Note 1. The RUN indicator will be lit whenever the counting flag (word n+4, bit 00)
is ON.
2. The external control inputs IN1 and IN2 must be ON for at least as long
as the PC’s cycle time to ensure that they can be accurately read from the
PC.
4-4-2 DM Area Settings
Operating Mode DM word m, bits 11 through 08
The operating mode is set with the mode switch on the front panel. Refer to 1-4
Operating Modes for an overview of available modes.
Control Origin DM word m+1, bits 03 through 10
Control inputs (start, reset, and latch) can be designated as originating from the
connector (control inputs IN1 and IN2) or from the IR area (internal IN1 and IN2).
Designations are as follows:
0: External (connector input)
1: Internal (IR area)
DM word m+1, bits 11 through 08
The gate mode type determines the use of control inputs IN1 and IN2. Refer to
1-4 Operating Modes for details. Designations are as follows:
0000: Normal
0001: Cumulative
4-4-3 IR Area Settings
Word n, bit 01
SET TIME is turned ON to use the sampling time held in word n+1. The new sam-
pling time is effective on the rising edge of SET TIME, unless the counting flag in
ON, in which case the new sampling time is effective after completion of the cur-
rent counting operation.
Word n+1
Set to between 0010 and 9999 in ms.
The sampling time designates the time that pulses will be counted following con-
trol input IN1.
Word n, bit 03 or external connector
Word n, bit 04 or external connector
The setting of the control origin, DM word m+1 bits 03 through 00, determines
whether external signals or IR bits are used as the start, latch, and gate signals.
In cumulative gate mode (CT002 only), IN1 is the reset signal and IN2 the count
signal. Pulses are counted while IN2 is ON. In normal gate mode, IN1 is the
count signal and pulses are counted while it is ON.
