Synchronous Data Refresh Section 5-4
Synchronous Data
Note (1) Synchronous data for Coordinator Modules is fixed to general-purpose
(ladder execution results) data.
(2) If there is no synchronous data to be sent, select no data for Select Syn-
chronous Data in the System Setup to shorten the synchronous data
transfer time.
(3) Auxiliary Area data is transferred when input and output refresh method
is set to Immediate refresh and the synchronous data is set to an analog
input or analog output value in the System Setup.
