6.1.3

H/EH series network address

At H/EH series network system shown in Figure 6.3, you must specify the CPU address according to the
LUMP address rule as below.
CPU

Figure 6.3
Network address configuration is below.
L: Loop No. (CPU link number)
U: Unit No. (CPU link station number)
M: Module No.
P: Port No.
(1) Loop No.(L)
Item
CPU LINK loop1
CPU LINK loop2
Without CPU LINK
(Note) When loop No. is FFH, Unit No. must be FFH. Even the reverse is similar.
(3) Module No. (M)
Always "00H"
Table 6.2 shows the example of network address setting in Figure 6.3.
