The EMIT Interface Module (EIM) provides an 8” touchscreen display and communication hub for any one module, or multiple modules, connected to the Controller Area Network (CAN) of the EIM. Modules connected to the EIM will automatically populate as buttons on the System Menu screen (Pg. 0) of the display. Selecting any of the module buttons allows for direct interaction with the respective module.
Other functions not directly related to module interaction include the system run signal trigger, security passwords and access, timer management, alarms, date and time, sensor data logging, and MODBUS communications.
The enclosure of the EIM was designed to be installed either externally using the faceplate and the base or within a panel using only the faceplate. If mounting externally, the EIM can accommodate the mounting of any one module within the base of the enclosure.

Custom Modbus Map
Background
The EIM contains the sole modbus (RS-485) connection for the entire system. However, each module's data is requested with a unique ID. Additionally, each module has a large number of registers, and for a given application only a small number are actually needed.
The EIM contains the feature where a custom modbus map can be uploaded which contains a list of target registers that are reassigned a new register number, and are moved to the EIM's modbus ID. This allows for a single request to pull the exact group of data that is needed.
Downloading the old Modbus Map File
On the EIM, navigate to "System Settings/Utilities" followed by "MODBUS".
*Insert Image*
On this page, select the button "Choose..." after "Custom map".
Insert a USB drive into the back of the EIM. Click the button "Download Current Map". Wait 10-20 seconds or until after the status says "Complete". A file customModbusMap.csv should now appear on the USB drive.
Editing the Modbus Map File
The Modbus map file, now on the USB, can be opened in Excel for editing. This file starts with one example row.
*Insert Image* Start filling in the sheet with the registers that are needed. For each row, the columns will contain:
- Column A, "New Target Register": This column contains the new register that will be used by the external SCADA system to fetch this data value. In general, this column will start at 30001 and each subsequent row will be the next value.
- Column B, "Source Module": Put the source module number in this column, using the key in the first row.
- Column C, "Source Register": Put the source register for the data required
- Column D, "Comment": This column is ignored by the software. Any text can go here
An example table filled in might look like this:
Example
*Insert Image*
In the above example, a SCADA request to the EIM ID for register 30001, qty10, would return the above 10 registers in a row.
Uploading the new map
Once the above step is complete, save the file (keeping the format as csv). Put the USB drive back in the EIM and return to the custom modbus map screen. Now, click "Upload New Map From USB". After the upload is complete, restart the EIM and test out the new map.
Datalogging
All of the sensors on a given module are logged at all times at 1 minute intervals. These logs can be viewed from the Datalog View page (Pg. 75) and downloaded or deleted from the Datalog Files page (Pg. 75). The files automatically roll over, and store around 1 month of data.
Note: for long-term compliance logs, which are stored and downloaded elsewhere, see the article "EMD Compliance Log".
DATALOG VIEWING
The Datalog View page (Pg. 75) can be used to look at the logged sensors of different modules. This page is accessed from the EIM Home page by clicking on “Data Logging”.
*Insert Image*
Datalog View Page
The datalog viewing page can show up to two datalog items at once. To pick a sensor to graph, click on one of the two “Item” buttons. On the Sensor Selection page (Pg. 76) choose a module from the dropdown list then a sensor to graph.
The graph can be expanded/retracted in time using the buttons below the graph. The graph can show from 1 hour of data up to one month. This can be used to recent operation and general trends over time.
Selecting a spot on the graph will put a vertical cursor on the graph that will show the exact value of the one or two sensors displayed at the time of the cursor.
DATALOG FILE MANAGEMENT
The Datalog Files page (Pg. 9) can be used to download or delete data logs. To access this page, click “Datalog Settings / Download Datalogs“ from the Datalog View page, or from the system home screen click “System Settings / Utilities” then “Datalog Files”.
The sensor will be recorded to a file labeled “Datalog_[EIM serial number]_[module].csv”.
DOWNLOADING THE LOGS
Datalogs are accessible via USB and are downloaded according to the following procedure:
Insert a USB flash drive into the port labeled, “USB A” on the reverse side of the EIM displayWhen the EIM recognizes a valid USB drive is ready, the button labeled, “Download All Logs” will be enabledSelect the “Download all Logs” button to download the files to the USB flash drive
- The USB Status will first change the text to “Downloading” and then “Complete” when the file is downloaded successfully
- The download operation will copy currently logging files and any old zipped log files.
After the button reverts back to "Save to USB", the USB flash drive can be removed
The datalog files will remain on the EIM and continue to be logged to after downloading
DELETING LOGS
Selecting “Delete All Logs” will delete all logs on the system. This might be desireable when a unit is moved or restarted after a long period of downtime to start with fresh data.
System Settings / Utilities Pages
The "System Settings / Utilities" Page, accessed from the EIM home screen, contains several back pages for system settings. A description of each is below, or a reference to another article if it exists.
*Insert Image*
About
The About screen (Pg. 4) displays the serial number, hardware version, and software version of the EIM and each module connected to the EIM.
Touchscreen Calibration
The touch screen can be re-calibrated if it is determined that button selection appears to be offset from what is displayed on the screen. To calibrate the touch screen:
- Enter Engineering security access mode
- Navigate to the About screen (Pg. 4)
- Select the “Calibrate Touch Screen” button to start the calibration application
- Very carefully, use quick motions to touch each crosshair as they appear on the screen
- After the calibration, the screen will return to the About screen (Pg. 4) and display a confirmation box that must be accepted
- If the confirmation box is not accepted, the touch screen will omit the new calibration data
For accuracy when selecting the crosshairs, it is recommended that you use a stylus, such as the blunt end of a pen, rather than using your finger.
Use caution not to double tap or select each crosshair as it will result in a bad calibration. The best method to not double tap is to select the crosshair in one quick motion.
Go To Page
The "Go To Page" screen can be used to navigate to a page by the page number
Software Update
The "Software Update" page is used to update the software on the EIM. To use, insert a USB drive with the software update into the EIM, and click "Start Update".
Clean Screen
The "Clean Screen" page shows a blank screen so that the touch screen can be cleaned with a cloth without pressing any buttons.
Main Help
The main help button goes to the help module of the EIM. This is the same as the "Help" button on the EIM home screen.
MODBUS
The "Modbus" page is for setting up the Modbus connection. It is discussed more in-depth in the article "ETS Modbus RTU"
Config Files
The "Config Files" page can be used to save or load settings from one EIM to another. To use, insert a USB drive and click "Write" for a module or all modules. Then take the USB drive to another unit and use the same screen "Read" button to read the settings and use them on the new unit. This can speed up setup times.
Reset
In Engineering security mode, the system can be reset to the factory default values within the Reset screen (Pg. 5) of the EIM. Press the “Reset AFRC, EMD, EIM” button to reset those modules to factory defaults. Press the “Reset ICM” button to reset the Ignition to factory defaults. After reset the Ignition will be in “Configuration Required” state until ignition setup is completed.

Ethernet
Overview
Some EIMs have an ethernet port on the back that can be connected to a customer network. The following serial number ranges have an ethernet port:
- 1000 - 1899
- 3203 and newer
The following functions are currently supported by the ethernet port:
- Modbus TCP (EIM Versions 1.89 and later)
Other functions, such as file transfers and remote web access, may be supported in the future.
This page covers the setup of the ethernet port.
Ethernet Setup Page
If the EIM has an ethernet port, and if the kernel version has been updated to support ethernet, a page will be available to setup the IP Address. This page will be found from the System Menu at "System Settings" -> "Ethernet Port". The button will only show up if the kernel and software support ethernet.
This page appears as follows:
*Insert Image*
There are two IP address setup options:
- DHCP: This option will cause the port to request an automatic address. The current address can be seen under "Port Status"
- Manual: This option causes buttons to pop up allowing manual entry of the IP Address, Gateway, and Subnet Mask. If an address is entered in this way, the address must be properly covered by the gateway for "Submit" to accept the settings.
Separately, there is a setting for the Modbus/TCP port. If a different port is needed than the default port, it can be entered here.
After choosing the settings, select "Submit". If the page validates, the network port should update. Sometimes a power cycle may be required.
Security Key
Background
For EIM versions 1.98 and above, a special USB security key can be optionally used to lock out the "Engineering" password level of the EIM. The also DCT has very similar functionality with the same key.
The key part number is 20221-0001 -- USB SECURITY KEY F/ ETS, and can be ordered from EMIT.
The functionality is as follows:
Security Key Not Enabled
-EIM Security operates normally with passwords
Security Key Enabled
-With the security key not inserted, the user can only use 'Operator' or 'Setup' (with setup password) levels of the EIM
-With the security key inserted, the user can get to all three password levels
The security key itself can be used as a normal usb flash drive for storing files if desired- it can even be re-formatted. The security information is in un-partitioned space.
Enabling the Security Key Mode
A special USB security key (or keys) are obtained from EMIT. The key is the same for all EIMs. After inserting the key, the following dialog will automatically popup about 10 seconds later.
*Insert Image*
If "Change EIM to 'Key Required'" is selected, the EIM will change to 'Key Required' mode. Once in this mode, the key will be required to enter Engineering.
If the EIM is configured to 'Key Required' mode, the dialog will look like this when the key is inserted.
*Insert Image*
If 'Close Window' is selected, the access level can still be changed between operator, setup, and engineering if the different passwords are entered, as long as the key is in. As soon as the key is removed, the access level will return to operator, and 'engineering' level will be inaccessible. As seen in the above dialog, the 'Key Required' mode can also be turned back off with the key in.
If they EIM is in the 'Key Required' mode and the key is not inserted, the following error appears if the 'Engineering' password is entered.
*Insert Image*
Shutdown Logs
Beginning with EIM version 1.94, the EIM will save a log of sensor data for the previous 10 shutdowns, whether the shutdown was a fault or not. As new shutdowns occur, the oldest logs will be deleted so that there are never more than 10 logs.
These logs can be viewed, graphed, and downloaded (to view in Excel (R) ) just the same as the normal alarm logs are. However, there are two benefits of these logs over normal alarm logs:
- Sometimes a unit will be reset (and the alarm log cleared/deleted) before the shutdown is more thoroughly investigated. Since the last 10 shutdowns are saved, they can be still later viewed even after the alarm is cleared.
- Sometimes a unit will have a normal stop, in which case there is no alarm or alarm log, but a user may still want the shutdown data
The shutdown logs are found by selecting "Recent Shutdown Logs" on the EIM Alarms page.
*Insert Image*
EIM Alarms page- Button in lower-right shown to access recent shutdown logs
After selecting the button, a list of the last 10 shutdowns is shown.
*Insert Image*
Previous 10 shutdowns
Selecting one of the shutdowns from this list will bring up the shutdown event.
*Insert Image*
Individual shutdown event
Similar to normal alarm logs, a USB drive can be inserted on this screen to download the one minute datalog of the sensors before this shutdown. Selecting the graph allows for graphing of other sensors during the logged period.
Modbus Temporary Disable
Starting with EIM software version 2.00, the modbus can be temporary disabled during a PM to prevent inaccurate callouts during the maintenance. The system will automatically re-enable itself after a time period in case the user does not remember that modbus has been disabled.
Using Modbus Temporary Disable
To use, go to the MODBUS screen under "System Settings". If in "Engineering" password level, the disable button will be shown on the right.
*Insert Image*
After clicking 'Disable...' a confirmation dialog will come up. If 'Yes' is selected to disable, the number of hours will be asked.
*Insert Image*
The system will not respond to any modbus requests (either over serial 485 or TCP/Ethernet) until the timer expires, or the user manually re-enables the port, whichever comes first.
*Insert Image*
If the port is disabled, and the 'Disabled' button is selected, a dialog will ask the user if Modbus should be re-enabled immediately. Otherwise the timer will run out normally and re-enable automatically. The enable time is saved to disk, so the system can be power cycled multiple times and it will not affect the enabling.
Note: If the clock is changed during the disable period, it may clear the disable timer.
