Additional Information
• Leftmost digits are stored in the lower memory addresses. Treat the data in the lower memory
address as the leftmost digits when programming.
• Be sure that the data is read at least once every 125 ms to allow for the CPU Unit's cycle time
and communications time. Correct data may not be obtained if the read cycle is greater than
125 ms.

Programming Example

The following programming example shows how to use 2-decimal-place Mode for the following PLC
configuration.
CPU Unit
Inputs
CIO 000
CIO 001
Outputs
CIO 100
CIO 101
In this example, 100 times the temperature data for temperature input 0 (input to CIO 002) is stored
in binary form in D100 to D102.
