Website: http://www.tmgte.de/.

Looking for an industrial Ethernet slave design which supports several industrial ethernet protocols. Where to find additional information on multi- protocol industrial ethernet solutions for Sitara processors?

There is a multiprotocol TI design guide Multi-Protocol Industrial Ethernet Detection w/PRU-ICSS for Industrial Automation Reference Design at http://www.ti.com/tool/TIDEP0032. The TIDEP0032 shows how to use PRU-ICSS to detect the type of industrial Ethernet by analyzing the frame header.

Can an ICSS support more than one Industrial Ethernet slave at the same time?

This is dependent upon the protocol architecture and physical configuration. The TI Examples for EtherCAT, Profinet IRT, and the Ethernet/IP Adapter are used in a linear or loop configuration. In this configuration two ports (one on each PRU) are used. One port is used to provide upstream interface to the network master and one port is used to connect to the downstream slaves.

In developing a multi-protocol industrial Ethernet slave, which slave industrial Ethernet interfaces can run without using an ICSS?

We recommend when implementing a multi-protocol slave device to use one of the existing designs that are based on the Programmable Real-time Unit - Industrial Communications Engine ( PRU-ICSS). These implementations are provided in the IA-SDK and/or are available from our third party partners. The PRU-ICSS offloads the ARM from cyclic tasks. This reduces the load and real-time requirements on the ARM side while permitting the Sitara to demonstrate best in class industrial communications performance. Running industrial Ethernet over a standard Ethernet MAC depends on the customer requirements as well. Any standard Ethernet MAC support “store-and-forward” Ethernet frame handling only – this means that first the complete Ethernet frame has to be received before any forwarding and/or processing decision can be done by the industrial Ethernet stack. There are classes of PROFINET and EtherNet/IP that allow using standard Ethernet MAC with the store-and-forward mechanism. EtherCAT slave, Sercos III and PROFINET IRT require PRU-ICSS support.

Where to find information on using the ICSS EMAC LLD

The ICSS EMAC LLD developers guide is available at: ICSS EMAC Developers Guide

The ICSS EMAC LLD Debug guide is available at: ICSS EMAC LLD Debug Guide

How many PRU cores are required for running EtherCAT slave in AM335x/AM437x devices?

TI provides firmware for some Industrial communication protocols, such as EtherCAT slave, EtherNet/IP, Profibus and Profinet RT/IRT, as part of AM335x/AM437x IA-SDK package. If users want to use TI’s EtherCAT slave firmware, then, one ICSS (2-PRU cores) is required.

Can we use the MII2 (from the CPSW) as the MAC for industrial Ethernet?

The CPSW interface can be used to support a few Industrial Ethernet cases. The CPSW can be used to support an EtherCAT master. This implementation is available from our third party partners, Acontis Technologies http://www.acontis.com/eng/index.php and 3S-Smart Software Solutions https://www.codesys.com/products.html.

All of the Industrial protocols slave that are provided in PRU-ICSS Industrial Software for Sitara(TM) Processors and SYS/BIOS Industrial Software Development Kit (SDK) for Sitara™ Processors use the PRU based Ethernet configuration. The PRU-ICSS Ethernet with the real time PRU processing capabilities are required for Profinet RT/IRT (conformance class B/C), Sercos III, EtherNet/IP, PowerLink, EtherCAT slave. Although not supported in the Industrial software libraries it is possible to use the CPSW interface to support Profinet RT (conformance class A) and EtherNet /IP (with some constraints)

Can we use any AM335x to support EtherCAT slave or POWERLINK

Both of these protocols specifically require an AM3357 or AM3359 device.

Is there an example that demonstrates a two MAC interface?

IA-SDK 2.1 has an example for two MACs based on PRU-ICSS. This allows for two additional 10/100 ports. The basic example can be improved up with NDK code to show the capabilities of Ethernet communications.

Is there an example that demonstrates a standard Ethernet switch?

In the SYSBIOS Industrial SDK - the Ethernet IP application can be modified to implement a standard switch. The instructions for this modification are available at http://processors.wiki.ti.com/index.php/SYSBIOS_ISDK_Steps_for_creating_stand_alone_switch_example
Additionally, Networking examples are present in the Processor SDK that supports the PRU-ICSS Industrial software

How to test a Profinet system?

In the Industrial SDK there is a document that describes how to test a Profinet slave. The document is located at “SDK installation Directory”\sdk\protocols\profinet_slave\Docs\Molex-TI-AM335x-devkit-How to get connected using STEP7-CPU300.pdf

How to use a UDP socket connection to connect 2 AM437x IDKs

There are two ways to do this using either ICSS Switch functionality or a MAC implementation. In the case of MAC implementation please refer to the Industrial SDK example ethernet_mac. In the case of ICSS switch please use Ethernet/IP application. The steps to create Switch application from Ethernet/IP example are explained at http://processors.wiki.ti.com/index.php/SYSBIOS_ISDK_Steps_for_creating_stand_alone_switch_example.

How are the MAC address set for the PRU-ICSS (Since there is no EMAC present in PRU-ICSS)

Currently it reads the MAC addresses available in the SOC E-fuse. In the case of the AM437x the two entries represent the first and last MAC addresses.

Can we access PRU firmware sources for Industrial Ethernet protocols?

No, IA-SDK package doesn’t provide source code for PRU Industrial protocols firmware due to protocols certification However the TI Design http://www.ti.com/tool/TIDEP0061 provides a Simple Open Real-Time Ethernet (SORTE) protocol that is implemented in PRU firmware that will be available in source code as part of the Processor SDK shortly.

Do some of the industrial protocols require special PHYs?

The TI example industrial Ethernet designs are using the TLK1xx PHYs on the AM3359 ICE v2, AM4379 IDK, and AM57x IDK. The DP83822 is used on the K2G ICE. These are supported in the SYSBIOS Industrial SDK and the Processor SDK and PRU-ICSS Industrial combination. However other PHYs have been used successfully. When migrating to different PHYs some code change will be required. General information on supporting other phys is contained http://processors.wiki.ti.com/index.php/Industrial_SDK_EMAC_Porting_Guide

Can we use PHY for EtherCAT which does not provide high speed output indication?

Yes, Beckhoff provides an excellent Phy selection guide to assist in Phy selection and configuration. https://download.beckhoff.com/download/Document/io/ethercat-development-products/an_phy_selection_guidev2.3.pdf . This document also specifies the LED display requirements for Ethernet phy signals. When the PHY does not have LED_LINK/LED_SPEED signal, the "pr1_mii0_rxlink" and "pr1_mii1_rxlink" signals can be left floating. However, in this case, a program modification is required. In the file {IA_SDK_HOME}\protocols\ethercat_slave\ecat_appl\EcatStack\tiescbsp.c in the function bsp_init, before calling bsp_pruss_mdio_init

Set mdioParamsInit.enhancedlink_enable = TIESC_MDIO_RX_LINK_DISABLE; //This forces MDIO h/w state to a m/c based link detection

Can we use the CPSW to support Ethernet communications and the PRU to support industrial Ethernet communications on the AM335x or AM437x?

The AM335 and AM437x can support up to three Ethernet interfaces. This can be two EtherCAT PRU based interfaces and one CPSW or it can be 2 CPSW and one PRU. CPSW support is available for the AM335x in the SYS/BIOS Industrial Software Development Kit - SYSBIOSSDK-IND-AM335X: (ISDK 1.1.0.x). CPSW support is not presently available in SYSBIOSSDK-IND-SITARA (ISDK 2.1.x). CPSW support is available in the Processor SDK and can be used along with an industrial protocol provided by the PRU-ICSS Industrial.

CCS6.1.3 throws an error when running ProjectCreate.bat for PRU-ICSS-INDUSTRIAL-SW components.

For building/running PRU-ICSS-INDUSTRIAL-SW (http://www.ti.com/tool/PRU-ICSS-INDUSTRIAL-SW) currently it is recommended to use CCS6.1.2. If users want to use CCS6.1.3, then CCS_WORKSPACE_LOC, inside setupEnv.bat, should point to a location that already exist. For example, if C:\Users\alice folder exists then CCS_WORKSPACE_LOC=C:\Users\alice\ccs_workspace_1 can be used.

How to upgrade EtherCAT slave application using FoE?

Users can use TwinCAT for online EtherCAT slave application upgrade. Additional details at: http://processors.wiki.ti.com/index.php/Configuring_TwinCAT_For_AM335x#Online_Application_upgrade_from_TwinCAT. Users need to keep in mind "app" need to be renamed to "ECATFW__". FoE upgrades the "app" in Flash memory.
