Instruction Execution Times
Introduction
This appendix contains several tables that provide the instruction execution times
for DL05 Micro PLCs. Many of the execution times depend on the type of data used
with the instruction. Registers may be classified into the following types:
S Data (word) Registers
S Bit Registers
Some V-memory locations are considered data registers, such as timer or counter
current values. Standard user V memory is classified as a V-memory data register.
Note that you can load a bit pattern into these types of registers, even though their
primary use is for data registers. The following locations are data registers:
Data Registers DL05
Timer Current Values V0 - V177
Counter Current Values V1000 - V1177
User Data Words V1200 - V7377
V7400 - V7577
You may recall that some of the discrete points such as X, Y, C, etc. are automatically
mapped into V memory. The following bit registers contain this data:
Bit Registers DL05
Input Points (X) V40400 - V40417
Output Points (Y) V40500 - V40517
Control Relays (C) V40600 - V40637
Stages (S) V41000 - V41017
Timer Status Bits V41100 - V41107
Counter Status Bits V41140 - V41147
Special Relays (SP) V41200 - V41237
Some instructions can have more than
one parameter. For example, the SET
instruction shown in the ladder program to
the right can set a single point or a range of
points.
X0 X1 Y0 – Y7
SET
C0
Two Data Locations Available
In these cases, execution times that depend on the amount and type of parameters.
The execution time tables list execution times for both situations, as shown below:
SET 1st #: X, Y, C, S
2nd #: X, Y, C, S (N pt)
32.2 ms
14ms+3.1msxN
RST 1st #: X, Y, C, S
2nd #: X, Y, C, S (N pt)
34.4 ms
16+3.2xN
