Do you want to run Modbus-TCP with Classicladder?

Have you found the ClassicLadder documentation?
TCP/IP setup is mentioned in Section 9.2:
linuxcnc.org/docs/devel/html/ladder/classic-ladder.html#_modbus
[list]
[*]If no port name for serial is set, TCP/IP mode will be used…
[*]The slave address is the slave address (Modbus/RTU) or the IP address.
[*]The IP address can be followed per the port number to use (xx.xx.xx.xx:pppp) else the port 9502 will be used per default.
[/list]

Thank you, I read the documentation and browsed the forum before I posted my request.
Communication with the servomotor works using: mb2hal, qmodbus or by checking ping.
However, I cannot communicate using classicladder TCP.
My attempts:
in the config.hal :
loadrt classicladder_rt numPhysInputs=15 numPhysOutputs=15 numS32in=10 numS32out=10 numFloatIn=10 numFloatOut=10

addf classicladder.0.refresh servo-thread

loadusr -W classicladder --modmaster --modbus_port = 192.168.33.1: 502 custom.clp
#loadusr -W classicladder --modmaster custom.clp
#loadusr -W classicladder --modmaster custom.clp
#loadusr -W classicladder --modbus_port = 192.168.33.1: 502 custom.clp

or trying to configure a connection in file.clp:
MODBUS_MASTER_SERIAL_PORT=192.168.33.1:502
#MODBUS_MASTER_TCP_PORT = 192.168.33.1: 502
I used wireshark and debug to see changes.

Despite many attempts, so far without success
Works on the latest version of LCNC 2.83
Thank you for your interest in the topic.

... "Classic Ladder has a Modbus/TCP server integrated. Default port is 9502. (the previous standard 502 requires that the application must be launched with root privileges)."
Wireshark detect nothing.
IS it posible that need more privileges chmod 777 ?

I don't really know. Are you getting any information (errors) in the terminal?

Also if you use the default port 9502 do you see anything on wireshark at all?

edit:
Can you post your clp file?

Just to throw it in here, only in case you haven't heard of it before.
There is a component called MB2HAL, which also allows you to connect to Modbus-TCP devices.
linuxcnc.org/docs/2.9/html/drivers/mb2hal.html
If you are using Classicladder only for Modbus you can consider using this. Or to test the connection to ensure the hardware is connected properly.
