8. A direct connection is a real time data transfer link between the controller and the device that occupies the slot that the configuration data references When module configuration data is downloaded to an owner controller the controller attempts to establish a direct connection to each of the modules referenced by the data One of the following events occurs e If the data is appropriate to the module found in the slot a connection is made and operation begins e If the configuration data is not appropriate the data is rejected and an error message displays in the software In this case the configuration data can be inappropriate for any of a number of reasons For example a module s configuration data may be appropriate except for a mismatch in electronic keying that prevents normal operation The controller maintains and monitors its connection with a module Any break in the connection such as removal of the module from the chassis while under power causes the controller to set fault status bits in the data area associated with the module The RSLogix 5000 software may monitor this data area to announce the modules failures In traditional industrial applications controllers poll counter modules to obtain their status Controllers also send commands to the counter modules Retrieving counter status and sending commands occurs during the normal I O program scan ControlLogix HSC modules do not follow the traditional operatio
