  • Page 4: Introduction

    INTRODUCTION The MTL83xC is a temperature (and mV) measuring system. It consists of an MTL838C or MTL838C-MBT and one or two MTL831C modules. See the datasheet EPS830C and installation manuals INM838C and INM831C for these modules for further details. The main interface on the MTL838C which concentrates the data from the MTL831Cs is Modbus RTU (RS485).

  • Page 5: Quickstart Guide

    QUICKSTART GUIDE This quickstart guide is written for an MTL83xC system based on an MTL831C temperature input multiplexer transmitter with an MTL838C multiplexer receiver. Before the actual installation, it is recommended that new users initially set up a simple system on the bench to become familiar with the MTL83xC system. The minimum hardware required for a test system is as follows: MTL831C Analog transmitter...

  • Page 6: Background To The Mtl838C

    BACKGROUND TO THE MTL838C 3 .1 The analog-input multiplexer system The MTL838C is an analog multiplexer receiver that is used with the MTL831C hazardous area millivolt input multiplexer transmitter. The status of up to 32 analog inputs may be communicated from the hazardous area to the safe area via a data highway, comprised of a simple twisted pair - over distances up to 2000m.

  • Page 7: On-Line Configuration

    3 .3 On-line Configuration Configuring the unit via the Modbus master and the network might seem to be the simplest method at first sight, but there are a number of practical difficulties with this configuration technique. This approach means that the user must deal with a number of complex aspects which require a significant investment of the configurer’s time before they are understood fully.

  • Page 8: Interconnection Of The Mtl838C

    3 .6 Interconnection of the MTL838C The MTL838C may be connected to a Modbus host in a number of ways. Two RS485 outputs, Link 1 and Link 2, are provided on the MTL838C. As there are two outputs the unit can either be connected to a single Modbus master, with dual redundancy, or connected to two separate Modbus hosts.

  • Page 9: Slave, Transmitter And Input Addressing

    3 .8 Slave, Transmitter and Input addressing The following discusses the allocation of addresses to the slaves on the Modbus network - including the MTL838C - and the allocation of addresses for the transmitters and inputs connected to each MTL838C. 3 .8 .1 Addressing MTL838C slaves Modbus allows slave addresses in the range 1 to 247 .

  • Page 23: The Mtl831C #2 Tab

    5 .6 The MTL831C #2 Tab This tab functions exactly the same as the MTL831C #1 tab. The only difference is that it contains the configuration data for the #2 MTL831C. The channel numbers are different so the Modbus system can distinguish the two units. MTL831 #1 shows up as channels 1-16 and MTL831 #2 shows up as channels 17-32.

  • Page 24: The Menu

    THE MENU At the top of the MTL83xC Configurator window is a menu that contains the following items: File, Edit, Devices, and Help. Click on the menu name to drop its menu down and then click on the menu item to execute that function. The Menu items are explained below.

  • Page 25: Edit

    The default file name is “Configs.txt” . Change its name to something more meaningful and press the Save button. We recommend keeping the “ .txt” file type so the program can easily access the files. Also, although these are text files which are easily viewed and manipulated by standard Windows software, we do not recommend altering them in this manner.

  • Page 26: Devices

    6 .3 Devices The Devices menu contains functions specific to the MTL83xC devices. The first three are commands to reset the respective pieces of hardware and the fourth item launches the window allowing firmware updates of the connected devices. All three Reset functions send a command to the selected device that tells it to reset itself (firmware reset).
  • Page 27 If a unit is not connected, then the version information is blank (as is the case above with the MTL831C #2). The latest firmware will be available on the Eaton (MTL) website www .mtl-inst .com . If you suspect that the unit has become corrupted (functionally –...
  • Page 28 If any errors occur, they will be displayed at the bottom of the window. If you get an error, try again. If that is unsuccessful, contact Eaton (MTL) for assistance. Notice that update process for the MTL831C will update ALL MTL831Cs connected to the MTL838C.
