For passive probes (for example P50 and AP57*) data is printed when a signal is
detected above
Reject Level or when the print button is pressed. Activate this under
Measure Button menu.
For active probes (e.g AP29eco) data is printed at end of measurement sequence.
Printing of the current value can also be requested by an RS232 command or
ordered manually by pressing
PRINT . See “Connector pin configuration” on page 33.
* A custom APC program setting the MEAS flag prints as AP55/AP29eco and an APC
program not using MEAS flag prints as P50.
Detection data output
The Detection Data Output option is intended for automated scanning of weld seams
etc.
Note: The Detection Data is expressed in arbitrary units. Detection Mode signal is not
affected by calibration!
Table 8-9. Communication specifications.
The data format for Detection data output contains of ten ASCII characters. Nine
characters show the value in engineering format (See “Engineering format” on
page 19), and one character shows linefeed (LF).
The print time is 50 Hz continuous streaming data.
Note: Data rate is 25 Hz when Sensistor ISH2000 HySpeed is running in Service Display
Mode .
RS232 serial communication
The most commonly used Sensistor ISH2000 HySpeed functions can be started/
configured over the RS232 interface.
