:6Ah error in the DDE/OPC Communications Event Log

Possible solution

When a

:6Ah

error is generated in the DDE/OPC Communications Event Log (for example,

AB_ETH-1\130.130.130.130: S:42 : 09/26/03 - 13:47:28 : 6Ah

), append an option (

:V4

) to the EtherNet/IP address while configuring an Ethernet driver (AB-ETH) that specifies the driver always uses the legacy CSPV4 protocol for SLC 500 processors. For example,

130.130.130.130:V4
