Easy Maintenance
6.6.1
Overview
Easy Maintenance means the support for adding and removing
ricos
FLEX system modules during
operation without having to restart the system. There are the following behaviors:
•
As soon as a module is removed, the
ricos
FLEX BC MODBUS detects this and automatically
switches to
Maintenance
state. In this state, all input and output data become invalid. By
re-plugging the module or a compatible module, the Maintenance state is left again.
•
As soon as a module is added to the existing modules, the
ricos
FLEX BC MODBUS detects
this and automatically refreshes its reference configuration.
Please always replace only
one
module in your configuration.

Examples
Module is removed
If a module is removed, the
ricos
FLEX BC MODBUS behaves as follows:
1.
The
ricos
FLEX BC MODBUS switches automatically to
Maintenance
state.
2.
The process data communication is ended.
→
The SF LED remains off.
The MT LED lights up.
The SB LED turns off.
The message 'Missing Module (ID
...
)' is shown on the website.
Compatible module is added again
If a compatible module is inserted into the slot of a previously removed module during an active bus
connection, the
ricos
FLEX BC MODBUS behaves as follows:
1.
The
ricos
FLEX backplane bus is refreshed.
2.
The process data communication is continued after the bus scan.
→
The SF LED remains off.
The MT LED turns off.
The SB LED lights up.
After updating the website, the correct module configuration is shown again instead of
'Missing Module (ID ...)'.
Incompatible module is added again
If an incompatible module is inserted into the slot of a previously removed module, the
ricos
FLEX
BC MODBUS behaves as follows:
1.
The
ricos
FLEX BC MODBUS remains in
Maintenance
state.
2.
The process data communication remains interrupted.
→
The SF-LED lights up.
The SB LED blinks.
The MF LED of the wrong module blinks.
The message 'Wrong Module ...' is shown on the website.
