UFS8000 RS485 80
17. RS485
Attention ! This chapter only applies to control unit type UFS8x1x-xxxx.
The controller has an RS485 connection.
The RS485 connection can be used for data
logging (status / measurement), alarms and
process data. This chapter will explain how
this can be set.
The RS485 menu is located in the main
menu.
17.1. Configuration
17.1.1. Configuration in the controller
The configuration of the RS485 connection is programmed.
The default connection is configured as follows:
- Baudrate 9600 Baud
- Data bits 8
- Parity No
- Stop bits 1
Also you can set the protocol that should be activated on the serial line. There is a choice between the
log functions and the Modbus compatible function.
17.1.2. Configuration of the “Hyperterminal”
The controller can be connected with a PC by means of an RS232 / RS485 converter, which is not
included in the delivery. For example, a “Hyperterminal” can be used to consult and possibly store the
data sent by the controller. “Hyperterminal” is routinely available in
“Windows” under “Desktop accessories – Communications”.
17.2. Log functions
There are three types of log functions: alarm logging, data
logging (status / measurements) and process information
logging. Below is an explanation of how these can be set.
