Operands:
S: Start device for key input (occupies 10 consecutive devices) D
1
: Device for storing keyed-in
value D
2
: Output signal (occupies 11 consecutive devices)
Explanations:
157. This instruction designates 10 external input points (corresponding to decimal numbers 0 ~ 9)
starting from S, connecting to 10 keys respectively. Input point started from S triggers
associated device in D
2
and D
2
maps to a decimal value, a 4-digit decimal value 0~9,999
(16-bit instruction) or an 8-digit value 0~99,999,999 (32-bit instruction). The decimal value is
stored in D
1.
158. There is no limitation on the times of using this instruction in the program, however only one
instruction is allowed to be executed at the same time.
Program Example:
159. Connect the 10 input points starting from X30 to the 10 keys (0 ~ 9). When X20 = ON, the
instruction will be executed and the key-in values will be stored in D0 in BIN form. The key
status will be stored in M10 ~ M19.
