IonoPiMax

Iono Pi Max is an extremely versatile industrial server with a huge variety of Input/Output lines and standard communication interfaces, all routed to the incredibly powerful quad-core processor of the Raspberry Pi.

Iono Pi Max

This driver provides support for a local installation of HSYCO on Iono Pi Max itself. The Raspberry Pi OS Kernel module for Iono Pi Max must be installed. The kernel module documentation is available at GitHub and the Iono Pi Max User Guide.

HSYCO Configuration

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

Note that the IONO Pi Max 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 IONO Pi Max with HSYCO.

High Availability

• Shutdown when inactive: defaults to false.

Options

ID	Default	Values	Description
startupevents	false	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	250	10 <= n <= 30000	the data acquisition interval, in milliseconds
watchdog	always	always	enables the hardware watchdog and automatically generates the heartbeat signal (when the HSYCO main control loop is running normally, approximately every 10 seconds). The watchdog timeout is set to 60 seconds while HSYCO is running, or to 1 hour when HSYCO is manually stopped (sysctl stop hsyco) and when it is starting
		true	enables the hardware watchdog only while HSYCO is running, and automatically generates the heartbeat signal (when the HSYCO main control loop is running normally, approximately every 10 seconds). The watchdog timeout is temporarily set to 1 hour when HSYCO is starting
		false	disables the hardware watchdog
		ignore	doesn't change the watchdog configuration parameters
shutdown_minutes	0	0	no automatic shutdown after power failure
		N > 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. Iono Pi Max will be turned back on when power is restored
quiet	false	true	enables audible alarms on power failure
		false	disables audible alarms on power failure

Datapoints

The Iono Pi Max implements all data points provided by the underlying Iono Pi Max kernel module. Refer to the documentation is available at GitHub.

Each readable file name exposed by the kernel module under the /sys/class/ionopimax/ sub-directories appears as a data point with id <subdir>.<file>. For example, as the buzzer's status file is /sys/class/ionopimax/buzzer/status, the corresponding data point is "buzzer.status".

Command files that are marked as write only in the documentation (W), are not shown as visible data points in HSYCO, but can be used in the IO events action or ioSet() methods to send a command.

For example, if "max" is the id assigned to the Iono Pi Max I/O Server, then:

TIME : IO max.buzzer.beep = 1000

will make the buzzer beep for 1 second (1000 ms).

Note that "max.buzzer.beep" is not visible in the Status Browser and doesn't generate events, because it is write only, and only the "max.buzzer.status" data point will be visible, with a value of 0 if the buzzer is not active, or 1 if active.

Additional datapoints

ID	Value	R/W	Description
shutdown	1	W	initiate a power cycle
dualsdsync	0	R	manual SD synchronisation completed
	1	R	manual SD synchronisation pending or in progress
		W	initiate SD synchronisation (only available when the dualsdsync option is set to "manual"
dualsdsync.status	N	R	status of the last SD synchronisation run: >=0: number of files synchronised -1: error while updating files (see logs) -2: alternate SD card not available or file system error
