Posted 30 Jun 2015 Hi, I am looking for a Modbus TCP based AI and DO data acquisition module and scada program. The analog inputs are 4-20 mA . SCADA should be able to communicate over Modbus TCP( I think every SCADA does that but just want to make sure). Can you guys please suggest if you know something good fit my application? Thank you, Share this post Link to post Share on other sites
Posted 30 Jun 2015 Hi Omar, What is the DO type?(Sink, source or relay) How many tags will be used in the SCADA? ICP DAS USA has a free SCADA software which is called EZ Data Logger. You can check it out from the link: http://www.icpdas-usa.com/advanced_ez_data_logger.html?r=kaan But, the free version requires one ICP DAS DAS product is connected to the SCADA. Here is a PET-7017 8 channel AI and 4 channel DO. It communicates over Modbus TCP and supports PoE. http://www.icpdas-usa.com/pet_7017.html?r=kaan I hope, this helps.
