Communication between Schneider HMIGTO2300 and TWDLCAA10DRF

[tewatute]

Hello,

i need some help!!

i connected both via rs-485 by lan cable.

HMI PLC

RJ-45 Mini Din 8 pin

pin4 A <---> pin1 A

pin5 B <---> pin2 B

pin8 SG <---> pin7 0V

PLC : I config in Twidosuite(Descrobe) to 19200 8 E 1 tried other baud rate too.

HMI : I config in IO Manager --> ModbusRTU01[Com2] to 19200 8 E 1 and ModbusEquipment1 to address 1(PLC)

but when i power on i get msg on HMI display "No reply from PLC within Timeout period. (ModbusEquipment01)"

i need config more? i missed something?

please help!!! or give some instruction.

Thank you.

tewatute,

Herewith the configuration of Both..

PLC TWDLCAA10DRF

1. Using Twido Suite, at the Describe Toolbar, put by drag and drop PLC (Base->Compact->TWDLCAA10DRF) and HMI (Network Elements->Modbus Elements->Magelis)

2. Connected point to point PLC and Network Element
3. Configuration setting:
a.
Network Elements
Name = any
Type = Modbus
Address = Master
b.
Network
Type = No Change
Name = any
Baudrate = 19200
Data Bits = 8 (RTU)
Parity = none
Stop Bit = 1
Timeout = 10 x 100ms
Time between frames (ms) = 10 ms

c.
Twido PLC Port 1:
Type = No Change
Address = 1 (Should be same as the HMI)

HMI Vijeo Designer

IO Manager, selected:
a.
Manufacturer = Schneider Electric Industries SAS
Driver = Modbus (RTU)
COM Port = COM1
Serial Interface = no change
Flow Control = no change
Transmission Speed = 19200
Parity Bit = None
Stop Bit = 1

b.
Equipment Configuration = Modbus Equipment
Slave Equipment Address = 1
Comm. Optimization = Custom, 120 bytes
IEC61131 Syntax = "Check"
Addressing Mode = 0-based (Default)
Variables = Double Word word order (Low word first), ASCII Display byte order (Low byte first)
