Hardware re-configuration
When adding, removing or moving a hardware modules in an IED ( for example, I/O modules,
communication modules or time synchronization modules) a set of procedures must be followed.
Adding a new module in to an IED
Procedure:
1.
Switch the IED off and insert the new module.
2.
Switch the IED on, wait for it to start, and then perform a HW reconfig.
3.
Perform a license update in PCM600.
The new module is now available in PCM600 and is ready to be configured.
Removing a module from an IED
Procedure:
1.
Remove all existing configuration for the module in PCM, and write that configuration to the IED.
2.
Switch the IED off and remove the HW module.
3.
Switch the IED on, wait for it to start, and then perform a HW reconfig.
4.
Perform a license update in PCM 600.
Moving a module in an IED from one position to another
Procedure:
Railway application RER670
Commissioning manual
If any configuration that makes the module needed remains, then the HW reconfig
will not remove the module.
The module will still be needed. An error indication for the module will appear, if the
module is physically removed from the IED and the IED is restarted with some part
of the configuration still requiring the module.

Explanation
LDCM analog latency is different in local and remote.
Check the LDCM parameters AnalogLatency and
remAinLatency at both ends.
HW configuration necessary to configure RSTP on
<Access Point> is missing. Please contact the SA - T
Supportline to fix this error.
Access points can be any of these : AP_1, AP_3
Calculated phase-earth values are used from one or
more SMAIs configured for phase-phase inputs, without
connected N input. However, this configuration,
combined with unbalanced three-phase input, will result
in incorrectly calculated phase-earth values. This in turn
may result in maloperation of functions connected to
SMAIs configured this way, if the function uses phase-
earth based values. Further, if SUM3PH is connected to
such a SMAI, then its output values will be incorrect, and
connected functions may maloperate. To remedy the
situation, please revise the configuration from this
perspective.
