Product:07KT93 GJR5251300R0101 ABB Basic Units

07KT93 is ABB Advant Controller system basic unit. The access to the AC31/CS31 basic units 07KT93 and to the communication processor 07 KP 62 of ABB Procontic T200 is conducted via the serial interface COM1. Every operating and test function of the PLC can be called via an ASCII clear text telegram. The operating mode "active mode" must be set on the serial interface.

Connectable units:

– Terminal in the VT100 mode

– Computer with VT100 emulation

– Computer with a program for the handling of the clear text telegrams of the operating and test functions

The processing of the PLC program has higher priority than the communication via the serial interfaces. The PLC operates the receiving direction of the serial interface COM1 with interrupt-control. During a running PLC program cycle incoming characters respectively trigger an interrupt impulse, which interrupts the running PLC program until the received characters are stored in the reception buffer. To avoid a permanent interruption of the program processing, the PLC controls the data reception via the RTS line so that it takes place in the breaks between two PLC cycles. The PLC processes the jobs received via COM1 exclusively in the breaks between the PLC program cycles. The output of characters via COM1 is also only conducted in the breaks between two program cycles. The lower the utilization rate of the PLC is, the longer the breaks are between the program cycles and the higher the possible communication rate is to COM1.
