Control of production from serial port (BMS)
You can set the electronic control to use as a primary control signal value
from the serial port instead of the electrical terminals.
The value will be used according to the selection made on the parameter
“Installer / Regulation Type / Select Regulation” corresponding to the
variable non-volatile serial Intera 15.
If serial communication is interrupted (no data for the address of the
control for a set time), the production will stop and an alarm will sound
and the production will resume restoration of serial communication.
Operate as follows:
- Parameter “Installer / Supervisor / Supervisor Connect / Reg. from BMS
‘: default off , set to ON (or via serial non-volatile digital serial Variable 80:
default 0, set to 1)
- Variable volatile serial Full 53: Set a value between 0 and 1000:
Proportional: tenths of a percentage, Temper: tenths of ° C / ° F, humidity:
tenths of RH%.
- Variable Serial Digital 79: warning SERIAL OFFLINE
- Parameter “Installer / Supervisor / Supervisor Connect / Offl ine al. Delay
“(or via serial Variable nonvolatile serial Full 54): SERIAL OFFLINE alarm
detection time in seconds, default 60.
Stop production from serial port (BMS)
You can stop the output from the serial port.
In addition to the detention serial, there are also the following stops:
-on/off Terminal
-on/off By remote contact
If even a single fi rm is active production stops.
To stop the production serial follow these steps:
- Parameter “Installer / Supervisor / Supervisor Connect / Enable ON / OFF
from supervisor” : Set to Yes (or via serial non-volatile digital serial Variable
81: default 0, set to 1)
- Variable nonvolatile digital serial 8: ON / OFF serial, default off (0); set to
0 to stop, 1 for non-stop production.
Modbus® protocol
The protocol Modbus ® is available by selecting from the menu installer
mask supervisor.
Chapter 13.6 shows a list of variables and the corresponding addresses.
For multiple read/writes, the maximum number of “Register” or “Coil”
variables is 20.
The following functions are available:
MB_READ_COIL_STATUS 1: used to request the status (ON or OFF)
of a certain number of “Coil” variables (binary, 1 bit), starting from the
specifi ed address.
MB_READ_INPUT_STATUS 2: operationally identical to the above.
MB_READ_HOLDING_REG 3: used to request the value of a
consecutive block of “Register” variables (nu-meric, 16 bit).
MB_READ_INPUT_REG 4: operationally identical to the above.
MB_FORCE_SINGLE_COIL 5: used to set the status of an individual
“Coil” variable (binary, 1 bit) to ON or OFF (specifying the address of the
bit in question).
MB_PRESET_SINGLE_REG 6: used to set the value of an individual
“Register” variable (numeric, 16 bit).
MB_FORCE_MULTIPLE_COIL15: used to set the status of a consecutive
block of “Coil” variables (binary, 1 bit) (specifying the number of bits and
number of bytes).
MB_PRESET_MULTIPLE_REG16: used to set the value of a consecutive
block of “Register” variables (nume-ric, 16 bit).
Exceptions managed:
01 illegal function
02 illegal data address
Important: for the tLAN and pLAN connections in residential
household (IEC EN 55014-1) and residential (IEC EN 61000-6-3)
environments, use shielded cable (with shield connected to GND). This
warning also applies to the cables leaving the unit.
