7.2.15 [BFM#176 to 207] Remote register RWw
These remote register (RWw) buffer memory addresses store the word information received from the
master station.
Read these buffer memory addresses using the FROM instruction (or direct buffer memory specification)
to use the stored word information.
Caution
• When the TO instruction (or direct buffer memory specification) is executed, 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
