Data Processing Timing
Example 3 Timing Hold:
No. of Mean Value Processings: 2
Input Sampling Speed:
Data Read
When a ladder program is used to automatically read the data to be input, the data is sampled in synchronization
with timing input. Therefore, the CPU used with the Unit must read the data in synchronization with the sampling
timing.
Timing Input Connected in Parallel
The timing signal can connect with the TIMING/GATE terminal and the input word of the CPU in parallel as shown
in the following illustration to synchronize the operation of the CPU and the sampling timing of the Unit.
The Unit requires time to process input and to set data to its input word corresponding to the input. The actual data
reading timing must be later than the moment timing input to the Unit is ON. The input process time varies with the
timing hold currently selected. The following is the input process time with its timing hold set to sampling hold.
