Parameterization/startup record
When setting up a connection, the startup parameter record (record 1) is sent from the IO
controller to the ATD430W as specified in the GSD file (see Table 6-28 GSD files
(Page 150)). Only the cycle time parameter is visible in the configuration tool.
The structure of the 8-bytes-long startup parameter record 1 is described below (for
informational purposes only):
