6FC5203-0AF02-0AA2 Siemens OP012 Membrane Keyboard

Direct control key module of Siemens 6FC5203-0AF02-0AA2 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 6FC5 203-0AF02-0AA2 Terminal Keypad 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 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 operator panel front of Siemens 6FC52030AF020AA2 Membrane Keyboard Keypad. The PROFIBUS is completely isolated from the DKM/operator panel front by means of an opto-coupler and DC/DC converter.
The DKM of 6FC5203-0AF02-0AA2 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 are handled as if they were 16 ordinary digital inputs.
