14.9 Communication
When communication is activated, the impact on fault handling is as follows:
• Fault status messages are always delivered via bus and can be further handled by
other Synco devices
• Fault status messages from other Synco™ 700 devices are shown on the controller
• Fault status messages from other Synco™ 700 devices can be delivered to a fault
relay
Fault status messages can be acknowledged from a remote location (e.g. from the
operator station using the OCI700.1 / OCI702 service tool).
It can be selected whether fault status messages with self-holding may also be reset
from a remote location or whether this must always be made locally.

Conversely, the controller is not able to acknowledge fault status messages on other
controllers.
14.10 Fault relay
To pass on the fault status messages, or to optically or audibly indicate them on the
control panel, for example, the 2 fault message outputs Fault relay 1 and Fault relay 2 of
the function block can be configured to any 2 free outputs N.Q…

For each of the 2 fault relays, the following settings can be made:
• Fault priority:
Priority at which the relay shall be energized
• Signaling
The following signaling variants are available:
− Internal fault (optically): The fault relay only indicates internal faults and remains
energized until the faults are no longer present
− Internal fault (audibly): The fault relay only indicates internal faults and remains
energized until the fault is acknowledged
− Fault via bus (audibly): The fault relay only indicates faults from the bus and
remains energized until the fault is acknowledged
• Inversion
− "No" means: In the event of fault, the relay will be energized
− "Yes" means: In the event of fault, the relay will be deenergized
