5-28-9 SET PULSES – PULS(65)
Limitations N and N+1 must be in the same data area.
DM 6143 to DM 6655 cannot be used for N.
Description PULS(65) can be used with the functions listed in the following table.
PULS(65) is used to set parameters for pulse outputs that are started later in
the program using SPED(64) or ACC(––). The parameters that can be set are
the number of pulses that will be output in independent mode, the direction of
pulse outputs from ports 1 and 2, and the deceleration point for pulse outputs
controlled by ACC(––) mode 0.
Since PULS(65) has a relatively long execution time, the cycle time can be
reduced by executing the differentiated version (@PULS(65)) of this instruc-
tion only when it is needed.
Note Refer to 1-5 Pulse Output Function for more details.
Port Specifier (P) The port specifier indicates the pulse output location. The parameters set in C
and N will apply to the next SPED(64) or ACC(––) instruction in which the
same port output location is specified.
Note The bit between 00 and 15 that is output as the contact pulse is specified by
the P operand in SPED(64),
Control Data (C) The control data determines the direction of the pulse output to ports 1 and 2
and indicates whether the number of pulses and/or the deceleration point are
specified in N to N+3. This operand should be set to 000 when an output bit is
specified in P (P=@@0).
