MODBUS WRITE FUNCTION AND WRITING TO
GATEWAY
In order to relay data from a third-party Modbus Master device to a point
or output in an OleumTech network, a Modbus Write function must be
created in primary Gateway’s Modbus table. Once the function is created,
then this point can be mapped to an output or shared with another device
within the network.

same Modbus holding register(s). Last written command supersedes all
other commands.
Gateway must be set up as a Slave to allow this function.
