trying to establish Modbus TCP communication between wago 750-8212(PFC200) and Modscan32 (modbus client software intalled in PC).
following error I am getting
IoDrvEthernet: [br0] successfully opened with IP: [192.168.58.126] and Subnetmask: [255.255.255.0]
IoDrvEthernet: [eth0] is disabled for changing communication settings!
IoDrvEthernet: Setting IP Address and Subnetmask returned with Error Code 39.

you need either to remove the 'adjust ip setting' ( see screendump)
or allow the runtime to change the IP.
How to do this?

In /etc/CODESYSControl_User.cfg you need to add

[SysSocket]
Adapter.0.Name="br0"
Adapter.0.EnableSetIpAndMask=1
