1-2 Install the Module

Install the Mounting Base

The wiring base assembly (1734-TB or 1734-TBS) consists of a mounting base (1734-MB) and a removable terminal block (1734-RTB or 1734-RTBS). You can install the assembly, or just the mounting base. To install the mounting base/wiring base assembly on the DIN rail, proceed as follows.

ATTENTION

POINT I/O is grounded through the DIN rail to chassis ground. Use zinc-plated yellow-chromate steel DIN rail to assure proper grounding. The use of other DIN rail material (such as aluminum and plastic) that can corrode, oxidize, or are poor conductors, can result in improper or intermittent grounding.

Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.).

1. Position the mounting base/wiring base assembly vertically above the installed units (adapter, power supply, or existing module).

2. Slide the mounting base down, allowing the interlocki ng side pieces to engage the adjacent module or adapter.

Slide the mounting base to allow the interlocking side pieces to engage the adjacent module or adapter.

OFF by changing the RUN setting. You may find this feature useful during machine setup or maintenance. The default setting for RUN is ON. When you first apply power to the module, the SSI clock output is active. The green LED on the front of the module indicates the RUN status, as well as Bit 1 or Byte 0 in the module status word (produced byte 8, Bit 1; 1 = RUN ON, 0 = RUN OFF).

Data Type This refers to the code type of your SSI sensor. The

1734-SSI module supports Gray and Binary code types. The module default is Gray. You must have the right code type selected so that other module features operate correctly.

SSI Word Length The number of bits in a single SSI word is completely

determined by the SSI sensor. See the manufacturer’s data sheet for the sensor output word size. The word length setting range is 2…31 bits. The default SSI word length is 13 bits.

Data Rate The data rate is the SSI sensor’s communication rate

(bits/s) stated in the manufacturer’s data sheet. The data rate you select at the SSI module equals the approximate frequency of the SSI module’s clock output (the actual measure frequency varies with the SSI word delay time). The maximum data rate that can be used for your application is limited by the transmission line length between the SSI module and sensor. See the SSI sensor data sheet, as well as the 1734-SSI Installation Instructions, publication 1734-IN581, for communication rate versus transmission line length information. The module supports the following SSI data rates: 125, 250, 500 Kbps, 1 and 2 MBps. The module default rate is 125 Kbps.

Gray-to-Binary Conversion The 1734-SSI module can change the displayed SSI sensor

data from Gray to Binary. Change this setting to ON only when using a Gray-code sensor and you wish to read a present SSI value that is proportional to total sensor travel. Gray-code sensor values continuously increase and decrease as the sensor travels in one direction, and do not provide a sense of proportionality. The module default for this setting is OFF.

SSI Word Delay Time This is the time between successive SSI words that are

transmitted by the SSI sensor to the module. The 1734-SSI module features a wide selection of delay times ranging from 16…64,535 µs. The module default delay time is 64 µs. Refer to your SSI sensor data sheet for the recommended delay time. If the sensor manufacturer specifies a value called monoflop time, use that value for the SSI word delay time setting.

SSI Word Filter Control The number of successive, equal SSI data words received

by the module from the SSI sensor in order to update the real-time present SSI data word. Max = 5 successive equal values, High = 4, Med = 3, Low = 2, and Off = the module produces a SSI data word each time a new value is available from the SSI sensor, without the previous value comparison. Adjust the SSI Word Filter Control value when using SSI sensors with the Position Forming time < 0.5 ms, so that you can see SSI sensor data change as the sensor is in motion. Note that changing the default value of 5 (Max) for this parameter is done at the expense of reporting accurate sensor data in an electrically noisy environment.

Publication 1734-UM007D-EN-P - December 20 05

Data Standardization You can remove bits from the right side of the displayed SSI

present value word by setting Data Standardization to ON. This feature can be used as a divide by a power of two, or for data masking. Enter the number of bits you wish to remove in the Trailing Bits parameter (discussed below). The default setting for Data Standardization is OFF.

T railing Bits The number of bits removed from the displayed SSI present

value word if Data Standardization is ON. The range is 0…16 bits, and the default value is 0.

Value Definition

Sensor Resolution The number of steps per revolution for a rotary sensor, or

total number of steps per stroke for a linear or optical transducer. The Sensor Resolution value is not used by the module and is not needed for proper module operation with your SSI sensor. The Sensor Resolution value can be passed to the network master for processing if desired. The range is 1…65,535 steps and the default value is 1.

Sensor Cycles The total number of revolutions for a rotary sensor. If you

are using a linear or optical transducer , the value you should enter for Sensor Cycles is most likely equal to one. Like the Sensor Resolution parameter, the Sensor Cycle value is not used by the module and is not needed for proper module operation with your SSI sensor. Pass the value to the master if needed. The range is 1…65,535 steps and the default value is 1.

Data Latch Define an edge of the sourcing I1 input for storing a sensor

position. The choices are the falling edge of I1 (Off-to-ON), rising edge (On-to-OFF), or both falling edge and rising edge. The default value for Data Latch is OFF. For operation details, see operating feature of Data Latch.

Comparator 1 and Comparator 2 Control

You can compare the incoming SSI sensor count to a stored value, and the module provides notification of the event when the present sensor value equals or exceeds the stored value. The module stores two separate comparator values (1 and 2), governed by separate comparator control values (1 and 2). Using the comparator control parameter, you can set the module to flag the event on an increasing, decreasing, or both (increasing and decreasing) sensor count. The default setting for both of the Comparator 1 and Comparator 2 Control values is OFF. For operation details, see operating features of Comparator 1 and Comparator 2 Control.

Comparator 1 and Comparator 2 Value

Enter your comparator value into these parameters. Comparator values can be obtained by moving your SSI sensor to the position of interest and reading the present SSI value.

and Comparator Features

Data Latch

See the table for a listing of values for DeviceNe t name, RSLogix 5 000 tag, and RSLogix 5000 field name.

SSI sensor positions can be stored with operation of the digital input (I1). The I1 input is sourcing (IEC Type 3 compatible); thus grounding the input turns it ON. The yellow I1 LED on the front of the SSI module also illuminates when the I1 input is ON.

Data Latch DeviceNet Name RSLogix 5000 Tag RSLogix 5000 Field Name

Bit 0 of Status Byte 0 LHON: Input DataLatched LACK Output LatchAck

Input InputStatus

The I1 input is edge-sensitive: the module can react to rising or falling edges of I1. Choosing the falling data latch value provides OFF-to -ON data latching, and choosing the rising value provides ON-to-OFF latching. Choose the Both value if you need OFF-to-ON and ON-to-OFF data latching simultaneously.

With one of the Latch Input modes active, watch the module Status Word (status bytes 0 and 1) for I1 input operation. When I1 i s ON, bit I1 in Status Byte 0 (bit 0 of Status Byte 0) is 1. If I1 is OFF, the I1 bit is

0. When the I1 input is activated corresponding to the Latch Input mode, the current SSI sensor value is stored in produced bytes 4 to 7.

The LHON bit (bit 4 of Status Byte 1) will be set to 1. To unlatch the stored value, toggle (set to 1 for about 0.5 ms, then back to 0) the LACK bit, which is bit 0 of the Master Ack Byte. The Master Ack Byte is consumed Byte 0 sent by the master to the 1734-SSI module. Once the LACK bit is toggled, LHON is set back to 0 and the produced bytes 4 to 7 return to 0 as well. You can also unlatch stored da ta by tu rning the Latch Input parameter OFF through the configuration. The LHON bit returns to 0 as well when the Data Latch is turned OFF through the configuration.

Comparators 1 and 2

Y ou can store two separate four-byte va lues and be notifie d when the SSI sensor attains or exceeds the stored value. Comparators 1 and 2 are mutually exclusive: only one comparator can be active at any given time.

You can set a comparator to trigger on an increasing sensor count, decreasing count, or regardless of sensor direction, by choosing Both for the comparator control value. There are two modes of comparator operation: manual and automatic. The green COMP LED on the front of the module illuminates when a comparator value is reached. The LED goes OFF when comparator reset occurs.

See the table for a listing of values for DeviceNet name, RSLogix 5000 tag, and RSLogix 5000 field name for Manual and Automatic mode.

Manual Mode

Select Manual mode by entering a comparator value and a corresponding control value (increasing, decreasing, or both). If you are using Comparator 2, for example, you notice Bit 7 of Status Byte 0 (C2ST) is 1 when Comparator 2 is active. To reset the comparator, toggle (set to 1 for at least 0.5 ms, then back to 0) the Comparator 2 acknowledge bit, Bit 2 of the Master Ack Byte (CC2).

You can also reset Comparator 2 by turning it OFF through the configuration. Comparator 1 uses Bits 6 (C1ST) and Bit 4 (C1R) of Status Byte 0 for operation. Bit1 (CC1) of the Master Ack Byte is used for reset. Like Comparator 2, you can also reset Comparator 1 by turning it OFF through the configuration.

4-6 Set and Operate Your Module

Automatic Mode

The purpose of the Automatic mode is to provide a means of switching between two comparator values without having to activate each comparator separately through the configuration.

In Automatic mode, only the Both comparator control setting is active for Comparator 1 and Comparator 2. There is no provision to choose between the comparator control settings in Automatic mode.

In Automatic mode, you must first enter values for Comparator 1 and Comparator 2 through the configuration. Enforce bit 3 of the Master Ack byte (SCMP1) by setting it to 1. Make sure bit 4 of the Master Ack Byte (SCMP2) is set to 0 when you enforce SCMP1.

Notice that C1ST is now 1, indicating that the Comparator 1 is active. When the SSI sensor reaches the Comparator 1 value and the C1R bit is 1, enforce SCMP2 by setting it to 1.

Other Module Features

IMPORTANT

Notice that C2ST is now 1, indicating that Comparator 2 is active. Also notice that C1ST and C1R are now 0. When the sensor reaches the Comparator 2 value, C2R gets set to 1. You may now repeat the cycle by enforcing SCMP1 while setting SCMP2 to 0. Cancel Automatic mode by setting both SCMP1 and SCMP2 to 0.

The Module Status word, consisting of Status Bytes 0 and 1, contains information regarding module operati on.

The DEC and INC bits, bits 2 and 3, respectively, of Status Byte 0, indicate sensor count direction as the SSI sensor is in motion. Watch these bits change as the SSI sensor changes direction. If the count is currently increasing, INC is 1. When the count decreases, DEC is 1. If INC and DEC are both 0, the SSI sensor is not in motion, or is moving very slowly. There are two green LEDs (INC and DE C) on the fro nt of the module, which also indicate the SSI sensor count direction.

After setting SCMP2 to 1, set SCMP1 to 0. Setting them both to 0 at the same time cancels Automatic mode.

Publication 1734-UM007D-EN-P - December 20 05

The lower bits of Status Byte 1 provide module troubleshooting information. If the SPF (bit 0 of Status Byte 1) bit is 1, the SSI sensor power provided at the module terminal block is shorted, or the SSI power is not present. This causes incorrect SSI sensor data to be collected by the module.

Set and Operate Your Module 4-7

Major module faults are indicated by the presence of the CCF and CCE bits, bits 1 and 2 respectively of Status Byte 1.If either of these bits is 1, you do not receive correct SSI sensor data. T ry re setting the module with a power cycle.

If either of these bits remain ON, call technical support for further assistance.You can monitor power or major module faults by monitoring a single bit in Status Byte 1; the IDF bit (bit 3 of Status Byte 1). W e recommend that you place the IDF bit in your ladder logic as an indicator of SSI sensor data integrity. If the IDF bit is set to 1 for any of the reasons discussed above, you can quickly switch your system to a safe state for troubleshooting.

Example of Using the 1734-SSI Module with a 24-bit SSI Sensor

The CLK and DATA signals are representative of what you could actually see on an oscilloscope when the module is attached to a SSI sensor in a live system. The SSI module must be configured for a SSI Word length of 24, as well as the proper Data Rate and SSI Word Delay time stated in the SSI sensor specifications.

SSI Word Delay time is approximately equal to a value called monoflop time, as stated by some SSI sensor manufacturers. When configuring the 1734-SSI module, enter the monoflop time value for SSI Word Delay time.

Point A of the CLK signal is a falling clock edge. When the SSI sensor sees the first falling clock edge after a delay period, it knows to latch its current position into a parallel-to-serial converter located in the sensor.

Publication 1734-UM007D-EN-P - December 2005

4-8 Set and Operate Your Module

At point B of the CLK signal is the rising clock edge. The sensor begins to send its serial data to the 1734-SSI module. The module actually starts reading the sensor position data on the next rising clock edge, denoted by MSB in the figure above. MSB is the most significant bit of the data word.

The 1734-SSI module supports only MSB aligne d data. This means that the SSI sensor sends the MSB of its data word first, and the least significant bit (LSB) is sent last. Notice that it takes 25 rising clock edges to read in a 24-bit data word from a 24-bit SSI sensor. A 25-bit sensor needs 26 rising edges and a 13-bit sensor needs 14 edges. Configure the module for the SSI Word Length as stated in the sensor specifications and the module adds the extra rising edge automatically.

The value t

shown in the CLK signal in the figure is the period of the

SSI clock signal and is equal to the inverse of the SSI Data Rate; thus SSI Data Rate = 1/t

bits/second (or communication rate). You can

verify that your module is operating at the Data Rate that set in the module configuration by measuring t

on an oscilloscope and

calculating the Data Rate.

The actual bit values of the current SSI sensor position are shown beneath the Data signal in the figure. Note that a bit value is always the binary (0 or 1) value just before a given rising clock edge. The next binary value is sent by the SSI sensor just after the rising clock edge and is read by the module on the next rising clock edge.

When you group the binary values in sets of 4, starting with the LSB at the right of the DATA signal, and working up towards the MSB, you can calculate the hexadecimal value of the SSI sensor position.

The hexadecimal values are shown in the figure, below the brackets that denote each group of 4 bits. The Present SSI data word for this sensor position would be transmitted by the module as follows: Produce0 = 0x1C, Produce1 = 0x92, Produce2 = 0xAE, Produce3 = 0x00.

Publication 1734-UM007D-EN-P - December 20 05

Produce3 is 0x00 because the 1734-SSI module always sends a 32-bit hexadecimal value and the sensor in this example is 24-bit. The Latched SSI data word, Produce 4 to 7, is similarly transmitted (low byte first) by the module when the data latch is activated.
