Dear Colleagues, I need to upgrade the firmware of a Siemens Fieldbus positioner (SIPART PS2 FF). I want to know what hardware and software I need to do that. Any hint or guide is welcomed.

I am looking for remote Honeywell's Experion PKS training. Any hint? Moreover, is there any minimum system hardware available for Experion PKS by which I can learn by experiment without manipulating a real control system of the plant?

HI, This question may seems naive but sometimes we have to look back to detect vulnerable points in the control system for virus threats! Consider a control system which is connected to various package PLCs with individual Modbus links all using RS-485 physical layer and just transferring...

Hi, For Fieldbus instruments which have multiple measurements possible (e.g. mass flowmeters which can also give density) we can easily have all these measurements when designing HMI in Yokogawa's CS3000 environment. Is it possible to access these multiple measurements in CS3000 when the...

We are facing with some serious problem using our newly purchased Fieldbus Siemens positioners SIPART PS2 FF (N1-A413-7519177; **SIPART PS2 FF**, revision name:2.0 ; DEV_REV: 0X02; DD_REV: 0X01) in our control system which is Yokogawa's CS3000 R.3.08.50. We assign the positioners to the...

In intrinsically safe concept, we know that there is a limit for energy released in the hazardous location in case of a short circuit between transmitter's wires, for the worst case this limit is 20uJ. Nothing is said about the transmitter's power. Think that we have a 1 watt transmitter...

Just as one of my experiences with Yokogawa’s ProSafe-RS(R 2.02.00) system which may be useful for other control engineers to know. Online configurability means, you can change logics and take them into effect by downloading the modified logics into the controller (while the controller is...

I have developed a brand new method for flow measurement which eliminates most of the problems of traditional orifice plate method, I wonder how I can find a trustable company to invest. Does anybody knows what I can do?

There has always been arguments about whether it is better to use 110V instruments or PLC power supplies or 230V ones. In my country, main grid voltage is 230V. I would like to know if is it better to use PLCs or instruments which works with 230V in our industry or should I go toward 110V ones...

Hi, I am looking for a simple (and possibly free!) software like LabView PDA for panel PCs having Windows CE as their OS, any suggestion?

Hi, When we need a level switch signal, it is often recommended to use a level transmitter and produce the switch by software instead of using a level switch, why? This is also true for other transmitters. Any reason?

Hi, We have an E&H NXA820 tank scanner capable of communication with Modbus radars. We would like to use it for V1 network radars, is it possible to do some small modification on our NXA820 enabling it to communicate with V1 radars? I could not find any spare parts in E&H site. I don't want...

Hi folks, From time to time, I face with problem when dealing with a DP transmitter set up to measure the differential pressure of two distant points. Recently, we have installed a DP transmitter to measure the differential pressure of two points on a long tower. The distance between tapping...
