NOTICE!
Risk of malfunctions in the plant!
The outputs may switch on for a period of 10 to 50 µs if the process supply
voltage UP/ZP is switched on.
This must be considered in the planning of the application.
NOTICE!
Risk of damaging the I/O Module!
The outputs are not protected against short circuits and overload.
– Never short-circuit or overload the outputs.
– Never connect the outputs to other voltages.
– Use an external 3 A fast-protection fuse for the outputs.
The module provides several diagnosis functions (see Diagnosis Ä Chapter 1.5.1.1.7.6 “Diag-
nosis” on page 227).
The meaning of the LEDs is described in the section State LEDs
Ä Chapter 1.5.1.1.7.7 “State
LEDs” on page 228.
I/O Configuration
The module itself does not store configuration data. It receives its parameterization data from
the master device of the I/O bus (CPU or bus module) during power-up of the system.
Hence, replacing I/O modules is possible without any re-parameterization via software.
If the external power supply voltage via UP/ZP terminals fails, the I/O module
loses its configuration data. The whole station has to be switched off and on
again to re-configure the module.
