requirements, click Apply Setup transmit the new settings.
Scan the Module Data Values
After the module has been properly configured, the analog input module configuration dialog
boxes can poll the module to verify the data from each channel. This feature is a troubleshooting
or verification tool when the analog input signals are physically connected to the module.
The analog input dialog box contains a Scan function to start the scanning process. Each data
channel is read by requesting the data values from data registers within the module. The analog
input data registers are included in the Modbus Register map and the data register locations
are specific to the module.
The data values are returned in hexadecimal percentage of Full Scale format where a value
of 0x0000 represents the minus full scale input of the module. A value of 0xffff represents the
positive full scale input of the module. These values can be used as a check to ensure that the
channels are operating properly when analog input signals are applied to the input terminals.
