(2) Basic parameter areas
These areas are used to set the basic parameters required for cyclic communications. Be sure to
set values in all the areas without omissions. If a certain area is left undefined (e.g., a setting of
0 is employed), a parameter setting error may occur.
Register
number
Area name Area description Remarks
BD008 Status display/control register
address Y, Q, R, M, K, G, and E registers *1
BD009 Communication response wait
time (ms) 50 to 10,000 ms (Digits below 10 are
cut off.)
BD00A Cyclic communication retry
count
0 to 10
BD00B Reserved for future use To be fixed at 0.
BD00C Cyclic communication protocol
setting
To be fixed at 0.
BD00D MELSEC side IP address Any setting (in hexadecimal notation) *2
BD00E Communication data endian
conversion 0: endian conversion effected; 1: no
endian conversion *3
BD00F Reserved for future use To be fixed at 0.
*1 When an error occurs, the specified register bit is set. This ensures that the error is detected by a
ladder program. All the registers outside the acceptable setting range are in setting error. For
the assignments for the registers, see under "Status display/control register assignments" (next
page). For the setup procedure, see item (6).
*2 Enter a hexadecimal number to specify the IP address of the MELSEC, which is the remote station
to communicate with.
Example: When the IP address of MELSEC is 162.0.9.194, the setting is HA20009C2 because 162
= HA2, 0 = H00, 9 = H09, and 194 = HC2.
*3 Only the bit areas can be subjected to endian conversion between big endian and little endian.
Word areas will not be subjected to endian conversion even if the endian conversion option is
enabled.
