RSLogix 500 Parameter Read/Write Examples
In this example, a read and a write of PowerFlex 40 drive Parameter 78
- [Jog Frequency] is being done.
The RSLogix 500 Message Configuration screen example to read a
parameter is shown in
Figure 5.3 . It is assumed that the 1769-SM2
module occupies slot 1 and is operated in Single mode, and that the drive
is connected to CH1.
See Table 5.A for descriptions of the message configuration data.

The response data for the message is stored at Data Table Address N7:3.
The Size in Bytes of the response data is 2 bytes because the data size for
PowerFlex 40 drive Parameter 78 - [Jog Frequency] is 2 bytes (1
word). No Data Table Address is specified for the request data, since the
Read Parameter service has no request data.
