Hi guys, I continue without undertanding COM_MOD_MAST settings, I checked some ABB examples but I still not understand how set the pins FCT, ADDR, NB and DATA. My dude is the FCT is of master or slave code function, because to master is FCT=16(w) but in datasheet slave the function code is 3, wich use to configure el FB master,? the ADDR is the addres of register in the slave but wich is the format, some examples use Arrays to configure, the pin NB is the number of bit, byte, word etc, but is the NB only of data or all bits of modbus (address slave, function code, data, praity and stop),.? and DATA pin is data some examples use ADR. The slave is a variator, no ACS, I think configure the code registers in an array after sent the data using one com_mod_mast block per each parameter in the slave is correct,.?? thanks guys.
