1-1 Features and Functions
CJ1W-CTL41-E The CJ1W-CTL41-E, a Special I/O Unit for CJ-series PLC-systems, is a freely
configurable Counter Unit. Depending on the requirements of your applica-
tion, the specific behaviour of the Unit can be adjusted by changing the con-
figuration settings.
CJ1W-CTL41-E Counters The CJ1W-CTL41-E Counter Unit is equipped with 4 Counters and counts
over a maximum binary range of 32-bits. Accepting input pulse frequencies of
up to 100 kHz allows precise control of fast motions. The Unit’s bi-directional
counting ability allows movement detecting in either direction. Each Counter
of the Unit can be configured independently. The Unit is equipped with 32
Software Outputs, each of which can be linked to Counter events. The Unit
can generate interrupts to the PLC CPU, to allow immediate CPU action upon
Counter events.
Counter Type Configuring the Unit starts with choosing one out of two Counter Types:
• Circular Counter (refer to section 3-2-1 Circular Counter )
• Linear Counter (refer to section 3-2-2 Linear Counter )
By default each Counter is set to Circular Counter. For all Counter Types the
full counting range is available. Circular and Linear Counters can be fully (DM-
) configured according to the application that is to be controlled.
Input Signal Type Depending on the type of input signal your application requires, every Counter
allows a choice out of three input signal types:
• Phase Differential Inputs (multiplication by either 1, 2 or 4)
(refer to section 3-3-1 Phase Differential )
• Up/Down Pulse Inputs (refer to section 3-3-2 Up & Down )
• Pulse & Direction Inputs (refer to section 3-3-3 Pulse & Direction )
Output Control Modes To control the Software Outputs the Unit can be configured in one of the two
following Output Control Modes:
• Range Mode (refer to section 3-5-1 Range Mode )
• Comparison Mode (refer to section 3-5-2 Comparison Mode )
In Range Mode, a configurable number of up to 4 Ranges can be applied to
individual Counters. Every Range can control up to a maximum of 32 Soft-
