The minimum hysteresis between the upper and lower switching

threshold amounts to at least 10% of the lower threshold (logarithmic gauges) or 1% of the full scale value (linear gauges). The upper threshold is if necessary automatically adjusted to a minimum hysteresis. This prevents unstable states.

Measurement value filter

The measurement value filter permits a better evaluation of unstable or disturbed measuring signals.

The measurement value filter does not affect the analog output

(→  22).

FILTER I

FILTER OFF I  No measurement value filter

FILTER FAST I  Fast:

Value

The VGC50x responds quickly to fluctuations in the measurement value. As a result, it will respond faster to interference in the measured values.

Pressure p

FILTER NORMAL I  Normal (factory setting):

FILTER SLOW I  Slow:

Time t

Good relationship between response and sensitivity of the display and the switching function to changes in the measured values.

Pressure p

Time t

The VGC50x does not respond to small changes in measured values. As a result, it will respond more slowly to changes in the measured values.

4.5.6 Data Logger Mode

Parameters in this group

DATA LOGGER >I The data logger group is used for

• recording measurement data on a USB memory stick (interface type A on the front of the Center unit)

• deleting recorded measurement data from the USB memory stick

This group is only available when a USB memory stick formatted for the

FAT file system (FAT32) is plugged in. Use a max. 32 GB memory stick.

Not all USB memory sticks are automatically recognized by the

VGC50x, as they (in particular cheaper brands) do not always conform to USB standard requirements. Try a different memory stick before contacting your nearest INFICON service center.

5 Communication Protocol (Serial Interface)

The VGC50x communicates with a computer via virtual serial interfaces (COM ports). Thus the user software can access the VGC50x via USB Type B or via Ethernet interface.

Communication via USB Type B interface

Communication via Ethernet interface

The corresponding driver for the virtual COM port is installed automatically, when the VGC50x is connected to a computer via the USB Type B interface. If the driver is not installed automatically, it can be downloaded from the FTDI website (www.ftdichip.com/Drivers/VCP.htm).

The installed virtual COM port appears as additional serial interface in the device manager of the computer.

With the Ethernet Configuration Tool a virtual serial interface (COM) can be assigned to an IP address. In addition, it allows configuration of the Ethernet interface via a computer (→  106).

The installed virtual COM port appears as additional serial interface in the device manager of the computer.

When the VGC50x is put into operation, it starts transmitting measured values in intervals of 1 s. As soon as the first character is transferred to the VGC50x, the automatic transmission of measured values stops. After the necessary inquiries or parameter modifications have been made, the transmission of measured values can be started again with the COM command (→  70).

Communication structure and procedures are identical for the three controllers VGC501, VGC502 and VGC503. Therefore the term VGC50x is used in this chapter.

It should be noted that mnemonics with channel specific parameters must be issued with the number of values corresponding to the number of channels of the respective device.

After each ASCII string, the HOST must wait for a report signal (<ACK><CR><LF> or <NAK> <CR><LF>).

The input buffer of the HOST must have a capacity of at least 32 bytes.

Reception protocol

Error processing

Messages are transmitted to the VGC50x as ASCII strings in the form of mnemonic operating codes and parameters. All mnemonics comprise three ASCII characters.

Spaces are ignored. <ETX> (CTRL C) clears the input buffer in the VGC50x.

<––––––––––––––––– <ACK><CR><LF> Positive acknowledgment of a re-

When requested with a mnemonic instruction, the VGC50x transmits the measurement data or parameters as ASCII strings to the HOST.

<ENQ> (CTRL E) must be transmitted to request the transmission of an ASCII string. Additional strings, according to the last selected mnemonic, are read out by repetitive transmission of <ENQ>.

If <ENQ> is received without a valid request, the ERROR word is transmitted.

CPR - Combined pressure

range (linear gauges)

Example

This parameter combines different pressure ranges to one combined pressure range, if several linear gauges with different full scales (F.S.) are connected to the VGC502 and VGC503. Thus the pressure for this combined pressure range can be read out with best accuracy.

The pressure is higher than the full scale of the gauge with lower full scale: The VGC502/503 switches to the gauge with higher full scale.

Only one linear gauge is connected: The measurement value of this gauge is output.

No linear gauge is connected: 1000 mbar is output as measurement value and the parameters a, b and c are set to "0".

Channel 1: linear gauge, 1000 mbar F.S.

Channel 2: linear gauge, 10 mbar F.S.
