Expert’s answer: Output Promag P 300
The seamless integration is a relevant point to discuss! If you don’t have a clear connection between the field device and your control system you can lose a lot of benefits provided by diagnostic and remote configuration. However, if you don’t have a digital input, you need to know the different ways you can read the field information. People have the option to read field information via 4-20mA, pulse, or frequency. Then again, it really just depends on your requirements.
Old School Analog
With the new flow meter from Endress+Hauser you have a bunch of different ways to integrate all your information into the control system without too much effort. First, let’s talk about the analog method to connect the transmitter to the control system. The Promag P 300 has different ways to do that. You can use the 4-20mA active and passive option, Pulse, frequency, switch output, or relay.
Those are the “analog” ways to integrate the flow meter to the control system. Which one you use depends on your company and input options on the control system. Do a little research and choose the best one for your situation.
New School Digital
If you have digital communication with your field devices, you also have a bunch of options available. A few include HART communication, Foundation Fieldbus, PROFIBUS PA, and Modbus RS485. For sure, there is no lack of choices here. As a result, you can choose the best one to fit your application. In the meantime, if you are reading this article close to its launch, there are many options still not available. For example, EtherNet/IP, PROFINET, and 4-20mA+WirelessHART.
As soon as these protocol options are launched, the PROMAG P 300 will cover the majority of the communications on the field. Thusly, giving you the easiest way to integrate the flow meter to your control system. As a matter of fact, you can scale out the flow meter using the online applicator tools from Endress+Hauser or create the order code going to the device’s page on their website.
