Module Configuration 48TPTQ-104S Rev 1 ♦ 47TQuantum Platform
12TUser Manual 46TIEC 60870-5-104 Server for Quantum
This example shows an application that reads 207 words from the Quantum to
the module and writes 105 words from the module to the Quantum.
The [Backplane Data Exchange] section is a series of messages that instruct the
module how to transfer data to/from the Quantum. What is missing from the
message is the ability to schedule its execution. This ability is normally left to the
programmer in the PLC environment. However, in the PTQ module this is not
included so that the commands may run as fast as possible to maintain the
synchronization of the two databases. One command from the list will execute
during each I/O service interval at the end of the PLC ladder logic evaluation. So
as an example if your configuration contains 10 "Backplane Data Exchange"
commands it will require 10 PLC scans to process the entire list.
This section may contain up to 100 individual commands used in any
combination to transfer data to/from the Quantum. The following topics provide
information on the use of the commands as well as simple examples.
5.4.1 Set Up Command Function 1 (Read data from the Quantum)
This section provides information on how to read data from the Quantum into the
module.
Command Function 1 is designed to transfer data from the Quantum to the
module on a continuous basis. The command(s) required to transfer your
application data should be entered in the [BACKPLANE DATA EXCHANGE]
section of your configuration file as required.
This command takes the following parameters:
 Command type: 1 (Read data from the Quantum)
 PTQ Database Address: The destination for the data retrieved from the
Quantum.
 Point Type: The type of register within the Quantum (0:x = 0, 1:x = 1 3:x = 3
or 4:x = 4)
 Quantum Address: The source of the data within the Quantum. The address
is expressed without the use of the register range, for example 400001 would
be entered as 1 (400001 - 400000 = 1 or 40001 - 40000 = 1)
 Word Count: The number of words to copy. The length of this copy may be
any length of 1 to 130 inclusive. If your application requires the movement of
additional data you may enter additional commands.
