.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].

AddressData TypeDescription
D20.0bitD area, address is 20, bit 0
D20.2bitD 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.
