Data Highway Plus

Use this when the host computer has an KT (or KTx) card and the RSLinx driver (AB_KT) has been configured for this card. The unsolicited messages are sent locally on DH+ to the CIMPLICITY host computer. The configuration of unsolicited messages in this case is the same as described in Ethernet through PI Gateway. The only differences are:

The piunsol.ini configuration is not required on host.

The DH+ node address of the CIMPLICITY host is entered under local node address.
