- The "−" symbols in the table mean that the bit is reserved and always zero.
- Coil addresses are 0 to 79, calculated by subtracting one from coil numbers. If a coil address
is 80 or more, an error occurs because of an incorrect address.
- The number of coils is 1 to 80. If the number of coils exceeds the range, an error occurs
because of an incorrect address.
- No error occurs even if the sum of the numbers of coil addresses and coils exceeds the coil
range.
