9.3 MENU SCREENS The MENU Screens are used to set up the SI100 and SI200 operating modes. Some of the menu screens require numbers to be entered. Use the ◄ and ► to move to the digit required to be adjusted and use ▲ to increment and ▼ to decremented. The number will be increased or decreased by the magnitude of the digit selected, see below 1000 1/10...
As well as the menu items shown in the above diagram, the ConfigProbe(s) menu also includes the 'Units' parameter. This defines the Units Of Measure input readings from modules are converted to. Can be configured for MM, Inch or Mil. Note: Only 'MM' type input modules are converted, AIMs (input types of Volts, Current or Temperature) will not be converted.

displayed along side the relevant channel on the display. To maintain backward compatibility, a Channel UOM configured to “SysUnits” (which is the default setting) will revert to displaying the units as indicated by the original SysUnits parameter (MM, Inch or Mil). This facility allows for computed channels or rescaled modules to be shown with real-world Units Of Measurement.

10 SECURITY LEVELS The SI100 and SI200 products have functions that can be set using different levels of security passwords. The default level on power on is level 0. The table below indicates the functions available at different security settings. This feature allows the SI100/200 to be set up by a technician and blocks an operator from changing any parameter settings.
11 OUTPUTS The SI100 and SI200 have three digital outputs. These can be connected in various ways and either powered from an internal 5V supply or an external supply.

16 MODBUS BASED SERIAL COMMUNICATIONS PROTOCOL 16.1 INTRODUCTION The SI series of products support the Modbus communications protocol. More information regarding the Modbus protocol can be found online at www.modbus.org, with the full specification downloadable here: - http://www.modbus.org/docs/Modbus_Application_Protocol_V1_1b.pdf Modbus Communications can be performed over a number of hardware layers including RS232 (single point-to-point communications) and RS485 (multi-drop network communications).
16.2.2 Modbus Unit ID Each Modbus message contains a Unit ID (address), the servers listen to the Modbus communications and if they hear a message containing their UnitID they accept this message and respond. The SI100 and SI200 can have their address set in the COMMS menu.
Please refer to the example below for how an Integer value can be interpreted with decimal place precision. Integer Decimal Place Inferred Value Position value 123456789 123456789 123456789 12345678.9 123456789 1234567.89 123456789 123456.789 123456789 12345.6789 123456789 1234.56789 Parameters can also be ‘signed’ or ‘unsigned’. However, Two’s Compliment negative mathematics is always employed for signed values.
16.2.5 Slave Unit Responses Each and every Slave type unit on the network receives every message transmitted onto the network, so it first checks the ‘Node Address’ part of the message, if it finds a match with it’s own configured Slave/ID/Node address, it will then process the whole message by first checking the ‘Checksum’, which is a value used together with a known algorithm to verify the content of the message is uncorrupted and valid to process.
16.2.6 Modbus Function Codes Supported by SI Products Within the Modbus specification, there are a number of Function Codes, not all of which are implemented by the SI Series of products. The table below shows the full list of Modbus Function Codes together with the Function Codes supported by the SI series. Function Description SI Supported...
16.2.7 Parameter Types The SI series of products support the following parameter types: - Type Registers Details consumed UINT16 Unsigned 16-bit value SINT16 Signed 16-bit value UINT32 Unsigned 32-bit value SINT32 Signed 32-bit value SINT64 Signed 64-bit integer. Note: Usually within the SI series these are used with an inferred six decimal places.
The Orbit ACS Modbus Parameter Map is Document “503116 Orbit ACS Modbus Parameter Map – SI100SI200.pdf”, or “503166 Orbit ACS Modbus Parameter Map – SI400.pdf”, available on the Solartron Metrology Web Site. The table at the bottom of the file shows descriptions for enumerated values. 16.2.9 ACS, Modbus Floating point In order to provide 32 bit floating point type data for parameters, the ACS products provide a floating point interface to any parameter by way of an address offset.
17 MEASUREMENT RESOLUTION, AVERAGING AND BANDWIDTH The Orbit ACS has the ability to set the probes into three resolution options, 14 bit, 16 bit (default factory setting) and 18 bit. The table below shows the best resolution (1 bit that is theoretically possible) with different probe measurement ranges. Range mm Resolution µm (18 bit) 0.00...

20 SI400 APPENDIX This sections describes the differences between the SI100/SI200 as described in this document and the operation of the SI400 unit. 20.1 SI400 SUMMARY The SI400 is a device that can accommodate up to four channels, and as such does not provide the measurement computation facilities (A+B, A+B/2, A-B etc) that the SI100/SI200 provide, as the number of possible computations for a four channel device is prohibitive.
20.2.2 Screen 3 Screen three on the SI400 shows all four channels, with a value and chart only; as per below diagram: - 503110 - Orbit ACS Manual Issue 9 59 of 63...
20.3 SECTION 9.2 - SI100 AND SI200 ACTIONS The SI400 actions differ from that of the SI100 and SI200 because the computation methods provided by the SI100 & SI200 are not supported on the SI400, therefore the SI400 actions are used to control the resetting of Max-Min for any/all of the channels. The SI400 actions are therefore as shown in the table below: - ACTION DESCRIPTION...
