3.3 [PROFIBUS SLAVE]
The PROFIBUS Slave section contains the data that applies to the PROFIBUS
Slave parameters.
3.3.1 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
3.3.2 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.
3.3.3 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.
3.3.4 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 when a communication failure on the PROFIBUS
interface is detected. If the parameter is set to "No xfer on fail", the output image
will continue to be transferred. If the parameter is set to "xfer on comm fail", the
output image will not be transferred and the last values will be retained.
