According to being sent to the controller based on FPGA.
8. communication device according to claim 7, which is characterized in that the Date Conversion Unit will have same timestamp
The first kind data, break into a bag data, be then packaged into ether together with the target MAC (Media Access Control) address, source MAC
In the Second Type data that net can identify.
9. communication device according to claim 7, which is characterized in that the communication device further includes diagnosis unit, described
Diagnosis unit is for judging whether have during the controller and the human-computer interface device are communicated therebetween
Network failure；Wherein, in a scheduled duration after side sends data, when on the other hand not receiving data, determine communication network
In network failure state.
10. communication device according to claim 6, which is characterized in that the Date Conversion Unit will according to NNet agreement
The first kind data are converted to the data of Second Type, and the data length of the Second Type is fixed；And institute
State the data that data transmission unit sends the Second Type according to fixed time interval.
11. a kind of I&C system, which is characterized in that the I&C system includes: controller based on FPGA, based on operating system
Human-computer interface device, and the I&C system communication device such as claim 6-10 as described in any one, the communication dress
