Modbus issues being interogated via windows XP home
Modbus issues being interogated via windows XP home
(OP)
Good morning. I have been trying to talk to a ABB acs 800 with a modbus card (reta 01 ) using a laptop with windows xp home edition as its operating system. I can with this lap top have full connectivity to our works intranet and also connect fully to the internet. I can also ping our servers . However when I connect the cable to the modbus card on the drive the icons in network connections tells me the cable is unplugged. I have tried different cables with the same result. I have also connected the card to a laptop with XP professional as its operating system and this connects immediatly. Is this a XP home edition problem , And has anyone experienced this before

Right click the wired ethernet port icon:
click on status to bring up the status screen

If the port status is not 'connected', try "repair"

Modbus TCP typically uses port 502.
Is port 502 blocked by Windows firewall?
Do you need to specfiy an exception ?
