Determining the D D i i r r e e c c t t NET Address
D
Addressing the memory types for DirectNET slaves is very easy. Use the ordinary native
230
address of the slave device itself. To access a slave PLC's memory address V2000 via
240
DirectNET, for example, the network master will request V2000 from the slave.
