Configuring the Adapter 3-3

Setting the I/O Configuration

The I/O configuration determines the data that is sent to and from the drive. This is a two part process: enabling/disabling the data transmitted between the adapter and drive, and identifying the data transmitted between the adapter and the scanner.

1. Enable or disable the data transmitted between the adapter and drive.

A “1” enables the I/O A “0” disables the I/O

Set the bits in Parameter 8 - [DPI I/O Config]:

Bit Description

0 Logic Command/Reference (Default) 1 Datalink A 2 Datalink B 3 Datalink C 4 Datalink D 5 - 16 Not Used

Bit 0 is the right-most bit. In Figure 3.1, it is highlighted and equals “1.”

2. If Logic Command/Reference is enabled, configure the parameters in

the drive to accept the logic and Reference from the adapter. For example, set Parameter 90 - [Speed Ref A Sel] in a PowerFlex 70 or 700 drive to “DPI Port 5” so that the drive uses the Reference from the adapter. Also, verify that the mask parameters (for example, Parameter 276 - [Logic Mask]) in the drive are configured to receive the desired logic from the adapter.

3. If you enabled one or more Datalinks, configure parameters in the

drive to determine the source and destination of data in the Datalink(s). Also, ensure that the Interbus adapter is the only adapter using the enabled Datalink(s).

3-4 Configuring the Adapter

4. Interbus requires the network I/O mapping to be configured first in

the adapter. CMD software will read this configuration online when it is configuring the scanner.

Process Input Data Description (PIDD) words map input data on the network (data seen as inputs to the scanner and controller program). Example input data includes Logic Status, Feedback and Datalinks (Datalink x1 Out). Up to 9 words of input data can be mapped.

Process Output Data Description (PODD) words map output data on the network (data sent as outputs from the scanner and controller program). Example output data includes Logic Command, Reference and Datalinks (Datalink x1 In). Up to 9 words of output data can be mapped.

The following indexes are used to select the I/O data:

4-4 Configuring the Interbus Scanner

Using CMD Software to Configure the Network

Before starting the configuration, make sure the PC running CMD software is connected to the SST scanner (a null modem cable is supplied with the scanner). The SLC and drives need to be connected to the Interbus network and powered in order for CMD to configure the network. If it does not already exist, CMD software tool automatically creates an Allen-Bradley sub-folder (in the Slaves folder).

CMD needs to be in Extended Mode to configure the network. A password (supplied by Phoenix Contact along with the CMD software), is requested for this functionality each time CMD is started. After CMD has started, you can also click O enter the password.

About I/O Messaging

On Interbus, I/O messaging is used to transfer the data which controls the PowerFlex drive and sets its Reference. I/O can also be used to transfer data to and from Datalinks in PowerFlex drives.

The Interbus adapter provides options for configuring and using I/O, including the following:

• The size of I/O can be configured by enabling or disabling the Logic Command/Reference and Datalinks.

Chapter Interbus Scanner discuss how to configure the adapter and scanner on the

network for these options. The Glossary defines the different options. This chapter discusses how to use I/O after you have configured the adapter and scanner.

5-2 Using I/O Messaging

Understanding the I/O Image

The terms input and output are defined from scanner’s point of view. Therefore, Output I/O is data that is output from the scanner and consumed by the Interbus adapter. Input I/O is status data that is produced by the adapter and consumed as input by the scanner. The I/O image table will vary based on the following:

• Size (either 16-bit or 32-bit) of the Reference/Feedback word and Datalink words used by the drive.

• Configuration of Parameter 8 - [DPI I/O Config] in the adapter. If all I/O is not enabled, the image table is truncated. The image table always uses consecutive words starting at word 0.

5-4 Using I/O Messaging

Using Logic Command/Status

When enabled, the Logic Command/Status word is always word 0 in the I/O image. The Logic Command is a 16-bit word of control produced by the scanner and consumed by the adapter. The Logic Status is a 16-bit word of status produced by the adapter and consumed by the scanner.

This manual contains the bit definitions for compatible products available at the time of publication in Appendix

Status Words. For other products, refer to their documentation.

Using Reference/Feedback

When enabled, Reference/Feedback always begins at word 1 in the I/O image. The Reference (16 bits or 32 bits) is produced by the controller and consumed by the adapter. The Feedback (16 bits or 32 bits) is produced by the adapter and consumed by the controller. The size of the Reference/Feedback is determined by the product and displayed in Parameter 03 - [Ref/Fdbk Size] in the adapter.

Size Valid Values In I/O Image Example

16-bit -32768 to 32767 Word 1 Figure 5.1 32-bit -2147483648 to 2147483647 Word 1 and Word 2 Figure 5.2

C, Logic Command/

Using Datalinks

A Datalink is a mechanism used by PowerFlex drives to transfer data to and from the controller. Datalinks allow a parameter value to be changed without using an Explicit Message. When enabled, each Datalink consumes either two 16-bit or 32-bit words in both the input and output image depending on its size. The size of Datalinks (16-bit words or 32-bit words) is determined by the drive and displayed in Parameter 04

- [Datalink Size] in the adapter.

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 product.

• 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.

Using I/O Messaging 5-5

32-Bit Parameters using 16-Bit Datalinks

To read (and/or write) a 32-bit parameter using 16-bit Datalinks, typically both Datalinks (x1 and x2) are set to the 32-bit parameter. For example, to read Parameter 09 - [Elapsed MWh] in a PowerFlex 70, both Datalink A1 and A2 are set to “9”. Datalink A1 will contain the least significant word (LSW) and Datalink A2 the most significant word (MSW). In this example, the parameter 9 value of 5.8MWh is read as a “58” in Datalink A1.

Datalink Most/Least Significant Word Parameter Data (decimal)

A1 LSW 9 58 A2 MSW 9 0

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

Datalink Most/Least Significant Word Parameter Data (decimal)

A1 LSW 242 32573 A2 - Not Used - 0 0

Datalink Most/Least Significant Word Parameter Data (decimal)

A1 - Not Used - 0 0 A2 MSW 242 13

Datalink Most/Least Significant Word Parameter Data (decimal)

A2 MSW 242 13 B1 LSW 242 32573

32-bit data is stored in binary as follows:

MSW 2

LSW 215 through 2

through 2

Example: Parameter 242 - [Power Up Marker] = 88.4541 hours

MSW = 13

decimal

= 1101

= 219 + 218 + 216 = 851968

ATTENTION: Risk of equipment damage exists. If Explicit Messages 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 Explicit Messages to write parameter data to NVS. Datalinks do not write to NVS and should be used for frequently changed parameters.

About Explicit Messaging

Explicit Messaging (PCP Communications) is used to transfer data that does not require continuous updates. With Explicit Messaging, you can configure and monitor a slave device’s parameters on the Interbus network.

To be able to use Explicit Messaging in the adapter, Parameter 57 - [PCP Comm Act] must be set to “Enabled”.

Running Explicit Messages

There are five basic events in the Explicit Messaging process defined below. The details of each step will vary depending on the controller. Refer to the documentation for your controller.

Important: There must be a request message and a response message

for all Explicit Messages, whether you are reading or writing data.

1. Format the required data and set up the ladder logic program to send

an Explicit Message request to the scanner module (download).

2. The scanner module transmits the Explicit Message Request to the

slave device over the Interbus network.

3. The slave device transmits the Explicit Message Response back to

the master.

4. The controller retrieves the Explicit Message Response.

5. The Explicit Message is complete.

Using Explicit Messaging (PCP Communications) 6-3

PCP Communications

Peripheral Communications Protocol (PCP) messages are used for explicit messaging, which is not part of the normal Interbus I/O data scan. The scanner takes care of all of the details of establishing a connection for PCP communication services. PCP communications can be used to:

• Read or write DPI Host (PowerFlex 70, etc.) parameters

• Read or write 20-COMM-I parameters

• Read DPI Host (PowerFlex 70, etc.) faults

• Read 20-COMM-I events

The Command Interface for the SST SLC Interbus scanner must be enabled for PCP Communications to take place:

• Bit 12 of word 1 in the G File must be set

• Word 5 in the G File must be set to the length of process data

required in the M Files. This value can range from 0 to 224

• Word 6 in the G File must be set to the maximum length of the command buffer. This value can range from 0 to 128 and must be non-zero to enable the buffer.

The ladder example used in this manual uses Input (I:) and Output (O:) files for I/O messaging (Logic Command/Status, Reference/ Feedback, and Datalinks) and M Files for PCP messaging (See Chapter

4, RSLogix 500 SST Interbus Scanner

Configuration.)

The first word in the Command Interface memory area is the Command (M0) or Status (M1) word. The remaining words form a buffer to pass command data to and from the scanner. The M0 file contains the buffer for the command written by the SLC and the M1 file contains the reply to the SLC written by the scanner.

The lower six bits in the Command word are command bits to the scanner. Commands are initiated by setting bits in this Command word. The scanner acknowledges the command by setting bits in the Status word. The high bit is either the Message Acknowledge bit (command word) or the Message Present bit (Status word).

6-6 Using Explicit Messaging (PCP Communications)

The example ladder logic program simplifies addressing the various PCP indexes. Before calling the PCP Read Subroutine (Figure 6.3), three registers are loaded to identify the variable to be read:

Table 6.2 PCP Read Main Program Data

N22:0

N22:1

N22:2

The Communication Reference (CR) to read from:

Set to “2” to access Station 1.0 (CR=2) Set to “3” to access Station 2.0 (CR=3)

The desired Parameter / Event / Fault area to be accessed:

Set to “0” to read PowerFlex 70 parameters Set to “1” to read 20-COMM-I parameters Set to “2” to read PowerFlex 70 Fault Queue Set to “3” to read 20-COMM-I Event Queue

The actual Parameter number or Event / Fault Queue item number to read. Set to “1” to read Parameter number 1 or Fault / Event

Queue item number 1....etc....

The PCP Read Subroutine uses the data in Table 6.2 to create the

following Command Message:

Table 6.3 PCP Read Subroutine Command Message

N22:10 The PCP Command word (set to “4” for PCP Read). N22:11 The Communication Reference (CR) to read from. N22:12 The PCP Index of the variable to read (“3001h”= Host parameter 1, etc.). N22:13 Sub Index not used (set to “0”).

Using Explicit Messaging (PCP Communications) 6-11

The example ladder logic program simplifies addressing the various PCP indexes. Before calling the PCP Write Subroutine (Figure 6.4), six registers are loaded to identify the variable to write:

Table 6.5 PCP Write Main Program Data

N23:0

N23:1 The desired parameter area to be accessed:

N23:2 The actual parameter number to write to (1, 2, ....n).

N23:3 The number of bytes of data to write:

N23:4 Data Word #1

N23:5 Data Word #2

The Communication Reference (CR) to write to:

Set to “2” to access Station 1.0 (CR=2) Set to “3” to access Station 2.0 (CR=3)

Set to “0” for DPI Host parameters Set to “1” for 20-COMM-I parameters

Set to either “1” (1 byte), “2” (2 bytes) and “4” (4 bytes)

(1 and 2-byte writes, MSW of 4 byte write).

(LSW of 4-byte write).

The PCP Write Subroutine uses the data in Table 6.5 to create the following Command Message:

Table 6.6 PCP Write Subroutine Command Message

N23:10 The PCP Command word (set to “8” for PCP Write). N23:11 The Command Reference (CR) to write to. N23:12 The PCP Index of the variable to write (“306Ah” = Host parameter 106,

N23:13 Sub Index not used. N23:14 The number of bytes of data to write (set to “1”, “2” or “4”). N23:15 Data word 1. N23:16 Data word 2.

etc.).

Note that writing to parameters causes a non-volatile storage (NVS) write cycle and therefore must NOT be done frequently (can exceed the maximum number of allowable write cycles and cause the product to malfunction).

Table 6.7 PCP Write Subroutine Reply Message

N23:20 = PCP Status Word. N23:21 = Echo of the Command word (0008h). N23:22 = Number of words following. N23:23 = CR. N23:24 = Result (“0” = good).

B-1

The adapter parameters begin with parameter 1. For example, Parameter 01 - [DPI Port] is parameter 1 as indicated by this manual.

Parameters List

Parameter No. Name and Description Details

01 [DPI Port]

Port to which the adapter is connected. This will usually be port 5.

02 [DPI Data Rate]

Data rate used by the drive. This data rate is set in the drive, and the adapter detects it.

03 [Ref/Feedback Size]

Size of the Reference/Feedback. The drive determines the size of the Reference/Feedback.

Default: 0 Minimum: 0 Maximum: 7 Type: Read Only

Default: 0 = 125 K Values: 0 = 125 K

Type: Read Only Default: 0 = 16-bit

Values: 0 = 16-bit

Type: Read Only

1 = 500 K

1 = 32-bit

B-2 Adapter Parameters

Parameter No. Name and Description Details

04 [Datalink Size]

Size of each Datalink word. The drive determines the size of the Datalinks.

05 [Reset Module]

No action if set to “Ready.” Resets the adapter if set to “Reset Module.” Restores the adapter to its factory default settings if set to “Set Defaults.” This parameter is a command. It will be reset to “0 = Ready” after the command has been performed.

06 [Comm Flt Action]

Action that the adapter and drive take if the adapter detects that Interbus communications have been disrupted. This setting is effective only if I/O that controls the drive is transmitted through the adapter.

ATTENTION: Risk of injury or equipment damage exists. Parameter 6 - [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 hazard or injury or equipment damage.
