Page 8: About The Anybus-S Interbus 2Mbit/S Rs422
About the Anybus-S Interbus 2Mbit/s RS422 The Anybus-S Interbus 2Mbit/s module is a slave node that can be read from/written to by an Interbus master. Being a slave module, it cannot initiate communication to other nodes; it only responds to in- coming requests. -

About the Anybus-S Interbus 2Mbit/s RS422 1-2 Status Indicators These LEDs indicate run time status and errors to the user. Colour Description 1 - CC/RC Green Cable connection is good and the Interbus master is not in reset mode. 2 - BA... -
Page 10: Data Exchange
Chapter 2 Data Exchange The module can use both fast I/O data and Parameter data. On the Interbus network, Fast I/O data is represented as Process Data, while Parameter Data is represented as PCP data. On InterBus, there is an equal amount of Input and Output Process Data. -
Page 11: Fieldbus Specific Mailbox Commands
Chapter 3 Fieldbus Specific Mailbox Commands Alter amounts of PCP words (SET_PCP_WORDS) The amount of PCP words can be set to 0, 1, 2 or 4 words. If parameter data has been selected by the Anybus_INIT command, one PCP word is used by default. If no parameter data has been selected, the default number of PCP words is 0. -

Fieldbus Specific Mailbox Commands 3-2 Set the Virtual Field Device Object (SET_VFD_OBJECT) The Virtual Field Device Object can be altered to show other manufacturer, device name and revision strings than the ones that are shown by default. The strings should be entered in Pascal notation, i.e. the length of the string (no. -
Page 13: Set Start Index (Set_Start_Index)
Fieldbus Specific Mailbox Commands 3-3 Set Start Index (SET_START_INDEX) If the PCP objects are to be redefined, it is also possible to change the start index from which they orig- inate. This mailbox has to be transmitted prior to sending down the mailbox command “Set PCP Ob- ject”. -
Page 14: Set Pcp Object (Set_Pcp_Object)
Fieldbus Specific Mailbox Commands 3-4 Set PCP Object (SET_PCP_OBJECT) The object dictionary of the Anybus-S Interbus module can be changed to better suit the needs of a spe- cial implementation which uses the module. After setting a start index, new objects can be downloaded to the module. - Page 15 Fieldbus Specific Mailbox Commands 3-5 Command and response layout: Command Expected response Message ID (ID) (ID) Message information 4002h 0002h Command 0004h 0004h Data size 0017h 0017h Frame count 0001h 0001h Frame number 0001h 0001h Offset high 0000h 0000h Offset low 0000h 0000h Extended word 1...

Page 17: Set The Pdu Sizes (Set_Pdu_Sizes)
Fieldbus Specific Mailbox Commands 3-7 Set the PDU sizes (SET_PDU_SIZES) This mailbox sets the sizes of the input and output PDU (Protocol Data Unit), which sets up the trans- mit and receive buffers used for PCP communication. In case larger objects are to be downloaded by the SET_PCP_OBJECT mailbox, it might be necessary to increase the PDU-sizes. -
Page 18: Set Module Function (Set_Mod_Func)
Fieldbus Specific Mailbox Commands 3-8 Set Module Function (SET_MOD_FUNC) This mailbox is used to set the identity of the Interbus interface. It can only be sent during initialization. Note: The mailbox does not check that the Module Function that is set, has any correspondence in re- ality. -

Non Operating -15 to +85 degrees Celsius Test performed according to IEC-68-2-1 and IEC 68-2-2. Relative Humidity The product is designed for a relative humidity of 5 to 95% non condensing. Test performed according to IEC 68-2-30. -
Page 24: Supply Voltage
Appendix D Electrical Characteristics Supply Voltage Both the module electronics and the fieldbus interface requires a regulated 5V DC power supply. For more information regarding power requirements, consult the Anybus-S Parallel Design Guide. Power Consumption The maximum total power consumption for bus and electronics is 400mA. PE Grounding A PE-connection is included on one of the mounting holes according to the Anybus-S specification. - Page 25 Appendix D Calculating the PCP Transmission Time The formula below can be used to calculate the transmission time for a PCP message. Formula: TD = TL + Gm( OD, N ) * Z + TL7 Gm = ( OD, N ) = (( N + OD - 1 ) / m ) + 1 Transmission time of a PCP service in milliseconds Latency 2 * Z (milliseconds) Service dependent overhead...
