Witam! Posiadam DL-RS1A wraz z czujnikiem odległości serii GT2 firmy KEYENCE. Chciałbym sczytać wartość odległości używając do tego sterownika SIEMENS S7-1200. Problem pojawia się w trakcie konfigurowania bloku odpowiedzialnego za komunikację z modułem DL-RS1A. Próbowałem go konfigurować już na wiele sposobów, jednak mimo tego nadal nie mogę odczytać wartości. Instrukcja do tego czujnika i modułu jest w załączniku. Na dodatek otrzymuję błąd nr 8180 czyli "Invalid value for the port ID". Chciałbym prosić o pomoc w rozwiązaniu tego problemu. http://obrazki.elektroda.pl/3338744300_1339937249.jpg

GT2-70 Series Instruction Manual
● Effects of surrounding air temperature
To use the GT2-70 Series with high accuracy, do not use the GT2-70
Series in an environment in which the surrounding air temperature
changes sharply.
It will take about 40 minutes for the 12 mm type, and 60 minutes for
the 32 mm/50 mm type for the internal temperature to stabilize
when the surrounding air temperature has changed by 10°C.
● Warming up
The circuit is not stable immediately after the power turns ON, which
sometimes causes the indicated value to gradually fluctuate. Wait
about 5 minutes when using the GT2-H12K(L)/A12K(L) and about
10 minutes when using the GT2-H32(L)/H50/A32/A50 after the
power turns on before starting operation.
● Handling of the sensor head
• The GT2-70 Series and peripheral devices are precision machines.
■ Symbols
Do not drop, or cause any other impact to these devices. Doing so
may cause damage or malfunction.
• Do not apply weight greater than what is listed below to the spindle.
Do not apply rotational torque. Otherwise the spindle may break.
• Although the sensor head (GT2-H12/H12K/H32/H50/A12/A12K/A32/
A50) has a waterproof structure, avoid using in water or places where
liquid such as water and oil may come into contact with the sensor head.
The following symbols alert you to matters concerning the
prevention of human injury and product damage. Be sure to read
these messages carefully.
WARNING

Tips for Convenient Functions
■ Automatic setup of limit values
■ Limit output function
This function automatically sets an upper limit value (HIGH setting
value) and a lower limit value (LOW setting value).
For master workpieces, set by " tolerance tuning " ; and for actual
works (good or defective), set by " two-point tuning " .
This function can detect and output the mechanical movement of
the spindle on the contraction and extension sides. The stroke end
of both sides can be detected, so this function can be used for
interlocking the device.
● Tolerance tuning
This is a method for setting a range based on
the detection value of a master workpiece
when the master workpiece is available.
Note
The limit output function cannot be used on GT2-71MCN/
71MCP (analog output type).
