FUNCTIONS
(3) Functions
The serial communication function allows the MC protocol commands in Table6.54 to
be executed.
Refer to the following manual for details of the MC protocol.
Q-Compatible MELSEC Communication Protocol Reference Manual
* 1 : When performing online change of the CPU module, set online change setting to "Enable".
* 2 : Set the number of processing points within the range of the following expression.
(Number of word access points) 12 + (number of double word access points) 14 960
•One point of a bit device corresponds to 16 bits for word access or to 32 bits for double word
access.
•One point of a word device corresponds to one word for word access or to two words for double
word access.
