both red and green
LED flashes
0.1 sec on,
0.1 sec off
count-flashes
start when switch
is pressed:
0.5 sec on,
0.5 sec off
time-out:
60 sec
Press switch and count red and
green flashes for baud rate
setting.
Release after desired count.
Counts to max. 3 and then starts
at 0 again.
When counting failed, keep switch
pressed and restart counting for
next attempt.
Note: selection of 0 means: No
change
Instrument returns to normal running/operation mode.
Changes are valid when they are made within the time-out times.
Actual setting can be checked by pressing the switch 3x briefly with intervals of max. 1 sec. for readout
the bus-address/MAC-ID and baud rate.
Value zero will be indicated by a period of 1 sec. off (0.5 sec. off + 0.5 sec off).
When value zero is wanted, press switch shortly and release it again within 1 sec.
Before each action of flash-counting, the LED(s) to be used for counting will flash in a high
frequency. (Pattern: 0.1 sec on, 0.1 sec off). As soon as the switch is pressed down, this LED
(or both LEDs) will be off, and the counting sequence will start.
The parity setting cannot be read or changed using the micro-switch
3.5.2 Implementation class
The physical and data link layer is implemented conforming to the "basic slave" implementation class as
described in the document, “MODBUS® over Serial Line specification and implementation guide V1.02”.
