Important Notes

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls describes some important differences between solid state equipment and hard-wired electromechanical devices.
Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is acceptable.
In no event will HITACHI be responsible or liable for indirect or consequential damages resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated with any particular installation, HITACHI cannot assume responsibility or liability for actual use based on the examples and diagrams.

Warning!

If you don’t follow the directions, it could cause a personal injury, damage to the equipment or explosion

• Do not assemble the products and wire with power applied to the system. Else it may cause an electric arc, which can result into unexpected and potentially dangerous action by field devices. Arching is explosion risk in hazardous locations. Be sure that the area is non-hazardous or remove system power appropriately before assembling or wiring the modules.
• Do not touch any terminal blocks or IO modules when system is running. Else it may cause the unit to an electric shock or malfunction.
• Keep away from the strange metallic materials not related to the unit and wiring works should be controlled by the electric expert engineer. Else it may cause the unit to a fire, electric shock or malfunction.

Caution!

If you disobey the instructions, there may be possibility of personal injury, damage to equipment or explosion. Please follow below Instructions.

• Check the rated voltage and terminal array before wiring. Avoid the circumstances over 55℃ of temperature. Avoid placing it directly in the sunlight.
• Avoid the place under circumstances over 85% of humidity.
• Do not place Modules near by the inflammable material. Else it may cause a fire.
• Do not permit any vibration approaching it directly.
• Go through module specification carefully, ensure inputs, output connections are made with the specifications. Use standard cables for wiring.
• Use Product under pollution degree 2 environment.

Process Image Map

An expansion module may have 3 types of data as I/O data, configuration parameter and memory register. The data exchange between network adapter and expansion modules is done via an I/O process image data by RIO3 Series protocol. The following figure shows the data flow of process image between network adapter and expansion modules.

EtherCAT Basics

The EtherCAT protocol uses an officially assigned EtherType inside the Ethernet Frame. The use of this EtherType allows transport of control data directly within the Ethernet frame without redefining the standard Ethernet frame. The frame may consist of several sub-telegrams, each serving a particular memory area of the logical process images that can be up to 4 gigabytes in size. Addressing of the Ethernet terminals can be in any order because the data sequence is independent of the physical order. Broadcast, Multi-cast and communication between slaves are possible.

EtherCAT State Machine

The state of the EtherCAT slave is controlled via the EtherCAT State Machine (ESM). Depending upon the state, different functions are accessible or executable in the EtherCAT slave. Specific commands must be sent by the EtherCAT master to the device in each state, particularly during the boot up of the slave.
A distinction is made between the following states:

• Init
• Pre-Operational
• Safe-Operational and
• Operational
• Bootstrap

The regular state of each EtherCAT slave after bootup is the OP state.

Init
After switch-on the EtherCAT slave in the Init state. No mailbox or process data communication is possible. The EtherCAT master initializes sync manager channels 0 and 1 for mailbox communication.

Pre-Operational (Pre-Op)
During the transition between Init and Pre-Op the EtherCAT slave checks whether the mailbox was initialized correctly.
In Pre-Op state mailbox communication is possible, but not process data communication. The EtherCAT master initializes the sync manager channels for process data (from sync manager channel 2), the FMMU channels and, if the slave supports configurable mapping, PDO mapping or the sync manager PDO assignment. In this state the settings for the process data transfer and perhaps terminal-specific parameters that may differ from the default settings are also transferred.
Safe-Operational (Safe-Op)
During transition between Pre-Op and Safe-Op the EtherCAT slave checks whether the sync manager channels for process data communication and, if required, the distributed clocks settings are correct. Before it acknowledges the change of state, the EtherCAT slave copies current input data into the associated DP-RAM areas of the EtherCAT slave controller (ECSC).
In Safe-Op state mailbox and process data communication is possible, although the slave keeps its outputs in a safe state, while the input data are updated cyclically.
Operational (Op)
Before the EtherCAT master switches the EtherCAT slave from Safe-Op to Op it must transfer valid output data.
In the Op state the slave copies the output data of the masters to its outputs. Process data and mailbox communication is possible.
Bootstrap
In the Boot state the slave firmware can be updated. The Boot state can only be reached via the Init state. In the Boot state mailbox communication via the file access over EtherCAT (FoE) protocol is possible, but no other mailbox communication and no process data communication.

CoE Interface

Parameter management in the EtherCAT system

The CiA organization (CAN in Automation) pursues among other things the goal of creating order and exchange ability between devices of the same type by the standardization of device descriptions. For this purpose so-called profiles are defined, which conclusively describe the changeable and unchangeable parameters of a device. Such a parameter encompasses at least the following characteristics:

• Index number – for the unambiguous identification of all parameters. The index number is divided into a main index and a subindex in order to mark and arrange associated parameters.
  • Main index
  • Subindex, offset by a colon ‘:’
• Official name – in the form of an understandable, self-descriptive text
• Specification of changeability, e.g. whether it can only be read or can also be written
•  A value – depending upon the parameter the value can be a text, a number or another parameter index.

Index Range
The relevant ranges for EtherCAT fieldbus users are:
x1000 : This is where fixed identity information for the device is stored, including name, manufacturer,
serial number etc., plus information about the current and available process data configurations. x8000 : This is where the operational and functional parameters for all channels are stored,  such as filter settings or output frequency. 4

Other important ranges are:
x4000 : In some EtherCAT devices the channel parameters are stored here
(as an alternative to the x8000 range).
x6000 : Input PDOs (“input” from the perspective of the EtherCAT master) x7000 : Output PDOs (“output” from the perspective of the EtherCAT master)

Communication Objects

• This value can be changed depending on the configuration of expansion modules ** G-BUS Status
  • Normal Operation : 0x00
  • Communication Fault : 0x02
  • Configuration Failed : 0x03
  • No Expansion Module : 0x04
