Figure 71: Controller Tags for I/O Access
We can directly interact with these tags in order to control and monitor the drive. In Figure 71, we can see that the first
Similarly, we can see that the second
(ASD_G9ETH:O.Data[1]) has been set to a decimal value of 1234. Once again referring back to Figure 37, we can see that the second element of the consumed register configuration references register 1008, which is the drive’s option board frequency command register. A value of 1234, therefore, equates to a frequency command of 12.34Hz.
The input data from the drive shows similar expected results. Values of 0x6404 and 1234 corresponding to registers 1402 (inverter status 1) and 1401 (output frequency), respectively, are consistent with the drive running at the parameters commanded by the output tag.
13.2.5 Explicit Messaging Tag Reference
When class 3 (explicit messaging) connections are used, register contents are read from and written to the interface card via EtherNet/IP by reference to “tag names”. Tags are read via the EtherNet/IP “data table read” service, and tags
