Sets the device's analog configuration.
- Parameters
-
[in] | handle | Valid handle returned by SM_Open(). |
[in] | reference | Analog to digital reference point. |
[in] | mode | Device input mode. |
- Return values
-
0 | Successful completion. |
-1 | Invalid SeaMAX handle. |
-2 | Error retrieving the mode configuration. |
-3 | Connection is not established. Check the provided Connection object state. |
-4 | Modbus: Read error waiting for response. Unknown Modbus exception. |
-5 | Modbus: Illegal Modbus Function (Modbus Exception 0x01). |
-6 | Modbus: Illegal Data Address (Modbus Exception 0x02). |
-7 | Modbus: Illegal Data Value (Modbus Exception 0x03). |
-8 | Modbus: CRC was invalid. Possible communications problem. |
-9 | Invalid device configuration. |
Sets the I/O device's offset reference and A/D channel mode. The reference parameter determines which source each analog input is compared against. The mode parameter determines the overall configuration of the channels and whether they are singled ended or paired.
- Note
- The reference parameter for almost all purposes should be set to ANALOG. This is the normal reference point for single ended, differential, and current mode applications. Other reference points have been included as diagnostic tools or references for calibration.
For more information on the appropriate values, see A/D Voltage Reference values and A/D Channel Modes.
- Note
- This method only applies to certain models. See SeaMAX by Sealevel Model Number for details.
