8-2 Overall Procedure for Using CP1E
Built-in Functions
The overall procedure for using built-in CP1E functions is described in this section.
1
Select the functions to use.
Example: Interrupts, high-speed counter
inputs, and pulse outputs.
2
Set the functions with the applicable numbers
using the CX-Programmer.
Example: Using input interrupt IN3 and high-
speed counter 0, parameters in the
PLC Setup must be set for the fol-
lowing functions.
Refer to Section 7
PLC Setup and 8-3
Terminal Allocations
for Built-in Func-
tions.
• Input interrupts
• Quick-response
inputs
• High-speed counters
• Origin searches
• Minimum cycle time
• Serial communications
3
Write ladder diagrams using the CX-Pro-
grammer.
Example: Permitting interrupts with the
MSKS instruction and program-
ming high-speed counters with the
CTBL instruction.
Example: Stopping high-speed counters.
Refer to A-2 Auxil-
iary Area Alloca-
tions by Address.
Example: Reading the present value of a
high-speed counter.
4
Transfer the PLC Setup and ladder program
from the CX-Programmer to the CP1E CPU
Unit.
5
Once turn OFF the power supply to the CP1E
CPU Unit, then turn ON again.
6
Start the CP1E CPU Unit operation.
