Control interface unit

Technical data Function

General specifications

The control interface unit is connected viathe serial interface to a higher-order controlsystem. The control interface unit receives thecommands for reading the code carriers viathis interface.Up to 4 read heads can be connected to thecontrol interface unit. The read heads can bequeried either individually or through cyclic switching. When a code carrier is detected, arelay contact remains closed for a specifiedamount of time. Using the Dip switches, it is possible toselect between various operating modes onthe control interface unit: fixcode, protocol3964R with interpreter RK512, protocol3964R without interpreter RK512 and 4-bitidentification system. With the "fixcode" operating mode, serialcommunication takes place via ASCIIcharacters. All commands consist of multiple ASCII characters. The control interface unit supports thecomputer coupling procedure 3964R, whichwas developed for programmable logiccontrollers; the commands are inserted intothe telegram frame of the procedure. In addition, the RK512 interpreter can be usedin combination with fetch telegrams.The "4-bit-ID-system" operating mode is designed especially for simple control tasks. In this operating mode, activation via theserial interface is not necessary. The controlinterface unit cyclically activates allconnected read heads.The first 4 bits of a data carrier programmedfor this operating mode are projected ontothe relay outputs for an adjustable period oftime. In this way, up to 16 different states canbe coded. With the relay outputs, pneumatic valves orcomparable control devices can be directlyconnected. Thus, the path via a higher-order control system is made superfluous. Number of read heads max. 4
