TAC Xenta 511 conversion to StruxureWare

Issue

In the Xenta Servers, it is possible to set the communication port to RS232 or RS485.
In StruxureWare this is not possible on the AS.

Environment

StruxureWare
Xenta Servers

Cause

The AS serial ports are RS-485, not RS-232.

Resolution

There are two solutions to consider when Xenta is using an RS-232 connection:

  • If the connected device also has a RS-485 connection switch to that. (Optionally replace the device with one that has RS-485.)
  • Use a RS-232/RS-485 converter. The converter must have automatic data direction detection and control on the RS-485 side, since our Automation Server devices have no RTS signal (to enable the transmitter) available externally.
