# GCE Binding

This binding aims to handle various GCE Electronics equipments. IPX800 is a 8 relay webserver from gce-electronics with a lot of possibilities:

  • 8 Digital Input
  • 8 Relay (250V / 10A / channel)
  • 4 Analog Input
  • 8 Counters
  • Ability to cascade up to 3 extensions for a total of 32 inputs / 32 relay

Each IPX800 connected to openHAB must be configured with the setting 'Send data on status changed' on the website in M2M > TCP client.

To make it simple, IPX800 is a simple device that drives output and retrieves input. On input we generally connect push buttons (for instance house switchs), on ouputs we can connect light bulbs for instance.

Features of the binding:

  • Multi ipx support
  • Direct TCP connection
  • Auto reconnect
  • Simple clic/Long press
  • Pulse mode support

# Binding Configuration

There is no configuration at binding level.

# Thing Configuration

The IPX800v3 (ID : 'ipx800v3') accepts the following configuration parameters :

Property Default Required Description
hostname Yes IP address or hostname.
portNumber 9870 No TCP client connection port.
pullInterval* 5000 No Refresh interval (in ms)

The binding will query periodically the 'globalstatus.xml' page of the IPX to get fresh informations. This is especially usefull for Analog inputs and Counter as modification of these values on PLC side does not trigger any M2M message.

The thing provides four groups of channels.

# Digital Inputs

This represents the inputs of the PLC. Each can be open or closed. They are usually commuted by physical devices like pushbuttons, magnets...

# Digital Input Channels (contacts)

Each input will have these associated channels:

Group Channel Name Item Type R/W Description
contact portnumber Contact R Status of the actual port (OPEN, CLOSED)
contact portnumber-duration Number:Time R Updated when the port status changes to the duration of the previous state.

Associated events:

Channel Type ID Options Description Conf Dependency
portnumber-event Triggered on or after a port status change
PRESSED Triggered when state changes from OPEN to CLOSED
RELEASED Triggered when state changes from CLOSED to OPEN
LONG_PRESS Triggered when RELEASED after a long period longPressTime
SHORT_PRESS Triggered when RELEASED before a long period longPressTime
PULSE Triggered during CLOSED state pulsePeriod

# Configuration

Property Default Unit Description
debouncePeriod 0(*) ms Debounce time (ignores flappling within this time). No debounce is done if '0'.
longPressTime 0(*) ms Delay before triggering long press event. Ignored if '0'.
pulsePeriod 0(*) ms Period of pulse event triggering while the entry is closed. Ignored if '0'.
pulseTimeout 0(*) ms Period of time after pulsing will be stopped. None if '0'.
  • Values below 100ms should be avoided as the JVM could skip them and proceed in the same time slice.

# Digital Outputs Channels (relays)

Each output will have these associated channels:

Group Channel Name Item Type R/W Description
relay portnumber Switch R/W Status of the actual port (ON, OFF)
relay portnumber-duration Number:Time R Updated when the port status changes to the duration of the previous state.

# Configuration

Property Default Description
pulse false If set, the output will be in pulse mode, releasing it after the contact

# Counters Channels

Each counter will have these associated channels:

Group Channel Name Item Type R/W Description
counter counternumber Number R Actual value of the counter
counter counternumber-duration Number:Time R Updated when the counter status changes to the duration of the previous state.

# Configuration

This channel has no configuration setting.

# Analog Inputs Channels

Each analog port will have these associated channels:

Group Channel Name Item Type R/W Description
analog portnumber Number R Value of the port.
analog portnumber-duration Number:Time R Updated when the port status changes to the duration of the previous state.
analog portnumber-voltage Number:ElectricPotential R Electrical equivalency of the analogic value

# Configuration

Property Default Description
hysteresis 0 If set, the channel will ignore status if change (+ or -) is less than hysteresis/2

# Rule Actions

Multiple actions are supported by this binding. In classic rules these are accessible as shown in the example below:

Getting ipxActions variable in scripts

 val ipxActions = getActions("gce","gce:ipx800v3:43cc8d07")
 if(null === ipxActions) {
        logInfo("actions", "ipxActions not found, check thing ID")
        return
 } else {
        // do something with sunActions
 }

# resetCounter(counterId)

Resets the value of the given counter to 0.

  • counterId (Integer) - id of the counter.

# reset(placeholder)

Restarts the PLC.

  • placeholder (Integer) - This parameter is not used (can be null).

# Example
