8.1 Serial Port Protocol Error/Status Data
The second and most thorough troubleshooting method for debugging the
operation of the DFCM driver (and the module in general) is the powerful Debug
port on the module which provides much more complete access to the internal
operation and status of the module. Accessing the Debug capabilities of the
module is accomplished easily by connecting a PC to the Debug port and loading
a terminal program such as ProSoft Configuration Builder or HyperTerminal.
8.1.1 Viewing Error and Status Data
The following topics describe the register addresses that contain protocol error
and status data. Viewing the contents of each register is accomplished using the
Database View option. The use of this option and its associated features are
described in detail in the ProLinx Reference Guide.
8.1.2 DF1 Error and Status Data Area Addresses
DF1 error and status data are stored in registers based on the DF1 port
configuration. Starting register addresses are shown in the following table.
DF1 Port Starting Address
0 6300
1 6700
2 7100
3 7500
Note: None of the addresses are available in the DF1 address range. In order to view them, the
data must be moved using the Data Map section of the configuration file. Refer to Moving Data
(page 70) for an example of how to move data to the DF1 address range.
