GEM for SIPLACE V5.01

S6F21 Host requests an Annotated 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).

This table lists the Variables for which the Host may set limits and the event which is

called in case of a Limits Monitoring transition.

For any event that exists on the Equipment, the event message will be sent to the Host

only if the reporting for that particular event has been enabled. In this "EVENT

SIGNALLING" section, assume that the Host has enabled the proper reporting so that

these events will be sent to the Host.

After the Host sets UPPERDB and LOWERDB values for a particular limit, the SIPLACE

will send an event message when a transition occurs across these boundaries. The

procedure for reporting is explained in the following chart and state chart diagram:
