The “Parameters, Divider, Unit” register contains 0x0F99 (3993) if the register is not set by the Modbus master.
Output data (output read by an external Modbus master)
The external Modbus master reads from these slave display registers:
POINT1
Reg1000
Info
Reg1001
Value (16 highest bits)
Reg1002
Value (16 lowest bits)
POINT2
Reg1003
Reg1004
Reg1005
POINT3
Reg1006
Reg1007
Reg1008
…
POINT250 Reg1747
Info
Reg1748
Value (16 highest bits)
Reg1749
Value (16 lowest bits)
The “Info” register contains 0 if the value is not set from the display and 1 if the value set from the display.
The FX-RP multiDISPLAY resets this back to 0 if the value is equal in both input and output register sections.
This register also works as a “lock” to the point value registers, meaning that as long as the info register contains
“1”, the local value will be shown, and the value the Modbus master may be writing into registers 1+2, 4+5, …
is ignored, unless of course you are setting the seventh bit of the “Parameters, Divider, Unit” register.
