The analog I/O module defines the I/O range, customizable values, fallback mode, and fallback value.

Analog channels can be mixed.
| Channel | Object (Hex) | Sub index | Description | Parameter | 
| CH1 (Input) | 2100 | n | Data Type | 0: Unused 2: Current (4 to 20mA) 3: Voltage (0 to 10V) | 
| 2101 | n | Data range | 0: Fixed 1: User setting | |
| 2102 | n | Lower limit When 2101 is 1 Converts input data within the range between the analog input lower limit and the analog input upper limit. When 2101 is not 1 Converts to a fixed value depending on the settings of 2100 and 2101. You can set up the abnormal input range in the Analog Input Lower Limit and Analog Input Upper Limit fields. | Lowest value | |
| 2103 | n | Upper limit When 2101 is 1 Converts input data within the range between the analog input lower limit and the analog input upper limit. When 2101 is not 1 Converts to a fixed value depending on the settings of 2100 and 2101. You can set up the abnormal input range in the Analog Input Lower Limit and Analog Input Upper Limit fields. | Highest value | |
| 6401 | n | Read value | Input | |
| 6421 | n | PDO transmission trigger | Enable/disable PDO Transmission for each bit state. 0: Disable PDO transmission 1: Enable PDO transmission 
 Bit 0: Greater than analog input upper threshold value Bit 1: Less than analog input lower threshold value | |
| 6422 | 1 | PDO transmission channel number | Indicates the channel in which active bit caused an event. | |
| 6423 | 0 | PDO transmission enabled/disabled | 0: Disable PDO transmission 1: Enable PDO transmission | |
| 6424 | n | Top threshold | Top threshold value | |
| 6425 | n | Bottom threshold | Bottom threshold value | |
| CH2 (Input) | Same as CH1 (Input). Sub index is n+1. | |||

| CH4 (Input) | Same as CH1 (Input). Sub index is n+3. | |||
| CH1 (Output) | 2200 | n | Data Type | 0: Unused 2: Current (4 to 20mA) 3: Voltage (0 to 10V) | 
| 2201 | n | Data range | 0: Fixed 1: User setting | |
| 2202 | n | Lower limit When 2101 is 1 Converts output data within the range between the analog output lower limit and the analog output upper limit. When 2101 is not 1 Converts to a fixed value depending on the settings of 2100 and 2101. You can configure the abnormal output range in the Analog Output Lower Limit and Analog Output Upper Limit fields. | Lowest value | |
| 2203 | n | Upper limit When 2101 is 1 Converts output data within the range between the analog output lower limit and the analog output upper limit. When 2101 is not 1 Converts to a fixed value depending on the settings of 2100 and 2101. You can configure the abnormal output range in the Analog Output Lower Limit and Analog Output Upper Limit fields. | Highest value | |
| 6411 | n | Written value | Output | |
| 6443 | n | Fallback mode | 0: Retentive State 1: Fallback | |
| 6444 | n | Fallback Value (when 6443h = 1) | Fallback Value | |
| CH2 (Output) | Same as CH1 (Output). Sub index is n+1. | |||
