I/O Device Address Format

When you add a device to the I/O configuration, the
Studio 5000 Logix Designer®
 application creates controller-scoped tags for the device.
I/O information is presented as a set of tags. Each tag uses a structure of data, depending on the type and features of the I/O device. The name of a tag is based on the name of the device.
A safety I/O device address follows this example:
devicename:Type.Member
