details the use of the Ethernet port. For information pertaining to the use of the serial communications
port, refer to the IMACB153 iMAC Controller Serial Communications Manual.
NOTE
The Ethernet port is a read only communications port. The iMAC2
Controller has been manufactured in this way to maintain the SIL
“Proven in Use” statistics of the previous iMAC Controller.

Connecting to the Ethernet Port for the First Time2.2
The iMAC2 Controller’s factory default Ethernet IPv4 settings are as follows:

Default Ethernet IPv4 Settings
IP Address
10.1.1.10
Subnet Mask
255.255.255.0
If the Controller’s IPv4 settings have been changed, they can be restored to the factory default settings by
pressing the iMAC2 Controller’s Ethernet Reset button for 4 seconds (The internal iMAC2 Controller status
LED will turn on solid while the reset button is depressed, after 4 seconds the LED will change to a fast flash
to indicate settings have been reset to default, after which the button can then be released).

The iMAC2 Controller’s Ethernet port settings are not configurable via the HMI; they must be altered using
the iMAC2 Web Interface. The Controller’s web server can be accessed using a one-to-one Ethernet
connection with an Ethernet enabled device. Temporarily configure your device’s Ethernet port as follows:
Figure 3: Updating the Ethernet Port Settings of the Connectable Device
Once the network adaptor of the external device has been configured as shown in Figure 3, connect the
iMAC2 Controller’s Ethernet port directly to your device’s Ethernet port, the iMAC2 Controller should then be
able to be pinged at 10.1.1.10. Once a successful ping has been performed, open a web browser (Chrome
recommended) and enter the iMAC2 Controller’s IP address into the address bar: http://10.1.1.10; the
iMAC2 Controller web pages should load within a few seconds.

EtherNet/IP Protocol2.3
The iMAC2 Controller uses industrystandardEtherNet/IP protocol for exchanging data with compatible
Ethernet devices. The EtherNet/IP protocol is the adaptation of the Common Industrial Protocol to the
Ethernet platform. EtherNet/IP allows both implicit (synchronous) and Explicit (asynchronous) messaging,
with UDP port 2222 being used for implicit messages.
The iMAC2 data transfer is carried out via the following Assembly Instances:
Input Assembly Instance 100: defined by a block of 100 (16-bit) words.
Output Assembly Instance 150: defined by a block of 30 (16-bit) words. (Not currently used).
Config Assembly Instance 50: defined by a block of 0 bytes. (Not currently used).
The requested packet interval is configurable, and to guarantee all iMAC module data is sent to the PLC this
interval needs to be set to a rate faster than the iMAC controller is scanning its connected modules (referred
to as the iMAC Controller’s “linespeed”). The linespeed is set by the iMAC SLP code, and can be configured
in the range from 300 to 1000.
There are three commonly used linespeeds: 300, 500 and 1000. The following table specifies the maximum
EIP “packet interval time” that can be used for each of the commonly used linespeeds.

The requested packet interval defaults to 225msec, with a maximum allowed being 400msec.

THE iMAC2 CONTROLLER’S DATA TRANSFER3
The data transferred over EtherNet/IP is a progressive transfer of the iMAC2 data contained within the
iMAC2 Data Point Table. Each implicit message transfer updates the input assembly instance as follows:

Therefore, module data for four modules is sent from the iMAC2 at each packet time (offset 1 to 16), as well
as controller data (offset 20 to 37), EOL/MEOL module data (offset 38 to 47), General Buffer data (offset 50
to 73) and Non-Volatile Memory data (offset 75 to 98). The Start Block Address at offset 0 specifies the
node address of the first of four modules in each transfer. This Start Block Address is incremented by 4 for
each implicit message transfer. So that data for nodes 0, 1, 2 and 3 is updated at packet time t, then data for
nodes 4, 5, 6 and 7 is updated at packet time t+1, and so on until data for nodes 252, 253, 254 and 255 is
sent (at packet time t+63). Then the Start Block Address is reset to 0, and data for nodes 0, 1, 2 and 3 is
updated again.
Applications requiring iMAC2 data over EtherNet/IP need to take this progressive data update into account.
(This is taken care of in the RSLogix5000 Add-On Instruction described later).

DATA HANDLING –RSLogix5000 APPLICATIONS4
A set of RSLogix5000 user-defined data types (UDTs) and add-on instructions (AOIs) have been
constructed to retrieve iMAC2 data over the new EtherNet/IP connection, for connection to ControlLogix
PLCs. These components will be described here.
UDTs4.1
There are module-specific UDTs, as well as generic UDTs used by the module-specific UDTs. These will all
be described in a logical order.
4.1.1 iMac_SystemStatus_DT
This UDT stores the iMAC2 Controller Runtime System Status bits. It is used by iMac_Ctrl_Runtime_DT. It
has the following members.

Description
RefreshCycle
BOOL
Set by the controller at the end of every refresh cycle (refresh cycle = all 255
module addresses have been scanned). May be cleared by writing a 0 into this
bit using application (SLP) software.
L1ChksErr
BOOL
Set by the controller when a checksum error is detected on L1 fieldbus. May be
cleared by writing a 0 into this bit using application (SLP) software.
L1Ok
BOOL
Set by the controller when a L1 fieldbus scan completes with no errors detected.
May be cleared by writing a 0 into this bit using application (SLP) software.
L2ChksErr
BOOL
Set by the controller when a checksum error is detected on L2 fieldbus. May be
cleared by writing a 0 into this bit using application (SLP) software.
L2Active
BOOL
Set by controller when it detects an active fieldbus from another controller on its
L2 port. Often used to condition the operation of the L2 LED on the controller.
CtrlRelayState
BOOL
Status of the Control Relay. 1 = Energised. 0 = De-energised.
AuxRelayState
BOOL
Status of the Auxiliary Relay. 1 = Energised. 0 = De-energised.
EOL_OK
BOOL
Set by controller when EOL module is being detected on the L1 fieldbus with no
faults, clear otherwise.
EOL_SC
BOOL
Set by controller when the L1 fieldbus is short circuited (R<1000Ω), clear
otherwise
EOL_OC
BOOL
Set by controller when EOL module is not detected on the L1 fieldbus and the
fieldbus is not short circuited, clear otherwise.
EOL_CLASH
BOOL
Set by controller when two EOL modules are detected on the L1 fieldbus, clear
otherwise.
