7.8.2
Writing 1-/2-word data to intelligent function module (TO(P),DTO(P))
TO(P),DTO(P)
Function
TO
Writes the data stored in n3 points starting from the device designated by into the area
starting from buffer memory address designated by n2 of the intelligent function module
designated by n1.
When a constant is designated to , writes the same data (value designated to ) to the area
of n3 points starting from the specified buffer memory. ( can be designated in the following
range: -32768 to 32767 or 0
H to FFFFH.)
n1 : Head I/O number of an intelligent function module (BIN 16 bits)
n2 : Head address of the area where data is written (BIN 16 bits)
: Data to be written or head number of the devices where the data to be written is stored (BIN 16/32 bits)
n3 : Number of data blocks to be written (BIN 16 bits)
