Write device data to buffer memory: TO
■Usable data
: Usable
■Description, data type of result
• (n) words of data from the device specified with (S) are written to the address specified with (D2) and after of the buffer
memory in the specified with (D1).
Writing device data can be performed with the module access device (U\G).
(Example)
Writing 2 words from #0 to buffer memory address 0H of intelligent function module (start I/O number: 010H).
Refer to the following for details of module access device.
MELSEC iQ-R Motion Controller Programming Manual (Common)
• First I/O No. of the module set by [System Parameter] [I/O Assignment Setting] in GX Works3 is specified by (D1). (D1)
sets 20H by the system configuration when a TO instruction is executed in the D/A conversion module (R64DA).
