-->DELPHI PROGRAMMING EXAMPLES CAN'T BE COMPILED (B1004)

The DELPHI programming examples cannot be compiled, although the ActiveX component BMCSAD has been installed properly. This only happenswhen using DELPHI® 3.01, DELPHI® 3.02, DELPHI® 4.x and DELPHI® 5.x.

With the Maintenance Release 1 the import function of DELPHI® has changed considerably. The recent versions of DELPHI (and the command-line version tlibimp.exe) produce completely different header files than DELPHI® 3.0. Basically these header files are suitable to call the functions of the BMCSAD, but are much too complicated to handle. Therefore we recommend to use the header files of DELPHI® 3.0.

-->-->Details and suggested solutions

 

 

-->ACTIVEX IMPORT IN DELPHI® DOES NOT WORK (B1005)

The ActiveX import in DELPHI® 6 shows wrong properties/functions in the respective TLB-file. That means that programs using these ActiveX functions cannot be compiled.

-->-->Details and suggested solutions

 

 

-->WRONG NAME FOR MEM-ADFO IN LABVIEW™ VI (LV1006)

The documentaton of the LabVIEW™ VI 'bmcOpen.vi' declares a wrong name for meM-ADfo. This name is also used by the VI 'bmcCheckName.vi'. The device meM-ADfo cannot be opened if in 'bmcOpen.vi' the 'Cardname' memadfousb is entered as described in the documentation.

-->-->Details and suggested solutions

 

 

-->SCALING CURRENT SIGNALS WITH MA-UI (MA1001)

For sensors with ± measuring range and current output (0-20mA) it is recommended to use the mid-position (10mA) for zero-adjustment.

-->-->Details and suggested solutions

 

 

-->SCALING CURRENT SIGNALS WITH MA-UI AND MA-UNI (MA1002)

Sometimes only the relatively small changes of a measuring signal are to be sampled without loss of resolution.
Example: The zero position of a measuring signal is +5V and the amplitude ±1V (4-6V).

-->-->Details and suggested solutions

 

 

-->PT100 LINEARIZATION WITH MA-UNI (MA1003)

When using a PT100 temperature sensor in combination with the universal measuring amplifier MA-UNI from BMC Messsysteme GmbH, which amplifies but does not linearize the measured signal, a formula must be applied to determine the temperature values.

-->-->Details and suggested solutions

 

 

-->CONNECTING ACTIVE 24V SENSORS TO MA-UI AND MA-U (MA1004)

Active sensors are often supplied with 24V DC (15-30V). For electrical isolation of the sensor supply and the sensor signal the measuring amplifier MA-UI or MA-U can be used.

-->-->Details and suggested solutions

 

 

-->THERMOCOUPLE (TYPE K) LINEARISATION (MAL1001)

When using a thermocouple (type K) in combination with the measuring amplifiers from BMC Messsysteme GmbH (MAL, MVL, MA-UNI, MA-UI), which amplify but do not linearize the measured signals, a formula must be applied to determine the temperature values.

-->-->Details and suggested solutions

 

-->USING THE MEM ACTIVEX CONTROL IN TESTPOINT™ (MEM1000)

Until now direct communication with the meM-devices via the accompanying ActiveX Control was not possible together with the measuring data acquisition software TestPoint™ (Keithley®). The meM-devices however can still be used. This does not apply to the latest version. Here the meM-devices are reached directly via the ActiveX Control.

-->-->Details and suggested solutions

 

 

-->VOLTAGE EXTENSION FOR MEM DEVICES (MEM1001)

-->CHANGES WITH THE SOFTWARE COLLECTION 4.x CONCERNING NEXTVIEW®4 (NV41000)

Version 4.5 of the Software Collection from BMC Messsysteme GmbH has been released in November 2011 replacing all previous versions. This includes the latest version of NextView®4, the software for data acquisition and processing. Especially if changing from NextView®/NT to NextView®4 (in the following: NV4 and NVNT), please note the following information.

-->-->Details and suggested solutions

 

 

-->CHANGE LANGUAGE IN NEXTVIEW®4 (NV41001)

The professional software for measurement data acquisition and processing NextView®4 is provided in German and English. Changing the language does not require to reinstall the software.

-->-->Details and suggested solutions

 

 

-->BMCM SOFTWARE COLLECTION UNDER WINDOWS® 7 (NV41002)

This FAQ discusses questions resulting from changing to Windows® 7 as well as the subjects 32-bit or 64-bit version, driver signing and driver certification and describes the consequences for drivers and software from BMC Messsysteme (software version up to 4.3).

-->-->Details and suggested solutions

 

 

-->REQUEST NEXTVIEW®4 LICENSE NUMBER WITH OUTLOOK (NV41003)

When applying for a NextView®4.5 license number via email, users of the email program Outlook receive the error message "None of your email accounts could send to this recipient".

-->-->Details and suggested solutions

 

 

-->SPIKE WHEN INITIALIZING (OR1000)

When using the OR8 or R8 in connection with the digital I/O card PIO24II and PIO48II supplied with Harris components, the relays may turn on for a short moment when initializing the PC. This is characteristic for that component.

-->-->Details and suggested solutions

 

 

-->PIN ASSIGNMENT OF THE SUB-D SOCKETS OF PIO AND PIO-II (PIO1000)

The latest version of the PIO card has one (PIO24II) or two (PIO48II) 25-pole D-Sub socket(s) instead of the 50-pole D-Sub used so far.

The PIO card provides for 48 channels for the acquisition and control of TTL signals. The 48 port lines are led out via a 50-pole D-Sub socket in the PC card bracket. The other two pins are for the connection to ground. PIO-II on the other hand is available as PIO24II with 24 channels or as PIO48II with 48 channels. The 24 or 48 channels can be reached via one or two 25-pole D-Sub sockets. Pin 25 at each socket is the connection to ground.

Therefore if switching to another PIO type the pin assignment is different.

-->-->Details and suggested solutions

 

 

-->CONNECTING SEVERAL O8/R8/OR8 TO A PIO-II CARD (PIO1001)

The connection of an optocoupler or relay card to a PIO-II is realized with a plain 25-pole D-Sub extension cable to the 25-pole D-Sub socket of the PIO-II. It is also possible to connect two O8/R8/OR8 directly to the PIO48II, as it provides for two 25-pole D-Sub sockets. When using several O8/R8/OR8, a special connection cable must be made. In this case, check for the correct pin assignment.

-->-->Details and suggested solutions

 

 

-->INTERFACING EXAMPLES OF AN INPUT LINE TO THE PIO-II CARD (PIO1002)

The accompanying PDF shows several examples how to connect an input line to the PIO-II giving you useful advices about common sources of errors and a programming example in Visual Basic®, Visual C++ and Delphi®.

In consideration of hardware dependant differences and if using the corresponding programming variable, the examples can be applied to all bmcm measuring systems with digital inputs.

-->-->Details and suggested solutions

 

 

-->INTERFACING EXAMPLES OF AN OUTPUT LINE TO THE PIO-II CARD (PIO1003)

The accompanying PDF shows several examples how to connect an output line to the PIO-II giving you useful advices about common sources of errors and a programming example in Visual Basic®, Visual C++ and Delphi®.

In consideration of hardware dependant differences and if using the corresponding programming variable, the examples can be applied to all bmcm measuring systems with digital outputs.

-->-->Details and suggested solutions

 

 

-->ALL INPUTS ON HIGH WHEN TURNING ON (PIO1004)

When turning on the PC, all inputs of the ISA measuring card (also: PC104) are high. Some channels change between low and high.

-->-->Details and suggested solutions

 

 

-->USING AND PROGRAMMING PIO/PIO-II CARDS ON WINDOWS® (PIO1005)

Initially the digital I/O cards PIO and PIO-II were only programmable on MS-DOS. As today Windows® is the commonly used operating system drivers and software has been developed making use and programming of the PIO and PIO-II also possible on Windows®.

-->-->Details and suggested solutions

 

 

-->INITIALISING ALL PORTS WHEN CHANGING THE DIRECTION (PIO1006)

Changing the direction of a digital port of a PIO/PIO24II/PIO48II between in- and output initializes also channels that do not belong to the respective port. E.g. all outputs are set to 0. However, this does not concern all channels of the PIO and PIO48II. The problem only occurs when programming the digital interface cards on MS-DOS.

-->-->Details and suggested solutions

 

 

-->REACTION OF THE PIO DEVICES WHEN TURNING ON THE PC (PIO1007)

If the PIO, PIO24II, PIO48II is supplied with the PIO component CP82C55 from Harris, it switches the port lines during a resets to input and sets them with the included pullup resistors high-ohmic on high. The consequence is that after starting the PC connected relays turn on. The same reaction can happen when using the meM-PIO or USB-PIO.

-->-->Details and suggested solutions
