摘要： Disclosed is an instrumentation control system, including: a first field device; and a second field device coupled to the first field device via a fieldbus. The first field device includes: a transmitting buffer to store data to be transmitted; a transmitter; and an inquiry processing section to cause the transmitter to retransmit the data stored in the transmitting buffer to the second field device in response to a request from the second field device. The second field device includes: a receiving buffer to store the data transmitted from the first field device; a checking section to determine whether the data stored in the receiving buffer is normal or not, and to make a data retransmission request to the first field device if the data stored in the receiving buffer is not normal; and a processing unit to perform predetermined processing based on the data which is determined to be normal.

摘要： The invention is to solve the problem in that mutual communication between an IPv6-capable device and an IPv4-capable device has not been carried out in a system wherein the IPv6-capable device and the IPv4-capable device are mixed. An entry of a live list is retrieved when SM Device Annunciation is received from the IPv6-capable device, and a transmission IPv4 address is acquired from an IPv4 address pool if the entry is not found, thereby preparing translation rules so as to be stored in a translation rules storage section, while preparing an entry to be registered in the live list, whereby an IP address in a message is translated with reference to the translation rules. Further, a timestamp of the entry is updated every time when the SM Device Annunciation is received. Even if the address is contained in the message, the mutual communication between the IPv6-capable device and the IPv4-capable device can be carried out, and devices connected to the system can be controlled.
摘要翻译：本发明是为了解决在具有IPv6能力的设备和支持IPv4的设备混合的系统中尚未执行具有IPv6能力的设备与支持IPv4的设备之间的相互通信的问题。当从具有IPv6能力的设备接收到SM设备通知时，检索实时列表的条目，如果没有找到条目，则从IPv4地址池获取传输IPv4地址，从而准备转换规则，以便存储在翻译规则存储部分，同时准备要在实况列表中注册的条目，由此参考翻译规则翻译消息中的IP地址。此外，每当接收到SM设备通知时，更新条目的时间戳。即使地址包含在消息中，也可以执行支持IPv6的设备和支持IPv4的设备之间的相互通信，并且可以控制连接到系统的设备。
