3.1 [Modbus Plus Configuration]
The [Modbus Plus Configuration] section of the CFG file sets general
characteristics of the Modbus Plus port.
Example
Parameter Description
The following section lists the parameters.
3.1.1 Local Node Address
1 to 64
This value defines the Modbus Plus Node Address for the module. A valid node
address must be entered for the module to operate, and the address must be
unique on the network. Valid values are between 1 and 64, inclusive.
3.1.2 Global Output File Length
0 to 32
This value defines the number of Global Output words to be placed on the
Modbus Plus network. If the value is set to 0, no global output data will be placed
on the network. Values of 1 to 32 represent the number of words to be used by
the module. This data must be transferred from the processor to the module.
Important: ProLinx Modbus Plus modules use memory addresses 3960 to 3991. If you plan to use
Global Output Data, you must not use this memory area for normal data transfer, otherwise data
may be overwritten and unpredictable results may occur.
