Communication protocol
KS50-1
TCont
supports a simple protocol for injection moulders and extruders
widely used in the plastics industry, which is used for connecting peripheral
equipment and easy simple data exchange. This protocol, which is also called
”ARBURG” protocol, is designed according to the specification of the Arburg
company.
g
This protocol is also supported by other machine manufacturers, e.g. Engel,
Krauss-Maffei, etc. Any adaptation required can be done by changing the
Baudrate or the parity.
Communication is according to the master / slave principle. KS 50-1 is always
slave and polled for a message by the machine control system. Exchanging
messages is done in half-duplex operation.
The transmission parameters are adjustable via the front panel or via
BlueControl

Exchanging messages is subjected defined time conditions:
w
Character delay time
T1:< 50 ms
(The max. possible time which can pass between sending of the start bits of
two successive bytes a message)
w
Acknowledgement delay time
T2: <100ms
(The max. possible time which can pass between the end of an inquiry sent by
the master and reception of the first character of the slave reply)
