5.3.3 Defining Data to be Retrieved from the PTQ Database.
Your application may need to retrieve 105 words of data from other devices on
the network. These devices have either sent you the data if you are a server, or
you have obtained it for your use if you happen to be a master in your
application. Assuming that the data resides in registers 207 to 312 within the
PTQ modules memory and you wish to place this information in addresses
400208 to 400313 within the Quantum you could use Command Function 2 to
transfer the information.
Because the total amount of data does not exceed 130 words in length, a single
command can be used to transfer the data. This additional entry will be added to
our [Backplane Data Exchange] section and it would look like the third command
below:
The third command states:
Field Value Meaning
Command Type 2 The type of operation to perform
2 = Write data from the PTQ to the Quantum
PTQ Address 207 The destination address within the PTQ
Point Type 4 The range of registers to read from the Quantum
4 = 4:x style register
Quantum Address 208 The starting address of the data within the Quantum
This would be Point Type + Quantum Address
Example: 40000 + 207 = 40207
Word Count 105 The number of registers to transfer
