AH500 Programming Manual 6.18.2 Explanation of Peripheral Instructions Symbol: S ： Initial device Bit D 1 ： Device in which the value is stored Word/Double word D 2 ： Output signal Bit 1. The ten external inputs starting from the input specified by S represents 0~9 in the decimal system. They are connected to ten keys. Users can enter a four-digit decimal value or an eight-digit decimal value by pressing the keys in order. The decimal value is stored in D 1 , and the output signals are stored in D 2 . 2. The operand S occupies ten bits. 3. The operand D 2 occupies eleven bits. Please do not change the states of the bits during the execution of the instruction. 4.
When the conditional contact is not enabled, the eleven bits starting from the bit specified by D 2 is OFF. 5. When the on-line editing is used, please reset the conditional contact to initialize the instruction. Explanation: Example: 1. The ten external inputs starting from X0.0 is connected to ten keys which represent 0~9 in the decimal system. When M0 is ON, the instruction is executed. The value that users enter is stored as a binary value in D0, and the output signals are stored in M10~M19.
