Description
If a Repetitive Diff Current Alarm is activated, the target
blocks permanently
If a Repetitive Invalid BU Currents alarm is activated, the
target blocks permanently
If a Repetitive Output Relays blocked alarm is activated, the
target blocks permanently
In case of Repetitive BU restarts , the target blocks
permanently
In case of Repetitive CU restarts , the target blocks
permanently
If the diagnosis detects any HW related failure , the CIM
blocks permanently
If the diagnosis detects any HW related failure , the CPC
blocks permanently
If the diagnosis detects any HW related failure , the BU
blocks permanently
If the required PSM HW module is missing, the target blocks
permanently
If the configured/required redundant PSM HW module is
missing, the target blocks permanently
If the configured/required BIO HW module is missing, the
target blocks permanently
If the required TRM HW module is missing, the target blocks
permanently
If the configured/required PIO HW module is missing, the
target blocks permanently
If the configured and physical assembled TRM HW module
do not match, the target blocks permanently
If the configured and physical assembled PSM HW module
do not match, the target blocks permanently
If the configured and physical assembled redundant PSM
HW module do not match, the target blocks permanently
If binary input or output channels configured on physical
channels that are not available, the target blocks
permanently
If an IP address configuration problem occurs (The main
reason is that two interfaces are configured with the same IP
address), the target blocks permanently
Description
If the error handling detects start-up or repetitive error
causes (see Table 15), the permanently blocked state is set
