Modules.

What is a High Speed Rail counter module?

The module counts pulses using a counter or frequency operating mode.

The count is expressed as "cumulative count" or "frequency." Depends on the mode configured for the module.

You can choose from three Counter modes or one of three modes for the frequency mode when configuring the module. The mode of operation is the choice that determines how to store the pulse count and the action output.

You can manipulate the store of count values (see Chapter 2 for details) module based on user-configured presets and/or

The response time of the activated output is therefore executed at a faster rate than the rate evaluated in the controller.

Configuration labels, these labels will be automatically installed with the module for the first download of the programming software, determine whether

The module interprets the pulse as:

• Cumulative count - the value can be 1... Sixteen million.

• Frequency - positive or negative depending on the direction of rotation

The CamCon 1756-DICAM digital CAM switch unit is designed for the Allen-Bradley ControlLogix 1756 PLC system. It is used in industrial applications where switching operations are repeated on a regular basis. Digital CAM switches are an ideal alternative to mechanical switching units, and they offer additional advantages including a simple installation and adjustment process, repeatable adjustment process, reliability, high-speed switching and speed compensation. A total of 32 status leds are provided on the front panel of the module. Interfaces on the 1756-DICAM CAM switch include the ControlLogix 1756 backplane bus interface and an optional RS-485 interface for testing. There are 24 outputs on the module, which are separated by electrolysis for the ControlLogix configuration. There are 8 inputs on the module, which are also electrically separated. The number of outputs and inputs can be expanded to 200 with external interface options.

1756-DICAM CAM switch supports 1200 programmable cams. Depending on the application requirements, the number of cams can be increased to 4000 or even 10,000. Three data storage options are available, including 16 KB, 48 KB or 128 KB EEPROM. 1756-DICAM CAM switch supports 32,768 programs. The cycle time or switching speed is 70 microseconds and can be adjusted. Delay time compensation can be set to 0 to a maximum of 9999.9 ms. On SSI, the maximum length of the cable between the CamCom 1756-DICAM switch and the measuring system is 300 meters (1000 meters option is also available). The 1756-DICAM CAM switch draws 450 milliamps of current from the chassis backplane at 24 volts DC. At 50% of the switching time, each output has an output current of 0.2 amps and each output has an output current of 0.4 amps. The module has a housing protection rating of IP 20 and an operating temperature range of 0 to 55 degrees Celsius. Module weight is 350 grams.

Pulse meter values can be obtained by using different types of counters and frequency modes. A simple counter only uses input A to count pulses. An encoder uses input A and input B to count pulses. Relationship between

Between the two channels is how the encoder determines whether the count is positive (clockwise) or negative (counterclockwise).

This user manual also details the frequency operation mode

Availability depends on which one your application requires. frequency

It can be calculated in one of three ways:

• Frequency (rate measurement).

• Periodic rate.

• Continuous speed.

All three frequency modes determine the frequency of the input pulse

Counts pulses at user-defined intervals. If the revolution is rotating clockwise, the frequency is positive; In the counterclockwise direction is the decreasing (negative) frequency. For more details on frequency patterns, see page 25.
