The module has

– Labels that identify the AutoMax DCSNet scanner and remote I/O

– A 4-character scrolling display (XXXX)

– 3 LEDs labelled NET, CLX, and OK to indicate www.cniacs.com network status, connection to the ControlLogix processor, and its own internal status

– A 9-pin D-type connector for connection to a DCS or remote I/O network

– Switches on the top of the module to set the mode of operation, number of drop-downs, and depth of drop-downs

Switches to set network type and node address

The switches on the top of the module must be used to set the network type, dropdown number, and dropdown depth before installing the module.

The two switches on the left set the dropdown depth and the two switches on the right set the dropdown number.

The following table shows how to set the switches for each mode of operation.

For example, to configure the 56AMXN/B as a DCS slave with a dropdown number of 17 and a dropdown depth of 5. set the switches from left to right to 0. 5. 1. and 7.

Any other setting is invalid and causes the module to enter the Fingerwheel Test mode. In Fingerwheel Test mode, the display shows the current switch settings.

It will not exit the thumbwheel test mode until power is removed.

In the Thumb Wheel Test Mode, the 56AMXN/B initially displays ‘Thumb Test Mode’ on the 4-character display, the

The display switch is set for 5 seconds, then the display resumes showing ‘Thumb Test Mode’.

For DCS slave operation, if the air drop number and air drop depth are individually valid but combined produce an invalid melt

If the drop number and drop depth are valid individually, but the combination produces an invalid drop number (e.g., drop number 55.), the module will display the drop number in the 4-character display,

then the module will display an error message on the 4-character display, but will not enter the thumbwheel test mode.

but will not enter the thumbwheel test mode.

Determining Module Slot Location

The following figure shows the slot numbering for a 4-slot chassis. Slot 0 is the first slot

Always the leftmost slot in the rack (first slot to the right of the power supply).

You can use any size ControlLogix chassis and install modules in any slot.

You can also install multiple 56AMXN/B modules in the same chassis. The number of modules the power supply can hold (i.e., the power supply’s rating).

Installing or Removing Modules When the Power Supply is Connected

56AMXN hardware versions prior to O-57677-1 do not support the removal and insertion of modules while powered on.

Hardware versions can be identified by looking for a sticker with part number

O-57677-1 or later stickers (near the serial number – you do not need to disassemble the 56AMXN module.

(You do not need to disassemble the 56AMXN to find the sticker). Modules without stickers are hardware version O-57677 and do not support removal and insertion while powered on.

For modules with hardware version O-57677-1 and above, you can install or remove the module with the chassis powered on if the following precautions are followed.

SCANport Data Link

A data link is a pointer used by some SCANport devices to transmit information to a drive.

The data link allows parameter values to be written when sending logical commands and references to the drive. The data link also allows parameter values to be read when reading logic status and feedback.

SCANport devices that support this feature have a set of parameters for data link configuration.

These are called the ‘data link input’ and ‘data link output’ parameters.

The Datalink feature is enabled by setting the correct switch on the communication module SW3 to ‘Enable’ and configuring the ‘Datalink Input’ and ‘Datalink Output’ parameters in the SCANport device.

Each datalink consists of two 16-bit input words and two 16-bit output words.

By setting the two ‘Datalink In’ (data link input) and ‘Datalink Out’ (data link output) parameters in the SCANport device

Set the two ‘Datalink In’ parameters for this data link to the desired target parameters.

Similarly, by setting the two ‘Datalink Out’ parameters, each of the two output words can be configured to Similarly, the

Each of the two output words can be configured by setting the two ‘Data Link Output’ parameters for that Datalink.

Each Datalink switch on SW3 enables or disables one Datalink.

If a Datalink is enabled, the parameter values set www.cniacs.com in the ‘Data Link Output’ parameter will be transmitted to the communication module.

The parameter values set in the parameter will be transmitted to the communications module, and the data sent by the communications module for that datalink will be transferred to the parameters set in the ‘Data Link Output’ parameter.

If the data link is enabled, the parameter values set in the ‘Datalink Out’ parameter will be transferred to the communication module.

and the data sent by the communication module for the data link will be transmitted to the ‘Datalink In’ parameter.

If the data link is not enabled If the data link is not enabled, the data transmitted to the SCANport device for this data link will be zero.

The data transmitted to the SCANport device will be zero and the communication module will ignore any data sent by the SCANport device.

The communication module will ignore any data sent by the SCANport device.

Function Description

Traverse Function

The 1336 PLUS II output frequency can be programmed to modulate around a set frequency. This can be achieved by setting three parameters to create an inertia compensated delta waveform

– Traverse Period, Maximum Traverse, and P Jump. In surface drive winding applications, the developed waveforms can be used in a traverse drive to electronically perform the traverse function.

The traverse actuator will move the yarn back and forth in a diamond pattern so that the yarn is evenly distributed over the surface of the tube. This pattern must be changed in order to prevent yarn build-up at the same points on the surface. This can be achieved by constantly

continuously changing the traverse speed in a cyclic manner over a specified speed range. Using inertia compensation, a series of distributed diamond patterns can be formed over the entire surface of the tube.

Start-up operation

For applications requiring unattended operation, the 1336 PLUS II can resume operation when power is restored after a power failure.

If the Power On Run feature is activated and the input power supply is disconnected, then when the power is restored

The drive will automatically restart and run at the current commanded speed if all the necessary signals (Enable, Auxiliary, No Stop and Start) are present.

4-20mA Current Loss Option

Many control systems will issue a 4-20mA control signal for the drive to use as a speed reference.

The drive will run at the lowest speed with the 4mA signal and at the highest speed with the 20mA signal.

The drive can also invert this signal to run the minimum speed at 20mA and the maximum speed at 4mA.

Since a minimum signal of 4mA is required, the drive must have a ‘fallback’ command in the event of signal loss (sensor failure or disconnection).

Products

The Bulletin 1402 Line Synchronisation Module (LSM) is designed to meet the needs of manufacturers of three-phase AC generators and power generation systems,

system integrators and users, or for applications where two three-phase systems need to be synchronised with each other.

The module provides the means for automatic synchronisation, load sharing and high-speed power system monitoring.

The Line Synchronisation Module (LSM) is a two-slot 1771 form factor module that fits into a standard Allen-Bradley 1771 I/O chassis.

It has three functions:

1. measures appropriate parameters from two three-phase systems and provides control and error signals for synchronised control of the engine governor.

2. provide an analogue output representing the ratio of the power supplied by the alternator to the alternator output rating;

To read an analogue input representing the ratio of the total system load to the total system capacity;

and provide an error signal to adjust the alternator for proper load sharing based on instantaneous load requirements.

3. act as a multi-function digital power monitor for the system.

These functions provide data and control signals that are transmitted to the PLC-5 through the 1771 backplane.

Synchronisation and Load Sharing Errors

In order to synchronise two three-phase systems without high transient energy transfer, the voltages, frequencies and phase differences of the two systems must match.

Kilowatt load sharing can be achieved by matching the ratio of the power system load to the system capacity to the ratio of the actual alternator power to the alternator power rating.

The LSM provides the following information so that the customer’s system can achieve the necessary control operations.

– Voltage matching error (in units of 0.05%)

– Frequency matching error or slip (in 0.01 Hz)

– Synchronising bus and reference bus phase matching error (in 1 degree)

– Load sharing error (scalar between 0.000 and 1.000)

– Synchronisation status

– Frequency within limits

– Voltage within limits

– Phase within limits

– Synchronisation mode conflict fault

– Phase rotation mismatch fault (3-phase synchronisation mode only)

– No reference bus voltage fault

– No synchronised bus voltage present fault

– Reference bus overvoltage fault

– Synchronous bus overvoltage fault
