HRR Series 1.1 Communication mode and operation method
1-1
Chapter 1 Read before using
The communication of this device consists of contact input/output
communication and serial communication.
The serial communication protocol is a MODBUS communication.
Depending on the customer’s specification, communication can be
changed to contact input/output communication or serial
communication.
Table 1-1 Communication method
Contact input/output communication.
This product is equipped with a terminal which
runs/stops the product by remote control and a terminal which
can pick up alarm signals. The terminals can be changed
depending on the customer’s application.
Serial
communication
MODBUS standard
protocol
Serial communication (RS-485/RS232C) enables remote
control of run/start of the product, temperature setting, and
details of product condition and alarm condition can be obtained.
●If using contact input/output communication, refer to
chapter 2.
●If using serial communication MODBUS, refer to chapter
3.
1.1 Communication mode and operation method
LOCAL, DIO and SERIAL are available as the communication modes.
Table 1.1-1 explains the communication modes. The default setting is
LOCAL.
The operation method depends on the communication mode. Table
1.1-2 shows how the communication mode and method of operation
are related.
