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-capble device and an IPv4-capble device has not been carried out in a system wherein the IPv6-capble device and the IPv4-capble device are mixed. An entry of a live list is retrieved when SM Device Annunciation is received from the IPv6-capble 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-capble device and the IPv4-capble device can be carried out, and devices connected to the system can be controlled.
