【正文】 umber in the message matches the serial number defined in the host system, the result will be zero. Otherwise, the “init” request has failed and the result field will be nonzero. The synch_time field contains the current time in the host. The value is four bytes long and represents the number of seconds elapsed since 00:00:00 Greenwich mean time (GMT), January 1, 1970.13 / 64 of jobThe “start” request message is sent from the host to the Husky machine to signal the start of a new job. The Husky OI will clear setup number one and all of its production counters.message_size 2 byte integer0x03 2 byte integertandem_side 1 byte integerThe “start” response message from the Husky machine is:message_size 2 byte integer0x8003 2 byte integerresult 2 byte integerThe tandem_side field is only valid for Tandem174。 machines, this field should be ignored.This message has the same format as the “read” response message, except for the tandem_side field. The result field will always be zero.No response is expected to the “cycle” indication message.The Husky machine will send all events as recorded in the event log to the host as they occur. The event text is sent to the host in all languages supported by the OI.When an event occurs, the Husky machine sends the following “event” message to the host:message_size 2 byte integer0x50 2 byte integerdate 8 byte ASCIItime 8 byte ASCIInumber_languages 2 byte integerlanguage_code1 1 byte ASCIItype_text1 8 byte ASCIIevent_text1 255 byte ASCIIlanguage_code2 1 byte ASCIItype_text2 8 byte ASCIIevent_text2 255 byte ASCII...The date and time field contains the time on the Operator Interface when the event occurred, as displayed on the Machine Events History screen. The date format is YYMMDD and the time format is HH:MM:SS on a 24hour clock.The number_languages field indicates the number of translations sent in this message.The language_codeN fields indicates the language which is used for the event text.The typeN fields contain the 8 character event types as listed above, translated into the specified language.The message_textN fields contains the event text (See Appendix E), as it would be displayed on the Machine Events History screen or extracted by the log conversion program (), in the specified language.No response is expected to the Event Message.21 / 64 InterruptionsThe host can obtain cycle interruption information by sending a query to the Husky machine. The Husky machine will also send this information whenever it detects a cycle interruption. The cycle interruption text is sent to the host in all languages supported by the OI.Husky initiated cycle interruptionsWhen the Husky machine detects a cycle interruption, it sends the following “cycle interruption” message to the host:message_size 2 byte integer0x21 2 byte integerresult 2 byte integernumber_languages 2 byte integerlanguage_code1 1 byte ASCIIcycle_interruption_text1 50 byte ASCIIlanguage_code2 1 byte ASCII cycle_interruption_text2 50 byte ASCII...The result field contains a code to indicate if the cycle interruption text is valid. If the cycle interruption text is valid, the result field will be zero, otherwise the result field will be nonzero.The number_languages field indicates the number of translations sent in this message.The language_code field indicates the language which is used for the cycle interruption text.The cycle_interruption_text field is a text field describing the cycle interruption in the specified language (see Appendix B).No response is expected to the “cycle interruption” indication message.Cycle interruption QueryThe host may query the OI for the last cycle interruption using the “cycle interruption query” message:message_size 2 byte integer0x22 2 byte integerThe “cycle interruption query” response from the Husky machine is:message_size 2 byte integer0x8022 2 byte integerresult 2 byte integernumber_languages 2 byte integerlanguage_code1 1 byte ASCIIcycle_interruption_text1 50 byte ASCIIlanguage_code2 1 byte ASCIIcycle_interruption_text2 50 byte ASCII...This message has the same format as the “Husky initiated cycle interruption” message described earlier.23 / 64 SPC parametersIf the SPC option has been installed, the host may obtain the SPC sample size, sampling period, sampling method, or specification limits in any of the following ways:? if the Husky machine detects a change in any of the SPC parameters, it will send the host an SPC indication message? the host may request the parameters at any time by sending the Husky machine an SPC parameters query messageHusky initiated SPC parametersWhen the Husky machine detects a change in the SPC sample size, sampling period, sampling method, or any of the specification limits, it will send the following SPC indication message to the host.message_size 2 byte integer0x30 2 byte integerreserved 1 byte integerresult 2 byte integersample_size 2 byte integersample_period 2 byte integersampling_method 2 byte integernumber_of_variables 2 byte integerlow_limit1 4 byte IEEE floating pointhigh_limit1 4 byte IEEE floating pointlow_limit2 4 byte IEEE floating pointhigh_limit2 4 byte IEEE floating point...The result field contains a code indicating if the SPC option is installed on the Husky machine. If the option is installed the result field will be zero, otherwise the result field will be nonzero.The sample_size field contains an integer which specifies the number of observations per sample.The sample_period field contains an integer which specifies the number of cycles from which to collect one sample (one sample will be collected every sample_period cycles).The sampling_method field
