14. Special registers for flags and relevant settings:
Flag Function
M1150 DHSZ instruction in multiple set values comparison mode
M1151 The execution of DHSZ multiple set values comparison mode is completed.
Special D Function
D1150 Table counting register for DHSZ multiple set values comparison mode
Program Example 4:
1. Program Example 4 is only applicable to ELC-PV series.
2. DHSZ and DPLSY instructions are combined for frequency control. If
D
of the DHSZ
instruction is a special auxiliary relay M1152, the present value in the counter will be able to
control the pulse output frequency of DPLSY instruction.
3. In this mode,
-
S
1
: starting address in the comparison table.
S
1
can only use D registers which can utilize
the index registers E and F. Once this mode is enabled,
S
1
will not be allowed to change
even if E and F change.
-
S
2
: the amount of data in the group to be compared.
S
2
can only be a constant value K1 ~
K255 or H1 ~ HFF and does not support the index registers E and F. Once this mode is
enabled,
S
2
cannot be changed. If
S
2
is not within its range, error code 01EA (hex) will
display and the instruction will not be executed.
-
S
: high speed counter number (designated as C241 ~ C254).
-
D
: Designated mode (determined by M1152)
4. This mode can only be used once. For PV series, this mode can only be used with the
hardware high speed counters C241 ~ C254. Enter the values in every register in the table
before executing the instruction.
5. When this mode is enabled, the ELC will first acquire the values in D0 and D1 as the target
values for the first comparison section. At the same time, the index value displayed in D1152
