Parker HannifinCANopen ConnectionPerform the following steps to resolve CANopen network problems.• Confirm completion of the installation test on page 90.• Verify that each node employs the correct pinout. For the ACR90x0CANopen connector pinout, see Table 32 on page 58.• The ACR90x0 controller provides a network-status LED, whichindicates the state of the CANopen network interface. Use Table 58 onpage 99 to resolve issues indicated by the LED states.• CANopen slave nodes typically have a network-status LED; refer tothe device’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 92.2. Verify the cable pin out matches the ACR90x0. See Ethernet CableSpecification on page 92.3. The ACR90x0 controller provides a network-status LED, which indicatesthe state of the Ethernet connection. See Table 59 on page 99.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 ACR90x0.See Ethernet Cable Specification on page 92.5. 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 ACR90x0 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 ACR90x0 orchange the IP address of the conflicting device.2. If you see a “timeout” message, then the ACR90x0 is properlyconfigured and is network accessible. Re-attach the ACR90x0Ethernet cable.b. If a “timeout” message is seen, then the ACR90x0 has an invalid IPaddress or subnet mask setting. Determine the correct setting andupdate the ACR90x0.100 ACR9000 Series Hardware Installation Guidewww.comoso.com
