Diagnostic functions

The diagnostic functions support supervisory systems with their

display, monitoring and archiving functions. For this purpose these

diagnostic functions are available:

• Device function: The switching actuator cyclically sends a function

signal allowing a supervisory system to control its function.

• Status indication: Sending of the switching status can be activated

per output. The current status can be read via the bus or transmitted

cyclically.

• Status retrieval: For all outputs sending the current status can be

triggered via a central status retrieval object. With a single message a

visualization (e.g. IP Control Center) can update its status informa-

tion and display.

• Switching cycle count with or without threshold monitoring: The

switching cycle count can be activated per output. The number of

switching cycles can be read via the bus. This allows for monitoring

of the switching cycles and a switching cycle dependent mainte-

nance. If the threshold monitoring is activated the device sends a

signal onto the bus when the set threshold is reached. The excee-

dance of the threshold is automatically signaled respectively this can

be sent as an email by the IP Control Center or can be displayed by a

warning light.

• Operating hour count with or without threshold monitoring: The

operating hour count can be activated per output. The number of

operatin

g hours can be read via the bus. This allows for monitoring

of the operating hours and an operating hour dependent

maintenance,

e.g. if after 10,000 hours of operation lamps shall be replaced. If the

threshold monitoring is activated the device sends a signal onto the

bus when the set threshold is reached. The exceedance of the

threshold is automatically signaled respectively this can be sent as an

email by the IP Control Center or can be displayed by a warning light.

The control, override and diagnostic functions can be realized in the

device itself without additional control modules or a controller.

With these functions the switching actuators are getting into the

functional class of a micro-PLC with powerful relays.
