3.6 Connection interfaces (option)
The serial port can run the following functions:
-Call data
-Program and call parameters
Port parameters are:
-the transfer speed (baud rate),
-the parity bit,
-Number of stop bits,
-the address with which the controller is addressed by a master.
These port parameters can be set on the programming level (lines
51, 52, 53 and 54).
The following standard interfaces can be connected to the counter:
-RS232, RS422, RS485
Interface characteristics
RS232
Full-duplex transmission with the following features:
-asymmetric
-3 lines
-point-to-point connection - 1 emitter and 1 receiver
-distance of data transfer: max. 30 m
RS422
Full-duplex transmission with the following features:
-symmetric
-4 lines
-point-to-point connection - emitter and receiver (max. 32 units)
-distance of data transfer: max. 1500 m
RS485
Half-duplex transmission with the following features:
-symmetric
-2 lines
-multi-point connection - emitter and receiver (max. 32 units)
-distance of data transfer: max. 1500 m
3.7 Executing the test routine
The test routine is described below.
To start test
Press the
and
keys simultaneously.
Switch on (hold down the above keys at the same time).
●
All the display segments will be displayed automatically in se-
quence and are thereby tested for functional capability.
Test extension
Using the
key, test the keyboard, the inputs, outputs and
interface in sequence.
No machine functions may be connected when the outputs are
tested.
