Answer

  • A DeviceHub device tag refers to the PLC tag/register. PLC registers hold PLC runtime information.
  • Tags are the actual input and output registers in a device to which sensors are connected. Every PLC has a tag and tags differ from PLC to PLC.
  • Examples of tags include: digital input, digital output, analog input, analog output, timers, counters, etc.
