ProSoft Technology, Inc. Page 18 of 53
2.3 [PROFIBUS SLAVE]
The PROFIBUS Slave section contains PROFIBUS Slave parameter data.
2.3.1 Slave Address
0 to 125
The parameter specifies the node address on the PROFIBUS network for the slave
emulated in the module. Each node on the network must have a unique address.
Note: Although valid PROFIBUS Node addresses range from 0 to 125, Node 0 is not a valid node number
for a Slave module and that Nodes 0, 1, and 2 are usually reserved for PROFIBUS Masters. Users are
advised to use Node numbers 3-125
2.3.2 Swap Input Bytes
Yes or No
This parameter specifies if the data in the input data area of the module is to be byte
swapped. If the order of the bytes in the words stored in the database is not correct, use
this option. A value of Yes causes the module’s program to swap the bytes in each word.
A value of No indicates no byte swapping will occur.
2.3.3 Swap Output Bytes
Yes or No
This parameter specifies if the data in the output data area of the module is to be byte
swapped. If the order of the bytes in the words stored in the database is not correct, use
this option. A value of Yes causes the module’s program to swap the bytes in each word.
A value of No indicates no byte swapping will occur.
2.3.4 Comm Failure Mode
No xfer on fail
Xfer on comm fail
This parameter sets the data transfer mode of the module's PROFIBUS output image to the
internal database upon PROFIBUS communication failure.
If the parameter is set to "No xfer on fail", the output image will not be transferred and the
last values will be retained.
If the parameter is set to "xfer on comm fail", the output image will continue to be transferred.
2.3.5 Comm Timeout Multiplier
1 to 10
This parameter sets the communication timeout value for the module. The value entered is
multiplied by 125 milliseconds to determine the actual timeout value. For example, a value of
1 specifies a communication timeout of 125 milliseconds.
