As example..if you have the drive connected to the profibus network then you can set it up to send the values of voltage/current to your PLC and from there you can send them to the HMI in an I/O field. So..there are ways and if you say the exact setup that you have or wish to make then its possible to get more specific answers.

xuanphu Posts: 146 Rating: (0)	Thank you Catalinch ! I mean ..i just had 3 pumps for a discharge feed water pipes system...and they was being controlled by PLC ..so...when I'm operating them through HMI (Monitor LCD ) I want to display the Voltage and current value .... But I dont know how can to make it on I/O filed of WinCC flex... Thank you !

But I dont know how can to make it on I/O filed of WinCC flex... Thank you ! Hello xuanphu; You control the pumps by PLC... does the PLC read the current and voltage values for the pumps? Are there current and voltage sensors on the motors that send these readings to the PLC? If so, what registers (data address) are dedicated to these current and voltage values inside the PLC? If you can answer this question, all you have to do is to create tags in the WinCC Flex program that connect to these PLC addresses and connect them to an IO Field in your HMI pages. But first you must ensure that these values exist in the controlling PLC. Hope this helps, Daniel Chartier

Are they "Electric Drive operated" pump or "Simple DOL Feeder/Starter". . If it is drive operated then drive may provide Current & Voltage as Analog Input of PLC. . But if it is a simple DOL then Energy Meter with Modbus Capability or converter which provides Current & Voltage as Analog Inputs to PLC is required. .
