Their address is the same address, and they are distinguished by identification. The communication rate is 400kbps.
  • Page 36 The data frames stipulated in the CAN communication protocol have two formats, which are standard format and extended format, and the arbitration segments of the two formats are different. Acrel AIM-M300/SG insulation monitors uses the standard format, of which the arbitration segment has 11 bits.
  • Page 37 7.2.3.1 Startup command 01 01 Description: When the AIM-M300 series insulation monitoring device monitors the insulation faults in the isolated power system, it will issue a startup command to initiate the AIL150-4/8 fault locator. After receiving this command, the AIL150-4/8 fault locator begins the insulation fault locating.
