ETH_MOD_MAST

The ETH_MOD_MAST Function Block implements the open MODBUS on TCP/IP client functionality for the ETHERNET Communication Module specified at input SLOT. Depending on the configuration of the Communication Module, several ETH_MOD_MAST Function Blocks can be used in parallel. Prior to the use of ETH_MOD_MAST the Communication Module has to be configured.

With each FALSE > TRUE edge at input EN, the Function Block ETH_MOD_MAST reads the values at the inputs, generates a telegram according to the inputs and then sends this telegram to the slave.

Note

Only a single instance per slave can be used with this Function Block.
