Page 10: Functions For Hot-Runner
Operation Functions for hot-runner To operate with the protocol extension for hot-runners only a few additional inputs and outputs are needed. w The operation of the automatic controller can be switched over from remote to local operation. Therefore the inputs di1 to di3 or the F-key are available. In local operation a start-/stop functionality can be achieved by switching on and off the controller (for switching off put the set-point SP to OFF;... -

Page 14: Communication Protocol
Communication protocol 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. -
Page 15: Data Format
Communication protocol Data format For transmission of block length and checksum, the hexadecimal format is used, whilst set-points and process values are transmitted in BCD format. For transmission, hexadecimal values are converted into ASCII. For simplification, values above 9 (A-F) are coded as 3Ah - 3Fh instead of 41h-46h (ASCII A-F). Protocol structure Address Length... -
