'''<div id="Equipment Type"></div>'''<br />
==Equipment Flags==<br />
The following equipment flags (of the form EQ_xxx) are supported in the Equipment [[Equipment List Parameters#Type|Type]] field in the Equipment structure.<br />
The selected flag determines the Equipment Type.<br />
<br />
===EQ_PERIODIC ===<br />
; Periodic Event<br />
:In this mode no hardware requirement is necessary to @ref FE_tab_event_trigger "trigger" the readout function. Instead, the @ref FE_tbl_ReadoutRoutine "readout routine" associated with this equipment is called periodically.The @ref FE_tbl_Period "Period" field in the equipment declaration is used in this case to specify the time interval between calls to the readout function. See @ref FE_other_event "example".<br />
<br />
===EQ_POLLED===<br />
;Polling Event<br />
: In this mode, the name of the routine performing the @ref FE_tab_event_trigger "trigger" check function is @ref FE_poll_event "poll_event()". This routine must be provided in the frontend.c by the user. As polling consists of checking a variable for a TRUE condition, if the loop count is infinite and the condition never becomes TRUE, the frontend would not be able to respond to any network commands. Therefore the loop count is determined when the frontend starts for the first time so that it returns after a given time-out if no event is available. This time-out is usually of the order of 500 milliseconds. <br> The EQ_POLLED equipment type is mainly used for data acquisition based on a hardware condition becoming TRUE, at which time the @ref FE_tbl_ReadoutRoutine "readout routine" associated with the equipment is called. See @ref FE_poll_event "example".<br />
<br />
<br />
===EQ_INTERRUPT===<br />
; Interrupt Event<br />
: This modeis similar to the @ref FE_tbl_EqPolled "EQ_POLLED" mode except a hardware interrupt is used to @ref FE_tab_event_trigger "trigger" the event instead of a polling loop. Instead of passing a pointer to the polling routine, in EQ_INTERRUPT mode a pointer to the <b> interrupt configuration routine </b> is passed to the system. Midas requires complete configuration and control of the interrupt source. This is provided by an interrupt configuration routine called @ref FE_interrupt_event "interrupt_configure()" that must be provided in the frontend.c by the user. When a valid interrupt is received, the @ref FE_tbl_ReadoutRoutine "readout routine" associated with the equipment is called.See @ref FE_interrupt_event "example".<br />
<br />
<br />
<br />
===EQ_MULTITHREAD===<br />
;Multithread Event Readout<br />
:This equipment type implements themulti-threading capability within the frontend code. The polling isperformed within a separate thread and uses the@ref rbfunctionc "Midas Ring Buffer Functions" (rb_xxx) for inter-thread communication.EQ_MULTITHREAD is similar to @ref FE_tbl_EqPolled "EQ_POLLED" mode, except for the polling function which in the case of EQ_MULTITHREAD resides in a separate thread. This new type has been added to take advantage of the multi-core processor to free up CPU for tasks other than polling.<br />
<br />
<br />
<br />
=== EQ_SLOW===<br />
; Slow Control Event<br />
: This flag declaresthe equipment as a Slow Control Equipment. This will enable the call to the '''idle''' function part of the class driver. This flag also causes event data to be sent automatically to the <span style="color: purple; font-style:italic;">/equipment/variables/</span> ODB tree.<br />
<br />
<br />
<br />
===EQ_MANUAL_TRIG===<br />
; Manual triggered event<br />
: This flag enables the equipment to be @ref FE_Manual_trig_mode "triggered" by a remote procedure call (RPC). If EQ_MANUAL_TRIGGER is selected, the web interface will provide an extra button to trigger the equipment. The event may also be triggered by a client via RPC. @ref FE_manual_trigger "See example."<br />
<br />
<br />
<br />
=== EQ_EB===<br />
<br />
;Event run through event builder<br />
: This flag identifies the equipment as a <b>fragment event</b> and should be ORed with the EQ_POLLED in order to be identified by the [[Event Builder]]. <br />
<br />
<br />
<br />
=== EQ_FRAGMENTED===<br />
; Fragmented Event<br />
: Flag enabled large events (beyond the Midas configuration limit) to be handled by the system ('''see WARNING below'''). This flag required that a valid ''max_event_size_frag'' variable was defined in the user [[Frontend Operation#Frontend|Frontend]] code. The ''max_event_size variable'' was used as fragment size in this case. This option was meant to be used in experiments where the event '''rate''' was not an issue but the '''size''' of the data needed to be extremely large. @ref FE_fragmented_event "See example."<br />
<br />
<br />
<br />
<div style="background-color:mistyrose;"><br />
:: '''WARNING'''<br />
::* This flag is obsolescent (not maintained). It was added for small memory cpus (e.g VxWorks PPC) to send very large events (beyond the Midas configuration limit) back to the host computer.<br />
::* With modern large-memory cpus (e.g. VMIC), '''instead of using this flag, the buffer sizes should be increased to accommodate a large event''' (see [[Event Buffer]]). <br />
::* The fragmented event mechanism is '''not to be confused''' with "event fragments" used by the [[Event Builder]].<br />
