This command writes N ( N =1...64) values Y
1
... Y
N
consecutively starting at the user
memory address R ( R =0...63). Note, that N + R must be <=64. This command must be used
economically , because the flash memory is designed for typ. max. 20000 flash cycles.
Each time this command is executed, it will trigger a flash cycle.
Example Communication:
Command:
#WRUM ˽ 0 ˽ 2 ˽ -16 ˽ 777
↵
Response:
#WRUM ˽ 0 ˽ 2 ˽ -16 ˽ 777
↵
This example shows a command which writes the value -16 into the memory address 0,
and the value 777 into the memory address 1.
5.4.14 #ERRO – Response if Error Occurred
If an error occurred, the device will give the following response:
Command: any command
Response:
#ERRO ˽ C ↵
This error response is mostly given, if the master did not send the command with the
correct communication syntax. The output parameter C represents the general
PyroScience error types as given by the following table.
Note: Warnings and errors directly related to the sensor measurements (e.g. a broken
Pt100 temperature sensor, or a "worn out" optical pH sensor) will not result in such an
#ERRO response. Instead, such warning and errors are given in the output parameter
R
0
of the MEA command (see above).
C Error Type Description
-1 General A non-specific error occurred.
-2 Channel The requested optical channel does not exist.
-11 Memory Access Memory access violation either caused by a not
existing requested register, or by an out of range
address of the requested value.
-12 Memory Lock The requested memory is locked (system register) and
a write access was requested.
-13 Memory Flash An error occurred while saving the registers
permanently. The SVS request should be repeated to
ensure a correct permanent memory.
-14 Memory Erase An error occurred while erasing the permanent
memory region for the registers. The SVS request
should be repeated.
-15 Memory
Inconsistent The registers in RAM are inconsistent with the
permanently stored registers after processing SVS. The
SVS request should be repeated.
