Processing
● The instruction requests the starting of the EtherNet/IP cyclic communication according to
the start request node number table that is stored in the area that starts from [S].
● For [n], specify the maximum node number among the nodes to which the start of the
EtherNet/IP cyclic communication is requested.
● The execution result is stored in [D].
■
Operand [S] setting
● Specify the starting address of the device area that stores the start request node number
table.
● Use a user program to create the start request node number table. Turn ON the bits (that is,
set the bits to 1) that correspond to the node numbers to which the start request is made.
(Example) When [S] is set to WR100 and the start request is made to nodes number 1 and 2
