4.7. Interface commands
Reading (S...) and writing (L...) commands are available for setting the parameters and for operating and
controlling the PIREG-C2. The controller parameters can be set and sealing processes controlled with
these commands. The factory settings can be reset with a command (WESE).
At the RS232 and USB interfaces, each telegram of a command begins with the character "S" or "L",
depending on the type of command. The response telegrams to read commands begin with the character
"A", followed by the name of the command. The response times for read commands are between typically
0.5 ms and a maximum of 1 ms, if nothing else is indicated. The data in the response telegrams are sepa-
rated by blank spaces.
In addressed RS232 communication, each telegram starts with the address, which consists of three dig-
its, and is separated by a space from the telegram structure of a command, an acknowledgement or an
answer described above.
For the RS485 interface, the command for writing is identified with 69h and for reading with 89h in the
functional field FF. In the following examples, 21h is used for the controller's device address (GA). The
terminator of each telegram at the RS485 interface is 16h.
The limits of the input values are monitored.
4.7.1. AHUE command
Syntax Read: LAHUE
RS232/USB: Response: - Variant 1: AAHUE a uuu ooo ttt
- Variant 2: AAHUE a uuu ooo sss eee
Write: - Variant 1: SAHUE a uuu ooo ttt
- Variant 2: SAHUE a uuu ooo sss eee
Response: OK or error acknowledgement; response time max. 6 ms
Release: not in the On or calibration state
Syntax: Read: Control set, BI = 0Bh
RS485: Response: - Variant 1: Long set with DB0…DB4
- Variant 2: Long set with DB0…DB6
Write: - Variant 1: Long set with DB0…DB4, BI = 0Bh
- Variant 2: Long set with DB0…DB6, BI = 0Bh
Response: short set, OK or error acknowledgement; response time max. 6 ms
Release: not in the On or calibration state
Description: Setting and querying the settings of the heating monitoring. The heating monitoring is a
monitoring function with two variants. In variant 1, a maximum time is monitored in which
the heating must be carried out. In variant 2, a time range is monitored within which the
heating must take place.
With “a” the monitoring function is activated (a=1) and deactivated (a=0). A temperature
OK range around the nominal value is set with lower limit "uuu" (5…99K) and upper limit
"ooo" (5…99 K) in K. In variant 1, the actual value of the PIREG-C2 must have reached
the temperature OK range before the heating time "ttt" has expired in 0.1 s (0 ... 99.9s). In
variant 2, the actual value must have reached the temperature OK range within the time
window "sss" in 0.1 s (0...99.8s) until "eee" in 0.1 s (0.1...99.9s). Otherwise the PIREG-
C2 switches to the error state (error 8).
Monitoring of the heating time is restarted if the set value increases by more than 5°C.
