Communication Parameters Configuration
COUNTER_OF_RECEIVED_MESSAGES (30004)
The 32-bit register with the number of valid Modbus messages received by the room panel from the time of the last power-up. The value is reset after power cycle or after changing of transmission parameters (speed, stop bits, parity, etc.).
COUNTER_OF ERROR_MESSAGES (30006)
The 32-bit register with the number of error Modbus messages received by the room panel from the time of the last power-up. The value is reset after power cycle or after changing of transmission parameters (speed, stop bits, parity, etc.).
COUNTER_OF_SENT_MESSAGES (30008)
The 32-bit register with the number of Modbus messages sent by the room panel from the time of the last power-up. The value is reset after power cycle or after changing transmission of parameters (speed, stop bits, parity, etc.).
BAUD_RATE (40017)
The actual baud rate in bps divided by 10. By default: 11520 (115200 bps).
Value | Baud Rate |
|---|---|
480 | 4800 |
960 | 9600 |
1920 | 19200 |
3840 | 38400 |
5760 | 57600 |
11520 | 115200(def) |
STOP_BITS (40018)
The number of stop bits is determined on the basis of this register in accordance with the following table:
Value | No. of Stop Bits |
|---|---|
1 | 1(default) |
2 | 2 |
PARITY_BIT (40020)
Each byte of data being transferred may have additional protection of a parity bit added before stop bit (bits).
The method of calculating parity bit determines the below table:
Register Value | Type of Parity Bit |
|---|---|
0 | None(def) |
1 | Odd (number of all ones in a byte is odd) |
2 | Even (number of all ones in a byte is even) |
RESPONSE_DELAY_TIME (40021)
The value of this 16-bit register determines the number of milliseconds to wait before the unit answers the question. This time is used to extend the interval between the question and the answer.
The default value of 0 means no delay (the answer is sent once during the 3.5 character required by the protocol Modbus RTU).
PANEL_ADDRESS (40023)
This register contains information about the Modbus address of the room panel.
The default address is 1.
PROTOCOL (40024)
The register is responsible for the protocol selection. The protocol is determined according to the register value as shown in the following table:
Value | Action |
|---|---|
0 | Modbus RTU(def) |
1 | Modbus ASCII |
2 | BACnet MS/TP |
