Example of connection designation for an input:

x20 (6) I 0.5

1)

Input 5 (5th bit); 0 to 7 possible

Address of input byte (byte 0);

0 to 255 possible

I = Input

6th group (not speci- fied in the address)

Data Memory and S5 Bus Control

g	=	Green LED (status indicator)
F+/F-	=	Enable input (jumper in front connector)

1)Changeover of enable mode with jumper X20:

Jumper inserted = Enable input active (factory setting) Jumper open = Enable input inactive.

2) The terminal is not connected internally. When this terminal is connected to input voltages, the clearances in air and leakage paths remain adequate to UL, CSA and VDE.
