Provides nodes to access EWIO2 interfaces like IOs and metering - from Node-RED

<script type="text/markdown" data-help-name="EWIO2 - Digital IN">
Read digital input value of EWIO2.

Digital inputs provide the switching state or pulse counter value (if configured as pulse counter).

### Details
Every node represents one digital input of an EWIO2.
Any digital input of EWIO2 and to EWIO2 connected Modbus RTU I/Os can be used.

Node provides every change of digital input to nodes output.
Precondition is that 'Rising edge at EWIO2' or 'Falling edge at EWIO2' (for switching state) or 'Change in value at EWIO2' (for pulse counter) is set in confuguration menu.

Node can read and configure digital inputs of EWIO2 by nodes input signals:
- **topic**: "trigger"
  - Read digital input
- **topic**: "pulse" + **payload**: true/false
  - Activate / deactivate pulse counter
- **topic**: "counter" + **payload**: number
  - Set pulse counter value

Precondition is that 'Input signal at node' is set in configuration menu.

The current status of the node is also output of node. 'state' can be 'ok', 'warning' or 'error', 'text' and 'source' correspond to the general 'status' node.

Furthermore, a 'topic' can be specified in configuration menu, which will be additional output of node.

### Inputs
: payload (boolean | number) : Desired configuration value
: topic (string) : "trigger", "pulse" or "counter"

### Outputs
: payload (boolean | number) : Current switching state or pulse counter value
: topic (string) : Optional 'topic'
: status (Object) : Status of node, with 'state', 'text' and 'source'

### Configuration menu
This node uses the connection of EWIO2 node, to connect to an EWIO2.
All available digital inputs of EWIO2 and to EWIO2 connected Modbus RTU I/Os are loaded and can be selected.
Live data of switching state or pulse counter value and if port is configured as pulse counter, are shown for the selected port.
Additionally a topic can be configured as nodes output.

### Properties
: EWIO2 (select) : EWIO2 node, to connect to EWIO2
: Port (select) : Digital input of EWIO2
: State / Value (boolean | number) : Switching state / pulse counter value of digital input
: Pulse count. (boolean) : Port is configured as pulse counter
: Input signal at node (boolean) : Node reacts to input signal
: Rising edge at EWIO2 /<br>Falling edge at EWIO2 /<br>Change in value at EWIO2 (boolean) : Node reacts to change of digital input
: Topic (string) : Additional output of topic
: Name (string) : User defined name of node
