Dear Mr.
Ishikuma,
please be informed that
we were able to solve the outstanding communication problems by our software.
This software in the meantime has passed our internal tests
successfully.
In an earlier mail
(dated Sept. 17) you stated
Quote:
We have software that was specially
designed for the PTB. This special software can be used with our
standard configuration (HGC – HFA – HDM) and running with HGM on the
same PC.
As I mentioned before this software
was designed to work in accordance with the PTB requirements. When a manual
calibration is performed with this software, a limit check will be carried
out by this software.
Unquote.
We like to learn more
about this. So please provide this software and its documentation to allow
crosscheck against our solution.

<<Problem2
Integrity of SLD data.doc>>
Dear Dr. Grexa.
Here is the
final report of the problem #2, SLD Comm. Error detection.
Please refer the
attachment.
Conclusion
:
In the experiments in Yamatake, we
verified following.
When Fieldbus line is cutting
between SLD and HGC, SLD return Ethernet response with SLD return code(Result)
is not 00 00 00 00 value, and no HGC_data.
When HGC's power is off, SLD returns
the same response.
Recommendation :
Please check SLD return code(Result)
in every SLD Ethernet response.
And when SLD return code(Result) is
not 00 00 00 00 value, please interpret that communication between SLD and HGC
is NO GOOD.
Could you please convey all these
information to your software engineer?
And should you have
anything uncertain, please let us know.

Actual Status on Technical Problems
Dear Mr. Ishikuma,
please excuse the impolite wording
of my last email.
Anyway, we are now working on a
software solution which uses HGC features as they are – without software
modification on Yamatake’s side.
Hopefully within the next few days
we definitely will know, whether this will work. We’ll keep you
informed.

Betreff: RE: Actual Status on

Dear Dr. Grexa,
I was not familiar with the detail
mechanism of calibration RF check function in PTB approved
system.
That's why I said "automatic
calibration is used in Yamatake PTB system" in the last
meeting.
Please forgive
me.
We discussed "RF check function was
necessary" for the first time on September 9.
I didn't know this point was an
issue, since it was not written in you e-mail on August 19 nor
earlier.
Anyway, could we ask you to have
this RF check in your system? Then is it still better to use HGC's semi-auto
calibration?
Any feedback of your choice/design
would be appreciated, which would help us in better understanding if we need to
confirm further details. I would like to have more frequent communication with
you in closing those issues (if you don't mind).
Thanks for your cooperation and best
regards,

Dear Mr. Mayeux,
thank you for your message.
With respect to Problem
#2:
We follow your advice to recheck our
software. At first glance our software engineer stated, that the error codes as
described can be seen during establishing the connection, but not when failures
occur while the connection is already active. But he will investigate in detail
soon.
With respect to Problem
#3:
Existence of a special “PTB
software”, controlling the calibration and running in parallel to HGM on PC, is
a new information – more than surprising to come up at this stage of our
cooperation. We lost a lot of time and money, because we did not know about it
earlier and therefore went down a dead end road.

Betreff: RE: Actual Status on
Technical Problems
Dear Dr. Grexa
During our meeting of the 9th
September in Butzbach we talked about the issues for the calibration
mechanism.
Problem#2
There's no signal or sign in case of
FB communication loss or power loss.
Our engineers checked the actual SLD
error report at communication failure.
They see random data in the examples
from RMG, and they have some worries.
Could RMG check the software
again?
(1) status value
The last column in the excel file is
'status' and this is the SLD error report.
That value is different than what we
would expect according to our SLD engineer.
So there might be a probability that
the RMG software is misunderstanding the status?
It’s
ethernet message format.
typedef struct {
unsigned char
ServiceCode;
unsigned char
SubCode;
unsigned short
LinkAddress;
unsigned long
InvokeId;
unsigned long
Result;
unsigned short
DataSize;
unsigned short
Dummy2;
unsigned char
Data[MAX_NET_DATA_LEN]; } LD_ETHERNET_MSG;
Result is 'status'(SLD error report)
This format is...
byte1 (MSB), byte2, byte3, byte4
(LSB)
byte1 (MSB) and byte2 = 0xC006
(fixed, means SLD result)
byte 3 = service
code
#define
SV_GET_SEGMENTS
0x01 //get segment
#define
SV_GET_NODES
0x02 //get node
#define
SV_READ_TAG
0x10 //read tag(read data)
#define
SV_WRITE_TAG
0x11 //write tag(write data)
byte 4 = error
code
#define
ER_ACCESS
0x01 //access error
#define
ER_SERVICE
0x02 //service error
#define
ER_INVOKE_ID
0x03 //invokedid error
#define
ER_TIMEOUT
0x04 //timeout error
#define
ER_RESOURCE
0x05 //resource error
#define
ER_VCR
0x06 //vcr error
#define
ER_OTHER
0x07 //other error
#define
ER_TAG_NOT_FOUND
0x08 //tag not found
#define
ER_DISCONNECT
0x09 //disconnected
#define
ER_DATA_SIZE
0x0a //data size error
#define
ER_INDEX
0x0b //index error
#define
ER_SUBINDEX
0x0c //sub index error
#define
ER_GROUP_NOT_FOUND
0x0d //group not found
#define
ER_GROUP_FULL
0x0e //group full
#define
ER_DEVICE_DEAD
0x0f //device dead
example
0xC0 06 10 09 (C0 06=error report
from SLD, 10=read, 09=disconnected) means that the SLD is trying to read data
from the HGC, but the HGC is disconnected.
(2) when check
'status'
Result ('status') is reported in
every ethernet response message.
RMG one line data included 14 HGC
data (scv, density, relative density, methane...).
It requires 14 times ethernet
communication, RMG software may check Result of every response, but the status
indication is only once.
How about another
indication?
Problem #3
During our meeting of the 9th
September in Butzbach we talked about the issues for the calibration
mechanism.
RMG requested a semi-automatic
calibration with the possibility to choose RF Limit check ON / RF limit check
OFF
Because the manual calibration has
not the RF Limit check option.
We consulted our engineers in
We have software that was specially
designed for the PTB. This special software can be used with our standard
configuration (HGC – HFA – HDM) and running with HGM on the same
PC.
As I mentioned before this software
was designed to work in accordance with the PTB requirements. When a manual
calibration is performed with this software, a limit check will be carried
out by this software.
By the way, HGC performs "manual
calibration" in the PTB approved system. Together with this special software,
systematic calibration is done automatically. Sorry we were wrong. It was not
HGC's own automatic calibration. "3.2 Calibration sequence example"
description in the attached documents shows this special software's calibration
sequence.
Can we ask to RMG to develop such a
software to work with their flow computer? The problem is that if we have to
develop such a software (semi-automatic with Limit check ON or OFF) it will not
be finished by the end of this year! Our engineers have projects until at least
the end of October.

Dear Dr. Grexa,
Concerning the problem #2, could you
please confirm the question that I sent you August 19 below?
In order to make sure "what is
happening at the time of SLD-Fieldbus line cutting", Yamatake engineer
would like to see the "random data" which was reported in your e-mail dated
August 19. Could I ask you to send it to us?

Dear Dr. Grexa,
Thank you very much for the update
!!!
I am pleased to hear good progress
has been made in your team !!
Referring to #2, I sent an e-mail
(the attached) to you on July 15.
Did you worked with the "SLD's
communication result message with service codes and error codes"which I sent
July 11?
Just a confirmation would be
appreciated.
Referring to #3, my understanding is
that RMG Flow Computer needs to pick up the timing of calibration start and
finish in automatic calibration.
Gas line switching mechanism is as
follows ;
- Auto calibration setting is
configured and downloaded to HGC by HGM through HFA
- RMG FC switches the solenoid valve
when the calibration time comes. (RMG FC needs to pick up that timing from
HGC)
- When calibration is finished, RMG
FC switches the solenoid valve back to the sample gas. (RMG FC needs to pick up
that timing from HGC)
Subject is Auto calibration, not
semi or manual calibration. Am I correct?
Your confirmation by return for this
point would be appreciated, too.
Very best
regards,

Subject: Actual Status on
Technical Problems
Dear Mr.
Ishikuma,
Mr. Koerte asked me to update you
with the actual status of HGC/SLD/Flow Computer communication problems. During
our meeting held in Butzbach on June 04th, we discussed 3 technical issues,
which had been addressed as
1.
stability of the fieldbus communication in case of HFA and SLD coexistence
2. “Integrity of the
data”
of the SLD unit even under bus line cutting situation
3.
control of the HGC 303 unit /manual or semiautomatic start of calibration
Referring to # 1:
Using the recent version of HGM 4.84
we find the communication on the field bus
“in healthy
condition”
error free (in presence of HFA and SLD at the bus). So this issue is settled now
by your new software.
Referring to # 2:
In case of line cutting off the
field bus or an undected power down of HGC unit, the SLD is
providing “random”
data on the modbus side. As this issue was not addressed by you any more we have
implemented in our flow computer some read/write check to test the healthy
condition of the whole communication line between
HGC via SLD to our flow computer. So
this had to be settled by an additional feature of our
software.
Referring to # 3:
As the semiautomatic mode of HGC,
which was intended to be used, turned out to be non compliant to our needs for
validation of the calibration results, we are still working on a software
solution on our side to avoid erroneous calibrations and to fulfil
PTB’s
requirements.
Please feel free to contact me, if
more detailed information is required.
