5.2.3 Error Offset
0 to 3980, or -1 to disable
This parameter specifies the database location where to write status data.
5.2.4 Initialize Output Data
Yes or No
This parameter determines if the output data for the module should be initialized
with values from the processor. If the value is set to No (0), the output data will
be initialized to 0. If the value is set to Yes (1), the data will be initialized with
data from the processor. Use of this option requires associated ladder logic to
pass the data from the processor to the module.
5.3 Backplane Data Exchange
Before modifying the [Backplane Data Exchange] section of the configuration file,
you must understand some important concepts. The following topics describe
these concepts.
If you have used the parameters defined in the [Module] section, you have
created the following memory map. We will use this map to explain how data
transfer works between the processor and the ProTalk module.
PTQ Memory Address Application Memory Address
0 = 0
10 = 10
20 = 20
30 = 30
40 = 40
50 = 50
… …
206 = 206
207 = 207
… = …
312 = 312
A thorough understanding of the information contained in this section is required
for successful implementation of the module in a user application.
5.3.1 Data Transfer
The module uses a concept referred to as "Command Functions". The command
functions reside in the [Backplane Data Exchange] section of the configuration
file. This method of data transfer is probably different from other methods you
might have used, but does offer some unique advantages:
 The amount of ladder logic required will be substantially reduced; in fact in
many applications no ladder logic will be required.
 The module may be placed in any position in the chassis containing the PLC
and will operate with no modifications.
