L: The Last Block Mark is always set to one in the last Data Block of the
messages, else it is reset to 0.
Function Code: The function code is a 7 bit field that defines the purpose of the
message. The RTU generally echoes the function code sent by the Master,
except when the RTU cannot perform the requested function due to an error,
timeout, bad parameter, or some other condition that is not logical to the RTU.
Length: The Length is a 7 bit field specifying the number of bytes in the Data
Field. If it is 0, then the Data Block does not contain a Data Field.
Data Field: The Data Field contain Function Code specific operational
information (that is, point numbers, parameters, etc.)
8.6.6 RTU CRC
The CRC code included in the message is the standard CRC16 based on the
polynomial. For a correctly received message the remainder will be zero after
passing the entire message, including the CRC word, through the CRC
computation. The bits of each message byte are passed through the CRC
computation in the same order that they are transmitted, least significant bit first.
8.7 Frequently Asked Questions
8.7.1 How do I configure the module?
The ProTalk requires a simple text based configuration file to make it operational.
For a really quick tutorial on the modules communications with the PLC you
should review the [QUICK START GUIDE] or for more in depth information the
chapter on "Backplane Data Exchange" should answer most questions.
8.7.2 What software package is required for my Ladder
Logic?
The design of the module should be software independent and for many
installations minimal or possibly no ladder will be required. The section on
"Backplane Data Exchange" offers to samples to help in the few instances where
ladder is required.
8.7.3 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 amount of other network traffic at the time data is
being transferred, and overall processor scan times.
8.7.4 Is a .MDC available for configuration of the Module?
Yes. The CDROM that ships with the module should have a version for both
Concept 2.5 and 2.6 in the ProTalk directory.
