Note1) Although it has adequate tolerance to noise, it is recommendable to make the user program to
execute retransmission (in order to improve reliability of the communication when a
communication error occurs due to excessive noises or when a receiver equipment cannot
receive data temporarily).
Note2) The number of units of the PC(PLC) link with RS232C is two.
