20COMM-UM007A-EN-P.book Page 4 Tuesday, January 22, 2002 10:52 AM 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).

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.

20COMM-UM007A-EN-P.book Page 4 Tuesday, January 22, 2002 10:52 AM 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.

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).

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. Figure 6.

20COMM-UM007A-EN-P.book Page 1 Tuesday, January 22, 2002 10:52 AM Glossary A Adapter Devices such as drives, controllers, and computers usually require an adapter to provide a communication interface between them and a network such as Interbus. 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-I Interbus adapter is an adapter that connects, PowerFlex drives to a Interbus network.
PAGE 107
20COMM-UM007A-EN-P.book Page 2 Tuesday, January 22, 2002 10:52 AM Glossary-2 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.
PAGE 108
20COMM-UM007A-EN-P.book Page 3 Tuesday, January 22, 2002 10:52 AM Glossary-3 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 in the fault configuration parameters (Parameters 10- [Flt Cfg Logic] through 19- [Flt Cfg D2In]).

20COMM-UM007A-EN-P.book Page 4 Tuesday, January 22, 2002 10:52 AM Glossary-4 L Logic Command/Logic Status The Logic Command is used to control the PowerFlex drive (e.g., start, stop, direction). It consists of one 16-bit word of input to the adapter from the network. The definitions of the bits in this word depend on the drive. The Logic Status is used to monitor the PowerFlex drive (for example, operating state, motor direction). It consists of one 16-bit word of output from the adapter to the network.

20COMM-UM007A-EN-P.book Page 5 Tuesday, January 22, 2002 10:52 AM Glossary-5 PODD Process Output Data Description words are used for mapping output data on the network. Example output data includes Logic Command, Reference, and Datalinks (Datalink x1 In). R Reference/Feedback The Reference is used to send a Reference (for example, speed, frequency, torque) to the product. It consists of one word of input to the adapter from the network.
