2.5.1 P1 and P2 Override File Mappings
This feature allows a write command to be re-directed to the module's ReadData
area. If the DF1 master has a fixed address to write to, the module's WriteData
area with the delivered data would be overwritten on the next scan. This feature
requires that the port be configured as a slave.
Note: A Slave ID setting of 255 will respond to all commands sent on the network. If this setting is
used in a multipoint network, only writes should be used on the network from the DF1 master.
2.6 Changing parameters during operation
A copy of the module's configuration data is mapped in the module's database as
displayed in the following table. These values are initialized when the module first
receives its configuration from the configuration file.
