HELP! How to read this kind of register - Tuwat47 - 04.10.2024

Hi everyone,

I've integrated a Caleffi Conteca device on my LM and everything works well. I'll share my .json just after I'll solve this problem.

I would like to  add the register in attached and have a different GA output for every kind of alarm. For example:

- bit0 - Errore on Flow Temperature - 0/5/0
- bit1 - Errore on return temperature - 0/5/1
- bit6 - Low Battery Alarm - 0/5/2

and go on for the other bit of alarm.

Can someone explain me how to do? 

Thanks in advance.

Hi Admin and thanks for your answer.

My LogicMachine knowledge is not so pro to let me know how go on with this issue. Can you halp me a little bit more?

Code:
{         "name": "Alarm Status - bit 0 - Error flow temperature",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask" : what can I use for reading bit0?         "value_custom": {"01": "OK", "1": "Alarm"}       }, {         "name": "Alarm Status - bit 1 - Error return temperature",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask" : what can I use for reading bit1?         "value_custom": {"01": "OK", "1": "Alarm"}       },

Please consider to help me.

Use this. I've also fixed incorrect value_custom (should be "0" instead of "01").
Code:
{   "name": "Alarm Status - bit 0 - Error flow temperature",   "bus_datatype": "bool",   "datatype": "uint16",   "type": "register",   "address": 119,   "value_bitmask": 0x01,   "value_custom": {"0": "OK", "1": "Alarm"} }, {   "name": "Alarm Status - bit 1 - Error return temperature",   "bus_datatype": "bool",   "datatype": "uint16",   "type": "register",   "address": 119,   "value_bitmask": 0x02,   "value_custom": {"0": "OK", "1": "Alarm"} },

Hi Admin I don't have my LM for testing the result, but what do you think if I use this kind of .json for reading every single bit?

Code:
{                               [       {         "name": "Alarm - bit 0 - Error flow temperature",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask": 0x1,         "value_custom": {"01": "OK", "1": "Alarm"}       },       {         "name": "Alarm - bit 1 - Error return temperature",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask": 0x2,         "value_custom": {"01": "OK", "1": "Alarm"}       },       {         "name": "Alarm - bit 6 - Low battery alarm",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask": 0x40,         "value_custom": {"01": "OK", "1": "Alarm"}       },       {         "name": "Alarm - bit 8 - Measurament unit mismatch on main counter",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask": 0x100,         "value_custom": {"01": "OK", "1": "Alarm"}       },       {         "name": "Alarm - bit 9 - Measurament unit mismatch on counter 1",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask": 0x200,         "value_custom": {"01": "OK", "1": "Alarm"}       },       {         "name": "Alarm - bit 10 - Measurament unit mismatch on counter 2",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask": 0x400,         "value_custom": {"01": "OK", "1": "Alarm"}       },       {         "name": "Alarm - bit 11 - Measurament unit mismatch on counter 3",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask": 0x800,         "value_custom": {"01": "OK", "1": "Alarm"}       },       {         "name": "Alarm - bit 12 - Measurament unit mismatch on counter 4",         "bus_datatype": "bool",         "datatype": "uint16",         "type": "register",         "address": 119,         "value_bitmask": 0x1000,         "value_custom": {"01": "OK", "1": "Alarm"}       },                                        ] }

If it will work I'll post my .json for Caleffi Conteca.

Ok, perfect. I will try as soon as possible. Thanks in advance for your help Admin.

Fixed profile attached.

RE: HELP! How to read this kind of register - nhemtman - 11.03.2025

Hi,

Could any of you help me? I need help with registers 138-139. It's a BITMAP32 register, where 0-15 are read as LSW and 16-31 are read as MSW (see example below), how are these parameterized in the modbus profile? I also attached the manual and the modbus profile I made. Thanks!


 
0x00100071 > Byte 1  ( 0x00 ), Byte 2 (0x71), Byte 3 (0x00), Byte 4 (0x10)
MSB, LSW                   


MSB: Most significant byte first
LSW: Least significant word first
 
In That example the following bits are set(counting starting at 0):
  • 0 sensor error
  • 5 pump 1 alarm
  • 6 pump 2 alarm
  • 7 pump 3 alarm
  • 20 net supply

Use profiler app: https://forum.logicmachine.net/showthread.php?tid=5911

Use Value bitmask option. Click the calculator icon to select the required bits. Set Modbus data type to uint32 and Object data type to 1 bit.
