Precautions TKY(211) will not operate correctly if I/O refreshing is not performed Input Unit
connected to the ten-key keypad after TKY(211) is executed. Consequently,
set the input time constant for the Input Units used for the data line input word
to a value that is shorter than the cycle time, or do not connect the ten-key
keypad to the following Units.
• Basic I/O Units or High-density I/O Units mounted in a SYSMAC BUS
Remote I/O Slave Rack
• Communications Slaves (DeviceNet or CompoBus/S Slaves)
Example In this example, TKY(211) reads key inputs from a ten-key keypad and stores
the inputs in CIO 200 and CIO 201. The ten-key keypad is connected to
CIO 0100 (allocated to a CS1W-ID211 16-point DC Input Unit).
3-23-7 HEXADECIMAL KEY INPUT – HKY(212)
Purpose Reads numeric data from a hexadecimal keypad connected to an Input Unit
and Output Unit and stores up to 8 digits of hexadecimal data in the specified
words.
This instruction is supported only by CS/CJ-series CPU Unit Ver. 2.0 or later.
