Data processing precautions
Numeric data values (Remote register) obtained via communication with the COM-JC and
processed by PLC include those with and without decimal points and also those with minus signs.
•
For numeric data value without decimal point
If there is no decimal point the value is processed as it is.
•
For numeric data value with decimal point
The decimal point is omitted.
[Example] When the measured value (PV) is 120.5
°
C
Read value of remote register (RWrn) [Measured value (PV)]:
1205 (Hexadecimal number: 04B5H)
•
For numeric data value with minus sign
The value is expressed as a 2
’
s complement value which is obtained by subtracting the
minus value from the hexadecimal number 10000H.
[Example] When the measured value (PV) is
−
2.5
°
C
Read value of remote register (RWrn) [Measured value (PV)]:
Hexadecimal number: FFE7H
(10000H
−
25 = 10000H
−
19H = FFE7H)
When a Z-DIO module is connected, execute “Automatic acquisition of controller
address” initially. If “Address setting of connected controller” is left at the factory set
value, it may not be possible to use the data of the Z-DIO module.
