Online parameterization of the device
Devices can also be parameterized online. In doing so, you can also select whether only individual parameters
(single) or all parameters (all) of a group are read from the device (upload) or are loaded into the device (download).
It is also possible to transfer individual parameters or all parameters of a group cyclically in monitor mode. This
may be helpful particularly for start-up purposes.
12.13. Display of the status LEDs in the event of a bus
error
Bus errors are also indicated on the central three-colored status display, see Chapter "17.2. Blinking
pattern & fault signaling"!
The device status LED ("modules")
and the bus status LED ("network") are
located on the electronics module
Function tests for both status LEDs after power has been switched on (connection of the network cable):
Status LED
Colors of the LED
Function test
"Modules"
green
• 250 ms ON (green)
"Network"
green / red
• 250 ms ON (green)
• 250 ms ON (red)
Then another function test is run during which the LEDs light up briefly.
When the test is complete, the status LEDs indicate the device states which are described in the following tables.
