11. Serial interface
The device features one EASYBus-Interface. You can use the device as a full function EASYBus-
device.
The serial interface allows the device to communicate with a host computer. Data polling and data
transfer is done in master/slave mode, so the device will only send data on demand. Every device
has a unique ID-number that makes exact identification of each device possible. With the help of a
software (like EASYBus-Configurator
– freeware version available via internet) you are able to re-
assign an address to the device.
Additional accessories needed for the interface mode:
- Interface converter EASYBus
PC:
e.g. EBW1, EBW3, EBW64
- Software for communication with the device
EBS20M / 60M: 20-/60-channel-software for displaying a measured value.
EASYControl net: universal multi-channel software for real-time-recording and displaying meas-
ure-values of a device in ACCESS®-database-format.
EASYBUS-DLL: EASYBUS-developer-package for developing own software. This package fea-
tures a universal WINDOWS®-Library with documentation and program-
examples. The DLL can be used in any usual programming language.
12. Error codes
When detecting an operating state which is not permissible, the device will display an error code.
The following error codes are defined:
Err.1:
Exceeding of the measuring range
Indicates that the valid measuring range of the device has been exceeded.
Possible causes:
- Input signal to high.
- Sensor broken (Pt100 and Pt1000).
- Sensor shorted (0(4)-20mA).
- Counter overflow.
Remedies:
- The error-message will be reset if the input signal is within the limits.
- check sensor, transducer or transmitter.
- check device configuration (e.g. input signal)
- reset the counter.
Err.2:
Values below the measuring range
Indicates that the values are below the valid measuring range of the device.
Possible causes:
- Input signal is to low or negative.
- Current below 4mA.
- Sensor shorted (Pt100 and Pt1000).
- Sensor broken (4-20mA).
- Counter underflow.
Remedies:
- The error-message will be reset if the input signal is within the limits.
- Check sensor, transducer or transmitter.
- check device configuration (e.g. input signal)
- Reset the counter.
Err.3:
Display range has been exceeded
Indicates that the valid display range (9999 digit) of the device has been exceeded.
Possible causes:
- Incorrect scale.
- Counter overflow.
Remedies:
- The error-message will be reset if the display value is below 9999.
- Reset the counter.
- When happening frequently, check the scale-setting, maybe it was set
too high and should be reduced.
