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 Protocol 2.3
The iMAC2 Controller uses industry standard EtherNet/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.
Table 3: Maximum EIP Packet Interval
The requested packet interval defaults to 225msec, with a maximum allowed being 400msec.

THE iMAC2 CONTROLLER’S DATA TRANSFER 3
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).

AOIs 4.2
This subsection will describe four RSLogix5000 add-on instructions that have been written for retrieving the EtherNet/IP data from the iMAC2. Instruction parameters and logic (where relevant) is to be described.
4.2.1 iMac_Demux_AOI
This AOI reads in data from the iMAC2 EIP module assembly instance, and distributes it to iMAC2 bug UDT instances and the iMAC2 Controller UDT instance. It uses a network setup lookup table to determine where the bug data needs to be distributed. The AOI parameters are as follows.
The iMac_Demux_AOI InputAssembly input parameter is of the form described earlier in Table 3.1: iMAC2 Controller Input Assembly Instance Data Structure. The AOI logic works in two stages:
In stage 1, the Data, Status, Resistance and ErrCnt data for each of the four consecutive modules
(with the first module node address specified in Start Block Address) is stored to the iMac_Controller DATA, STATUS, RESIST and ERROR arrays. The next block of input assembly data is stored to the iMac_Controller Runtime data. Lastly, the General Buffer and NV Memory data is stored to the GENBUFF and NVM arrays. In time, the data for all bugs (modules) will eventually be stored to the iMac_Controller UDT instance.
In stage 2, the iMac_Network_Config parameter is consulted, and when there is a valid module type,
the node index is used to transfer the DATA, STATUS, RESIST and ERROR information from the iMac_Controller array (at the node index) to the iMac_Modules UDT instances, according to the module type and index. For example, if there is a DI4 module at node address 7, then iMac_Network_Config[7] = 15 (the module type); data will be transferred from iMac_Controller.DATA[7] to iMac_Modules.DI4_Modules[7].DI4_Inputs_IPx, and so on for the STATUS[7], RESIST[7] and ERROR[7] data.
4.2.2 iMac_Clear_Data_AOI
This AOI clears all iMAC2 module and controller instance data. It is intended to be used on first scan only. The AOI parameters are as follows.

4.2.3 iMac_Errors_Assign_AOI
This AOI Assigns iMAC module errors to all types of iMAC modules. It is used within iMac_Demux_AOI as a repeatable function call, to make code more readable and compact. The AOI parameters are as follows.
4.2.4 iMac_Status_Assign_AOI
This AOI assigns iMAC module status bit definitions to all types of iMAC modules. It is used within iMac_Demux_AOI and iMac_Clear_Data_AOI as a repeatable function call, to make code more readable and compact. The AOI parameters are as follows.
RSLogix5000 Program/Routine Usage 4.3
The minimum Program/Routine requirements for getting iMAC2 EtherNet/IP data in RSLogix5000 are shown in Figure 5. They are:
Creation of a Generic Ethernet Module in the RSLogix5000 I/O Configuration tree. This is shown in
Figure 6.
Tags for loading, configuring and storing the iMAC2 data. The tags shown in Figure 5 include:
o Imac:I.Data, the Assembly Instance tag, which is automatically generated by RSLogix5000
when the Ethernet module is created.
o IMAC_Network, the instance of iMac_Network_Config_DT for entering the iMAC2 network
configuration lookup table.
o IMAC_Control, the instance of iMac_Controller_DT for storing the data read from the iMAC2
network, which is the iMAC2 Controller data and the raw modules data.
o IMAC_Modules_all, the instance of iMac_Modules_DT for storing the module data in more
readable and accessible form.
A call to a routine to clear all the iMAC2 EIP data instances. This routine should use the
iMac_Clear_Data_AOI, and need only be called at first scan.
A call to a routine to set up the network configuration for the iMAC2 module network. This routine
should contain instructions for assigning module types at their node addresses; e.g. if a DI4 module (type = 15) is at node address 7, then use IMAC_Network.Lookup_Table[7].Module_Type := 15;
Lastly, a call to an iMac_Demux_AOI instance to read EtherNet/IP data and distribute it to the iMAC2
Controller and Modules tags, based on the iMAC2 Network setup.

Figure 6: Generic Ethernet Module setup for iMAC2 EIP data.
If there is a SIM-G, SIM-G2, SIM-P or SIM-T module in the iMAC2 network, this needs setting up in a more complex way because it takes up 16 consecutive node addresses (or 17 for a SIM-P module). Additional network configuration data is used to specify the SIM-G/SIM-G2/SIM-P/SIM-T unit number and the sub­index of the node within the 16 (or 17) consecutive node addresses. This is better explained with an example of SIM-G data setup as follows:

It has three modules – an AIM module, a DI4 module and an RTD1 module. When running, the web interface shows the online modules as in Figure 8. The modules and addresses are as follows:
iMAC address 10: EOL module. iMAC address 20: DI4 module. iMAC address 28: AIM_FLAGS module. iMAC address 29: AIM_AI module. iMAC address 30: AIM_Power module. iMAC address 40: RTD1_FLAGS module. iMAC address 41: RTD1_Temp module. iMAC address 96: MEOL module.
In RSLogix5000, this network information is entered as follows: IMAC_Network.Lookup_Table[20].Module_Type := 15; // DI4 type IMAC_Network.Lookup_Table[28].Module_Type := 48; // AIM_FLAGS type IMAC_Network.Lookup_Table[29].Module_Type := 49; // AIM_AI type IMAC_Network.Lookup_Table[30].Module_Type := 50; // AIM_Power type IMAC_Network.Lookup_Table[40].Module_Type := 54; // RTD1_FLAGS type IMAC_Network.Lookup_Table[41].Module_Type := 55; // RTD1_Temp_Input type

When the PLC code is running, the iMAC2 data will be retrieved from the EIP instance and will be distributed to the module arrays as needed. For example, the AIM Power module at node address 30 will have its data inserted into IMAC_Modules_all.AIM_Power_Modules[30] - Figure 9 shows the Power supply data (24.22V) and resistance value (93 ohms) transferred correctly.
Figure 9: Node 30 data transferred to the PLC.
Once the iMAC2 data is transferred to the PLC correctly, it can easily be referenced and used in the automation project via aliasing, or via direct tag references such as:
Important_Input_Bool := IMAC_Modules_all.DI8_Modules[7].DI8_Inputs_IP3
