H.18 Supported Modbus Data types
Modbus Data types are not standard. Based on the analysis of the
Modbus field devices, the following Modbus data types would be
supported in CIU.
Modbus Data
Type
Not a number
Fixed number
ASCII string
Unicode string
16-bit unsigned
integer
16-bit signed
integer
Configuration Manual
CIU 888
Description
This value indicates the
portion in the CIU parameter
where the device value needs
to be copied.
For example, if the device
value needs to copied to Bits
12 to Bit 8 after value mapping
is done then it BitM = 8 and
BitN = 12
If the the device value (after
value mapping) needs to
completely replace CIU
parameter value then this tag
shall be empty.
Device Value in Modbus data
type.
CIU Value in CIU Parameter
data type.
This data represents 8 / 16 bit coded information.
This data represents a 16 bit fixed number.
The data represents a string of two ASCII characters per
register.
The data represents a string of one UNICODE character per
register
The data represents an unsigned integer.
Range : 0 to 65535
The data represents an signed integer (in 2's complement).
Range : -32768 to 32767
