9.8 Frequently Asked Questions
9.8.1 How fast do the "Backplane Data Exchange" commands run?
The "Backplane Data Exchange" commands will execute one at a time during the
I/O service interval of the PLC. What this means is that if you had a list of 10
commands at the end of every PLC scan one command would execute. This
would mean that it would take 10 PLC scans to execute the 10 commands
contained within the "Backplane Data Exchange" section of the configuration file.
9.8.2 What is the maximum number of words I can transfer with a
"Backplane Data Exchange" command?
For command types 1 & 2 you may move up to 130 words with each command.
Function 3 is somewhat different in that it provides only 64 words of data
movement BUT because it is intended to solve very specialized operations its
size must be restricted.
9.8.3 How do I configure the module?
The ProTalk requires a simple text based configuration generated by ProSoft
Configuration Builder software to make it operational. For a really quick tutorial
on the modules communications with the PLC you should review Module
Configuration (page 49). For more in-depth information, refer to Backplane Data
Exchange (page 55).
9.8.4 What kind of data transfer rates can I expect between the PLC
and the module?
Data transfer rates between the PLC and the module depend on a number of
variables, among them the number of words being transferred per command, the
amount of other network traffic at the time data is being transferred, and overall
processor scan times.
9.8.5 Is a .MDC available for configuration of the Module?
Yes. The included DVD will have a version for both Concept 2.5 and 2.6.
9.8.6 Does the module work in a remote rack?
The module is designed to be located in the chassis with the PLC and will not
operate in a remote chassis.
9.8.7 Can I use the module in a hot backup system?
The PTQ-104S Rev 1 manual does not support Hot Standby, v2 does. Refer to
the PTQ-104S Rev 2 user manual for additional details on the HSBY support
added for the Rev 2 modules.
