6.18.3.5 Deactivate probe-breakage recognition
In case the temperature measurement is checked by a controlled calibrator, an interaction might evolve
between the high impedance calibrator output and the device input. Than the signal comes in noisy and
not usable for calibration. The following procedure can be used to deactivate the probe-breakage
recognition:
Message 1:
The CAN-ID is the master-ID of the configured module (default: 2032). 8 bytes, Intel-format.
Contents
0xC0
0x00
Slave-ID (Standard 2033)
0x00000000
Bit
0-7
8-15
16-31
32-63
Message 2:
The CAN-ID is the master-ID of the configured module (default: 2032). 8 bytes, Intel-format.
Contents
0xC5
0x00
Serial number
On-/Off-command
0x00
Bit
0-7
8-15
16-47
48-55
56-63
Serial number of the module as 32 Bit number
Command to activate the probe-breakage recognition: 0x11
Command to deactivate the probe-breakage recognition: 0x10
After the module has executed the second message, the module sends an answer message using the
slave-ID.
Example to switch of the probe-breakage recognition:
Slave-ID for this example is 2033
Serial number of the example module is 871682
The message on the bus would look like:
message 1: c0 00 f1 07 00 00 00 00
message 2: c5 00 02 4d 0d 00 10 00
answer e6 xx xx xx xx xx xx xx
Message 1 is sent first and then Message 2 (delay > 1 ms).
The effect of that change takes up to several 100 ms.
