此握手字指示新的非循环响应消息何时
由PROFIBUS驱动程序接收。如果值为零（0），则没有响应消息
已收到。如果该值为非零，则已收到响应消息，并且
存储在字146至289中。该数据应由其他网关传输
外部处理协议。非循环消息从外部发送后
如果已处理，则应通过设置
地址为零，表示准备接收和处理新的非循环响应
消息该区域保存PROFIBUS主设备接收到的报警非循环信息
装置有关此非循环的说明，请参阅邮箱消息（第75页）
消息消息的头（前32个字节）以小端格式存储
以使其更易于处理。This handshake word indicates when a new acyclic response message has been
received by the PROFIBUS driver. If the value is zero (0), no response message has
been received. If the value is non-zero, a response message has been received and
stored in words 146 to 289. This data should be transferred by the other gateway
protocol for external processing. After the acyclic message has been externally
processed, a message should be returned through the other protocol that sets this
address to zero, to indicate readiness to receive and process a new acyclic response
message. This area holds the alarm acyclic message received by the PROFIBUS Master
device. Please refer to Mailbox Messaging (page 75) for a description of this acyclic
message. The header (first 32 bytes) of the message is stored in little-endian format
to make it easier to process.
