Using Function Codes
2-371
Function Code: 434E Hex
Function: Writes data to multiple registers specified by a 32-bit address, one point at a time.
Data is written one or two words at a time in registers in the remote station as specified in the
remote station address table that is stored in registers in the local station. This function writes the
number of data items specified by the data size parameter.
The register type and data address that are specified in the remote station address table determine
the registers in the remote station.
The following parameters need to be set in the MSG-SNDE function.
The following example illustrates how the contents of non-consecutive registers are written by using func-
tion code 434E hex. In this example, 2 words of data are read from register IW0002000, 2 words from reg-
ister MW0120000, and 1 word from register SW00200 in the local station. These words are written to
registers MW0001000, GW1000000, and GW2097151 in the remote station. The remote station address
table starts at register GW0001000 and the local station address table starts at register GW0002000 in the
local station.
The remote station address table and local station address table consist of 4 words per data item, as illus-
trated below.
MSG-SNDE Function Parameter Description
PARAM10 Connection Number Set the connection number used to determine the remote station.
PARAM11 Option Not used.
PARAM12 Function Code Set the function code for the function to use.
PARAM14

Address, Lower Word
Set the first register address where the remote station address table is
stored.
PARAM15
Remote Station Data
Address, Upper Word
PARAM16
Remote Station Register
Type
Set the register type (M or G) in the local station where the remote sta-
tion address table is stored.
PARAM17 Data Size Set the number of data items to write.
PARAM18
Remote CPU Module
Number
This parameter is used with the Extended MEMOBUS protocol. Set the
CPU number at the remote station.
PARAM20
Local Station Data
Address, Lower Word
Set the register address that points to the first address of the local sta-
tion address table that lists where the data to be written is stored.
PARAM21
Local Station Data
Address, Upper Word
PARAM22
Local Station Register
Type
Set the register type (M or G) in the local station where the local station
address table is stored.
PARAM24 For system use
Set this parameter to 0 from a user program or by other means in the
first scan after the power is turned ON. Thereafter, do not change the
value of this parameter. This parameter is used by the system.
