Areas and First Address of Linked Data

Two areas are used in PLC memory by the E5@C-T, an upload area and a download area. The upload
area is used to monitor the process value, status, and other information from the E5@C-T. The down-
load area is used to write the fixed SP, segment SPs, segment times, alarm values, and other values to
the E5@C-T.
