Introduction

This document specifies the function and performance of the Solartron Metrology Single Conditioning Unit Channel SC1 (no display) and SCD1 (with 6-digit, 7 segment display).
The Solartron Metrology Conditioning Unit Single Channel has a 5-pin DIN female socket to connect to the AX range of Calibrated LVDT or half bridge sensors. A female 9 pin D-type connector outputs Modbus data (RS485) and Analog voltage (±10V 16 bit).
There is a USB C type socket, to power the device and communicate using USB. The USB socket is used to configure the unit and /or to read back data. The amplifier can be configured and calibrated with the sensor using the “SCD1_CalConfig” utility. This can be found within the “Orbit3 Suite”.
The sensor can be conveniently read from the USB port using the Gauge Computer Software (Orbit GCS). GCS also offers mathematical functions and data logging to be performed on the sensor. Orbit GCS can be found within the Orbit3 Suite. Alternatively, the sensor can be read from the USB port using serial commands, see section 7 for further details”.

5.5. Modbus RTU
This device has Modbus RTU capability to allow reading to be obtained. Note: RTU = Remote Terminal Unit.
5.5.1. Modbus Hardware
This uses an RS485 half-duplex style communications interface. Operating in Client/Server mode.
5.5.2. Modbus Settings
Node ID, the address of SC1 on the Modbus network for master device (PLC), by default is set to address 1. This can be set to user preferred address via the Calibration & Configuration utility software (see Configure Digital Data). Also, the baud rate & parity can be set using same method.
5.5.3. Modbus Communications
Supported MODBUS function codes / commands:

  • READ_REGISTER
  • READ_INPUT_REGISTERS

The following commands are implemented (potentially for future use and completeness), but at the moment are not in use, as no address is available for user to write via Modbus. These commands can be activated by defining the MODBUS_WRITE_FUNCTIONS.

  • WRITE_MULTIPLE_REGISTERS
  • WRITE_SINGLE_REGISTER

Unsupported commands:

  • READ_BIT
  • WRITE_BIT
  • LOOPBACK_COMMAND

5.5.4. Modbus parameter Map
Currently only 2 addresses on the parameter map are available for user to be read via Modbus read command.

Modbus Register Start Address| Parameter on the SC1 data map| Application on Modbus interface| Number of Modbus Registers Required| Data Type
---|---|---|---|---
0| SC1_DATA_FIELD_UOM| Returns the current Units Of Measure (UOM)| 1| Enum (Uint8)
1| SC1_DATA_FIELD_PROBE_READING_UOM| Returns reading in the current Units Of Measure (UOM)| 2| Int32

5.6. Analogue Output
Two modes are available:

Mode Functionality Details
Reading An analogue voltage (16 bit resolution). Two ranges:

-10 to +10 volts (16bit DAC) proportional to the sensor position.
Or
0 to +10 volts proportional to the sensor.| For Example, a +/- 5mm sensor:
· -5mm => -10V
· 0 mm => 0V
· +5mm => +10V
Note output slew rate will depend on the amount of filtering applied
Limit Logic| ‘digital output’ that reflects the limits status.
User selectable voltages for inside & outside limits| The “Out of limit” status level can be adjusted from -10 to +10V.
The “In limit” status voltage can be adjusted from -10 to +10V.

Also, set via the Utility – Configure Analogue Outputs. Also, see Output Function
5.7. Probe readings
After Calibration & Configuration, the probe can be read by:

  • The 7 segment display on SCD1
  • Via the USB Serial Interface
  • Via the Orbit Library
  • Via the Modbus RTU Interface

Settings / Data Map

At its heart, the SC(D)1 has a parameter (or data) map that contains all settings and readings. This unit has many settings. The Calibration & Configuration Utility software is designed to adjust common user settings more easily & to avoid having to:

  • Manually set-up the probe & functionality.
  • Using the data map at all

Each individual setting is assigned a parameter number and a value. Some parameters are read-only, some are non-volatile (EEPROM) and some are reserved for Solartron use. This map can be used to:

  • Configure the SC(D)1
  • Obtain Readings

These parameters can be read / written to via the ReadSetting / WriteSetting USB Serial commands.
The table, next, lists all of the available parameters:

6.1. Units Of Measure (UOM)
In order to represent the reading in the desired Unit Of Measure, the following options are available:

Value UOM Details
0 UNKNOWN_NA SC1 does not recognise the UOM
1 mm Millimetres selected. Readings returned in Implied 7 Decimal Places
2-5 Reserved
6 Inch Inches selected. Readings returned in Implied 7 Decimal Places
7-9 Reserved
10 Mil mils selected. Readings returned in Implied 5 Decimal Places

6.2. Reading Mode
The reading can be zeroed or not (absolute). The following modes are available.

Value Reading Mode Details
0 readModeNone SC1 does not recognise the reading mode.
1 readModeZero The SC(D)1 reading has already been zeroed.

Use parameter ‘Reading in UOM Zero’ to obtain actual zero offset.
Note that this can also be achieved using the Switches (SCD1 only).
2| readModeAbsolute| The SC(D)1 reading is NOT zeroed – parameter ‘Reading in UOM Zero’ is set to zero.
Note that this can also be achieved using the Switches (SCD1 only).
3| readModeZero_Applying| Set this to request to zero the to the present reading. Value will alter to readModeZero when complete.
Note that this can also be achieved using the Switches (SCD1 only).
4| readModeAbsolute_Applying| Set this to request to remove the zero from the reading. Value will alter to readModeAbsolute when complete.
Note that this can also be achieved using the Switches (SCD1 only).

6.3. Probe Readings
Probe readings can be obtained in 2 ways:
6.3.1. Via the DataMap – see Settings / Data Map
Readings are sent on request

Parameter – see Settings / Data Map Details
Reading 18 bit Returns reading in counts (Solartron only)
Reading in mm, Returns reading in millimetres – see Units Of Measure (UOM)
Reading in UOM Returns reading in the current Units Of Measure (UOM)

6.3.2. Via the USB Command Protocol
Readings are streamed or on request.

Command – see Supported Commands Details
GetReading Returns a reading in Reading format
StartStreaming Start streaming (at the serial stream rate)
StopStreaming Stops streaming
Parameter – see Settings / Data Map Details
--- ---
Streaming 0=> stream, Non zero => Do not stream

NOT stored in non-vol
Serial Stream Rate| Delay between streamed readings in milliseconds

6.4. Using integers with implied decimal places
To avoid using floating point maths, a 32 bit signed integer is used to represent a binary number with a decimal place – e.g. the reading in Units Of Measure (UOM).
6.4.1. Implied 7 Decimal Places
In most cases, this is represented as a 7 decimal place integer, i.e. 10,000,000 => 1.000000
6.4.2. Implied 5 Decimal Places
However, in certain cases (for larger numbers that would overflow the 32 bit boundary e.g. mils), this uses a 5 decimal place integer, i.e. 100,000 => 1.00000
6.5. Limit Status
When Upper & Lower limits are in use, limit status has the following possible values:

Value Reading Mode Details
0 None SC(D)1 does not recognise the limits set.
1 LessThan Reading is inside limits
2 Between Not used by SC(D)1
3 Greater Than Reading is outside limits
4 Out Of Range Not used by SC(D)1
5 Error Not used by SC(D)1

6.6. Output Function
The Analogue Output has various modes, defined in the AnalogueOutFunction Setting. This has the following functionality:

Function / Mode Name Description
0 Reading -10 to 10V Normal operation of firmware. Analogue output (+ / –

10V) over the calibrated reading range
1| Limits Logic| Output goes high (VLH) outside limits, low (VLL) inside limits
2| Reading 0 to 10V| Analogue output (0 to 10V) over the calibrated reading range

6.6.1. Reading
This will output the reading scaled to either:

  • +/-10V output
  • 0 to 10V output

Note that the slew rate will depend on the Output Filtering Setting
6.6.2. Limits Logic
Two Settings are available for

  • Logic High Voltage (V LH). This can be set to any voltage (in mV) between +/-10V
  • Logic Low Voltage (V LL). This can be set to any voltage (in mV) between +/-10V

e.g. for 5V, Active high, VLH= 5000, VLL= 0
e.g. for 3.3V, Active low, VLH= 0, VLL= 3300

6.7. Output Filtering
This setting averages readings. The more the reading is averaged over, the slower the reading speed becomes. More averaging will provide a more stable reading, but will lead to a slower update / response rate.
Minimal averaging provides a faster response time, but more ‘jitter’ on readings. The user can vary the amount of filtering to suit their application.
6.8. Probe reading direction
The reading can operate in 2 directions from the Probe Direction setting:

Value Reading Mode Details
0 RetractPlus The SC(D)1 reading will increase as the probe tip is retracted

(i.e. probe fully out to fully in = positive)
1| ExtendPlus| The SC(D)1 reading will increase as the probe tip is extended (i.e. probe fully in to fully out = positive)

Note that the analogue output will also be affected by this.

USB Serial Interface

The USB / serial protocol relies on Windows assigning a virtual COM port for the SC(D)1 to the user. Other operating systems (e.g. Linux) should operate in a similar manner (but this has not been tested recently).
The serial protocol accesses various parameters (see Settings / Data Map) from the SC1.
Certain parameters are reserved for Solartron use only and are not accessible to the customer.
In normal mode, the SC1’s USB interface (endpoint) is able to send / receive 64 byte command / replies. It is configured as a USB UART (CDC) configuration, operating at Full Speed (12Mbit).
Once communications are established (see Identifying a SC(D)1), communications can be undertaken in 2 ways:

  • Send Commands & their reply
  • Stream Readings

7.1. Commands
7.1.1. Command Protocol

  • All commands start with a ‘^’ (ASCII)
    • Followed by a command byte (binary)
    • Followed by the Address byte (binary)
  • All command replies start with a ‘>’ (ASCII)

7.1.2. Supported Commands

7.1.3. Other Detail
7.1.3.1.Checksum
This is an 8 bit (byte) 2’s complement checksum = Complement(∑ bytes) + 1;
This is used to provide validation of data when reading a setting (ReadSetting) or Writing a setting (WriteSetting)
For example, using the example for WriteSetting:
To Write the “Output Filtering” (data map index = 24, 2 bytes) to 100, send:
^W\x01\x02\x18\x64\x00\xCC”.

  • Where \x indicates a hexadecimal number
  • ^W in hexadecimal = \x5E\x57
  • Address = \x01
  • Length = \x02
  • Data Map setting = \x18 = 24
  • Value = 2 bytes (LSB first) = \x64 \x00
  • Checksum calculated = \xCC

7.1.3.1.1.Detail
Sum of all bytes = \x5E + \x57 + \x01 + \x02 + \x18 + \x64 + \x00 = \x134 8 bit Complement (NOT) of \x134 = \xCC

7.1.3.2.Error Code
The SC(D)1 returns an error code via USB communications – see USB Serial Interface Commands. This has the following meaning:

  • 0 => No error
  • 1=> invalid Parameter

The requested command parameter is invalid (e.g. incorrect data map setting selected)

  • 2=> Access Denied

The requested command is not allowed (e.g. writing to a read only parameter)

  • 3=> Hardware error
  • 4=> Hardware error
  • 5=> Hardware error

7.1.3.3.Address
This is the binary address (0 to 255) that the ‘module’ to communicates to. Note that:

  • For the SC1-A and SCD1-A, there is only one address (address 1).
  • Reserved for future versions that support multiple modules,

7.1.3.4.Reading format
When a reading is requested, it is returned in an ASCII format. If Binary format is desired, the data map should be read – see Probe Readings via the DataMap
7.1.3.4.1.SI3500
The reading format is designed to be the same as the Solartron SI3500 readout and Orbit ACS (for further information, see ACS manual (503110), section 15.2 – SI3500 COMPATIBILITY PROTOCOL)
Data is sent back as a constant length packet in ASCII format:

7.2. Identifying a SC(D)1
The SC(D)1 devices appear as a virtual COM port.
In order to detect a device (and therefore detect the Com port assigned), two items are checked:

  • Device is a USB com port
  • Device has the correct ‘Bus reported USB device description’ – “SC1-A” or “SCD1-A”
    • In Windows software, the Win32 Device Management object can be used to interrogate this

If these two items are valid, then serial commands can then be applied to attempt communications using the Command Protocol.
On Windows OS, the SC(D)1 shows up in ‘Device Manager’ as shown, next.

SC

Orbit Compatibility

Orbit software is designed to interface to the SC(D)1A to treat it as a controller with a single module (that is internal to it). The module is manually added (via Ping, Notify etc).
Therefore, the SC(D)1 will be detected by standard Orbit software (e.g. Orbit GCS) and will return readings.
8.1. Orbit Library
The SC(D)1 is detected via the OrbitServer.Connect method. Refer to the Orbit software Manual (502989) for more details concerning using the Orbit Library.
