.BIT
It can only be used in non-bit type area, which means to read the specified bit of the specified address, and the binary bit index range is [0, 15].
| Address | Data Type | Description |
|---|---|---|
| D20.0 | bit | D area, address is 20, bit 0 |
| D20.2 | bit | D area, address is 20, bit 2 |
.LEN[H][L]
When the data type is string, .LEN indicates the length of the string; H and L can be optional to indicate two byte orders, the default is H byte order.
Address Examples
| Address | Data Type | Description |
|---|---|---|
| X0 | bit | X area, address is 0 |
| X1 | bit | X area, address is 1 |
| Y0 | bit | Y area, address is 0 |
| Y1 | bit | Y area, address is 1 |
| D100 | int16 | D area, address is 100 |
