Citect v7.40 SP1 - PM710 meter - FloatMode problem

[agoslinski]

Hello

Recently I got Schneider Electric's meter PM710 which I connected to citect server through Modbus to TCP gateway Moxa MB3170.
With program such as CAS Modbus Scanner I have no problem reading registers. For example:

401000 = 0x44C3 401001= 0x03F1

Float value of 0x44C303F1 is 1560.1232 (exact value visible on meter).
If I understand correctly I should choose FloatMode = 1 (3210) but unfortunately its not working.
I used all FloatMode options (0-3) and none of them give me sensible values.

My configuration:
[PM710]
Firmware 3.110
MODBUS RTU
Address: 19
Baud rate: 9600
Parity: None
Connection: RS-485 (2xwire)

-citect.ini-

FloatMode = 3
-Equipment-

I/O Device {equipment.IODEVICE}
Address: 41000 (I also tried 401000 and 301000)
Cluser Name: {equipment.CLUSTER}


Could You please help me with my problem?

Best Regards

I cant remember the float mode that we use for the PM710 and from memory Modnet 3 is 0 based so for register 41000 you will need to have it as 41001 in Citect i think ?

I get Address on bad boundary when I use MODNET 3 and 41001 address.
Even when I ignore this warning I still can't get sensible date using any of FloatMode options (0-3)

Change the ini setting [GENERAL] CheckAddressBoundary = 0

I know what CheckAddressBoundary does. It does not help with my problem.

Well it will help with not getting an address on bad boundary error....

No idea what your issue is then, for what its worth we use MODNET2, don't make any changes to the FloatMode and they work, used this setting on 1000's of meters.

I am sure you know this too but if you have anything else in your ini defining FloatMode then that may be causing issues, for example:

[MODNET] FloatMode =1 overrules [MODNET.PORT.DEVICE] FloatMode =3

 

[agoslinski]

Thanks for replay but unfortunately MODNET 2, odd addresing and disabling FloatMode does not work. Every device in my network has separate [MODNET.PORT.DEVICE] section.

I fixed the problem using MODNET 3 address offset of -1 (401000 => 400999) and FloatMode = 1
