Instructions ECL Comfort 210 / 310, communication description
7.1.1.2 Read parameters (0x04)
This function is used to read the value of an ECL Comfort
parameter number. Values are always returned as integer
values and must be scaled according to the parameter
definition.
Requesting a quantity of more than 123 parameters gives an
error response. Requesting non-existing parameter number(s)
will give an error response.
Request
Function code 1 byte 0x04
Start PNU 2 bytes 0x0001 – 0xffff
Quantity N of PNU 2 bytes 0x0001 – 0x007B
Response
Function code 1 byte 0x04
Byte count 1 byte 2 - 246
PNU data value 2 bytes 0x0000 – 0xffff
Error
Function code 1 byte 0x84
Error code 2 bytes 1, 2, 3 or 4
The request/response is Modbus compliant reading a sequence of parameters (Read input register).
7.1.1.3 Write parameter number (0x06)
This function is used to write a new setting value to an ECL
Comfort parameter number. Values must be written as
integer values and
must be scaled according to the parameter
definition.
Attempts to write a value outside the valid range will give an
error response. The minimum and maximum values must be
obtained from the instructions for ECL Comport controller.
Request
Function code 1 byte 0x06
Write PNU 2 bytes 0x0001 – 0xffff
New PNU value 2 bytes 0x0000 – 0xffff
Response
Function code 1 byte 0x06
Write PNU 2 bytes 0x0001 – 0xffff
New PNU value 2 bytes 0x0000 – 0xffff
Error
Function code 1 byte 0x86
Error code 2 bytes 1, 2, 3 or 4
The request/response is Modbus compliant when writing a parameter (Write single register).
