Setting The Communication Parameter; Setting Parameter Seating Mode In End Position Closed, Parity Bits And Number Of Stop Bits; Setting The Modbus Address - AUMA AM 01.1 Operation Instructions Manual

Operation instructions
7.12 Setting the communication parameters

7.13 Setting parameter seating mode in end position CLOSED, parity bits and number of stop bits

7.14 Setting the Modbus address

Actuator controls AUMA MATIC AM/ AMExB/ AMExC
Push buttons:
T1 RESET
T2 MODIFY
T3 CHANGE MODE:
DEFAULT MODE: for status indication and basic programming,
ADDRESS MODE for address setting
BAUD RATE MODE for baud rate selection
Push button 3 (CHANGE MODE) is used to switch between the following
modes:
1) DEFAULT MODE is characterised by LED 7 (green) being switched off.
Display and modification of type of seating in end position CLOSED,
parity bits and stop bits as well as display of DataExchange, status,
BusActivity, and LocalError.
2) ADDRESS MODE is characterised by LED 7 (green) being illuminated.
The address is adjustable.
3) BAUD RATE MODE
is characterised by the blinking of LED 7 (green).The baud rate is adjustable.If no
push buttons are pressed for 30 seconds, the display will revert to DEFAULT MODE.
The push button MODIFY allows incrementation of the figure shown in the
LED row. The new value is immediately accepted in the DEFAULT MODE.
For ADDRESS MODE and BAUD RATE MODE, the value is only accepted
when leaving these modes.
When not pressing push button CHANGE MODE, you are in the DEFAULT
MODE (LED 7 is not illuminated). LED 0, LED 1, and LED 2 show the value
of the three mentioned parameters:
LED Parameter
0 seating mode in end position CLOSED
1 Parity setting
2 Number of stop bits
Push button S3 "MODIFY" is used to set these parameters. If, for example,
type of seating in end position CLOSED = torque seating, parity setting =
even parity, and number of stop bits = 1 stop bit is to be selected, the combi-
nation 001 must be illuminated for the first 3 LEDs. The push button
"MODIFY" is operated until this combination appears. The parameter values
become immediately valid.
The Modbus address is set using push buttons T2 and T3. This is done
according to the following sequence:
(a) Press push button T1 CHANGE MODE (hold down for 1 to 2 seconds):
The green LED 7 ADRESS MODE is illuminated (not blinking);
it indicates the programming mode for the Modbus address.
The actually set Modbus address is displayed as binary coding by LEDs
6 to 0 (1 to 127).
(b) Set desired bus address using push button T2 MODIFY:
(Factory setting: slave address 2)
(c) Each pressing of the push button increments the address value by one.
Address 1 will follow after address 127. If push button T2 MODIFY is
held down (approx. 1/3 s), the incrementation is done automatically.
