  • Connect the USB to RS422/RS485 adapter to the USB port of the GSR.

3. Configuration in SmartControl

Once we have the elements installed, we continue the process in the SmartControl platform.

1.First of all you must make sure that the reference (name) of the SJEC element follows one of the following options:

  • TAG-NAME (example: ESCALERA IZQ-A)
  • TAG (example: A)

In this way, each ladder has its own TAG, so if you want to have more than one ladder per GSR, the following ladders must have a unique TAG.



2. The customer must then individually link each relay element and follow the installation process. At the end each of the relays must have a name, which, unlike the ladder, is specific to the functionality of each relay, it must follow the NAME-TAG rule:

  • Start-TAG for the start relay.
  • Stop-TAG for the stop relay.
  • Reset-TAG for the reset relay.
