摘要:
Field devices are commonly used in unprotected environments, which means that these field devices and the conductor pairs connecting the field devices to the input modules/output modules of an automation installation are exposed to significant climatic and environmental factors. These factors have a detrimental effect on the transmission quality of the signals to be transferred between field devices and modules, which may result in erroneous measurements and dangerous operating states during control of a technical process. Measures to simplify monitoring of the transmission medium are proposed.
摘要:
In an automation system, a control device processes measured values received from automation components and generates control values for the, or for individual, automation components and/or other automation components. In order to shorten down times when replacing an existing control device, the new control device is tested during operation of the existing control device, for which purpose the measured values and control values are wirelessly transmitted to the new control device and the control values generated by the device are compared to the control values generated by the existing control device. After the test, the control values generated by the new control device are output to the automation components instead of the control values generated by the existing control device.
