The module is now set up and ready to be used with your application. Turn off
the power to the SLC rack and insert the module in the rack and attach the serial
communication cables. Turn on the power to the rack. Download the new
application to the controller and place the processor in run mode. If all the
configuration parameters are set correctly and the module is attached to a serial
network, the module's Application LED (APP LED) should remain off and the
backplane activity LED (BP ACT) should blink rapidly. Refer to the
Troubleshooting
(page 38) section if you encounter errors. Attach a computer
or terminal to the Debug/ Configuration Port on the module and look at the status
of the module using the Configuration/Debug Menu in the module.
2.1 Module Configuration
In order for the MVI46-GSC module to function, a minimum amount of
configuration data must be transferred to the module. The following table
provides an overview of the different types of configuration data that the module
will require, depending on the operating modes to be supported.
Function Name Description
Data
Transfer General Module
Configuration This section of the configuration data contains the module
configuration data that defines the data transfer between the
module and the SLC processor.
Serial Port
Drivers Port Configuration These sections define the characteristics of each of the serial
communication ports on the module. These parameters must
be set correctly for proper module operation.
The MVI46-GSC module must be configured at least once when the card is first
powered, and any time thereafter when the parameters must be changed.
Changing parameters during operation
In order to change any of the module's configuration information, a warm- or
cold-boot operation is required. This will force the module to request the
configuration information from the processor. A warm- or cold-boot request can
be generated by the processor through the ladder logic or through the
Configuration/Debug port of the module.
2.2 Module Data
All data related to the MVI46-GSC is stored in user defined data areas. The user
is responsible for setting up the data areas to match the specific application for
which the module is used. Each data area is discussed below:
2.2.1 Configuration Data
Configuration of the module is performed by filling a user defined data table. In
the example ladder logic, file N10 is used for this purpose. Each item in the file
has an associated symbol and description to aid in filling in the data.
