The CIPOpen instruction opens a CIP class 3 connection (Large_Forward_Open) with a remote node
on a CIP network. The remote node is specified with route path RoutePath. The data length is set to
1,994 bytes. The handle Handle is output when the connection is open.
TimeOut specifies the connection timeout time. If a response does not return from the remote node
within the connection timeout time after the CIPSend, CIPWrite, or CIPRead instruction is executed, it
is assumed that communications failed. The connection timeout time is reset when the CIPRead, CIP-
Write, or CIPSend instruction is executed and the remote node returns a response.
