1) Front connection for local communication

The relay is connected to a PC used for local parameterization via the infrared port

on the front panel. The front connection allows the use of the SPA bus protocol only.

The optical front connection galvanically isolates the PC from the relay. The front

connection can be used in two different ways: wirelessly using a PC compatible to

the IrDA®‚ Standard specifications or using a specific front communication cable

(refer to Section 6. Ordering information). The cable is connected to the serial RS232 port of the PC. The optical stage of the cable is powered by RS-232 control

signals. The cable has a fixed baud rate of 9.6 kbps.

The following serial communication parameters are to be set for RS-232:

* Number of data bits: 7

* Number of stop bits: 1

* Parity: even

* Baud rate: 9.6 kbps

Relay data such as events, setting values and all input data and memorized values

can be read via the front communication port.

When setting values are altered via the front communication port, the relay checks

that the entered parameter values are within the permitted setting range. If an entered

value is too high or too low, the setting value remains unchanged.
