(e) Setting example
When two auto refresh setting ranges are configured for a system comprising of a
Universal model QCPU (CPU No.1) and a C Controller module (CPU No.2), the
send and receive areas in each auto refresh area are as illustrated below.
If auto refresh settings in Figure 13.19 are configured for each CPU, the auto
refresh areas of the Universal model QCPU (CPU No.1) and C Controller module
are allocated as shown in Figure 13.20.
