Relay Outputs
Fig. [. . . ] The I/O functionality can be configured using either CARE 7. 01. 00 (or later) or the LNS plug-in. The LNS plug-in cannot be used to configure the switching logic functionality. NOTE: Do not use a browser for configuration as there is then a high risk of incorrect configuration.
LONMARK Objects
The Excel Smart I/O Compact features: · One Node Object (Obj#0); · Three Open-Loop Sensor objects (Obj#1-3), one for each physical universal input; · Three Open-Loop Sensor objects (Obj#4-6), one for each physical digital input; · Three LONMARK open-loop actuator objects (Obj#7-9), one for each relay.
Response Time for Switching Logic
If you require a fast response time, you must use digital inputs in a switching logic table. Analog inputs used as slow digital input require a longer response time. Typical response time for reaction to DI change: · If only a single switching table is defined, the reaction time to a digital input change is less than 0. 5 s. Typical response time for reaction to slow DI change: · If only a single switching table is defined, the reaction time to a slow digital input change is less than 1. 5 s.
LONMARK Node Object
The LONMARK node object (see Fig. The definition of SNVT_obj_request includes an object ID field to allow the node object to report status conditions for all objects in a node. The node self-documentation string lists the names of the individual LONMARK objects, allowing a network management node or tool to display useful information about an Excel Smart I/O Compact; it also states (in the optional part after the semicolon) that the node is an Excel Smart I/O Compact, and lists its version number. The Excel Smart I/O Compact has a configurable receive / sent heart beat time (0. . . 6553 s).
INTEROPERABILITY
The Excel Smart I/O Compact is compliant with LONMARK Application Layer Guidelines V3. 3.
LONWORKS Network Interface
The Excel Smart I/O Compact is equipped with a 10-MHz 3150 Neuron® chip. It communicates within the LonWorks network at a rate of up to 78 kilo baud via an FT-X1 Free

There is one common receive heartbeat time for all input NV's supporting a receive heartbeat. A communication failure behavior can be configured to define the desired action in the event that an update of nviDoSwitch[] is missing within the configured receive heartbeat time. All sensor objects have an output NV showing the actual state of the physical output. There is just one common send heartbeat time.
