我们一个项目做失重计量,老外推荐用Hasler的SCM2-P控制器,这个东西很贵,但是我看了简介好象它就相当于一个PLC做PID控制啊,我们自己有PLC/DCS,是不是就不需要这个东西了啊?
下面是简介:
-the acquisition of analog signals from the feeder
-to handle the measured and calculated values as well as feeder status
-to cantrol and regulate the feeder motor
-to handle the feeder and programmable alarm parameters
