Direct control key module of Siemens 6AU1350-2AH23-1BE1 Touch Screen Display Terminal Keypad
The task of the direct control key module (DKM)is to directly transfer the operating signals for the two rows of keys on the sides of 6AU1 350-2AH23-1BE1 operator panel front to SIMATIC without diversion through intermediate firmware. The signal-to-key assignments are shown in the table and figure in section: "Interfaces"-"Operator panel front."
The DKM can be combined with operator panel fronts of type OP 012, OP 012T, OP 015A or TP 015A.
The DKM of 6AU13502AH231BE1 HMI Panel Glass Terminal Keypad converts the key signals to the PROFIBUS DP protocol by means of the ASIC LSPM2(PROFIBUS DIN 19245 Part 1,12 MBaud).
Power is supplied via the 6AU1350-2AH23-1BE1 operator panel front. The PROFIBUS is completely isolated from the DKM/operator panel front by means of an opto-coupler and DC/DC converter. The DKM operates as a slave on PROFIBUS. The address can be set between 1 and 99 using rotary switches. Two bytes of data are transferred.
In SIMATIC, the keys of Siemens 6AU1 350-2AH23-1BE1 Touch Digitizer Membrane Keyboard are handled as if they were 16 ordinary digital inputs.
