17.1 Configuration diagrams
The use of the configuration diagrams is explained in subsection 3.2.4.
17.1.1 Terminal markings
The designations of the signal inputs and outputs and of the assigned connection
terminals are structured as follows:
Example
Explanation
N.X3
N = controller RMH760B
X3 = universal input
A9(2).Y1 A9 = type of extension module
(2) = 2nd extension module of same type
Y1 = analog output DC 0…10 V
N.Q5
N = controller RMH760B
Q5 = relay output
17.1.2 Code letters
Physical inputs and outputs are identified by uppercase code letters:
