The Modem Controller Object is used to control the functions of the NCB Module’s data modem. These
functions include configuration, connection control, and connection status. Two Modem Controller Objects are
available, depending on the NCB model being used. ‘Internal Modem’ is for use with the NCB-IM. ‘External
Modem1’ and ‘External Modem 2’ are for use with the NCB-EM and NCB-IS. All Modem Controller Objects
have identical network variable inputs and outputs.
