Overview
DESCRIPTION Data from the fieldbus (DeviceNet) and the sub network (Modbus) is stored in an internal
memory buffer. This is a easy method for data exchange where the fieldbus control
system simply reads and writes data to pre-defined memory locations, and the serial sub
network also use the same internal memory buffer to read and write data.
Refer to Figure 3-1: Data exchange overview on page 3–2 for additional details.
