Panel Error
Code
P499 Hex Value
Meaning
0x0001
The function code received in the query is not an allowable action for the server (or slave). This may be because
the function code is only applicable to newer devices and was not implemented in the unit selected. It could also
indicate that the server (or slave) is in the wrong state to process a request of this type, for example because it is
unconfigured and is being asked to return registered values.
0x0002
Address out of range. Check to make sure that the
C-more
Micro Graphic tag and System ID match the
Productivity3000 Programming Software Tag Name and System ID. The project file in the Productivity3000
system and the imported CSV into
C-more
Micro Graphic must be in sync with each other.
0x0003
A value contained in the query data field is not an allowable value for the server (or slave). This indicates a fault
in the structure of the remainder of a complex request, such as that the implied length is incorrect. It specifically
does
NOT
mean that a data item submitted for storage in a register has a value outside the expectation of the
application program, since the Modbus protocol is unaware of the significance of any particular value of any
particular register.
0x0004
An unrecoverable error occurred while the server (or slave) was attempting to perform the requested action.
