6.1.3 H series network address
At H series network system shown in figure 6.1.3.1, you must set CPU module address to specify the
appointed CPU module.
Network address configuration is below.
(1) Loop No.(L)
CPU LINK loop1
CPU LINK loop2
CPU LINK Non
(Note) When loop No. is FFH, Unit No. must be FFH. Even the reverse is similar.
(3) Module No. (M)
Always "00H"
Table 6.1.3.2 shows the example of network address setting which CPU access each CPU, Figure 6.1.3.1
