CiMeterX.TechMeter

[Didierp]

Hi everyone, I'm a new user of Citect Scada software, even though I have some experience using another kind of HMI software, this one has been a challenge for me. Actually, I'm working with an UPS which uses a Modbus TCP/IP protocol and I can see a good communication between my Scada and the UPS, nonetheless I have an issue, probably a silly one, that I'm trying to sort out with not success. Any way, I want to use a CiMeterX.TechMeter. On its properties I chose VALUE and as an associate tag I have a Variable Tag (ULONG) called Voltage which is linked with a register (32-bit Fixed Point Scaling Format), somehow it is not working. When run my project this ActiveX is showing me 0 as a value instead 235 as I expect. I have used this Variable tag (Voltage) linked with a Number and it worked, I mean, using that Variable which has a register associated and then linking this Variable with a Number, it is possible to watch it working ( Register--->Variable Tag--->Number), but if I use the same Variable linked to the ActiveX it doesn't work (Register-->Variable Tag-->ActiveX) In order to see whether my ActiveX is ok, I create a ULONG Local Variable (called Test) then I create a Cicode Object (Test=20), the ActiveX worked, (Local Tag-->Cicode Object-->ActiveX). I can't understand why it is not working simply linking a Variable tag with the ActiveX (Register-->Variable Tag-->ActiveX). Variable Tag Name: Voltage Raw Zero Scale=0 Raw Full Scale=65535 Eng. Zero Scale=0 Eng. Full Scale=100 Data Type ULONG, LONG, REAL CiMeterX.TechMeter: Min Value=0 Max Value 100 Tag Association: VALUE Voltage Thanks in advance to anyone who wants to help me.

Have not used it for a while but if I remember correctly you have to scale the meter to the full value.

Hi BobB, Do you mean from 0 to 65536? Thanks, Didier
