Replacing an Active module with failure
If the Active module fails, the Backup module takes over as LAS (Link Active Scheduler).
Here follows the procedure for the case the Active module must be replaced.
1 - With the H1 connector disconnected, insert the new module in the backplane.
2 - Update the firmware in the new module, if necessary. Perform a
Factory Init
in the new module in
order to grant the default state.
3 - IMPORTANT- before connecting the H1 connector to the new module, the user must follow the
steps below:
4 - Open the desired configuration in the
SYSCON
and put it in
On-line mode
. Right-click the
bridge
icon and with the option
Attributes
choose the module to be configured as
Active
in the field
Device Id
.
5 - Even in the
bridge
icon, right-click the field
FB VFD
and then click
Block List
. A new window will
be opened showing all the blocks pre-instantiated in the module. Then, in this window, right-click
the
transducer
performing an
Assign Tag
with the
tag
that is predicted for the
Active
in the
configuration. Close the
Block List
window. In the main menu go to
Export
and click
Tags
.
6 – Right-click the
transducer
icon in the
bridge
and choose
On Line Characterization
. Configure the
FUNCTION_IDS parameter as
Passive
.
7 – And then, connect the H1 connector to the new module, and after that set the FUNCTION_IDS
parameter as
Active Not Link Master
.
8 – Even in the transducer, set the parameter SYSTEM_OPERATION as
Redundant
. Wait until the
Live Lists
of all channels are completed.
9 - For each one of the channels used in the configuration right-click the
Fieldbus
icon and choose
the option
Download Schedule
.
10 – Change the parameter FUNCTION_IDS from
Active Not Link Master
to
Active
.
Replacing a Backup module with failure
If the Backup module fails the
Active
module remains as LAS (Link Active Scheduler).
The procedure for the case the
Backup
module must be replaced is the following:
1 - With the H1 connector disconnected, insert the new module in the backplane.
2 - Update the firmware in the new module, if necessary. Perform a
Factory Init
in the new module in
order to grant the default state.
3 - IMPORTANT – before connecting the H1 connector, the user must follow the steps below:
4 – Right-click the
bridge
icon and with the option
Attributes
, choose the module to be configured as
Backup
in the
Device Id
option,
5 – In the configuration, change, for a while, the
transducer
tag (the
Backup
module must have a
different tag in comparison with the
Active
). In the Syscon main menu, go to
Export
and click on
Tags
.
6 – Even in the
bridge
icon, right-click in
FB VFD
, and then click on
Block List
. A new window will be
opened showing the pre instantiated blocks in the module. So, in this window, right-click in the
transducer
to do an
Assign Tag
with the tag that is the
Backup
in the configuration. Close the
Block List
window..
7 – Right-click in the
bridge
icon of the
transducer
and choose
On Line Characterization
. Configure
the parameter FUNCTION_IDS as
Passive
.
8 – And then, connect the H1 connector to the new module, and after that set the parameter
FUNCTION_IDS as
Backup
.
9 – Even in the transducer, configure the parameter SYSTEM_OPERATION as
Redundant
. Wait
until the
Live Lists
of all channels are completed.
10 – For each one of the channels used for the configuration, right-click in the
Fieldbus
icon and
choose the
Download Schedule
option.
Placing the system into operation after a general power outage
There is also a procedure to place the modules into operation after both have been turned off. If you
turn them on at the same time, there will be many collisions on the H1 network because both
modules (
Active
and
Backup
) will try to become the LAS at the same time. It will cause a delay for
the perfect communication to be established. In order to avoid this problem, turn on first the
Active
module and wait until it is on line. Then, turn the
Backup
module on.
