• Modbus communications can be used on port B.

The corresponding parameters are those for

variable types C4/84, C5/85, and D0/90 to D6/96.

• Software version 2 of the G3ZA Multi-channel Power

Controller can be used.

Note: 1. When more than one G3ZA Multi-channel

Power Controller is connected, version 1 and

version 2 can be mixed. (Up to 8 G3ZA Multi-

channel Power Controllers can be

connected.)

2. Software version 2 of G3ZA Multi-channel

Power Controller can also be used with EJ1

version1.0.

• Autotuning is provided for heating/cooling control.

• Self-tuning has been added.

• A switch can be used to display the output status on

the operation indicators during operation.

• Modbus communications can be used to read and

write all parameters, and to execute any of the

operation commands.

• A switch setting can be changed to use Modbus

communications on port B.

• A switch setting can be used to set the baud rate of

port B.

• A C0/80 status has been added to the variable types.

• Up to eight G3PW Power Controllers can be

connected to one Basic Unit.

Note: 1. The G3PW can be connected to EJ1 V1.1.

2. The G3PW and G3ZA cannot be used

together.

Advanced Unit

(EJ1N-HFU

@-NFL@)

• Programless communications can be used with 1: N

connections.

• The maximum number of parameters that can be

specified for programless upload/download settings

has been increased from 300 to 600 each.

• Connection is now possible to MELSEC-QnA/An/

AnS/FX3uc-series PLCs.

• A new setting read operation has been added to

programless communications: Setting Read 2.

• The speed of programless communications has

been increased.

• Either "continue" or "stop" can be selected for when

errors occur in programless communications.

• Bit specification operation commands have been

added to the parameters that can be specified for

programless download settings. This simplifies the

program when operation commands are executed.

• The G3ZA or G3PW Monitor parameter has been

added to the parameters that can be specified for

programless upload settings. Up to four G3ZA Multi-

channel Power Controllers or up to four G3PW

Power Controllers can be connected to one Basic

Unit.

• The maximum number of parameters that can be

specified for programless upload/download setting

has been increased from 600 to 1200 each.

• The maximum number of Basic Units that an HFU

with Programless Communications can control has

been increased from 16 to 32 Units.

• Communications unit numbers 32 to 39 can be used

in the HFU via programless communications.

This allows the communications unit numbers of

Basic Units connected to an HFU to be numbered

sequentially, making it easy to copy HFU and Basic

Unit settings to other HFUs and Basic Units.
