If the power-up sequence fails, the TR LED will go to off and the module will enter the Error Mode (see below). Run Mode After a successful power-up, the IB1 Module enters the run mode and operates as a slave device to a master device (BA LED on).
Chapter 5 InterBus Parameter Descriptions and Data Protocol This chapter provides a listing and description of the Bulletin 160 Drive parameters related to Network Operation, and the IB1 Module Data Protocol information. Important: Refer to your 160 SSC™ Variable Speed Drive (Series C) User Manual for drive parameter descriptions.
5–2 InterBus Parameter Descriptions and Data Protocol InterBus Data Protocol Data Channels The data transfer in Interbus terminology is called Peripherals Communications Protocol (PCP). Process data and parameter data is transmitted in the InterBus system via two independant transmission channels. i.e. the process data channel and the parameter data channel. The process data channel cyclically transmits process data in the form of an I/O image.
InterBus Parameter Descriptions and Data Protocol Data from IB1 Slave to InterBus Master 5–3 Speed Feedback, displayed by Register 1, is scaled in RPM according to P66 - [RPM Scaling]. Table 5.B Register No. 0 1 2 Control and Status Word DRIVECOM 20/21 Register (Words) Status Word Speed Feedback Diagnostics Description According to DRIVECOM 20 160 Drive Output Frequency (motor RPM) reserved Control and Status word bits are defined as follows (speed control): Table 5.

InterBus Parameter Descriptions and Data Protocol Parameter Access 5–5 Parameter access is established by object indices and parameter related sub-indices to be sent via the PCP telegram. Table 5.
5–6 InterBus Parameter Descriptions and Data Protocol Communication Statistics The following communication statistics can be read via the InterBus Register 3 from the Network option. Table 5.
Chapter 6 Using the 160-IB1 on InterBus The purpose of this chapter is to provide an example of the steps necessary to use the 160-IB1 on an InterBus network. As InterBus is a 3rd party network, we will be using an SST-IBS-SLC scanner to act as a master for InterBus, residing in an A-B SLC500 rack. The SST scanner sends I/O messages periodically to a Bulletin 160-IB1 to start and stop the drive and control its speed.
6–2 Using the 160-IB1 on InterBus Create an InterBus Network Configuration Frame This example assumes that the SLC 500 rack has been configured correctly with the SST-IBS-SLC card in slot 3. If configuration is required an example of configuration is shown further in this chapter – The InterBus PCP Telegram. Additionally it is assumed that a 160 drive with an 160-IB1 interface is connected on the InterBus remote bus with a relevant 9 way D shell connector (see chapter 3).
Using the 160-IB1 on InterBus 6–3 Click (select) the controller board and right mouse click ”type” to select the type of scanner. Click IBS USC(4K) as the controller type and click ok. With the ”controller board” selected, hit F3 on your PC (the state button). Select Configuration (on-line) and click ok. If the processor is faulted, you will not be able to go on-line. So put the processor into program mode with the keyswitch., then select Configuration (on-line).
6–4 Using the 160-IB1 on InterBus . Look at the LED’s on the 160-IB1 module, BA is flashing, indicating that the module is not being controlled by anything. Now with the controller still selected, right click and choose ”Parameterization” and ”Edit” to specify how we want the scanner to start up. Select ”Startup without PDP” and uncheck ”start data transmission” (action 23) and click ok.
Using the 160-IB1 on InterBus 6–5 Now save the file with a filename. Choose ”File” and ”Save” commands. The network should now be configured with the 160-IB1 BA LED now steady green. If not, check that the processor is in Run mode. InterBus assigns a communication reference (CR) dynamically when the network(frame) is read in. It starts with the first module it sees on the network, assigns a CR=2 and specifies memory allocation for the I/O messaging.
6–6 Using the 160-IB1 on InterBus Controlling the Drive with I/O Messaging Now adjust the drive parameters as defined in chapter 5 of this manual in order to test the drive with the following program example: Figure 6.1 Drive Test Program Ladder Logic Example.

6–8 Using the 160-IB1 on InterBus The InterBus PCP Telegram The Peripherals Communication Protocol (PCP) of InterBus supports 2 different types of independent data transmission. The 3 words that were mapped previously in this chapter, is the process data channel which is the cyclic transmitted I/O data to start/ stop the drive and provide reference and feedback. The parameter data channel is much slower, working around the process data channel, to read/write parameters to the drive.
Using the 160-IB1 on InterBus 6–9 Select the Advanced Config button, to setup the card as shown. This means that there are 32 words reserved for process data (I/O) and the M files are set to 384 words. To make PCP function we need to setup the G files with data . So the G files length = 7. Select the Edit G file data button, to setup the data for the InterBus telegram.
6–10 Using the 160-IB1 on InterBus This is an example of a read drive parameter (all values in hex) The first node on the network is a communication reference (CR) = 2, with the parameter read access index of 5FF0 (see table 5E) and the sub-index specifying parameter 8 [Heatsink Temperature].
Using the 160-IB1 on InterBus Reading and Configuring Parameters with the PCP Telegram 6–11 Figure 6.2 PCP Telegram Ladder Logic Example This program example can be made to operate by first setting I:1.4 to request a read or write operation, the setting B3:20 bit 0 to 1 to update the data in N7:70 onwards into the M0 files, then setting B3:20 bit 1 to 1 to send the data.

Chapter 7 Controlling the Drive Controlling the 160 Drive from a programmable controller is accomplished using Message Commands to communicate through the IB1 Module to the drive. To send a Start or Stop command to the drive, the corresponding control bits in the DRIVECOM Control Word must be set. Setting the Drive to Enable Network Control The 160 Drive must be configured to accept logic and speed commands from the network. This is done by configuring three parameters: 1.
