Event Keywords

An event is defined as a keyword that identifies the event type, usually followed by one or more parameters and conditional operators. Every keyword uses a specific syntax that interprets parameters according to its own rules.

I/O Servers

IO

Triggered by a status change of any data port of an I/O server.

Event	State	Description
IO name	transient	any change of an I/O variable
IO name = value IO name > value IO name < value IO name >= value IO name <= value	stable	the value is equal, greater, greater or equal, less, less or equal to the given value.  The names and values of the I/O variables are specifically related to the type of I/O server. Values can be numeric or strings.

Parameters:

• name - the data point name of the input or output port. According to the type of server, the format changes but it generally appears as server name, as declared with the ioServers parameter in hsyco.ini, followed by a dot and the input/output port name. See the Application Notes for more information.

Examples:

IO tempmeter.indoor > 25.5
IO contacts.c1 = 1

IOSTART

This event indicates that the connection with an I/O server has been correctly established.

It should be safe to associate this event with actions that set the I/O server writable variables.

Event	State	Description
IOSTART id	transient	Triggered by the start of the communication thread of each I/O server - once for each server at the beginning of the execution of HSYCO, and also after every reboot of the communication thread, for example after communication errors

Parameters:

• id - the I/O server number, starting from 0, based on the listing order of the ioServers parameter in hsyco.ini; If only one I/O server is available, it can be omitted.

Examples:

IOSTART: IO contacts.c1 = 1
IOSTART 2: IO relays.door = 1
