Diagnostics, Missing supply voltage L+
Enabling of the diagnostics for missing or insufficient supply voltage L+.
IO redundancy
You can configure two identical modules redundantly. To do so, plug both modules into a
redundant terminal block side by side. You can find additional information on mounting
modules in an IO redundancy configuration in the ET 200SP HA System Manual, section
"Installing", "Installing terminal block".
In IO redundancy mode, the left module is the master and the right module the slave.
The two redundant modules measure the process simultaneously and independently. The two
redundant modules form diagnostics, interrupts and process values.
Diagnostic short circuit
Enabling diagnostics message when a short circuit occurs between the leads of the encoder.
Short circuit diagnostics can be used in the following settings of the encoder:
● NAMUR sensor
● NAMUR change-over contact
Diagnostics, Wire break
Enable of the diagnostics for when the module has no power or insufficient power at the
corresponding configured input.
You can use the wire break diagnostics with the following setting of the encoder:
● NAMUR sensor
● Single contact with 10 kΩ
● NAMUR change-over contact
● Change-over contact with 10 kΩ
Diagnostic change-over contact error
The diagnostics alarm is enabled when a change-over error occurs.
The diagnostics change-over contact error you can use with the following adjustment of the
encoder:
● NAMUR change-over contact
● Change-over contact, unconnected
● Change-over contact with 10 kΩ
Change-over contact errors can be detected only with errors detected input signals.
