The communication format determines the data structure the I/O module
uses, as well as the type of connection made to the module and the controller
ownership of the module. Many I/O modules support different formats. Each
format supports a different data structure.
You select the communications format when you configure the I/O module.
The default communication format for an I/O module is for a direct

property damage, or economic loss.
