19 WCC Lite internal signals

Overview

The WCC Lite contains several internal data points for readout and control which can be accessed via the Pooler service.

Configuration

Devices section

In the devices section, only the protocol, scan_rate_ms and poll_delay_ms are to be configured for this type of device.

WCC Lite internal signals

Parameter	Type	Description	Required	Default Value (when not specified)	Range
name	string	User-friendly device name	Yes
device_alias	string	Alphanumeric string to identify a device	Yes
protocol		Protocol identifier Internal data	Yes		Internal data
scan_rate_ms	integer	Update rate	No	60000
poll_delay_ms	integer	Poll delay	No	200

It is advised to set scan_rate_ms to a value greater than 5000 milliseconds as frequent scans may significantly overload the internal data process.

The signals section

tag_job defines the tagging job. This can be set to gpio, board, netstat, gsm, led and process. tag_job_todo defines the job sub­ job. This field should address the particular point of interest. There is also an optional extra trigger parameter. It allows changing when the signal switches between on and off and is only applicable to LED and GPIO parameters that can be set. The default trigger is value>0. When a trigger column is added the trigger can be changed by entering i.e. "value>10". This is useful when mapping a source signal to trigger a relay.  An example of how to use a trigger is in the example configuration attached to this page. Excel Configuration Example

Digital-input GPIO will only work with Hardware versions 1.4 and above.

Certain GSM parameters will only work if a SIM card is inserted.

job_todo	Description	tag_job_todo	Description
gpio	ReadOnly parameters	digital-input	If the value is 1 then the digital input pin is high. If it's 0 then the digital-input value is low.
		rs232-enable	If the value is 1 then rs232 is enabled. If the value is 0 then  rs485 is enabled.
	Parameters that can be set.	sim-detect	Informs whether the sim is inserted.
