  • Page 6: Rs-485 (Option)

    1． Introduction 1.1 About communication protocols This device has Modbus protocols. The Modbus protocols are communication protocols developed by Modicon Inc. (AEG Schneider Automation International S.A.S) for PLC, which are described in the document of protocol specifications (PI-MBUS-300 Rev.J). For the Modbus protocol specifications, see the document. This document contains the Modbus protocols' function codes and data content, which can be mainly used for this device.

    1.5 Modbus RTU protocol Items Specifications Transfer mode Communication speed 9600,19200,38400 bit/sec Parity None/Even/Odd Data length 8 bits Stop bit 1 bit/2 bits Slave address 1 to 247 ("0" must not be set) Interface RS-485 1.6 Modbus TCP protocol The communication through Ethernet is available. The protocol is Modbus TCP. 1.7 Addition of new items and map version Due to the version upgrade of the main unit, the content of the Modbus map may be changed.
  • Page 8 1.8 Types of communication connection structures The communication functions of this device allow communications with various devices. 1) Ethernet connection Connect with this device via Ethernet. Real time monitoring for the measurement values (*1), acquisition of the measured files (*2), Web access, clock synchronization or other operations using the attached software are supported.
  • Page 9 (*) Version 1.60 or later 2) RS-485 connection (Slave) Connect with this device via RS-485. Through the connection with this device from devices such as PLC or PC, measurement value acquisition, starting of recording, or other operations can be carried out. In this case, only one master device can be used. Up to 48 units of this device can be connected as slave devices.
  • Page 10 3) RS-485 connection (Master: remote AI) (Version 1.50 or later) Use RS-485 to connect the separately-sold "ZE7400A remote AI unit" or this device as a slave. With one unit of this device as a master, up to six units of ZE7400A or this device can be connected under it.
  • Page 11 4) RS-485 connection (Master: general-purpose connection) (Version 1.60 or later) With RS-485, data can be obtained and recorded from the ModbusRTU-supported general-purpose devices. With this device as the master, a maximum of 12 supported devices can be connected under it. The data to be obtained are specified individually on this device side. The data obtained can be assigned to the calculating channels of the main unit.
