Synchronous Data Refresh Setting
1. Setting of Input Area Start Position
2. Registration of Synchronous Units
3. Setting of Output Sizes and Input Sizes
Data exchange between the CPU and Synchronous Units uses Synchronous Data Refresh areas.
Synchronous Data Refresh areas are allocated to the I/O areas 1,200 to 1,295 words in the CPU.
You can set the CPU and Synchronous Units, respectively, to set the types of data which you
exchange between the CPU and the allocated areas of each unit.

First, set the allocation of the Synchronous Data Refresh areas on the PLC Settings of the CPU.
On the PLC Settings, set the start address of [Input] of synchronous data refresh from the
[Synchronous Data Refresh Area Allocation] setting. This divides the Synchronous Data
Refresh area into the output (from CPU to PCU) area and the input (from PCU to CPU) area.
Set the output sizes and input sizes of synchronous data refresh for registered Synchronous
Units. This sequentially allocates the output area of the set size, from the beginning of the
Synchronous Data Refresh area, and the input area from the input area start address,
respectively.
