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.
