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.

Note that the Strato I/O Server doesn't count in the I/O servers license total, so you don't need an extra I/O Server license to use Strato with HSYCO.

High Availability

• Shutdown when inactive: defaults to false.

Options

ID	Default	Values	Description
watchdog	false	true	enables the hardware watchdog and automatically generates the heartbeat signal
		false	disables the hardware watchdog
shutdown_minutes	0	0	no automatic shutdown after power failure
		int > 0	the driver will command the operating system shutdown and hardware power off after N minutes of back-up battery operations during a power failure. The Strato board will automatically power-up the Pi when power is restored
quiet	false	true	enables audible alarms on power failure
		false	disables audible alarms on power failure

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:
