Modbus timeout and Write Problem

[savaskorkmaz]

Hi ,
We have modbus device that we can read and write each indivual register via modbus poll. Also we can read all these register if we create a profile file includes only 1 register. But if we make a profile includes 5 register instead of 1 register , we have timeout problem and modbus communication turns red. 

We tried 2 different profile files.

Profile 1 and test results :
With this profile file , at the beginning we read 2552, 2554 , 2566 . After 3 seconds, timeout error, modbus turns red and no read anymore.

  "manufacturer": "Gree Klima",
  "description": "Gree Klima Modbus",
  "mapping": [
{"address": 2552, "name": "Klima On-Off-99", "datatype": "uint16", "bus_datatype": "uint8", "type": "register",  "writable": true},
{"address": 2553, "name": "Operation Mode-99", "datatype": "uint16", "bus_datatype": "uint8", "type": "register",  "writable": true},
{"address": 2554, "name": "Setpoint-99", "datatype": "uint16", "bus_datatype": "uint16", "type": "register",  "writable": true, "value_multiplier": 0.1},
{"address": 2555, "name": "Fan Speed-99", "datatype": "uint16", "bus_datatype": "uint8", "type": "register",  "writable": true},
{"address": 2566, "name": "IAT-99", "datatype": "uint16", "bus_datatype": "uint16", "type": "register", "value_multiplier": 0.1}
  ]


Profile 2 and test results :
With this profile file , at the beginning we can read all registers . After 3 seconds, timeout error, modbus turns red and no read anymore.

{ "address": 2552, "read_count":4, "read_offset":0, "read_delay":0.1, "name": "Klima On-Off-99", "datatype": "uint16", "bus_datatype": "uint8", "type": "register", "writable": true },
{ "address": 2552, "read_count":4, "read_offset":1, "read_delay":0.1, "name": "Operation Mode-99", "datatype": "uint16", "bus_datatype": "uint8", "type": "register", "writable": true },
{ "address": 2552, "read_count":4, "read_offset":2, "read_delay":0.1, "name": "Setpoint-99", "datatype": "uint16", "bus_datatype": "uint16", "type": "register", "writable": true },
{ "address": 2552, "read_count":4, "read_offset":3, "read_delay":0.1, "name": "Fan Speed-99", "datatype": "uint16", "bus_datatype": "uint8", "type": "register", "writable": true },
{ "address": 2566, "name": "IAT-99", "datatype": "uint16", "bus_datatype": "uint16", "type": "register", "value_multiplier": 0.1}
  ]


Problem 2 : 

We cannot write any of this register. If we put only 1 register ( For example set point ) in to profile, there is no timeout problem and there is no read problem. But we cannot write the value to modbus.

Need advices.
