In this state, the peripheral equipment is initialized and the machine process the

necessary reference runs. The data which was downloaded from the host is split in pieces

for the different subsystem of the machine

In this state, the SIPLACE is producing a board.

In this state, the Operator can teach fiducials, react on run-time-errors like empty feeders.

The SIPLACE has a fixed set of Variables which can be read by the Host. Each Variable

is identified by a unique Variable ID (VID). The Variables which exist are shown in

"Appendix A -- Variables".

There are three types of Variables: Status Variables, Data Variables, and Equipment

Constants. The Host can read Variables of any type, but can set values only for

Equipment Constants. The Host can read values for Status Variables and Equipment

Constant whenever the SIPLACE is On-Line, but values for Data Variables are typically

meaningful only immediately after certain Collection Events (CEIDs), and so are typically

reported only in Event Reports (S6F11).

The Host can send S1F1 at any time to determine if the SECS link is operational. The

SIPLACE responds with S1F2, if the equipment is in the ONLINE & COMMUNICATING

states. This indicates Model Number (MDLN) and Software Revision Number

(SOFTREV).

The Host can send S1F3 when the Equipment is On-Line to read Equipment Constants

from the SIPLACE.

The Host can send S2F13 when the Equipment is On-Line to read Equipment Constants

from the SIPLACE.

For this Equipment, S1F3 and S2F13 with a list of VIDs are essentially the same. That is,

either message can return Variables of any type. However, S1F3 with a zero-length list

will return only VIDs of type SV, and S2F13 with a zero-length list will return only VIDs of

type EC.

 6HWWLQJ(TXLSPHQW&RQVWDQWV

The Equipment Operator can change the value for Equipment Constants. Once the

Operator has changed an EC value, the Equipment will note the EqConstChange Event

(CEID 1000001). The VID for the changed EC will be reported to the Host in the variable

ECIDCHANGE (VID 1002036).

The SIPLACE has a fixed set of Events which can occur. Each Event is identified by a

unique Collection Event ID (CEID). The CEIDs which exist are shown in "Appendix B --

Collection Events".

When an Event occurs, the Equipment sends the appropriate S6F11 Event Report

message to the Host (if that particular event has been enabled). Event Reports are

defined by the Host (S2F33) and linked to a specific CEID (S2F35).

The Equipment allows the Host to enable and disable Event Reports using S2F37. If the

Host enables a CEID, for which no Event Report is defined, the Equipment will send a

"null" (no data) report when the event occurs.

The Host can "force" Event Reports on the Equipment using the following Event Report

Request messages:

S6F15 Host Requests an Event Report associated with a CEID.

S6F17 Host requests an Annotated Event Report associated with a CEID.

S6F19 Host requests an Event Report associated with a Report ID.

The SIPLACE supports Time Driven Trace initiated from the Host. The Host initializes a

trace using S2F23. The Equipment will send the data requested after the specified time

interval has expired. The data will be sent using the S6F1 (Trace Data Send) message.

The Equipment can handle several concurrent traces. The number of concurrent traces

is determined by the size of the trace data requested. The Equipment can support at

least four concurrent traces to a maximum size (i.e. all variables requested).

The equipment allows Host definition of trace data to exceed the one-block limit when

reported. That is, the SEMI E5 standard states that the S6F1 (Trace Data Send)

message is limited to a single SECS block; but the Equipment will allow this point to be

overlooked at the Host's request. If the Host does define trace data to be larger than one

SECS block, then the Equipment will send the multiple blocks, not preceded by the

S6F5/S6F6 Inquire/Grant scenario.

The Host can define limits for various Variables on the SIPLACE. When the appropriate

limits transitions occur, the SIPLACE will report this occurrence by sending an event to the

Host (if the event is enabled). The Host may define limits for a particular Variable through

the S2F45 (Define Variable Limit Attributes). Through this message, the Host may define

up to seven limits for each eligible Variable. For each limit (LIMITID), the Host defines an

UPPERDB and a LOWERDB. The SIPLACE generates events when a transition across

these boundaries occurs. The Host may set the rate at which the SIPLACE polls the

Variables to determine if a limit has been crossed by setting the GEMLIMITSTIMER

variable (VID 65).
