This is used for PLCs that are connected to the CIMPLICITY host computer through a PI Gateway. The connection between the PI Gateway and CIMPLICITY software is through Ethernet, and PLCs are connected to the Gateway through a Data Highway Plus network. The unsolicited messages are sent locally on DH+ to the EI module of the PI Gateway. The piunsol.ini file must be configured on the host computer to receive unsolicited messages from the PI Gateway.
