[BFM #8 to #23 (remote register RWr0 to RWrF)]
•
To each buffer memory No., a remote register No. RWr0 to RWrF is assigned.
The information to be written to the master unit should be preliminarily transferred from the FX PC to this
buffer memory.
The FX PC can write the contents of word devices and bit devices of the FX PC using TO instructions.
•
In the FX
2N
-32CCL, the remote register point range (RWr0 to RWrF) varies depending on the selected
number of stations (1 to 4). (
