Not recoverable by the end user:
[d] 0 = no error;
[d] 1 = display error;
[d] 2 = data-storage error;
[d] 3 = error 1 + error 2 simultaneously;
[d] 4 =: initialization error.
[d] 8 =: Analog input error;
[d] 16 =: PT100 ADC error
.
Recoverable by the end user:
[d] 32 =: Correction calculation factor (A) error;
[d] 64 =: Correction calculation factor (B) error;
[d] 128 =: Temperature Pressure Compensation (TPC A) calculation error;
[d] 256 =: Temperature Pressure Compensation (TPC B) calculation error;
[d] 512 =: PT100 sensor 1 out of range error;
[d] 1024 =: PT100 sensor 2 out of range error.
For a not recoverable error, keep the error code at hand and contact your
supplier.
10. Communication
General
The product is fitted with the Modbus communication protocol and can be
equipped with various physical interfaces like RS485 (please see device
datasheet for available options). The tables below show the various variables that
can be accessed through the communication.
Currently, the function codes supported are:
function code 3 “Read Holding Registers” (4x references);
function code 16 “Preset Multiple Registers” (4x references).
The table below shows the Modbus PDU addresses in a decimal format, followed
by its hexadecimal representation (0x0000). When the PLC address range is
required (4x references are typically used by PLCs), please add a value of 40001
to the Modbus PDU address. E.g. reading the serial number of the product with
PLC-based addressing means: 165 + 40001 = register 40166.
