Smart Devices Diagnostics Device self-diagnostics can be divided into two classes: continuous and on-demand. Continuous self-diagnostics runs autonomously entirely onboard
When intelligent devices are not communicating or show abnormal status for any reason the DD file often get blamed first.
Process variables and manipulated variables are the most important pieces of information from the devices. NAMUR has identified that the status
Study about the history of 4-20 mA signals used in the industrial instrumentation. Other signals are 3-15 psi, and 10-50 mA
The IEC also defines how manufacturers should mark the values of resistors and capacitors in the standard called IEC 60062.
The sensors and actuators that are connected to the inputs and outputs (IO) of a Programmable Controller or PLC are
Calibration can be carried out using a handheld communicator in the field, a laptop on the bench in the workshop,
