Note The WORD BLOCK DATA READ/WRITE commands with an unspecified
node numbers are provided to ensure compatibility with applications created
with the CS1W-FLN01. Use the WORD BLOCK DATA READ/WRITE com-
mands with specified node numbers to create new applications.
Response codes are 2-byte codes that indicate the results of command exe-
cution. They are returned in the response following the command code.
The first byte of a response code is the MRES (main response code), which
categorizes the results of command execution. The second byte is the SRES
(sub-response code) which specifies the results.
The relationship between the MRES and the execution results are shown in
the table on the next page.
