This protocol supports data reading/writing from the controllers of ALYA lubricant reservoirs.
Since July 2015, this protocol supports a group of I/O tags for data reading/writing from/to the Manex production lines - see Table 4.
From January 2023, a TCP/IP-TCP line is supported for reading data from the Big-bag scale controlled by 3BR electronics.

- Communication protocol: ALYA Lubrikacie.
- The station address is an the address of the control station for the communication over the RS485 bus. The address is a one-byte value.
Note: commonly used station addresses (A, B, C...) must be configured as their ASCII codes, i.e. 65, 66, 67 ...
...
If a keyword with an invalid value in the initialization string is used, the corresponding default value according to the table 1 will be used.

I/O tag address is an abbreviation of the mnemonic name of the I/O object. The list of objects is shown in the table below (not every device supports all objects):
Table 2
| Address | Meaning | Value type | Read/Write |
|---|---|---|---|
| AV | Actual (current) weight [kg] | Ai | R |
| BV | Brutto weight [kg] | Ai | R |
| NV | Netto weight [kg] | Ai | R |
| CV | Total weight [kg] | Ai | R |
| EV | Error Current weight [kg] | Ai | R |
| HI | Emergency minimum [kg] | Ai, Ao | R/W |
| HA | Emergency maximum [kg] | Ai, Ao | R/W |
| PN | Operating minimum [kg] | Ai, Ao | R/W |
| PX | Operating maximum [kg] | Ai, Ao | R/W |
| SP | Filling status (TRUE - filling, FALSE - draining) | Di | R |
| EN | Error number - see Table 3 | Ai | R |
| WS | Write to serial EEPROM (all changes of Ao must be written to EEPROM - if not, they will be lost during the next reset) | Do | W |
| RT | Reset (it causes the reset of the control station) | Do | W |

| RX | Canceling of a roving. After an operator puts down the roving from the scale, the application will write the number of the scale (1 or 2) into the I/O tag. | Co | Write | ||||||
| The number of spools on the lines. The I/O tag is in the format "C1;C2;C3; … Cn;", where Ci represents an integral number that indicates the number of spools on the line i. Example: "626;42;0;78;562;489;28;55;" | TxtI | Read | ||||||
| NC | Reset the counters of spools on the lines. Write any valid value, to reset the counters. The control unit will send a message in the format "C1;C2;C3; … Cn;", where Ci represents an integer number that indicates the number of spools which that were included on line i since since the most recent information on the number of spools was sent (see PC). This message will be set as a new value of the I/O tag with the NC address. | TxtO | Write |
