Counting functions are required for counting parts or events, grouping objects,
incoming or outgoing flow control, and measuring the lengths or positions of items.
Premium PLCs perform these functions using
TSX CTY 2A
/
4
A
counter modules
which have a counting frequency of 40 kHz maximum. In a Premium PLC
configuration, the number of TSX CTY counter modules must be added to that of the
other application-specific modules (communication, motion control and weighing).
(
See pages 1/10 and 1/19). They are hot-swappable. Counter modules are
characterized by their number of channels:
b
2
channels with downcounting, upcounting and up/down counting for the
TSX CTY 2A
module
b
4
channels with downcounting, upcounting and up/down counting for the
TSX CTY 4A
module
The parameters of these functions are set by software configuration. The modules
take 5 V
c
or 10 to 30 V
c
sensors with solid state outputs (incremental encoders,
proximity sensors, photoelectric detectors) and with mechanical contact outputs (in
this case the counting frequency is limited to 100 Hz).
Description
The front panel of
TSX CTY 2A
(2-
channel) and
TSX CTY 4A
(4-
channel) counter
modules comprises:
1
One 15-way SUB-D connector per channel for connecting:
v
Counter sensors or incremental encoder
v
Sensor power supply
v
Encoder power supply feedback for checking that it is supplied correctly
2
One 20-way HE10 connector for 2 channels for connecting the following for each
channel:
v
Auxiliary inputs: preset, enable
v
Reflex outputs
v
Power supplies for auxiliary I/O and incremental encoders
3
Rigid casing, which:
v
Holds the electronic card
v
Locates and locks the module in its slot
4
Module diagnostic LEDs:
v
Module diagnostics:
-
Green RUN LED: module operating
-
Red ERR LED: internal fault, module failure
-
Red I/O LED: external fault
v
Channel diagnostics: Green CH
p
LED: channel diagnostics available
