2.15 Using Message Functions
Using Function Codes
2-368
Function Codes: 4345, 4346, 434B, and 434F Hex
Function: Writes data to a data address in the remote station specified by a 32-bit address.
The specified size of data is read from registers in the local station and written to specified registers
in the remote station.
The following parameters need to be set in the MSG-SNDE function.
The following example illustrates how the states of multiple bits are changed by using function code 434F
hex. In this example, 5,000 bits of data starting from register IB120000 in the local station are written to
registers starting at GB02000008 in the remote station.
If the output register offset parameters in the MSG-RCVE function are set to a non-zero value, the
actual addresses that are read in the remote station will be the sum of the remote station data addresses
and the value in the output register offset parameters.
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
Remote Station Data
Address, Lower Word
Set the first address to write to in the remote station. Specify a bit
address for function code 4345 or 434F hex, and a word address for
function code 4346 or 434B hex.
PARAM15
Remote Station Data
Address, Upper Word
PARAM16
Remote Station Register
Type
Set the register type (M, G, O, or S) to write to in the remote station.
PARAM17 Data Size
Set the size of the data to write. Specify the size in bits for function
code 434F hex, and in words for function code 434B hex. This parame-
ter is not used for function codes 4345 and 4346 hex.
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 first register address in the local station where the data to be
written is stored. Specify a bit address for function code 4345 or 434F
hex, and a word address for function code 4346 or 434B hex.
PARAM21
Local Station Data
Address, Upper Word
PARAM22
Local Station Register
Type
Set the register type (M, G, I, O, or S) of the data to be written that is
stored in the local station.
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.
