FX Series Programmable Controlers Applied Instructions 5

5.7.3 ABSD (FNC 62)
Operation:
This instruction generates a variety of output
patterns (there are n number of addressed
outputs) in response to the current value of a
selected counter, S2.
Points to note:
a) The current value of the selected counter (S2) is compared against a user defined data
table. This data table has a head address identified by operand S1. S1should always have
an even device number.
b) For each destination bit (D) there are two consecutive values stored in the data table. The
first allocated value represents the event number when the destination device (D) will be
turned ON. The second identifies the reset event. The data table values are allocated as a
consecutive pair for each sequential element between D and D+n.
c) The data table has a length equal to 2 × n data entries. Depending on the format of the data
table,asingleentrycanbeonedatawordsuchasD300oragroupof16bitdevicese.g.
K4X000.
d) Values from 0 to 32,767 may be used in the data table.
e) The ABSD instruction may only be used ONCE.
From the example instruction and the data table below, the following timing diagram for
elements M0 to M3 can be constructed.
