  • Page 7: Introduction

    1.1 General 1.1.1 Introduction The Model 9046 Intelligent Temperature Scanner is a 16 channel modular scanning system designed to operate in harsh environments, such as turbine engine test cells. It uses an Ethernet TCP/IP or UDP interface and has the same mechanical footprint, power and interface connector, and front panel LED indicators as the Model 9116 Intelligent Pressure Scanner.

  • Page 8: Physical Description

    The direct wire connection is the most economical, and the most accurate, as it eliminates one thermocouple junction and its attendant potential for errors. The Model 9046 has the same mounting footprint as the PSI NetScanner family of pressure scanners. It is approved for operation in an ambient temperature environment from –30 to +70 degrees Centigrade.

  • Page 9: Theory Of Operation

    Pressure Systems, Inc. Model 9046 User’s Manual For operation, the Model 9046 only requires 18 to 36 VDC (i=200mA), and the appropriate Ethernet interface. 1.1.3 Theory of Operation The Model 9046 is a 32 channel analog multiplexer, controlled by a microprocessor. It communicates over an Ethernet TCP/IP or UDP interface.

Vb is returned as cold junction temperature. Thermocouple Va is the thermocouple voltage. Vb is the cold junction reference voltage and is saved to be used in cold junction compensation calculations.

    Model 9046 module before such commands can be sent to the module. Finally, there are a few special UDP/IP commands listed that can be sent to a Model 9046 module without a valid TCP "connection" having to be established. These commands can be sent even if the module currently has no TCP address assigned to it.
  • Page 37 A few commands have a fixed format for sending or returning data, which is stated explicitly in its command description. The Model 9046 has several special datum values it returns when a particular E. U. datum is out of range, or was calculated incorrectly. Such values vary with the Sensor type of any channel.
  • Page 38 Pressure Systems, Inc. Model 9046 User’s Manual The individual description of each command follows immediately. Each command has a functional title (and operation code), followed by a short text description. Next, there is a formal definition of the command format and its response, followed by a more detailed text discussion.

    Model 9046 User’s Manual 5.2 No Operation (Command ’A’) Purpose : This command has no internal module effect. It is used as a simple method to verify proper communications to the Model 9046 module. Command "A" ’A’ is the operation code.

    Pressure Systems, Inc. Model 9046 User’s Manual 5.3 Reset (Command ’B’) Purpose : Instructs the module to reset internal operating parameters, and to set all internal control variables to their default "reset" state (see description below). The current TCP/IP socket connection will remain open.

U. data from all channels of the module as fast as possible. Data is returned directly in its native internal (IEEE single-precision float) binary form (i.e., as for format code 7 in other commands).
  • Page 46 Pressure Systems, Inc. Model 9046 User’s Manual NUSS does not use this command normally. You may execute it manually via the ’Execute Commands’ or ’Execute Script’ functions Note of NUSS - though this should be avoided if NUSS is currently operating the module via other NUSS functions.

  • Page 47: Define/Control Autonomous Host Streams (Command 'C')

    If data streams are defined to occur at high scan rates, then each data scan received by the host must be processed and disposed of Note in a timely manner. Model 9046 modules are capable of generating autonomous data streams faster than some "slow" hosts (or limited software, including NUSS) can absorb.

  • Page 49 200Hz even if the requested output is 100Hz or less. Because the default Scans-Per-Average option is set to 64 (default) in a Model 9046, only a 10Hz scan rate is normally achievable, however, unless the Scans- Per-Average option is reduced.
  • Page 50 Pressure Systems, Inc. Model 9046 User’s Manual 5.7.1 Command ’c’- Sub-command Index 00: Configure a Host Delivery Stream This sub-command is used to configure the principle parameters of each of the three possible concurrent host delivery streams, one at a time. Following this configuration phase, the particular stream (1, 2, or 3) or all streams (0) may be started, stopped, altered, or undefined, with other sub-commands.

Model 9046 User’s Manual When the hardware trigger is used to synchronize stream scans ( sync = 0), it is assumed that the user would prefer to also synchronize internal data acquisition cycle. For this reason, when a stream utilizing hardware trigger is started, the module firmware switches out of the free- running continuous data acquisition mode described earlier.

    Pressure Systems, Inc. Model 9046 User’s Manual 5.7.3 Command ’c’- Sub-command Index 02: Stop Stream(s) This sub-command is used to stop (or temporarily suspend) the delivery of any previously started host stream in a module, one at a time or all together, whether the stream was unbounded or bounded.
