(3) Processing speed
The processing speed of the intelligent function module device is as follows:
• The processing speed of writing or reading using the intelligent function module device is slightly higher
compared with the case of using the FROM or TO instruction.
Example
• When reading from the buffer memory of an intelligent function module and another processing with one
instruction, totalize the processing speed of the FROM or TO instruction and the other instruction.
Example
Instead of using the intelligent function module device in the sequence program twice or more to write or read buffer memory
data, using the FROM or TO instruction once in one place can increase the processing speed.
Remark
1. For buffer memory addresses and applications, refer to the manual for each intelligent function module/special
function module.
2. For the FROM and TO instructions, refer to the following.

"MOV U2\G11 D0"
