How to resolve a Connection Failed error on Omron Network Hardware?
If a connection fails because device parameters (such as the variable name and size) did not match in the originator and target, or connection resources are insufficient, correct the device parameter settings and download the device parameters again from the Network Configurator.
What causes a Tag Data Link Error in Omron SYSMAC CJ1W-EIP21, and how can I fix it?
If a timeout occurred in the tag data link because tag data was not received from the target within the specified timeout time, check these items: * Is the registered node’s power supply ON? * Is the cable connected? * Is the cable damaged or loose? * Is there excessive noise?
How to fix a Node address setting error on Omron SYSMAC CJ1W-EIP21 Network Hardware?
If the node address set on the switches is invalid (00 or FF), set the node address correctly and restart the EtherNet/IP Unit or built-in EtherNet/IP port.
How do I resolve a Routing table error on Omron SYSMAC CJ1W-EIP21?
If there is a logic error in the routing table settings, create the routing tables again.
What to do if Omron SYSMAC CJ1W-EIP21 shows a CPU Unit memory error?
If a parity error occurred during an operation such as reading the routing tables, register the routing tables in the CPU Unit again and restart the CPU Unit. Replace the CPU Unit if the error recurs.
How can I fix an I/O refresh error on Omron Network Hardware?
If the EM Area bank in which the device parameters were set was converted to file memory while the tag data link was operating, stop using the EM Area bank (in which the device parameters were set) as file memory, or correct the device parameters.
What does an Address mismatch error mean on Omron SYSMAC CJ1W-EIP21, and how can I resolve it?
If the target IP address conversion method is set to Automatic generation, but the last byte of the local IP address does not match the value set on the Node Address Setting Switch, check the IP address and the Node Address Setting Switch setting.
How do I resolve an I/O table not registered error on Omron Network Hardware?
If the CPU Unit’s I/O table is not registered, create the I/O table.
What does Memory Access Error mean on Omron SYSMAC CJ1W-EIP21, and how do I fix it?
If an error occurred in the Unit's non-volatile memory itself, download the Unit Setup from the tab pages of the Edit Parameters Dialog Box of the CX-Programmer and download the device parameters from the Network Configurator. If the error recurs, replace the EtherNet/IP Unit or (for a built-in EtherNet/IP port) the CPU Unit.
What to do if there is an IP Address Duplication in Omron SYSMAC CJ1W-EIP21 Network Hardware?
If the IP address of the EtherNet/IP Unit or built-in EtherNet/IP port is the same as the IP address set for another node, check the IP addresses set on other nodes. Restart the EtherNet/IP Unit or built-in EtherNet/IP port after correcting the IP address settings to eliminate duplications.
