-bit parameters in menu 18, starting from Pr 18.011 to Pr 18.015 inclusive and 5 x 16-bit parameters in menu 19, starting at Pr 19.021 to Pr 19.025 inclusive as outputs.

6.4.11 Disabling cyclic data channels

If any cyclic data channels are not being used, the associated mapping parameters should be set to 0. The Interbus master controller will transmit a value of 0 for the unused cyclic data words, and any unused incoming data values will be set to 0 before being passed to the Interbus master controller.

8 Non-Cyclic data

NOTE

The non-cyclic data channel provides a method for the Interbus master controller to read from or write to any parameter within the drive or option module. This channel can be used for single infrequent data transfers, or uploading and downloading parameter sets to or from a particular node.

The SI-Interbus provides three non-cyclic data formats, plus the option to disable noncyclic data.

• CT Single Word format (mode 1, see section 8.1 Mode 1 - CT Single Word mode)

• PPO 4 Word format (mode 2, see section 8.2 Mode 2 - PPO 4 Word mode)

• Peripheral Communications Protocol V2.0 (mode 3, see section 8.3 Mode 3 -

Peripheral Communications Protocol V2.0)

The non-cyclic mode is indicated by the first digit in the value of Pr MM.005 (Interbus Data format) as shown in the following table.

CT Single Word non-cyclic (mode1).

Uses 2 cyclic data words if data compression is disabled or 1 cyclic data word if data compression is enabled (Pr MM.034).

Pr MM.010 and Pr MM.020 will be set to the value 6150 and any existing mappings will be moved down one place.

PPO 4 Word non-cyclic data (mode 2).

Uses four cyclic data words.

Pr MM.010 and Pr MM.020 will be set to the value 6151 and any existing mappings will be moved down one place.

Peripheral Communications Protocol (PCP) V2.0.

Existing mapping configuration will not be affected.

8.1 Mode 1 - CT Single Word mode

The CT Single Word (mode 1) uses one cyclic channel for non-cyclic data. The noncyclic sub-protocol requires a specific sequence of 4 (16-bit parameters) or 6 (32-bit parameters) telegrams to implement the parameter access. Each non-cyclic word or telegram is split into 2 bytes to implement the sub-protocol, with the high byte containing the control codes for each telegram, and the low byte containing the data for each telegram.

If cyclic data compression is disabled (Pr MM.034 = Off), the CT Single Word non-cyclic channel will be 32 bits wide, i.e. uses 2 words, and data must be transferred on the low word. If cyclic data compression is enabled (Pr MM.034 = On), the CT Single Word noncyclic channel will revert to 16 bits and only use 1 word.

8.1.1 Mapping for CT Single Word non-cyclic data

To configure an SI-Interbus in slot 3 for CT Single Word mode non-cyclic data, the following steps must be performed:

• Set Pr 17.005 to the required mode

• Set Pr 17.032 to On to reset and reconfigure the SI-Interbus

When the SI-Interbus re-initialises, it will map cyclic data IN word 0 and OUT word 0 to the CT Single Word protocol parameter, Pr 61.50. All existing mapping parameters will be moved down by 1 place, i.e. the previous mapping set in Pr 17.010 and Pr 17.020 will now appear in Pr 17.011 and Pr 17.021 respectively.

Table 8-2 Six cyclic words with CT Single Word non-cyclic data mapping shows what happens to the mappings when the data format is changed from 6 cyclic words to 6 cyclic words with CT Single Word non-cyclic data.

The problem with this setup is that the user defined mappings (Pr 17.012 and Pr 17.022) are lost when the SI-Interbus is re-initialised. This is because there is insufficient mappings available to move the user defined channel into.

To maintain all mappings when adding the CT Single Word non-cyclic data channel, the cyclic data format (Pr 17.005) needs to be set to 108, this adds an additional cyclic channel to accommodate the user defined channel as shown in Table 8-3 Eight cyclic words with CT Single Word non-cyclic data mapping.

8.1.2 CT Single Word protocol

The CT Single Word protocol uses the lower 16 bits of the non-cyclic channel if data compression is disabled, and all 16 bits if data compression is enabled.

All parameter values are written as signed 32-bit data values. Decimal point information is inserted automatically when the data value is written to the drive, and removed when the data value is read.

Hence, the number of decimal places of the target parameter must be known.

Writing a value of 1234 to a parameter with 2 decimal places will produce a value of

12.34 in the target parameter. Similarly, reading a value of 12.34 will return a 32-bit integer value of 1234.

The CT Single Word format is shown in Table 8-4 CT Single Word bit significance.

This shows which part of the message is currently in progress. Setting the stamp number to 0 resets the internal non-cyclic state machine.

Specifies whether a 16-bit or 32-bit data value is to be accessed. If 32-BIT is set to 1, telegrams 5 and 6 will be used to transfer the additional data bytes. If 32-BIT is set to 0, then the data bytes will be transferred in telegrams 3 and 4.

Indicates the success or failure of the message. Failure could occur if the parameter does not exist, or is read-only or write-only parameter. This bit will also be set if the parameter value is out of range in 16-bit mode.

Defines whether the data word is part of a READ or WRITE cycle.

8.1.3 16-bit parameter access

16-bit data can be accessed using only 4 telegrams. Telegram 4 becomes the low data byte request (or value, for a write sequence) and telegrams 5 and 6 are not required. If an attempt is made to access a 32-bit parameter, the parameter value will be returned, provided that the parameter value does not exceed the signed 16-bit limits (-32768 to 32767). If the value is not within the signed 16-bit value, the ERR bit will be set.

When writing data to a 32-bit parameter using 16-bit mode, the 16-bit data will be treated as a signed 16-bit data value. This limits the range that can be written to a 32-bit parameter.

8.1.4 Reading parameters using CT Single Word

To read 32-bit parameters using CT Single Word non-cyclic channel, the following “telegrams” must be transmitted to construct the final message.

• Telegram 1 Define menu number.

• Telegram 2 Define parameter number.

• Telegram 3 Request high data byte.

• Telegram 4 Request mid-high data byte (32-bit) or low data byte (16-bit).

• Telegram 5 Request mid-low data byte (32-bit).

• Telegram 6 Request low data byte (32-bit).

Figure 8-1 CT Single Word read sequence shows the normal sequence for reading a parameter using CT Single Word non-cyclic.

If a telegram produces an error at any point in the sequence the reply to the master will have the error bit ERR set to a 1 and the data bits will have no significance. Setting the stamp number to 0 will reset the internal non-cyclic state machine.

Pr 2.001 = (high byte * 2

= (0 * 16777216) + (1 * 65536) + (37 * 256) + 220 = 75228 = 7522.8 rpm

The internal state machine that controls the non-cyclic data transfer will only accept a new telegram if it contains the next expected telegram stamp number (i.e. after accepting telegram 2, the state machine will only respond to telegram 3. If any other telegram stamp number is received, it will be ignored).

If an error occurs in the Interbus master controller that causes the telegrams to get out of step, the master controller program should timeout, abort the message and reset the non-cyclic state machine. This is done by setting the non-cyclic word to 0.

8.1.8 Writing 16-bit parameters

Normally six telegrams would be required to access drive parameters using CT Single Word non-cyclic data. When accessing 16-bit data only four telegrams are required. If an attempt is made to read a 32-bit parameter from the drive, the parameter value will be returned provided that the parameter value does not exceed signed 16-bit limits. If the value is larger than a signed 16-bit value, the ERR bit will be set.

When writing data to a 32-bit parameter, the 16-bit data will be treated as a signed 16-bit data value. This limits the range that can be written to a 32-bit parameter.

8.2 Mode 2 - PPO 4 Word mode

PPO 4 word mode of non-cyclic data is a simple method of accessing non-cyclic data without the need for the telegrams required with Mode 1 non-cyclic data and its associated overheads. Mode 2 has the disadvantage of using four words of mappings and reduces the available free mappings accordingly.

8.2.1 Mapping for PPO 4 Word non-cyclic data

To configure an SI-Interbus in slot 3 for PPO 4 Word mode non-cyclic data, the following steps must be performed:

• Set Pr 17.005 to the required mode

• Set Pr 17.032 to On to reset and reconfigure the SI-Interbus

When the SI-Interbus re-initialises, it will map cyclic data IN words 0 to 3 and OUT words 0 to 3 to the PPO 4 Word protocol parameter, Pr 61.51. All existing mapping parameters will be moved down by one mapping, (i.e. the previous mappings set in Pr 17.010 and Pr 17.020 will now appear in Pr 17.011 and Pr 17.021 respectively).

Table 8-6 Six cyclic words with PPO 4 Word non-cyclic data mapping shows what happens to the mapping parameters when the data format is changed from 6 cyclic words (Pr 17.005=6) to 6 cyclic words with Mode 2 non-cyclic data. (Pr 17.005=206).

Reference

Pr 61.51, PPO 4 Word noncyclic mode 2

There are two problems with this setup, the first is that a configuration error will be raised because PPO 4 Word non-cyclic uses 4 words, so with the 6 words of cyclic data mapped, the number of mappings exceed the number specified (6). The second problem is that the user defined mappings (Pr 17.012 and Pr 17.022) are lost when the SI-Interbus is re-initialised. This is because there is insufficient mappings available to move the user defined channel into.

To maintain all mappings when adding the PPO 4 Word non-cyclic data channel, the cyclic data format (Pr 17.005) needs to be set to 210, this adds additional cyclic channels to accommodate the user defined channel as shown in Table 8-7 Ten cyclic words with PPO 4 Word non-cyclic data mapping.

8.2.2 PPO 4 Word protocol

The PPO 4 Word protocol uses the first four words (IN and OUT) of the non-cyclic channel.

Hence, the number of decimal places of the target parameter must be known.

Writing a value of 1234 to a parameter with 2 decimal places will produce a value of

12.34 in the target parameter. Similarly, reading a value of 12.34 will return a 32-bit integer value of 1234.

The PPO 4 Word protocol format is shown in Table 8-8 PPO 4 Word OUT data structure.

It is important that the correct module is selected from the XML file to ensure that the PPO 4 Word mode block is consistent otherwise data skew may occur. If the OUT data words 0 and 1 are left at the same value, the target parameter will be read or written to (depending on the TASK ID) on every data cycle. If the PPO 4 command is left in the data words, the read will be executed on every poll of the network, effectively providing a continuous read. Care should be taken to ensure the parameters for the read are setup before the TASK ID is changed from 0 to prevent incorrect data in the returned value.

8.3 Mode 3 - Peripheral Communications Protocol V2.0

The PCP non-cyclic mode is an object based protocol for implementing services that are more complex than unconfirmed cyclic data transfer. If selected, the PCP protocol supported by the SI-Interbus module uses the first word of the transmitted and received data. Unlike the non-cyclic modes 1 and 2, PCP mode is not represented in the mapping parameters (Pr MM.010 to MM.029) and can only be selected by the mode parameter (Pr MM.005) and not explicitly mapped.

When an Interbus network is initialised, each node supporting PCP is assigned a Communication Reference, or CR. Supported objects are shown in Table 8-19

PCP object specification and the supported services are shown in Table 8-20 PCP supported services.

8.3.3 Accessing drive parameters using the PCP objects

The supported objects permit the user to read or write to any parameter that supports that action, i.e. the user could not write to a read only parameter. Each object will represent a drive menu numbered from 0 to 200. The user will provide a sub-index within either the READ or WRITE service to access a specific parameter.

The objects will represent the Menus as follows: Object = Menu + 0x5000

The sub-index will equate to the required parameter number within the specified menu.

The only exception to this is parameter zero, (Pr MM.000) this can be accessed using the virtual parameter Pr 61.001. A sub-index value of zero will return an error (see Table 8-23 Control Techniques defined service error codes).

8.3.3.1 READ object

Index: 0x5000 + Menu Sub-index: Parameter

The READ object is used to read a value from a parameter within the drive. No additional data bytes are required. If the read is successful, a success response will be returned, with four data bytes containing the value of the target parameter.

10 SI-Applications parameters

The SI-Interbus will redirect any menu accesses, for menus 70 to 91, to the SI-Applications (or MCi2x0) module in the lowest numbered slot. This is convenient to use if there is only the one SI-Applications (or MCi2x0) module fitted to the drive, as it guarantees that data will always be written to or read from the module even if it was moved to a different slot position.

If more than one SI-Applications (or MCi2x0) option module is fitted then, to ensure the correct module is accessed, it will be necessary to access the module in a specific slot directly, this is achieved by using the slot specific menus 100 to 121, 130 to 151 and 160 to 181 for menus 70 to 91 in slots 1 to 3 respectively.

Note that only the PLC registers (menus 70 to 79) are available in the MCi2x0 module.

If a parameter read request comes over Interbus to read Pr 71.08, this will be redirected to the SI-Applications in the lowest slot number, i.e. the SI-Applications in slot 3. The value in _Q08% from slot 3 will be returned.

If a parameter read request comes over Interbus to read Pr 161.08, this will be sent straight to the SI-Applications in slot 3. The value in _Q08% from slot 3 will be returned.

If a parameter read request comes over Interbus to read Pr 101.08, this will be sent straight to slot 1. As there is no module fitted in slot 1, an error message will be returned, indicating that the parameter does not exist.

11 Control / status word

The control and status words allow the digital control and monitoring of the drive to be implemented using a single data word for each function. Each bit in the control word has a particular function and provides a method of controlling the output functions of the drive, such as run and direction.

Each bit in the status word provides feedback about the drive’s state of health and operational condition, such as drive ok, drive at speed, etc.

The default cyclic data mappings of the SI-Interbus module use the drive control word (Pr 06.042) and preset reference 1 (Pr 01.021) for the OUT data, and the drive status word (Pr 10.040) and post ramp reference (Pr 02.001) for the IN data.

If the drive control word is to be used for controlling the drive over the Interbus network, then the control word must be enabled (Pr 06.043 = On).

11.1 Control word

The control word consists of sixteen control bits, some of which are reserved.

Table 11-1 Control word bit functions shows the functions of each bit in the control word, and Table 11-2 Control word bit definitions shows the functions of each control bit in more detail. For further details about the drive control word and sequencing bits please refer to the appropriate drive documentation.

ENABLE

To enable fieldbus control, the Control Word Enable (Pr 06.043) must be set to ‘On’, the source of the control signals (RUN, FWD/REV. JOG, etc.) is selected using the AUTO bit (b7). When the AUTO bit (b7) is set to ‘1’, the control word is used as the source for the drive control. When the AUTO bit (b7) is set to 0, the drive will revert to terminal control.

For safety reasons, the external SAFE TORQUE OFF signal must be present before the fieldbus control word can be used to start the drive. This signal is normally provided by an external “Emergency Stop” circuit to ensure that the drive is disabled in an emergency situation.

The control word REMOTE bit (b8) directly controls the drive parameter Pr 01.042, the function of which is to select the digital speed reference as the source of the drive’s speed reference. When the REMOTE bit (b8) is set to 1 the fieldbus speed reference will be used. When the REMOTE bit (b8) is set to 0 the drive will revert to using the external analog speed reference.

62 SI-INTERBUS User Guide

Issue Number: 1

The default digital speed reference selected when REMOTE is set to 1 will be Pr 01.021, however Pr 01.015 can be used to change which of the digital references is selected. For further details on the drive digital speed reference, please refer to the appropriate drive documentation.

Set to 1 to enable the drive. Resetting to 0 will immediately disable the drive, and the motor will coast to a stop. The external SAFE TORQUE OFF signal must also be present before the drive can be enabled.

Set to 1 (with ENABLE set to 1) to run the motor in the forward direction. When reset to 0, the drive will decelerate the motor to a controlled stop.

Set to 1 to jog the motor forward. This signal needs to be used in conjunction with the ENABLE bit. This signal is overridden by a RUN, RUN REV or RUN FWD signal

Set to 1 (with ENABLE set to 1) to run the motor in the reverse direction. When reset to 0, the drive will decelerate the motor to a controlled stop

Set to 1 to select the reverse direction. Set to 0 to run in the forward direction. The RUN signal is used to start and stop the motor.

Set to 1 to run the motor. FWD/REV is used to select the direction of motor rotation. When reset to 0, the drive will decelerate the motor to a controlled stop.

Set to 1 to allow the sequencing bit to be latched. If NOT STOP is zero, all latches are cleared and held at 0.

Set to 1 to enable fieldbus control of the drive Control Word. The Control Word Enable (Pr 06.043) must also be set to 1. When set to 0, the drive will operate under terminal control.

Set to 1 to select digital speed reference 1 (Pr 01.021), and set to 0 to select analog reference 1 (Pr 01.036). REMOTE directly controls Pr 01.042, so reference selector (Pr 01.014) and preset selector (Pr 01.015) must both be set to 0 (default) for the REMOTE bit to work properly.

Set to 1 to jog the motor in reverse. This signal needs to be used in conjunction with the ENABLE bit. This signal is overridden by a RUN, RUN REV or RUN FWD command.

Set to 1 to trip the drive at any time. The trip display on the drive will be ‘Control Word’ and the trip code will be 35. AUTO (b7) has no effect on this function. The trip cannot be cleared until TRIP is reset to 0.

A 0 to 1 transition of the RESET bit will reset the drive from a trip condition. If the reason for the trip is still present, or another fault has been detected, the drive will immediately trip again. When resetting the drive, it is recommended to check the status word to ensure that the reset was successful, before attempting to re-start the drive.

This watchdog is provided for an external keypad or other devices where a break in the communication link must be detected. The watchdog system can be enabled and/or serviced if this bit is changed from zero to one while the control word is enabled. Once the watchdog is enabled it must be serviced at least once every second or a ‘Watchdog’ trip will occur (trip code 30). The watchdog is disabled when a ‘Watchdog’ trip occurs, and so it must be re-enabled when the trip is reset.

By default, parameters MM.010 to MM.029 are used as pointers to specify the destination parameter for OUT data received from the Interbus master controller, and the source parameter of IN data to be transmitted to the Interbus master controller.

When direct data mapping is enabled, Pr MM.010 to Pr MM.019 are used as the source parameters for IN data and Pr MM.020 to Pr MM.029 are used as the destination parameters for OUT data.

Hence, IN data values read from Pr MM.010 to MM.019 will be transmitted to the Interbus master controller and OUT data values arriving from the Interbus master controller will be written directly into Pr MM.020 to Pr MM.029.

15.1 Interbus CMD tool

The CMD tool is a Windows© (not later than Windows XP) based software package developed by Phoenix Contact and used to configure and diagnose the Generation 4 Interbus master controllers. An external database file, drive icon image files and a text file (README_CT.TXT) with instructions on how to install the drive support files to the appropriate directories, and import them into the CMD configuration tool, are available from Control Techniques for use with the CMD tool application. These files are provided in a compressed file (CT_IBS.ZIP) available from your local Control Techniques Drive Centre.

The Interbus CMD tool support files are not essential when configuring an Interbus network, each node can be entered manually, or the master controller can scan the network to determine which nodes are connected.

information

Safety

Address: This is the unique network identification given to a networked device to allow communication on a network. When a device sends or receives data the address is used to determine the source and the destination of the message.

Bit: A binary digit, this may have the value of 1 or 0.

Block mapping: A method of mapping a range of consecutive parameters using only

two ascending parameters. This means that by using two mapping parameters, up to 10 consecutive mappings may be made.

Byte: A collection of 8 binary digits that collectively store a value. This may be signed or unsigned.

Compression: By default SI-INTERBUS transmits values as 32-bits on the network. It is possible by using compression to reduce the number of bits transmitted when sending 16-bit (or smaller) values on the network to 16-bit (32-bit values will still be transmitted as 32-bit values). This has the advantage of reducing the volume of traffic on the network and allowing more parameters to be mapped within SI-INTERBUS.

Control word: A collection of binary digits that are used to control the drive. Features typically include directional controls, run controls and other similar functions.

Cyclic data: This consists of values that are sent at regular or cyclic intervals across the network. A typical use of cyclic data would be the transmission of a speed reference or a control word.

Data format: Determines the quantity and function of the data sent and received across the network.

Data rate: Determines the communication speed of the network, the higher the value the more data can be sent across the network in the same time period.

Device: A piece of equipment connected to a network, this may be any type of equipment including repeaters, hubs, masters or slaves.

Direct data mapping: Data is sent directly to the mapping parameters in the drive rather than the parameters redirecting the data to another parameter.

Mode 2 - PPO4 word mode: A method of sending 4 non-cyclic data words using cyclic

channels.

Network loss trip: A method to determine when a node has lost communication with the master.

Module ID code: Indicates the type of solutions module that is fitted in the corresponding slot.

Node: A device on the network. This may be either a device such as a drive or part of the network such as a repeater.

Non-cyclic data: Data that is requested or sent by the master as required. This is not sent on a regular basis and generally allows access to any parameter. This is useful for occasional changes or configuration purposes.

Response ID: The response code of the message received when using PPO4 word non-cyclic communication.

Slave: A device on the INTERBUS network such as a drive or sensor. A slave device will only respond to messages from a master.

Status word: A value that denotes the status of the drive. Each bit within the word will have a specific meaning.

Tel egram: A message used within mode 1 non-cyclic data communication. This term is sometimes used to represent a generic message on the network.

Termination: This is used at both ends of a network segment to prevent reflections and reduce noise.

Watchdog: A method used to determine if a communication system is healthy. A typical watchdog scheme uses a handshaking system to check both the master and slave are participating in communications.
