7.2.16 [BFM#304 to 335] Remote register RWr
Using these remote register (RWr) buffer memory addresses, the TO instruction (or direct buffer memory
specification) sets the word information to be sent to the master station.
Caution
• When the TO instruction (or direct buffer memory specification) is executed for writing to an area without
assigned link points, writing is invalid. When the FROM instruction (or direct buffer memory specification) is
executed for reading from an area without assigned link points, the reading operation results in "0" being
read.
: Applicable -: With no allocation
