7.9 I/O POLLING CONFIGURATION EXAMPLE
Example Using the Keypad to configure the data produced and consumed by a
polled Master/Slave connection for AV300.
The keypad interface can be used to configure the content of the produced and
consumed data in the Master/Slave connection set. Only16-bit drive parameters
can be entered as polled I/O parameters. The instruction manual parameter list
identifies the eligible parameters with an R or W in the Opt2-A/PDC column.
The polled I/O connection size is four words (8 bytes) produced and four
words (8 bytes) consumed
1.
Enter a value of 8192 in the Par.Index Offset parameter.
The drive parameter index is equal to the drive parameter number plus 2000h
(8192). Par.Index Offset adds the standard offset to parameter numbers assigned
to the polled I/O connection such that a parameter number can be directly
entered as a parameter index. The offset value is stored in volatile memory
and is not retained when drive power is lost.
2.
Enter drive parameter numbers for the polled I/O connection. Following
is an example of polled data configuration;
