The adapter features include:

• Typical mounting in a PowerFlex 7-Class drive using captive screws to

secure and ground the adapter to the drive.

• Compatibility with various configuration tools to configure the adapter

and connected drive. The tools include the PowerFlex HIM on the drive, and drive-configuration software such as DriveExplorer (version 2.01 or higher) or DriveExecutive (version 3.01 or higher).

• Status indicators that report the status of the drive communications, the

adapter, and network. They are visible when the drive cover is open or closed.

• Parameter-configurable I/O (Logic Command/Reference and up to four

pairs of Datalinks) to meet application requirements.

• User-defined fault actions to determine how the adapter and PowerFlex

drive respond to communication disruptions on the network.

• Switches to allow setting a node address before applying power to the

drive. Alternatively, you can disable the switches and use a parameter to configure the node address.

• A switch lets you select from the following three network protocols:

– Modbus™ RTU – Metasys™ N2 – Siemens Building Technologies P1 FLN™

Compatible Products

• Available read/write access to parameters, allowing parameter values to

be configured and monitored over the network.

Required Equipment

Equipment Shipped with the Adapter

When you unpack the adapter, verify that the package includes:

❑ One adapter ❑ A 2.54 cm (1 in.) and a 15.24 cm (6 in.) Internal Interface cable (only

one cable is needed to connect the adapter to the drive)

User-Supplied Equipment

To install and configure the adapter, you must supply:

❑ A small flathead screwdriver ❑ Network-specific cable to connect the adapter to the network. Refer to

the network-specific documentation for the cable recommendations and requirements.

❑ Configuration tool, such as:

– PowerFlex 7-Class HIM (20-HIM-*) – DriveExplorer (version 2.01 or higher) – DriveExecutive stand-alone software (version 3.01 or higher) or

bundled with the DriveTools SP suite (version 1.01 or higher)

– Third-party network configuration software

❑ A PC connection to the network

Safety Precautions

Please read the following safety precautions carefully.

ATTENTION: Risk of injury or death exists. The PowerFlex drive may contain high voltages that can cause injury or death.

Remove all power from the PowerFlex drive, and then verify power has been discharged before installing or removing an adapter.

ATTENTION: Risk of injury or equipment damage exists. Only personnel familiar with drive and power products and the

associated machinery should plan or implement the installation, start up, configuration, and subsequent maintenance of the product using an adapter. Read and understand this entire manual before proceeding. Failure to comply may result in injury and/or equipment damage.

ATTENTION: Risk of equipment damage exists. The adapter contains ESD (Electrostatic Discharge) sensitive parts that can be

damaged if you do not follow ESD control procedures. Static control precautions are required when handling the adapter. If you are unfamiliar with static control procedures, refer to Guarding Against Electrostatic Damage (publication 8000-4.5.2).

ATTENTION: Risk of injury or equipment damage exists. If the adapter is transmitting control I/O to the drive, the drive may fault

when you reset the adapter. Determine how your drive will respond before resetting an adapter.

20-COMM-H RS-485 HVAC Adapter User Manual

Publication 20COMM-UM009D-EN-P

1-4 Getting Started

ATTENTION: Risk of injury or equipment damage exists. Parameter 15 - [Comm Flt Action] lets you determine the

action of the adapter and connected drive if communications are disrupted. By default, this parameter faults the drive. You can set this parameter so that the drive continues to run. Precautions should be taken to ensure that the setting of this parameter does not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable).

ATTENTION: Risk of injury or equipment damage exists. Parameter 11 - [Network Timeout] lets you determine how

long it will take the adapter to detect network communication losses. By default, this parameter sets the timeout to ten seconds. It can be set so that the duration is shorter, longer, or disabled. Take precautions to ensure that the setting does not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable).

ATTENTION: Risk of injury or equipment damage exists. DPI or SCANport host products must not be directly connected via

1202 cables. Unpredictable behavior due to timing and other internal procedures can result if two or more hosts are connected in this manner.

ATTENTION: Risk of injury or equipment damage exists. When a system is configured for the first time, there may be

unintended or incorrect machine motion. Disconnect the motor from the machine or process during initial system testing.

ATTENTION: Risk of injury or equipment damage exists. The examples in this publication are intended solely for purposes of

example. There are many variables and requirements with any application. Rockwell Automation, Inc. does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

3-6 Configuring the Adapter

Setting a Network Time-out

The network timeout sets an interval within which the adapter must communicate with its master. If this time is exceeded, the adapter determines a loss of network communications has occurred and responds with the action specified in Parameter 15 - [Comm Flt Action].

By default, the timeout is set to ten (10) seconds. You can increase or decrease this value. Alternatively, you can set the value to zero (0) so that the adapter does not detect communication losses.

ATTENTION: Risk of injury or equipment damage exists. Parameter 11 - [Network Timeout] lets you determine how

long it will take your adapter to detect network communication losses. By default, this parameter sets the timeout to ten (10) seconds. You can set it so that the duration is shorter, longer, or disabled. Take precautions to ensure that the setting does not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable).

Set the network timeout in Parameter 11 - [Network Timeout].

Configuring the Adapter 3-7

Setting a Fault Action

By default, when I/O communications are disrupted (for example, a cable is disconnected), the drive responds by faulting if it is using I/O from the network. You can configure a different response to disrupted I/O communication using Parameter 15 - [Comm Flt Action].

ATTENTION: Risk of injury or equipment damage exists. Parameter 15 - [Comm Flt Action] lets you determine the action

of the adapter and connected drive if I/O communications are disrupted. By default, this parameter faults the drive. You can set this parameter so that the drive continues to run. Precautions should be taken to ensure that the setting of this parameter does not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable).

Changing the Fault Action

Set the value of Parameter 15 - [Comm Flt Action] to the desired response:

Value Action Description

0 Fault The drive is faulted and stopped. (Default) 1 Stop The drive is stopped, but not faulted. 2 Zero Data The drive is sent 0 for output data. (The command word and Reference are

set to zero.) This does not command a stop. 3 Hold Last The drive continues in its present state. 4 Send Flt Cfg The drive is sent the data that you set in the fault configuration parameters

(Parameters 18 - [Flt Cfg Logic] through 27 - [Flt Cfg D2 In]).

Understanding Modbus RTU

The Modbus RTU protocol is a messaging structure used to establish master-slave communication between intelligent devices. The protocol defines the format of the messages.

Messages from a master to a slave contain the address of the slave, a function code defining the requested action, any data to be sent, and an error-checking field. Messages from a slave to a master contain fields confirming the action taken, any data to be returned, and an error-checking field. If an error occurred in the receipt of the message or if the slave is unable to perform the requested action, the slave will construct an error message and send it as its response.

Modbus RTU can access a single address or multiple addresses simultaneously, either reading or writing single-bit values or 16-bit values.

Modbus RTU Data Formats

Modbus data types are 1-bit and 16-bit values. Refer to Table 4.A.

All data addresses in Modbus messages are referenced to zero. That is, the first occurrence of a data item is addressed as item number zero. Therefore, when you create a message, you must address it to one less than the Modbus address in the manual. The following are examples:

Adapter Modbus Register Map

• Logic Command is Holding Register address 4x0001 in Table 4.F on

page 4-7, so you address it as register “0000” in the data address field of

the message.

• Feedback Hi is Input Register address 3x0003 in Table 4.H on page 4-8

so you address it as register “0002” in the data address field of the message.

• Start is Coil address 0x0002 in Table 4.E on page 4-6

as coil “0001” in the data address field of the message.

• At Speed is Input address 1x0009 in Table 4.G on page 4-7

20-COMM-H RS-485 HVAC Adapter User Manual

Publication 20COMM-UM009D-EN-P

On Modbus, data transfers are used to transfer the I/O data that controls the drive and sets its Reference. Note that output I/O is data that the master device sends and the adapter receives. Input I/O is status data that the adapter sends and the master device receives.

Important:In order for the drive to use the I/O and Reference from the

Modbus RTU network, you must set parameters in it and the adapter to receive the I/O and Reference. For details, refer to

Setting the I/O Configuration

on page 3-5.

Using Modbus RTU 4-5

Setting the Logic Command and Reference

ATTENTION: Select and use either the “Product Logic Command Discrete Outputs (0x000x)” or the “Product Logic

Command Register Output (4x0001)” as a control method, but not both. Conflicts caused from using both methods can result in dangerous operation. Failure to observe this caution could cause bodily injury and/or damage to equipment.

On Modbus RTU, there are two ways to set the logic command: discrete outputs (Table 4.E on page 4-6

page 4-7).

• When you need to set only one bit in the logic command word, you can

use a discrete output. For example, to stop a PowerFlex 70/700 drive (bit

0), you can use a discrete output (Modbus Address 0x0001).

• When you need to set multi-bit fields in the logic status word or to set the

entire logic status word, you must use the register output to maintain data integrity. For example, to set the direction of a PowerFlex 70/700 drive (bits 4 and 5), you must use a register output (Modbus Address 4x0001).

) and register outputs (Table 4.F on

A 16-bit product logic word is buffered in the adapter, holding the last logic command sent to the drive regardless of whether it was sent through the discrete outputs or through the product logic command register output. When a bit is updated through the discrete outputs or the register output, a new logic command is generated and sent to the drive.

To set the Reference, you must use a register output (Modbus Address 4x0002 and/or 4x0003 in Table 4.F on page 4-7 is a scaled value; it is not an engineering value. For example, in PowerFlex 70/ 700 drives, the reference is scaled based on the value of Parameter 55 - [Maximum Freq], but the commanded maximum speed can never exceed the value of Parameter 82 - [Maximum Speed]. Tabl e 4.D References and their results on a PowerFlex 70/700 drive that has its

Parameters 55 - [Maximum Freq] set to 130 Hz and 82 - [Maximum Speed] set to 60 Hz.

(1)

A value of 32767 is equivalent to 100%. The effects of values greater than 32767 depend on whether the DPI product uses a bipolar or unipolar direction mode. Refer to the documentation for your DPI product.

(2)

The drive runs at 60 Hz instead of 130 Hz or 65 Hz because Parameter 82 - [Maximum Speed] sets 60 Hz as the maximum speed.

(3)

The Feedback value is also scaled based on the value of Parameter 55 - [Maximum Freq], For example, 60/130 = 0.46 so 32767 x 0.46 = 15123.

Accessing Drive Parameters

There are two methods for accessing drive parameters: the direct access method and the pointer access method.

Direct Access Method

You can use Function Code 03 to read and Function Codes 06 (single) and 16 (multiple) to write, to directly access the drive parameters (see

Table 4.B on page 4-2

read or write as opposed to first having to write the “Param# for INx” or “Param# for OUTx” using the Pointer Access Method.

When a 41000 or higher Modbus address is used, the adapter assumes the controller is accessing the drive’s parameters directly. The address is determined by:

16-bit Adapter Mode: Modbus Address = 41000 + (Drive Parameter #) 32-bit Adapter Mode: Modbus Address = 41000 + (Drive Parameter # x 2)

For example, with the adapter in 16-bit mode, Parameter 1 is accessed by Modbus Address 41000. In the 32-bit mode, Parameter 1 is accessed by Modbus Address 41002. Any attempts to access a parameter number that does not exist will return an error.

). This allows direct access of parameters in a single

The 32-bit adapter mode requires a minimum of two registers to read or write, and is always an even number since two 16-bit registers are read for each 32-bit data item.

Pointer Access Method

Reading Parameter Values

With a configurable input point, you can read any 16-bit parameter in the drive. The sequence for reading parameter values is as follows:

1. Set one or more Param# for INx points in the controller to the parameter

number(s) that you want to read. You can set up to eight Param# for INx points. Refer to Table 4.I on page 4-10

2. Send a message with a Write Single Register (code 06) or Write

Multiple Register (code 16) function. You need to send the Param# for INx point(s) to the adapter only one time per power cycle because, when the adapter receives the Param# for INx point(s), it stores them in its RAM. The adapter then continuously reads the values for the drive parameters specified in the Param# for INx points.

3. Send a message with a Read Input Registers (code 04) function. The

adapter reads the drive parameter(s) that have been configured in the Param# for IN point(s) and returns their values in the User INx point(s). It can return up to eight User INx points. Refer to Table 4.I on

page 4-10. You can perform Read Input Registers continuously, if

desired.

store the returned 16-bit data. Use both 16-bit data items to make one 32-bit value for drive parameter 12.

Writing Parameter Values

ATTENTION: Risk of equipment damage exists. If configurable output points are programmed to write parameter

data to Non-Volatile Storage (NVS) frequently, the NVS will quickly exceed its life cycle and cause the drive to malfunction. Do not create a program that frequently uses configurable outputs to write parameter data to NVS. Datalinks do not write to NVS and should be used for frequently changed parameters.

With a configurable output point, you can write a new value for any 16-bit parameter in the drive. The sequence for writing parameter values is as follows:

1. Set one or more Param# for OUTx points in the controller to the

parameter number(s) to which you want to write. A value of zero in the Param# field disables the writing of data for that specific point. Refer to the drive user manual for the desired parameter number(s). You can set up to three Param# for OUTx points at a time. Refer to Table 4.K on

page 4-12.

2. Send a message with a Write Single Register (code 06) or Write

Multiple Register (code 16) function. You need to send the Param# for OUTx point(s) to the adapter only one time per power cycle because, when the adapter receives the Param# for OUTx point(s), it stores them in its RAM.

3. Set the values that you want to write to the parameters in the User

OUTx points. You can set up to three User OUTx points at a time. Refer to Table 4.K on page 4-12

4. Send a message with a Write Single Register (code 06) or Write

16-bit Mode Example: Write a value of “101” to register 4x0015. Write a value of “123” to register 4x0012. The drive parameter 101 value now equals 12.3.

32-bit Mode: User OUT items are not supported when using the adapter in the 32-bit mode.

A Modbus RTU global broadcast feature enables you to send a command (start, stop, etc.) to all drives on the network at the same time by using Modbus Address “0.” This feature can also be used to write the same message to each network drive via a single message, for example setting Accel Time to 5 seconds in every drive.

Important:Every node capable of receiving a broadcast message will act

upon the message, so it is required that broadcast messages are used only on networks of similar devices. For example, PowerFlex 70 and 700 drives use the same Logic Command structure, Reference format and the same Modbus addressing, so these could be controlled together using a broadcast message. Always check the Modbus addressing, Logic Command structure, Reference format, etc. for every node device type before designing a system with broadcast messages.

The adapter also enables you to independently scale the broadcast message Reference of its connected drive by using Parameter 31 - [RTU Ref. Adjust]. The scaling factor can be set from 0…200.0%. This lets the drive Reference either match the broadcast message Reference (= 100%), scale below the broadcast message Reference (<100%), or scale above the broadcast message Reference (>100%).

Understanding Metasys N2

Metasys nodes are built up by the use of several virtual objects. The Metasys N2 master performs read and write commands to these virtual objects, and the adapter transfers/translates the data between these virtual objects and the drive.

When a read or write command occurs to a certain dedicated virtual object, data in the virtual objects is refreshed from or transferred to the drive.

The Metasys N2 master performs read and write commands to the virtual objects one at a time. The data types that are used in the virtual objects are binary input (BI), binary output (BO), analog input (AI), analog output (AO), and internal integer (ADI), which is a 16-bit data value.

The Metasys master also performs cyclic polling of all the virtual objects.

Device Identity

The 20-COMM-H adapter must be configured in the master controller as a Vendor device (VND) Code 10 hex.

Metasys N2 Virtual Objects

A Metasys N2 node may contain up to 256 virtual objects in each of its seven different data types, called regions (Table 5.A

Using Metasys N2 5-3

Using the Metasys N2 Point Map for I/O

On Metasys N2, data transfers are used to transfer the I/O data that controls the drive and sets its Reference. Note that Output I/O is data that the master device sends and the adapter receives. Input I/O is status data that the adapter sends and the master device receives.

Important:In order for the drive to use the I/O and Reference from the

Metasys N2 network, you must set parameters in it and the adapter to receive the I/O and Reference. For details, refer to

Setting the I/O Configuration

Setting the Logic Command and Reference

ATTENTION: Select and use either the point type Digital (BO) or the word type Analog (AO) as a control method, but not both.

Conflicts caused from using both methods can result in dangerous operation. Failure to observe this precaution could cause bodily injury and/or damage to equipment.

On Metasys N2, there are two ways to set the logic command: binary outputs (Table 5.L on page 5-5

page 5-6).

) and an analog output (Table 5.M on

on page 3-5.

• When you need to set only one bit in the Logic Command word, you can

use binary outputs. For example, to stop a PowerFlex 70/700 drive (bit

0), you can use a binary output (BO#1).

• When you need to set multi-bit fields in the Logic Command word or to

set the entire Logic Command word, you must use the analog output to maintain data integrity. For example, to set the Reference Selection of a PowerFlex 70/700 drive (bits 12…14), you must use an analog output (AO#1).

A 16-bit product logic word is buffered in the adapter, holding the last Logic Command sent to the drive regardless of whether it was sent through the binary outputs or through product logic command outputs (AO#1). When a bit is updated through either of these outputs, a new Logic Command will be generated and sent to the drive.

To set the Reference, you must use an analog output (AO#2). Table 5.G shows example References and their results on a PowerFlex 70/700 drive that has its Parameters 55 - [Maximum Freq] set to 70 Hz and 82 -

[Maximum Speed] set to 60 Hz, and adapter Parameter 29 - [N2 Ref Scale] is set to 32,767.

The actual value transmitted over the network is an engineering unit where 100% equals sending the value in the adapter Parameter 29 - [N2 Ref Scale], and 0% equals sending a zero.

The Feedback percent value is also scaled based on the value of adapter Parameter 29 - [N2 Ref Scale].

The drive runs at 60 Hz instead of 70 Hz because Parameter 82 - [Maximum Speed] sets 60 Hz as the maximum speed.

Pr. 29 Value

By default, Parameter 29 - [N2 Ref Scale] equals 32,767, which is the maximum Reference value for PowerFlex 70/700 drives. Note that additional scaling is performed in the PowerFlex 70/700 drive, where 32,767 equals the frequency selected in drive Parameter 55 - [Maximum Freq]. For other DPI hosts, refer to the documentation of the specific DPI host product.

Viewing the Logic Status and Feedback

On Metasys N2, there are two ways to view the Logic Status: binary inputs (Table 5.N on page 5-7 can use binary inputs when you need to view only one bit in the Logic Status word. For example, to view whether a PowerFlex 70/700 drive is ready (bit 0), you can use a binary input (BI 1).

When you need to view multi-bit fields in the Logic Status word, to view the entire Logic Status word, or to view the Feedback word, you must use an analog input. For example, to view the local control of a PowerFlex 70/ 700 drive (bits 9…11), you must use an analog input (AI #1). To view the Feedback, you must use an analog input (AI #2 or AI #3).

Configurable objects are inputs and outputs that let you read and write parameter values. These objects handle only 16-bit parameter values.

Reading Parameter Values

The configurable points may show any 16-bit parameter in the drive by configuring the Param# point. The Param# for INx points are stored in the RAM in the adapter and need to be written to only one time per power cycle.

The adapter reads the value of the drive parameter configured in the Param# point and shows the result in the User INx point. The adapter reads the parameter values from the drive continuously one at a time when Param# is set to a non-zero value. See Figure 5.1

ATTENTION: Risk of equipment damage exists. If configurable outputs are programmed to write parameter data to Non-Volatile Storage (NVS) frequently, the NVS will quickly exceed its life cycle and cause the drive to malfunction. Do not create a program that frequently uses configurable outputs to write parameter data to NVS. Datalinks do not write to NVS and should be used for frequently changed parameters.

TIP: Analog Data Integers (ADIs) are configured by first selecting an Analog Output (AO) setpoint and then selecting the ADI.

A value of zero in the Param# field disables the writing of data for that specific point. Refer to the drive user manual for the desired parameter number.

Understanding Siemens Building Technologies P1 FLN

ATTENTION: Risk of injury or equipment damage exists. On P1 FLN networks, 16-bit values are truncated to 15-bit values.

Unpredictable operation may result from using non-15-bit drive parameters with the configurable points. Recognize the data range limitation of P1 FLN and understand the data value ranges of each parameter to be accessed over the network. Refer to the drive user manual for information about drive parameter sizes.

P1 FLN nodes are built by the use of several points. The P1 FLN master controller performs read and write commands to these points, and the adapter transfers/translates the data between these points and the drive.

All values (byte-sized, Boolean, and true integers) are represented in a 16-bit word over the network, where the sign bit is always positive. The actual range allowed by P1 FLN, however, is always 15 bits: 0…32767 for integers, 0…255 for bytes, and 0 or 1 for Boolean. The limit of 15 bits prevents the use of the adapter’s P1 FLN mode with 32-bit DPI hosts, where either Reference/Feedback or Datalink values are represented in 32-bit format. 16-bit real values will be truncated to show only 15-bit values.

• The subpoint can be overridden by the operator.

• Unbundling a point allows the operator to set up a virtual point in the

Using Siemens Building Technologies P1 FLN 6-5

Using the P1 FLN Point Map for I/O

On Siemens Building Technologies P1 FLN, data transfers are used to transfer the I/O data that controls the drive and sets its Reference. Note that

Output I/O is data that the master device sends and the adapter receives. Input I/O is status data that the adapter sends and the master device receives.

Important:In order for the drive to use the I/O and Reference from the P1

FLN network, you must set parameters in it and the adapter to receive the I/O and Reference. For details, refer to

Setting the I/O Configuration

Setting the Logic Command and Reference

ATTENTION: Select and use either the point type Digital (LDO) or the word type Analog (LAO) as a control method, but

not both. Conflicts caused from using both methods can result in

dangerous operation. Failure to observe this precaution could cause bodily injury and/or damage to equipment.

On Siemens Building Technologies P1 FLN, there are two ways to control a drive and set its Reference.

• The more common way uses points such as CMD RUN.STOP (point 24)

and RUN ENABLE (point 26). Refer to Table 6.B on page 6-3 of points. For example, to start a PowerFlex 70/700 drive, you can set CMD RUN.STOP (point 24) to “RUN.” To stop it, you can set CMD RUN.STOP (point 24) to “STOP” or RUN ENABLE (point 26) to “STOP.”

on page 3-5.

for a list

ATTENTION: LOGIC CMD LO (point 89) must be written prior to LOGIC CMD HI (point 90) to maintain data integrity of

the Logic Command word. Failure to observe this precaution could result in bodily injury and/or damage to equipment.

• The second way uses LOGIC CMD HI (point 90) and LOGIC CMD LO

(point 89). The LOGIC CMD LO and LOGIC CMD HI points are both 8-bit points. The adapter joins these two words together to make a 16-bit command word. Refer to Appendix for definitions of the bits in the command word. The command word in the adapter’s buffer is updated with the content of LOGIC CMD LO and LOGIC CMD HI points. It is transferred to the drive when LOGIC CMD HI is written. Therefore, to maintain data integrity of the command word, LOGIC CMD LO must be written prior to writing LOGIC CMD HI. For example, to start a PowerFlex 70/700 drive, you can write a value of “2” to LOGIC CMD LO and a value of “0” to LOGIC CMD HI. To stop it, you can write a value of “1” to LOGIC CMD LO and a value of “0” to LOGIC CMD HI.

The Reference value is a 16-bit value in the drive but will only use 15 bits due to the P1 FLN protocol limitation. You can send the reference using REFERENCE (point 92). Remember that the Reference value is a scaled

engineering value. For example, in PowerFlex 70/700 drives, the Reference is scaled based on the value of Parameter 55 - [Maximum Freq], but the commanded maximum speed can never exceed the value of Parameter 82 - [Maximum Speed]. Table 6 .C on a PowerFlex 70/700 drive that has its Parameters 55 - [Maximum Freq] set to 130 Hz and 82 - [Maximum Speed] set to 60 Hz.

(1)

The drive runs at 60 Hz instead of 130 Hz because Parameter 82 - [Maximum Speed] sets 60 Hz as the maximum speed.

(2)

The Feedback value is also scaled based on the value of Parameter 55 - [Maximum Freq]. For example, 60/130 = 0.46 so 32767 x 0.46 = 15123.

The P1 FLN point map provides points to execute other commands on an adapter or drive. These points include CTRL ADDRESS (point 01), CURRENT LIMIT (point 30), ACCEL TIME (point 31), and DECEL TIME (point 32). Refer to Table 6.E on page 6-8 various points.

Viewing the Logic Status and Feedback

There are two ways to determine drive status:

• The more common way uses points such as RUN.STOP MON (point 23)

and FWD.REV MON (point 21) that represent individual bits in the Logic Status word. Refer to Table 6.B on page 6-3 example, to view if a PowerFlex 70/700 drive is running, you can read RUN.STOP MON (point 23) to see if it is “RUN” or “STOP.” To view its direction, you can read FWD.REV MON (point 21) to see if it is “FWD” or “REV.”

• The second way uses LOGIC STS LO (point 95) and LOGIC STS HI

(point 96). The LOGIC STS LO and LOGIC STS HI are both 8-bit points that the adapter can use to report its 16-bit status word. Refer to

Appendix

the status word. Since LOGIC STS LO gets updated only when LOGIC STS HI is read, you must read LOGIC STS HI prior to reading LOGIC STS LO to maintain the data integrity of the status word. For example, to view if a PowerFlex 70/700 drive is running, you can read LOGIC STS HI and LOGIC STS LO and determine if bit 1 is “0” (Not Running) or “1” (Running). To view its direction, you can read LOGIC STS LO and LOGIC STS HI and determine if bit 3 is “0” (Reverse) or “1” (Forward).

Using the P1 FLN Point Map to Access Parameters

The P1 FLN point map provides points to monitor a number of other features in the drive. These points include CURRENT (point 06), TORQUE (point 07), and POWER (point 08). Refer to Table 6.E the various points.

Drive parameters can be accessed using Configurable Points or Datalinks (Chapter 7

Reading Parameter Values

Configurable points USER IN (point 37) and PARAM IN (point 36) are points that enable any parameter in the drive to be monitored. The USER IN shows only 15-bit values; therefore, only 16-bit drive parameters can be used (however, only values between 0…32767 would be used).

The PARAM IN is used to configure which parameter is to be monitored, and the value ends up in the USER IN. For example, for a PowerFlex 70 or 700 drive, writing the value of “1” into PARAM IN point (reading drive parameter 1) would provide the Output Frequency in USER IN point.

20-COMM-H RS-485 HVAC Adapter User Manual

Publication 20COMM-UM009D-EN-P

6-10 Using Siemens Building Technologies P1 FLN

Writing Parameter Values

Configurable Points USER OUT (point 39) and PARAM OUT (point 38) are points that enable write access to any parameter in the drive. However, due to the 15-bit limitation, only 16-bit drive parameters should be accessed.

For example, for a PowerFlex 70/700 drive, writing a value of “140” in PARAM OUT (writing drive parameter 140) and the value of “200” in USER OUT would set drive Parameter 140 - [Accel Time 1] to 20.0 seconds.

ATTENTION: Risk of equipment damage exists. If configurable points are programmed to write parameter data to Non-Volatile Storage (NVS) frequently, the NVS will quickly exceed its life cycle and cause the drive to malfunction. Do not create a program that frequently uses configurable points to write parameter data to NVS. Datalinks do not write to NVS and should be used for frequently changed parameters.

7-1

Using Datalinks

A Datalink is a mechanism used by PowerFlex drives to transfer data to and from the controller. Datalinks “point” to specific drive parameters to be accessed. When enabled, each Datalink occupies two 16-bit or two 32-bit words in both the input and output image. Adapter Parameter 19 - [Datalink Size] indicates whether the drive uses 16-bit or 32-bit words for Datalinks.

Rules for Using Datalinks

• Each set of Datalink parameters in a PowerFlex drive can be used by

only one adapter. If more than one adapter is connected to a single drive, multiple adapters must not try to use the same Datalink.

• Parameter settings in the drive determine the data passed through the

Datalink mechanism. Refer to the documentation for your drive.

• When you use a Datalink to change a value, the value is NOT written to

the Non-Volatile Storage (NVS). The value is stored in volatile memory and lost when the drive loses power. Thus, use Datalinks when you need to change a value of a parameter frequently.

32-Bit Parameters using 16-Bit Datalinks

This subsection only pertains to PowerFlex 70 (SC or EC), PowerFlex 700 (SC), and PowerFlex 700H drives which use 16-bit Datalinks. To read (and/ or write) a 32-bit parameter using 16-bit Datalinks, typically both Datalinks of a pair (A, B, C, D) are set to the same 32-bit parameter. For example, to read Parameter 10 - [Elapsed Run Time] in a PowerFlex 70 drive, both Datalink A1 Out and Datalink A2 Out are set to “10.” Datalink A1 Out will contain the least significant word (LSW) and Datalink A2 Out will contain the most significant word (MSW).

20-COMM-H RS-485 HVAC Adapter User Manual

Publication 20COMM-UM009D-EN-P

7-2 Using Datalinks with All Protocols

32-bit data is stored in binary as follows:

MSW 231 through 2 LSW 215 through 2

In this example, the Parameter 10 - [Elapsed Run Time] value of 6553.9 Hrs is read as “6553.9” in Datalink A1 Out and Datalink A2 Out.

Datalink Word Parameter Data (Hex)

A1 Out LSW 10 0003 A2 Out MSW 10 0001

Conversion Example:

Parameter 010 - [Elapsed Run Time] = 6553.9 Hrs MSW = 0001 LSW = 0003 Engineering Value = 65536 + 3 = 65539 Parameter 10 Displayed Value = 6553.9 Hrs

Regardless of the Datalink combination, Datalink x1 Out will always contain the LSW and Datalink x2 Out will always contain the MSW. In the following example, the PowerFlex 70 drive Parameter 242 - [Power Up Marker] contains a value of 88.4541 hours.

Configuring Datalinks

Configuring Datalinks from the drive side is a two-step process:

1. Configure the datalink parameters in the drive. For example, in a PowerFlex 70 or 700 drive, set Parameters 300 - [Data In A1] to 317 - [Data Out D2] to “point” to the parameters to be accessed. For instance, to read drive Parameter 1 - [Output Freq], set Parameter

310 - [Data Out A1] to “1.”

2. Enable the desired Datalinks in Parameter 16 - [DPI I/O Cfg] in the

adapter. This tells the adapter to transfer Datalink data to and from the drive. For example, to enable Datalink A1, set bit 1 to “1.” For details, refer to Setting the I/O Configuration

7-6 Using Datalinks with All Protocols

Note that certain drives may utilize 32-bit datalinks. In this case, Datalinks are not supported by the adapter. The adapter will support only 15-bit Datalink values.

ATTENTION: Risk of injury or equipment damage exists. On P1 FLN networks, 16-bit values are truncated to 15-bit values.

Unpredictable operation may result from using non-16-bit drive parameters with the configurable points. Recognize the data range limitation of P1 FLN and understand the data value ranges of each parameter to be accessed over the network. Refer to the drive user manual for information about drive parameter sizes.

Siemens P1 FLN Datalinks Out: A…D

P1 FLN devices work only with 15-bit integer values; therefore, these points only show 15-bit values. If an adapter is connected to a host using 32-bit Datalinks, the adapter will be prevented from using Datalinks. The DPI host determines if 16- or 32-bit Datalink values are used.

Viewing and Clearing Events

The adapter has an event queue to record significant events that occur in the operation of the adapter. When such an event occurs, an entry is put into the event queue. You can view the event queue using an LCD PowerFlex 7-Class HIM, DriveExplorer (2.01 or higher) software, DriveExecutive (1.01 or higher) software or other clients using the DPI Fault object.

The event queue can contain up to 32 entries. Eventually the event queue will become full, since its contents are retained through adapter resets. At that point, a new entry replaces the oldest entry. Only an event queue clear operation or adapter power cycle will clear the event queue contents.

Resetting the adapter to defaults has no effect on the event queue.

20-COMM-H RS-485 HVAC Adapter User Manual

Publication 20COMM-UM009D-EN-P

A Adapter

Devices such as drives, controllers, and computers usually require an adapter to provide a communication interface between them and a network. An adapter reads data on the network and transmits it to the connected device. It also reads data in the device and transmits it to the network.

The 20-COMM-H RS-485 HVAC adapter connects a PowerFlex 7-Class drive to the network. Adapters are sometimes also called “cards,” “embedded communication options,” “gateways,” “modules,” and “peripherals.”

B Bus Off

A condition that occurs when an abnormal rate of errors is detected in a device. The bus off device cannot receive or transmit messages on the network. This condition is often caused by corruption of the network data signals due to noise or data rate mismatch.

C ControlFLASH

An Allen-Bradley software tool that lets users electronically update firmware on printed circuit boards. The tool takes advantage of the growing use of flash memory (electronic erasable chips) across industrial control products.

Glossary

D Data Rate

Controller

A controller, also called programmable logic controller, is a solid-state control system that has a user-programmable memory for storage of instructions to implement specific functions such as I/O control, logic, timing, counting, report generation, communication, arithmetic, and data file manipulation. A controller consists of a central processor, input/output interface, and memory. See also Scanner.

The speed at which data is transferred on the network. Each device on a network must be set to the same data rate.

Datalinks

A Datalink is a type of pointer used by some PowerFlex drives to transfer data to and from the controller. Datalinks allow specified parameter value(s) to be accessed or changed without using explicit messages. When enabled, each Datalink consumes either four bytes or eight bytes in both the input and output image table of the controller. The drive determines the size of Datalinks.

DPI (Drive Peripheral Interface)

A second generation peripheral communication interface used by various Allen-Bradley drives and power products, such as PowerFlex 7-Class drives.

20-COMM-H RS-485 HVAC Adapter User Manual

Publication 20COMM-UM009D-EN-P

G-2 Glossary

DPI Peripheral

A device that provides an interface between DPI and a network or user. Peripheral devices are also referred to as “adapters” or “modules.” The 20-COMM-H adapter and PowerFlex 7-Class HIMs (20-HIM-xxx) are examples of DPI peripherals.

DPI Product

A device that uses the DPI communications interface to communicate with one or more peripheral devices. For example, a motor drive such as a PowerFlex 7-Class drive is a DPI product. In this manual, a DPI product is also referred to as “drive” or “host.”

DriveExplorer Software

A tool for monitoring and configuring Allen-Bradley products and adapters. It can be run on computers running various Microsoft Windows operating systems. DriveExplorer (version 3.xx or higher) can be used to configure this adapter and PowerFlex drive. Information about DriveExplorer software and a free lite version can be accessed at http://www.ab.com/

drives/driveexplorer.

DriveTools SP Software

A software suite designed for running on various Microsoft Windows operating systems. This software suite provides a family of tools, including DriveExecutive, that you can use to program, monitor, control, troubleshoot, and maintain Allen-Bradley products. DriveTools SP can be used with PowerFlex drives. Information about DriveTools SP can be accessed at

http://www.ab.com/drives/drivetools

F Fault Action

A fault action determines how the adapter and connected drive act when a communications fault (for example, a cable is disconnected) occurs.

Fault Configuration

When communications are disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond with a user-defined fault configuration. The user sets the data that is sent to the drive using specific fault configuration parameters in the adapter. When a fault action parameter is set to use the fault configuration data and a fault occurs, the data from these parameters is sent as the Logic Command, Reference, and/or Datalink(s).

Flash Update

The process of updating firmware in a device. The adapter can be flash updated using various Allen-Bradley software tools. Refer to Flash

Updating the Adapter on page 3-10 for more information.

20-COMM-H RS-485 HVAC Adapter User Manual

Publication 20COMM-UM009D-EN-P

Glossary G-3

H HIM (Human Interface Module)

A device that can be used to configure and control a drive. PowerFlex 7-Class HIMs (20-HIM-xxx) can be used to configure PowerFlex 7-Class drives and their connected peripherals.

Hold Last

When communication is disrupted (for example, a cable is disconnected), the adapter and PowerFlex drive can respond by holding last. Hold last results in the drive receiving the last data received via the network connection before the disruption. If the drive was running and using the Reference from the adapter, it will continue to run at the same Reference.

I I/O Data

I/O data, sometimes called “ implicit messages” or “input/output,” is time-critical data such as a Logic Command and Reference. The terms “input” and “output” are defined from the controller’s point of view. Output is produced by the controller and consumed by the adapter. Input is produced by the adapter and consumed by the controller.

L Logic Command/Logic Status

The Logic Command is used to control the PowerFlex 7-Class drive (for example, start, stop, direction). It consists of one 16-bit word of output to the adapter from the network. The definitions of the bits in this word depend on the drive, and are shown in Appendix

The Logic Status is used to monitor the PowerFlex 7-Class drive (for example, operating state, motor direction). It consists of one 16-bit word of input from the adapter to the network. The definitions of the bits in this word depend on the drive, and are shown in Appendix

N Node Address

Each device on a network must have a unique node address to identify it. On Modbus RTU, Metasys N2, and Siemens Building Technologies P1 FLN networks, devices can have node addresses between 1 and 255 if the network is set up to accommodate that number of devices.

NVS (Non-Volatile Storage)

NVS is the permanent memory of a device. Devices such as the adapter and drive store parameters and other information in NVS so that they are not lost when the device loses power. NVS is sometimes called “EEPROM.”

P Parity Check

When the adapter uses a parity check, a non-data bit is added to each binary word that it sends and receives. Devices on the network verify the data integrity of the transmitted data by checking that the sum of the number of ones in a word is always even or odd.

20-COMM-H RS-485 HVAC Adapter User Manual

Publication 20COMM-UM009D-EN-P

G-4 Glossary

Ping

A message that is sent by a DPI product to its peripheral devices. They use the ping to gather data about the product, including whether it can receive messages and whether they can log in for control.

PowerFlex 7-Class (Architecture Class) Drives

The Allen-Bradley PowerFlex 7-Class family of drives supports DPI and includes the PowerFlex 70, PowerFlex 700, PowerFlex 700H, PowerFlex 700S, PowerFlex 700L, and PowerFlex 7000. These drives can be used for applications ranging from 0.37…3000 kW (0.5…4000 HP).

R Reference/Feedback

The Reference is used to send a setpoint (for example, speed, frequency, torque) to the drive. It consists of one word of output to the adapter from the network. The size of the word (either a 16-bit word or 32-bit word) is determined by the drive.

Feedback is used to monitor the speed of the drive. It consists of one word of input from the adapter to the network. The size of the word (either a 16-bit word or 32-bit word) is determined by the drive.

S Scanner

A scanner is a separate module (of a multi-module controller) or a built-in component (of a single-module controller) that provides communication with adapters connected to a network. See also Controller.

Status Indicators

Status indicators are LEDs that are used to report the status of the adapter, network, and drive. They are on the adapter and can be viewed on the front cover of the drive when the drive is powered.

T Type 0/Type 1/Type 2 Control

When transmitting I/O, the adapter can use different types of messages for control. The Type 0, Type 1, and Type 2 events help Allen-Bradley personnel identify the type of messages that an adapter is using.

Z Zero Data

When communications are disrupted (for example, a cable is disconnected), the adapter and drive can respond with zero data. Zero data results in the drive receiving zero as values for Logic Command, Reference, and Datalink data. If the drive was running and using the Reference from the adapter, it will stay running but at zero Reference.
