Tagging Variables that have Data-type 'Double' in Citect

[rajsiyer]

In my present project, I have to interface an energy meter that has its kWh count in 64 bit Double format. Now that Vijeo citect hasn't a facility to create tags of the "double' type I am looking for a work-around to this problem. Thanks for any help/advise in this matter

If it's a MODBUS format look at it with a Modbus master simulator. A lot of the time, depending on the PLC maker, it can be seen as a long, double, or just an Integer. Again some tinkering should help. A lot of the time I have a double that is seen as a Float in the HMI. Hope this helps some...

Ni Hao a062549 Thanks a million. What I now understand is that Schneider has a small application created in C/VB that runs in the ibackground. However, in my case I was able to solve the problem by changing the firmware of the meter so that another address retained the value as 32 bit real. Thanks and all the best
