Siemens SIPROTEC 5 User Manual

Adding a USART Module
Add a USART-AB-1EL or a USART-AC-2EL USART module in DIGSI to the device. The USART module must be
inserted at one of the plug-in positions for communication modules in the base module or in the CB202
expansion module (refer to the following figure).

Selecting the SUP Protocol
Select the Slave Unit Protocol (SUP). This protocol is responsible for the communication between the SIPROTEC
5 device and the 20-mA unit.

Communication Settings
Make the communications settings for the relevant serial channels. For this, use the default settings specified
by the 20-mA unit. Normally, you must adapt only the parameterization of the SIPROTEC 5 device to the
settings of the 20-mA unit. Make sure that the setting values in both devices are the same. The settings of the
Non-flickering light (on/off): is not relevant for the RS485 interface.

NOTE
The driver for the USART module for the SUP protocol is not preinstalled as standard for the initial use of
this interface (following the firmware update).
