6.5.25 Output hardware
Depending on the hardware modules used (see CG number), it may be possible to change the
output options on terminals A, B, C or D in the menus C3.1.x. For example: A pulse output to a
frequency output or a status output to a control input.
The available options are determined by the hardware module used. It is not possible to change
the type of output, e.g. from active to passive or to NAMUR.
6.6 Status messages and diagnostic information
The diagnostic messages are displayed in accordance with NAMUR standard NE 107. The error
messages for the device are divided into status groups, each with one status signal. There are 16
status groups with fixed status signals and 8 groups with variable status signals. To facilitate
identification of the problem source, the status groups are then divided into the groups: Sensor,
Electronics, Configuration and Process.
The variable status signal can be changed in menu C1.5.7...C1.5.14. Changing the status signal to
"Information" switches off the message.
Each status message (= status signal) has a specific symbol, determined by NAMUR, which is
displayed with the message. The length of each message is limited to one line.
All status messages are saved in the status log (menu B3.1). Use the ↑ and ↓ keys to navigate
through this list. Use the ^ key to exit the list.
The status screen shows the status groups of all errors that have occurred since the last time
the status screen was opened. All errors that are not current disappear after 2 seconds. They
are shown in the list in brackets.
INFORMATION!
As status message always the name of the relevant status group and the status signal (F/S/M/C)
is displayed.
