1794-IE8H and -OE8H
Extended Configuration
Data Table The FLEX I/O HART modules are addressed by using an MSG or CIO
instruction. When using one of these instructions, configure it to the
following.
• Class: 0x7D
• Instance:
Slot number (range from 1 to 8 with 1 being the I/O
module closest to the adapter
• Attribute: 0x66
• Service: 0x0E for a get attribute single or 0x10 for a set attribute single
Also, configure the communication path to the target I/O module.
For a set attribute single, configure two words as defined in the Extended
Configuration Data Table to be sent to the I/O module.
For a get attribute single, two words configured as defined in the Extended
Configuration Data Table will be returned from the instruction.
