Hello,

I want to read data with CITECT from a IP Master (ISYGLT) with a MODBUS!!

The problem is that the IP Master does not respond.

Does somebody know what I do wrong??

The I/O server, Boards, Ports, I/O devices and variable tags are made

Server
Servername = IOServer

Board
Servername = IOServer
BoardName = TCPIPx
Boardtype = TCPIP
board adres = 0
The other fields are blank

Port
Servername = IOServer
Port name = TCPIP1
BoardName called = TCPIPx
Specila opt. = -I192.168.0.225 -P0 -T
The other fields are blank

I/O device
Servername = IOServer
IOdevice name = ISYGLT
Protocol = MODNET
Portname called = TCPIP1
The other fields are blank.

Variable tags
Variable tags name = MODBUS_40001
IOdevice name = ISYGLT
Data type = int
Adress = 40001
The other fields are blank.

IP-Master
Protocol (MOBUS/TCP(P502) and Port 502

connection = 4.MODBUS Holding Register (Byte/Word)von MODBUS lesbar- und schreibbar

MODBUS Holding Register (Byte/Word)  von MODBUS lesbar- und schreibbar
Nur Bytes und Words

MODBUS Start-Register: 1
MODBUS Länge (Anzahl Bytes): 4
MODBUS Länge (Anzahl Words): 4
ISYGLT Merker-Bank : NA
ISYGLT Start-Merkernummer: 1

MODBUS is working with Programmer designer and ModScan32.

Kind regards,
