22. Handling Remote Registers
There are 1-bit data, 1-byte data, 1-word data, or 2-word data assigned to the remote registers (RWr and
RWw), depending on the data content.
22.1 Relationship of bit data, byte data, and word data
The following describes the relationship of each bit data, byte data, and word data for the LECPMJ.
● 1-bit data
This indicates the OFF state (0) and ON state (1) by using one of the two types of data, "0" or "1".
It is used to specify signal ON / OFF outputs such as RWr0,bit3: Sending completed, as well as signal
input instructions such as the RWw0,bit0: Read numerical data flag.
● 1-byte data
A group of eight 1-bit data items.
This indicates 0 to 255 data as an 8-digit binary number.
It is used to output an alarm code such as RWr7: Alarm.
● 1-word data
A group of 16 1-bit data or two 1-byte data.
This indicates the ON/OFF state of 16 types of signals or 0 to 65,535 data as a 16-digit binary number.
It is used to output numerical data by using RWr3: Current speed, etc. as well as input numerical data by
using RWw2: Speed, etc.
● 2-word data
A group of two 1-word data.
This indicates 0 to 2,147,483,647 data as a 32 - digit binary number or -2,147,483,647 to -1 data as a
complement to 2.
It is used to output numerical data by using RWr1 - RWr2: Current position, etc. or input numerical data
by using RWw3 - RWw4: Target position, etc.
