Address L, Address H (Command)
The address in hexadecimal of the first word of data to be read.
Address L: Rightmost 2 digits of the address in 4-digit hexadecimal.
Address H: Leftmost 2 digits of the address in 4-digit hexadecimal.
When specifying a Holding Area word (H100 or H102 to H127) in a CS1H/G
PLC, specify the first word in hexadecimal with 0000 Hex for H100 or 0002 to
001B Hex for H102 to H127.
No. of read words (Command)
The number of words of read data, in single-byte (2-digit) hexadecimal. The
specified range is 01 to 64 Hex (1 to 100 in decimal).
No. of received bytes (Response)
The number of bytes received from the destination node address is returned
in hexadecimal.
Source node address (Response)
The node address of the C200H I/O Link Unit that returned the response is
returned in hexadecimal.
Read data (Response)
The specified area type, words, and number of bytes of data are returned
from word L (rightmost byte: bits 0 to 7) to word H (leftmost byte: bits 8 to 15).
Note Actual addresses for Address H and Address L and actual number of bytes to
be read differ according to the model of PLC to which the C200H I/O Link Unit
is mounted and the memory area. Be sure to specify data bytes within the
data area range.
WORD DATA WRITE will write data to any area of the CPU Unit of the PLC to
which the C200H I/O Link Unit is mounted. Write data is specified from the
rightmost byte to the leftmost byte.
