* BIT-oriented means that one bit is addressed per physical address. WORD-oriented means that one word (16
bits) is addressed per physical address.
** Input of the start address is octal, which means that the number 8 and 9 are invalid characters. The address is
managed internally by decimal point and must be considered for logger and status.
Discrete inputs and outputs are assigned 1 bit in the PLC. During reading and writing they are processed as an 8
bit value. This means that reading and writing of single bits is not supported.
The ranges can be addresses using the above character strings or a number. For example, a discrete input can be
addressed both by E and the number 1.
