• Registers corresponding to models with the /M1 computation function option.
• Pen model: C01 to C08; Dot model: C01 to C12 (µR10000), C01 to C24 (µR20000)
• The data is a floating point.
• When writing to the register: The values that can be input are −9.9999E29 to −1E−30, 0,
and 1E−30 to 9.9999E29.
If a value exceeding this range is input, a computation error will occur when using the value
on computation channels.
The recorder returns the following error codes to the master device. For the error
messages related to communications that the recorder displays, see appendix 4.
Code Meaning
1 Bad function code
2 Bad register number
3 Bad number of registers
However, no response is returned for the following cases.
• CRC error
• Errors other than those in the table above.
3.4 Modbus Slave Specifications
(From previous page)
Cause
Unsupported function request.
Attempted to read/write to a register that
has no corresponding channel.
The specified number of registers is less
than or equal to 0 or greater than or
equal to 126 (when reading)/124 (when
writing).
