Configuring a PROFIBUS Slave Module
The PROFIBUS Slave module has four Parameters tabs: Settings, Input Data Area,
Output Data Area, and Power Consumption.
Settings Tab
Station | The Slave module’s station number that is used on the PROFIBUS network. Can be in the range |
| from 1 to 125. Each module on a network should be given a unique station number. Default is 1. |
| Note that the Master is commonly assigned to Station 0 (zero). |
Baud Rate | Specifies the data transmission rate for the PROFIBUS Slave module in bits/second (bps). |
| Values: 9.6Kbps, 19.2KBps, 93.75KBps, 187.5KBps, 500KBps, 1.5MBps, 3MBps, 6Mbps, |
| 12MBps |
Default: 1.5MBps
Note: The Horner PROFIBUS Slave module, HE693PBS105, does not have this setting. If you are converting from a Horner module to a Series
Status/Firmware This is the starting address for this
ID Address range and as such must be a
The Status word provides information about the status of the PBS201 module to the PLC CPU. For more information, see “Get Slave Status Reply Data Format” in chapter 4.
The Firmware ID word contains the current firmware version running on the PBS201. The Major Revision number resides in the upper byte and the Minor Revision number resides in the lower byte of this word.
Tip: Use the Communication Request (COMMREQ) task 3 (GetSlaveStatus) to retrieve the information that is reported in this memory area. (This COMMREQ is sent from the CPU of the PLC where the Slave module resides.)
Length | Always two words. (A value of 2 for register memories and 32 for discrete memories.) |
Inputs on Loss of | Determines what values are used for the data received by the module from the master (inputs to |
Master | the Slave module/outputs from the master) if communication with the master is lost. |
Choices are:
Hold Last State (default) – Until communication resumes and new values are received, each input will have the value that it had when communication was lost.
Clear – Until communication resumes and new values are received, each input will have a value of 0.
