- 76 - ACR9000 Hardware Installation GuideCANopen ConnectionPerform the following steps to resolve CANopen network problems.• Confirm completion of the installation test on page 67.• Verify that each node employs the correct pinout. For the ACR9000CANopen connector pinout, see Table 28 on page 37.• The ACR9000 controller provides a network-status LED, which indicatesthe state of the CANopen network interface. Use Table 53 on page 75 toresolve issues indicated by the LED states.• CANopen slave nodes typically have a network-status LED; refer to thedevice’s documentation for an explanation of the LED states andresolution of the issues indicated.Ethernet ConnectionPerform the following steps to resolve Ethernet network problems.1. Verify that you are using the correct type of cable. See Ethernet CableSpecification on page 69.2. Verify the cable pin out matches the ACR9000. See Ethernet CableSpecification on page 69.3. The ACR9000 controller provides a network-status LED, which indicatesthe state of the Ethernet connection. See Table 54 on page 75.Do not proceed until the status LED indicates an Ethernet Link has beenestablished.4. Verify a valid IP and subnet mask has been assigned to the ACR9000.See Ethernet Cable Specification on page 69.5. Test the IP and subnet assignment. At a DOS or command prompt typeping xxx.xxx.xxx.xxx where xxx.xxx.xxx.xxx represents the IPaddress. Compare the response to the following:a. If you receive a “reply from” message, do the following:Disconnect the ACR9000 Ethernet cable and type the pingcommand again.1. If you see “reply from” message, then another device orcomputer has already been assigned the same IP address.You can change IP address you assigned to the ACR9000 orchange the IP address of the conflicting device.2. If you see a “timeout” message, then the ACR9000 is properlyconfigured and is network accessible. Re-attach the ACR9000Ethernet cable.b. If a “timeout” message is seen, then the ACR9000 has an invalid IPaddress or subnet mask setting. Determine the correct setting andupdate the ACR9000.
