DeviceNet I/O Assemblies
The changing of the I/O assemblies from the default to other assemblies using CHStudio is
performed in a graphical user environment. When using a generic DeviceNet Management
tool that accepts EDS files, the EDS file will aid in simply choosing the I/O assemblies that are
allowed and available.
Table 36: Allowable DeviceNet I/O Assemblies
*Indicates the default
For users that have a generic DeviceNet Management tool that does not accept EDS files,
follow the simple example below to aid in changing I/O assemblies using explicit messaging.
To read what the current Input assembly is, perform an explicit message of the following:
Table 37: Reading Current Input Assembly
To set the Input assembly, perform an explicit message of the following:
Table 38: Setting Input Assembly
To read what the current Output assembly is, perform an explicit message of the following:
Table 39: Reading Current Output Assembly
To set the Output assembly, perform an explicit message of the following:
