3.4.6 Modbus to SMS
InGateway inquires the variables status of the PLC every ten seconds and saves them into RAM.
These variables will be the SMS response sent after a query. After receiving a control SMS, InGateway
sends the control command to the PLC and waits for a response. The response is sent from the PLC and
then InGateway sends the response to the user.
To enable SMS, find the navigation panel, select
