Errors
If a code other than the indicated read or write code is used, the response received is:
Nº slave – Code OR 80Hex – Code error (1) – CRC16 (2 bytes)
If an attempt is made to read or write access to a record with a nonexistent address, the response received is:
Nº slave – Code OR 80Hex – Code error (2) – CRC16 (2 bytes)
If you try to write to a read-only register or try to write an illegal value to a register, the response you receive is:
Nº slave – Code OR 80Hex – Code error (3) – CRC16 (2 bytes)
Registers map
The unused bits of the following registers are 0.
Note: In some communication programs the first word address is configured as 400001, so that register 0 of the probe regulato r corresponds to
the word address 400001. In summary,
the word address to which each register of the probe regulator corresponds It is calculated by adding 1 to the record number of the record map
described below.
ID Register of the regulator
Register 0: 151 [only lecture].
- The sensor regulator always responds 151 as a 16-bit binary sentinel point.
Read/write registers.
Register 1: communication directors [lecture/write].
- The value that is sent is the address value (1 to 240) in 16-bit binary.
Default value: 1 [1].
If the controller is connected to a serial communications network, it is not possible to configure any equipment on the
network at address 245, since the controller also responds to that address.
BROADCAST ADDRESS: Address 250 (the controller receives the communication but does not respond). All write registers are broadcast.
Register 2: Operating status on/off (manual mode) [read/write].
0: Off. 1: On.
Value by default: 0 [0ff].
Off: Relé on/off desactivated (open contact).
On: Relé on/off activate (closed contact).
=240 (0xF0): Values by default.
=247 (0xF7): Calibratio sensor CO2. IMPORTANT: Consult calibration proces.
=255 (0xFF): Reset.
Register 3: Consignment CO2 (output "Regulation CO2") [read/write].
- The value sent is the consignment (400ppm a 1400ppm) in binary 16 bits.
Value by default: 800 [800ppm]. [Register 4 ≤ Register 3 ≤ Register 5]
The consignment corresponds also with the consignment alarma in case it's enabled.
Register 4: Minimum consignment CO2 (outputs "Regulation CO2") [read/write].-
The value sent is the minimum consignment (400ppm a 1400ppm) in binary 16 bits.
Value by default: 400 [400ppm]. [Register 4 ≤ Register 5]
Register 5: Maximum consignment CO2 (outputs "Regulation CO2") [read/write].
- The value sent is the maximum consignment (400ppm a 1400ppm) in binary 16 bits.
Value by default: 1400 [1400ppm]. [Register 4 ≤ Register 5]
Register 6: Hysteresis (output "Regulation CO2" On/off) [read/write].
- The value sent is the Hysteresis (50ppm a 400ppm) in binary de 16 bits.
Valore per difetto: 200 [200ppm].
Register 7: Banda proportional (output "Regulation CO2" proportional) [read/write].
The value that is sent is the value of the proportional band (100ppm a 600ppm) in binary 16 bits.
Value by default: 400 [400ppm].
