(3) Ident Number
Refer to section 4.5 for explanation of Ident
Number.
(a) Confirmation by the name plate
Device specific Ident Number and Profile Ident
number is marked on the name plate. Profile
Ident Number is inside [ ]. (9700 to 02(9720),
9740 to 42(9742))
Refer to Figure 4.3.
(b) Confirmation from integral indicator (When the
integral indicator code “E”)
Please refer to section 4.2.
(c) Confirmation by parameter
Ident Number can be confirmed from Physical
Block parameter Ident Number (IDENT_
NUMBER).
• Procedure to call up the display
DTM Physical Block → Identification → ID No.
EDD Identification → Device → ID No.
