Description
• The contents of DM0000 are transferred to the internal register when input relay
0000 is ON.
• The contents of the internal register (DM0000) and the value specified by the
operand ($00FF) are ANDed for each bit and the result (logical product) is input
back to the same register.
• When the operation result is "0", special utility relay 2010 turns ON.
• The contents of the internal register are transferred to DM0001.
• The following shows the case when DM0000 is "$F0F0".
