14.2.4 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.

Explanation
Check cycle time for SMAI and 3PHSUM blocks connected
to Disturbance Report blocks. SMAI and 3PHSUM blocks
shall have the same cycle time.
LDCM transmitter is missing connections. Check the
LDCMTRN block.
System frequency is different in local and remote end of
LDCM link.
Check the parameter FrequencySel at both ends.
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.
