Modbus multiple registers - Too many data - buuuudzik - 07.03.2018 I've found that there is so limit when I try read the multiple registers. When the number is more than 125 then instead of data there is the info that there is too many data. Is there a possibility to take more data by one request? Sometimes useful addresses are very far from them and this is not only about of amount addresses but much more about that I want take all data by one request. RE: Modbus multiple registers - Too many data - admin - 07.03.2018 It's limited by ModBus standard: max_read_bits = 2000 max_write_bits = 1968 max_read_registers = 125 max_write_registers = 123 RE: Modbus multiple registers - Too many data - buuuudzik - 07.03.2018 Thanks for answer |
