Expansion of Basic System with External I/Os S5-95F
Example: Connection of Two-Channel Sensors (Type C)
Insert one module into slot n of subunit A and the other module into slot n+1 of subunit B, with
n being an even number between 0 and 30 (see section 6.2).
Connect the 24 V DC supply voltage to terminals 1 and 2.
Wire the inputs with the sensors (as shown in Figure 5-13).
Parameterize the inputs in DB1.
