9.7 Send Message Function (MSG-SND)
9-20
0DH Discontinuous readout of holding register
(expanded) 1 to 508
(1 to 01FCH) words 1 to 252
(1 to 00FCH) words
0EH Discontinuous write into holding register
(expanded) 1 to 254
(1 to 01FEH) words 1 to 126
(1 to 007EH) words
0FH Change status of a multiple coil 1 to 800 (1 to 0320H) bits
10H Write into a plurality of holding register 1 to 100 (1 to 0064H) words
■ Called CPU # (PARAM07)
Set the called CPU No.
■ Coil Offset (PARAM08)
Set the offset word address of the coil. This is valid in the case of function codes 01H, 05H, and
0FH.
■ Input Relay Offset (PARAM09)
Set the offset word address of the input relay. This is valid in the case of function code 02H.
■ Input Register Offset (PARAM10)
Set the offset word address of the input register. This is valid in the case of function codes 04H
and 0AH.
■ Holding Register Offset (PARAM11)
Set the offset word address of the holding register. This is valid in the case of function codes
03H, 06H, 09H, 0BH, 0DH, 0EH, and 10H.
■ For System Use (PARAM12)
The channel No. being used is stored. Make sure that this will be set to 0000H by the user
program on the first scan after turning on the power. This parameter must not be changed by the
user program thereafter since this parameter will then be used by the system.
■ Relationship between the Data Address, Size and Offset
Relationship between the data address, size and offset are described Figure 9.10.

■ When transmission protocol is set to non-procedural
The setting of PARAM04, PARAM08, PARAM09, and PARAM10 are not necessary.
Transmission enabled register is only MW.
