NOTICE!
Risk of damaging the PLC modules!
The PLC modules must not be removed while the plant is connected to a power
supply.
Make sure that all voltage sources (supply and process voltage) are switched
off before you
– connect or disconnect any signal or terminal block
– remove or replace a module.
NOTICE!
Risk of damaging the PLC modules!
Overvoltages and short circuits might damage the PLC modules.
– Make sure that all voltage sources (supply and process voltage) are
switched off before you begin with operations at the system.
– Never connect any voltages or signals to reserved terminals (marked with
---). Reserved terminals may carry internal voltages.
The module provides several diagnosis functions

2-wires input 3-wires input
With 2-wires connection, the resistance of the connection wires influences the
accuracy of the measured value. Use 3-wires connection to achieve the guaran-
teed measuring accuracy.
The meaning of the LEDs is described in the Displays section

LEDs” on page 412.
I/O Configuration
The analog input module AI562 does not store configuration data itself.
