Dear All,
Is it possible to configure AC500 PLC to act as ModbusTCP Slave+Client at the same time?

Hi，
It is possible. If the parameter `no of parallel server connections` is set greater than 0 ，then the AC500 PLC can also function as a modbus server.
The parameter is located in the Modbus Tcp-Ip protocol settings page (protocol appended to any ethernet port i.e. onboard or CM597).
The AC500 PLC can allow a max of 12 simultaneous modbus client connections. The value set in the parameter determines the maximum allowed simultaneous modbus client connections to the PLC.
In addition to the above，ETH_MOD_MAST blocks may be used to communicate with other modbus servers in parallel.
Note: Higher the parameter value more no of sockets will be reserved.
