Strato

Strato Pi is an expansion board developed by Sfera Labs for the Raspberry Pi computer board.

Strato Pi

Strato Pi implements a number of hardware features to expand the Pi and allow its use in professional applications:

• 9-28 Vdc extended-range power supply
• integrated UPS with external NiCd rechargeable battery
• real-time clock with dedicated back-up battery
• opto-isolated RS-232 or RS-485 serial port
• configurable hardware watchdog
• buzzer for audible feedback.

HSYCO Configuration

Add a STRATO I/O Server in the I/O Servers section of the Settings and set its parameters:

High Availability

• Shutdown when inactive: defaults to false.

Options

ID	Default	Values	Description
startupevents	true	true	generate IO events also during the driver’s start-up phase
		false	start generating events only after HSYCO is aligned with the current status of the system
pollinterval	0	0	the driver will use the push notifications sent by iono to monitor its changes
		int > 0	the driver will poll iono's state with the specified time interval (in seconds). Push notifications won't be enabled
input1	digital	digital	the specified multi-mode input will be read as digital signal (DI<n>)
input2
input3		voltage	the specified multi-mode input will be read as analog voltage (AV<n>)
input4		current	the specified multi-mode input will be read as analog current (AI<n>)
stabletime	100	int > 0	number of milliseconds an input must be stable before a push notification is sent by iono to HSYCO
minvariation	0.1	float > 0	minimun value variation (for analog inputs) to trigger a push notification
subscribehost		<host_name>	hostname or IP address to be used by iono to send push notifications. Leave blank to let the driver discover the local address

Datapoints

For inputs 1 to 4, depending on the 'input1' ... 'input4' options, only the corresponding datapoint will be created, i.e. di<n> (if digital), av<n> (if voltage) or ai<n> (if curent).

ID	Value	R/W	Description
connection	online	R	connection established
	offline	R	HSYCO can't connect to the device
do<n>	0	R	relay <n> (digital output) is off
		W	switch off relay <n>
	1	R	relay <n> (digital output) is on
		W	switch on relay <n>
di<n>	0	R	digital input <n> is low
	1	R	digital input <n> is high
av<n>	<val>	R	analog input <n> is reading a voltage equal to <val> (in Volts)
ai<n>	<val>	R	analog input <n> is reading a current equal to <val> (in mA)
ao1	<val>	W	set the analog output to <val> Volts

User Interface

To control a digital output (DO1 ... DO6), add a button or a buttonicon object to your project page and set its address field to the corresponding datapoint:
