Features and Functions
The CS1W-CT021 and CT041 High-speed Counter Units are equipped with 2 and
4 Counters respectively, all able to count over a maximum binary range of 32-bits.
Accepting input pulse frequencies of up to 500 kHz allows precise control of fast
motions. The Unit’s bi-directional counting ability enables detecting movement in
either direction. Each Counter of the Unit can be configured independently. The
Unit is equipped with 4 Digital Inputs, 4 Digital Outputs and 28 Soft Outputs. A
maximum response time of 0.5 ms guarantees high-speed closed loop control of
applications.
Freely Configurable
The CS1W-CT021/CT041, a Special I/O Unit for CS1-series PLC-systems, is a
freely configurable High-speed Counter Unit. Depending on the requirements of
your application, the specific behaviour of the Unit can be adjusted by changing
the configuration settings.
Counter Type
Configuring the Unit starts with choosing one out of 3 Counter Types:
•
Simple Counter (refer to 3-2-1
•
Circular Counter (refer to 3-2-2
)
•
Linear Counter (refer to 3-2-3
)
By default all Counters are set to Simple Counter for which no configuration set-
tings have to be made, enabling every Counter to count pulses directly after the
Unit has been powered up. For all Counter Types the full counting range is avail-
able. 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 that your application requires, for every
Counter a choice can be made out of three input signal types:
•
Phase Differential Inputs (multiplication by either 1, 2 or 4)
(refer to 3-3-1
•
Up/Down Pulse Inputs (refer to 3-3-2
•
Pulse & Direction Inputs (refer to 3-3-3
