Retrieves the A/D configuration for a Sealevel I/O module.
- Deprecated:
- Version 3.0.4
- Parameters
-
| [in] | handle | Valid handle returned by SM_Open(). |
| [out] | deviceConfig | Configuration of the module. |
| [out] | channelsConfig | A/D channels' voltage ranges. |
- Return values
-
| 0 | Success. |
| -1 | Invalid SeaMAX handle. |
| -2 | Connection is not established. Check the provided Connection object state. |
| -3 | Read error waiting for response. Unknown Modbus exception. |
| -4 | Illegal Modbus Function (Modbus Exception 0x01). |
| -5 | Illegal Data Address (Modbus Exception 0x02). |
| -6 | Illegal Data Value (Modbus Exception 0x03). |
| -7 | Modbus CRC was invalid. Possible communications problem. |
- Note
- This function has been replaced by SM_GetAnalogInputConfig() and SM_GetAnalogInputRanges(). See the updated function for parameter and return values.
Retrieves the module's offset reference, A/D mode, and channel ranges. The deviceConfig parameter will contain two bytes: deviceConfig[0] containing the analog reference point (should be zero for most applications), and deviceConfig[1] containing the A/D channel mode. The channelsConfig parameter will contain one byte for every analog input, indicating that input's channel range (e.g., channelsConfig[4] indicates analog input 5's channel range).
For more information on the appropriate bit values, see A/D Voltage Reference values, A/D Channel Modes, and A/D Channel Range values.
- Warning
- The parameter deviceConfig should have at least 2 bytes, and channelsConfig should have at least 16 bytes, allocated before calling SM_GetADDAConfig().
