2 Supported Device Addresses
The following table lists the device address ranges you can enter from the Device Address
keypad. For actual device address ranges supported by the PLC, refer to the corresponding PLC
manual
Supported device addresses differ from protocol to protocol and between PLC models.

*1 To use as word address, the bit number (last digit) must be 0.
*2 To use as word address, must be multiple of 16.
*3 When the bit write operation is performed, the Target Machine reads the PLC’s
corresponding word address and turns a bit ON, then send back to PLC. Do not write to the
word address from the ladder program in the middle of this operation.
*4 You can define a bit address by adding a colon followed by the bit position (0~15) at the end
of the word. (e.g. D0000:15)
*5 You can define a bit address by adding a colon followed by the bit position (0~F) at the end
of the word. (e.g. W0000:F)
