4) Dependency Protocol: If enabled, the Allen-Bradley PLC communication will stop if
communication to the selected protocol is lost.
Real Time Automation, Inc. 13 1-800-249-1612

External PLC Configuration
The bottom area of the Allen-Bradley PLC Configuration page lets you configure up to 5 PLCs.
There are two ways to configure this protocol:
•Auto-Server Mode(Default)
•Manual Mode
NOTE: You may go back and forth between modes, but when reverting from Manual Mode to Auto-
Server Mode, all changes made in Manual Mode will be discarded.
Real Time Automation, Inc. 14 1-800-249-1612

External PLC Configuration: Auto-Server Mode (Default)
While in Auto-Server mode the # of scan lines and the actual scan lines themselves cannot be edited.
Auto-Server Mode looks at the other protocol and then configures the Scan Lines within the PLC to
match. The PLC Tag/File Names and Data Types will be defined after the other protocol is configured.
If the PLC is a CompactLogix, ControlLogix, or FlexLogix, the data will be configured according to the
following rules:
•Any 8 Bit Signed/Unsigned data will be mapped as Sint.
•Any 16 Bit Signed/Unsigned data will be mapped as Int.
•Any 32 Bit Signed/Unsigned data will be mapped as Dint.
•Any 32 Bit Float and 64 Bit Float data will be mapped as Real.
•Any Coils or 1 Bit Binary Packs will be mapped as Bool (1 Bit).
•Any Coils or 8/16/32 Bit Binary Packs will be mapped as Bit Array (32 bit).
•Any String Data Types will be mapped as String.
If the PLC is a MicroLogix, SLC, or PLC5E, the data will be configured according to the following rules:
•Any 8 Bit Signed/Unsigned and 16 Bit Signed/Unsigned data will be mapped as Int.
•Any 32 Bit Signed/Unsigned, 32 Bit Float, and 64 Bit Float data will be mapped as Real.
•Any Coils or 1/8/16/32 Bit Binary Packs will be mapped as Bit Array (16 bit).
•Any String Data Types will be mapped as String.
Regardless of PLC type, the following is also true:
•The Read or Write direction depends on whether it is configured as a Read or Write on the other
protocol.
•If the other protocol exceeds the number of Sint, Int, Dint, Real, Bool, Bit Array, or String Data
Types the Allen-Bradley PLC supports (see limits on webpage), then nothing will be mapped. You
will see the # of Scan Lines remain at 0 and the main page will display the following error:
oTo fix this error, simply decrease the amount of data you configured on the other
protocol so that the max number of Tag/File Name is not exceeded OR call customer
support to increase the limits.
Real Time Automation, Inc. 15 1-800-249-1612

1. For additional PLC’s, click the Add PLC button and follow instructions under Manual Mode for
each additional device.
-Auto-Server Mode only affects PLC 1.
2. The Enable check box should be selected for the device.
3. Enter a Device Label to identify the device within the gateway.
4. Enter the IP Address of the PLC, the Controller Slot (Integrated Ethernet, use Slot 0), and select
the PLC Type. The Controller Slot is the slot where the Controller is located, not the Ethernet
Card being used. These 3 parameters must match the PLC you are communicating to.
5. Select the Comms Mode. Unconnected (UCMM) messaging relies on shared resources to
transfer data to/from the PLC. This could result in message timeouts if there are a lot of devices
fighting for these shared buffers. Connected (Class 3 Explicit) messaging relies on reserved
resources to transfer data to/from the PLC. RTA recommends using Connected.
6. To edit scan lines, you will need to go into Manual Mode.
Real Time Automation, Inc. 16 1-800-249-1612

External PLC Configuration: Manual Mode
1. Click the Edit Scan Lines button to switch from Auto-Server Mode to Manual Mode. Once
clicked the button will read Auto-Configure PLC. The fields under the Scan Lines can now be
edited.
a. When prompted, click OK to confirm mode change or Cancel to remain in Auto Mode.
b. Click OK again to keep current Scan Line settings or click Cancel to discard the current
configuration.
2. For additional PLC’s, click the Add PLC button.
-To remove a device, click the Delete PLC button.
- To copy parameters from a device you have already configured, select the device you wish
to copy parameters from in the Copy From dropdown menu. Then, click the Go button.
Once copied, you can make any changes needed to the device you are adding.
3. The Enable check box should be selected for the device.
4. Enter a Device Label to identify the device within the gateway.
5. Enter the IP Address of the PLC, the Controller Slot (Integrated Ethernet, use Slot 0), and select
the PLC Type. The Controller Slot is the slot where the Controller is located, not the Ethernet
Card being used. These 3 parameters must match the PLC you are communicating to.
6. Select the Comms Mode. Unconnected (UCMM) messaging relies on shared resources to
transfer data to/from the PLC. This could result in message timeouts if there are a lot of devices
fighting for these shared buffers. Connected (Class 3 Explicit) messaging relies on reserved
resources to transfer data to/from the PLC. Connected messaging is recommended.
7. Enter the number of Read Scan Lines and Write Scan Lines.
8. Click Generate Scan Lines to have the read and write scan lines auto-generated for you. If you
need to manually configure the read and write scan lines you can do so after they have been
generated.
Real Time Automation, Inc. 17 1-800-249-1612

Configuring Read and Write Scan Lines
Follow these steps to manually configure Read and Write Scan Lines.
1) Click the View Read Scan Lines or View Write Scan Lines button.
2) Enter the Tag/File Name that is set up within the PLC. This Tag/FileName must exist at the
Controller Scope - not the Program Scope.
-If you wish to start from a point other than the base, add [#] to the end of the Tag/File
Name to specify which point is the starting point.
Example: A tag called “ReadTag” has dimension of 100 in the PLC. By default, we will
start at point 0 of that array. Therefore, “ReadTag” and “ReadTag[0]” refer to the same
point. To start from a different point, such as array index 27, enter in “ReadTag[27]” as
the Tag/File Name in our gateways scan line. This means the gateway will go to
“ReadTag” and start at array index 27.
-If you wish to access a specific bit from any Data Type, you must use the Mapping Page’s
Set Bit math function. You may not use ReadTag/0.0 to access bits.
3) Select the Data Type of the Tag/File.
4) Enter the # of Points you want to move from the PLC Tag/File to the gateway. See the Scan Line
Data Limit section at the bottom of the page for the given max values.
-Example continued: Consider # of points is set to 10. If tag is set as “ReadTag” or
“ReadTag[0]” this will read in array points 0 through 9. If tag is set as “ReadTag[27]” this will
read in array points 27 through 36.
5) Click the Save Parameters button.
6) Repeat for the other direction if needed.
Real Time Automation, Inc. 18 1-800-249-1612

Modbus RTU Slave Configuration
Click the Modbus RTU Slave button to access the configuration page.
1) Serial Port: Select which serial port is being used for communication. This port must be
configured on the Port Configuration page. If it has not yet been configured, it will display
Disabled after the Port descriptions in this dropdown.
2) Enter a Device Label to identify the device within the gateway.
3) Slave Address: This Slave Address must be unique for all Modbus RTU Slave devices on the
RS485 network.
4) Inactivity Timeout: Amount of time the gateway will wait for a Read/Write request before
issuing a timeout.
5) To enable data swapping, select the required Swap Indicator. If the bytes appear in the wrong
order, enable swapping to change the data. This swapping does NOT change Coils and their
ordering inside the Bit Pack.
6) Bit Pack: Select the formatting of the Coil Status/Input Status. Automap will use this packing size
to map coils to/from the other protocol. The bit pack selection here should match that of the
other protocol. The starting address is considered Bit 0 and is the low-order bit.
7) Enable Modbus ASCII: Enable ONLY if you want to communicate using Modbus ASCII. The
Master must support Modbus ASCII.
Real Time Automation, Inc. 19 1-800-249-1612

Modbus RTU Slave Configuration-Data Groups
The bottom area of the Modbus RTU Slave Configuration page lets you configure up to 100 Data Groups
for both Read/Write.
There are two ways to configure this protocol:
•Auto-Slave Mode(Default)
•Manual Mode
NOTE: You may go back and forth between modes, but when reverting from Manual Mode to Auto-
Slave Mode, all changes made in Manual Mode will be discarded.
