● Efficient Data Sending/Receiving
Inter-FCN/FCJ communication processing is performed for each function block for
sending/receiving. Thus, for send/receiving the same data size, reducing the
number of function blocks for sending/receiving increases communication efficiency.
Example: Sending 10 data using unconfirmed communication
USEND_1V x 10
USEND_5V x 2
USEND_10V x 1
Any of the above ways can be used. However, using USEND_1V requires 10
send processing while using USEND_10 requires only one send processing,
thus reducing the total time required for send processing.
Moreover, using array data allows more data to be transmitted each time.
Example: Sending 100 REAL-type data using unconfirmed communication
Sending one data each time : USEND_10V x 10
Sending data collectively using AR_REAL61 : USEND_10V x 1
Again, any of the above ways can be used.
Sending one data each time requires ten USEND_1Vs.
AR_REAL61 is a system-defined array type for storing 61 REAL-type values.
Consolidating the 100 data in this array type requires two variables, and one
USEND_10V for sending.
