Example 1
In the example shown in Figure 4, Input 1 (connected to module M1) is tested with the M1-T1
test signal. During wiring, the 24Vdc is connected to input 1 instead of the M1-T1 test signal.
-
The I/O index and Diagnostic code fields assume the following values: 1 - 20 to
indicate the diagnostics on input 1 of module M1 (Connection error).
Figure 4
Example 2
In this example, the I/O index corresponds to the logical block and not to the physical terminal
on module M1.
In Figure 5 for example, the two-hand element connected to the Input 1 and Input 2 physical
terminals corresponds to I/O index No. 1 and the emergency stop connected to the Input 3 and
Input 4 terminals corresponds to I/O index No. 2.
