16.1 Configuration diagrams
Use of the configuration diagrams is explained in subsection 3.3.5 „Use of configuration
diagrams“
16.1.1 Terminal markings
The designations of the signal inputs and outputs and of the assigned connection
terminals are structured according to the following pattern:
Example Explanation
N.X3 N = controller RMK770
X3 = universal input
N.D1 N = controller RMK770
D1 = digital input
A9(2).Y1 A9 = type of extension module
(2) = 2nd
extension module of the same type
Y1 = analog output DC 0…10 V
N.Q7 N = controller RMK770
Q7 = relay output
16.1.2 Code letters
Physical inputs and outputs are marked with uppercase letters:
