4. DeviceNet Allen Bradley In a typical CAN network each device is assigned a unique CAN node address ID to arbitrate network communication Depending on the application protocol used these IDs are assigned in the range of 0 to 253 Therefore up to 254 devices may be logically attached to a CAN network However the use of standard CAN transceiver chips limits the number of physically attached devicesto 64 Thus to reach the logical limit of 254 devices up to three smart CAN repeaters are used to connect groups of devices together A CAN network without repeaters should be limited to a maximum cable length of 1500 feet assuming a Baud rate of 125 kHz With repeaters this limit may be extended to 6000 ft In conclusion the HE200CGM100 CAN repeater s 1000V isolation virtually eliminates problems associated with ground potential differences that are inherent in long cable drops on many local area networks CAN Network Repeater Module Page 2 rr i eee COTOO TO HE200CGM100 SPECIFICATIONS I O SPECIFICATIONS PARAMETER MINIMUM MAXIMUM UNITS POWER LOAD SPECIFICATIONS PARAMETER MINIMUM MAXIMUM UNITS I CI RI I CI CI RS CAN Network Repeater Module Page 3 HE200CGM100 LED INDICATORS e There are four LED indicators on the HE200CGM100 Below is a description of each of them Indicator _ Description is active receives data RS232 Port TX Green ON when RS232 Port transmits data HE200CGM100 CONNECTOR PINOUTS
