Safety Information

Important Information

NOTICE

Read these instructions carefully, and look at the equipment to become familiar with

the device before trying to install, operate, or maintain it. The following special

messages may appear throughout this documentation or on the equipment to warn

of potential hazards or to call attention to information that clarifies or simplifies a

procedure.

DANGERDANGER indicates an imminently hazardous situation, which, if notavoided, will result in death or serious injury.

WARNINGWARNING indicates a potentially hazardous situation, which, if notavoided, can result in death, serious injury, or equipment damage.

CAUTIONCAUTION indicates a potentially hazardous situation, which, if notavoided, can result in injury or equipment damage.

This is the safety alert symbol. It is used to alert you to potential

personal injury hazards. Obey all safety messages that follow thissymbol to avoid possible injury or death.

The addition of this symbol to a Danger or Warning safety labelindicates that an electrical hazard exists, which will result in

personal injury if the instructions are not followed.

WARNINGLOSS OF CONTROL

The designer of any control scheme must consider the potential failure modes

of control paths and, for certain critical control functions, provide a means to

achieve a safe state during and after a path failure. Examples of critical control

functions are emergency stop and overtravel stop.

Separate or redundant control paths must be provided for critical controlfunctions.

System control paths may include communication links. Consideration must be

given to the implications of unanticipated transmission delays or failures of the

link.*

Each implementation of a Magelis XBTGT, HMISTO, HMISTU, XBTGH,

XBTGK, XBTGC, iPC, and XBTGTW must be individually and thoroughly tested

for proper operation before being placed into service.

Failure to follow these instructions can result in death, serious injury, orequipment damage.

Target Machine Serial Interface

Use the following serial interface diagrams in combination with the cable diagramsin Section 3 to wire connections between the target machine and external

equipment.

Magelis iPC Series (Smart, Compact, and Flex) and XBTGTW Series

The iPC Series (Smart, Compact, and Flex) and the XBTGTW Series target

machines come with one to four COM ports. All serial ports use 9-pin SUBD male

connectors and support RS-232C serial communication. The following table

illustrates the pin layout for these target machines.

COM1, COM2, COM3, OR COM4 (9-pin SUBD Plug)

RS-232C

Magelis XBTGK, XBTGC2000, and XBTGT2000 Series or higher

All XBTGK and XBTGT2000 Series and higher target machines have two COM

ports: COM1 and COM2. The XBTGC2000 Series has one COM port: COM1.

XBTGH2000 Series (Junction Box) has one COM port: COM1.

COM1 is a 9-pin SUBD male connector and COM2 is an RJ45 socket. The following

tables illustrate the pin layout for these target machines.

COM1 (9-pin SUBD Plug)This COM port can act as either an RS-232C or RS-422 interface.

When making your own connections, use shielded RJ45 connectors. The shielded

connector provides isolation against noise and provides a secure physical

connection in the RJ45 socket. Using an improper RJ45 plug could lead to loose

Cable Diagrams

Schneider Electric recommends using the following diagrammed connections.When creating your own cables, to identify which pins to connect on the targetmachine, see Target Machine Serial Interface.

Note:

Ensure that the equipment is properly grounded as indicated in the user manual

and follows all applicable country standards.

When signal lines overlap as shown below, it indicates a twisted pair.

Diagram 1 - DeviceNet

To connect the target machine and the PLC, use the recommended cables andaccessories.

DANGERELECTRIC SHOCK

Isolate local ground connection for each component of interconnected equipment.

There is a risk of electric shock when connecting a PLC cable to a target machine,

as the two may be at different electrical potentials, even if both are separately

connected to ground.Failure to follow these instructions can result in death or serious injury.


To reduce communication interference as a result of electromagnetic interference,use shielded twisted-pair cables. Connect the cable shields, then connect the

cable to a single-point ground on the HMI side.

Failure to follow these instructions can result in death, serious injury, or

equipment damage.

Note: The first and last stations on the network should be terminated with 121 ohm 1/4

Watt resistors.

Supported Device Addresses

Overview

The following tables list the device address ranges you can enter from the Device

Address keypad.

For actual device address ranges supported by the PLC, refer to the correspondingPLC manual.

I/O

I/O is process data that is exchanged between the DeviceNet Slave Unit (target

machine) and the DeviceNet master (PLC). This data is continuously updated andis available to the application.

*1 Read-modify-write. When you write to one of these bit addresses, the targetmachine reads the entire word address, sets the defined bit, then returns the new

value to the PLC. If the ladder program writes data to this word address during

the bit read/write process, the resulting data may be incorrect.

*2 Read-only.

*3 Range shown is the maximum range supported by the DeviceNet Slave (target

machine). Actual maximum depends on the input and output area allocated to

the slave (target machine) by the DeviceNet Master (PLC).

WARNINGUNINTENDED EQUIPMENT OPERATION

Design your system to avoid conflicting write processes between the target

machine and PLC program. Values on the PLC and target machine will be

incorrect if:

The target machine and PLC program attempt to simultaneously write to the

same register.

PLC programs or other devices write 16-bit word values to registers being

accessed in a bitwise manner.
