Parameter:
| Parameter | Statement | Type | Description |
|---|---|---|---|
| IN | Input | BOOL/BYTE/WORD/DWORD/INT/SINT/DINT/UINT/USINT/UDINT/REAL/TIME/STRING | The first input value |
| MN | Input | BOOL/BYTE/WORD/DWORD/INT/SINT/DINT/UINT/USINT/UDINT/REAL/TIME/STRING | The second input value |
| MX | Input | BOOL/BYTE/WORD/DWORD/INT/SINT/DINT/UINT/USINT/UDINT/REAL/TIME/STRING | Third, enter the value |
| OUT | Output | BOOL/BYTE/WORD/DWORD/INT/SINT/DINT/UINT/USINT/UDINT/REAL/TIME/STRING | Output value |

Interpretation:
| parameter | operand | value |
|---|---|---|
| IN1 | TagIn | Enter a value：100 |
| MN | TagMn | Enter a value：50 |
| MX | TagMx | Enter a value：200 |
| OUT | TagOut | Output value：100 |
IN1, MN, and MX input the corresponding type of data, and LIMIT outputs the limiting value.
