Modbus Communication Portfolio

GS 34P02P21-01E

 GENERAL

This describes Modbus Communication Portfolio for STARDOM. Modbus Communication Portfolio easily allows FCN/ FCJ to be Modbus-capable through serial or Ethernet communications.

 FUNCTION SPECIFICATIONS  Modbus Communication Portfolio Modbus Communication Portfolio is a POU that enables FCN/FCJ autonomous controllers and Modbus communications protocol support devices to easily acquire and set data from and to each other through serial or Ethernet communications. The following communication modes and types are supported: Communication type

Communication mode ASCII mode RTU mode Modbus / TCP

Serial Ethernet

Communication function Master / Slave Master / Slave Client / Server

 Connection with CENTUM CS 3000 using Modbus Communications FCN/FCJ connects with CENTUM CS 3000 Field Control Station (hereinafter referred to as FCS) using Modbus Communication Portfolio. The dual redundant connection is enabled. Communication type of FCS or FCN/FCJ Communication type (Communication mode) Serial (RTU mode) Ethernet (Modbus/TCP)

Communication function FCS FCN/FCJ Master Slave Client Server

FCS requires the Communication Package below.

Communication Package of FCS Commucnication type (Communication mode) Serial (RTU mode) Ethernet (Modbus/TCP) *1: *2: *3:

Communication Package of FCS Model LFS9153 “Modbus Communication Package (for ALR111, ALR121)” (*1) Model LFS2453 “Modbus Communication Package (for ALE111)” (*2) (*3)

For details, see GS 33Q03L40-33E. For details, see GS 33Q03L40-34E. To connect FCS with FCN that has duplexed CPU, CENTUM CS 3000 R3.08 or later is necessary.

The diagnostic code when a command is received is 0 (zero). Only basic device ID numbers, such as vender names, product codes, and revision numbers, are applicable. These function codes support broadcast communications. If the station parameter for each POU is set to 0 (zero), broadcast communications are executed. Broadcast communications are not supported in Ethernet. These function can be used only when Modbus communication protocol support devices is supporting the communication for 32 bit access.

Module

If the CPU module (Model: NFCP100) is duplexed, the serial port of the module cannot be used. The modules allow the CPU module to be duplexed. Up to eight RS-232-C and RS-422/RS-485 communication modules can be mounted on each FCN (Except FCN-RTU). Total number of the following POUs shall be up to 32 in FCN/FCJ since each POU occupies one channel. - SD_FCXPE_OPEN (Ethernet Communication Function Block) - SD_CMELSECE_OPEN and SD_CMELSECE_3E_OPEN (POU of MELSEC Communication Portfolio) - SD_CFAM3E_OPEN (POU of FA-M3 Communication Portfolio) - SD_CMDBSE_BC_OPEN (POU of Modbus Communication Portfolio) Up to 31 devices per serial port can be connected. FCN-RTU (Model: NFCP050) does not support RS-232-C and RS-422/RS-485 communication module.
