Integrated counter channels and counter
modules
Counter functions are required for counting items or events, grouping objects,
controlling input and output flow, measuring the length or position of elements and
measuring speed, frequency or duration. TSX Micro PLCs provide 3 ways in which
these functions of downcounting, upcounting or up/down counting can be performed:
On the inputs of the discrete I/O module located in the first slot of TSX Micro PLCs, or
b Using the counter channels 11 and 12 integrated in TSX 37 22 PLCs, or
b With TSX CTZ counter modules installed in the available slots on TSX Micro PLC
bases.
Maximum number of counter channels permitted
The first 4 inputs of the TSX DEZ/DMZ pppp 28, 32 or 64 discrete I/O module
located in slot no. 1 enable two counter channels to be used.
1 20-way HE 10 connector (or screw terminal block depending on the model) for
connecting:
v Counter sensors or c 24 V incremental encoder for channel 0,
v Counter sensors for channel 1,
v c 24 V encoder power supply.
TSX 37 22 PLC bases have an integral counter interface (2 channels) which can be
accessed via:
1 Two 15-way SUB-D connectors for connecting:
v Counter sensors or incremental encoder for -channel 11,
v Counter sensors for channel 12,
v Auxiliary preselection input,
v Power supplies for auxiliary inputs, sensors and incremental encoder.
The second connector can take the Telefast 2 ABE 7CPA01 wiring system to
facilitate installation.
The TSX CTZ 1A (1 channel) and TSX CTZ 2A/2AA (2 channels) half-format counter
modules have on their front panel:
1 One high-density 15-way SUB-D connector per channel for connecting:
v counter sensors or incremental encoder,
v encoder power supply,
v encoder power supply feedback for checking that this is correctly supplied.
2 20-way HE 10 connector for connecting the following to each channel:
v auxiliary inputs: preselection, counter enable and read,
v power supplies for auxiliary inputs, sensors and -incremental encoder(s).
3 Locking system for fixing the module in its slot.
