ABB Comli
This comli plugin is used to access ABB's COMLI compatible control system through serial port.
Parameters
| Parameter | Description |
|---|---|
| Recv Timeout | The time of the system waits for a device to respond to a command. |
| Send Interval | The waiting time between sending each read/write command. Some serial devices may discard certain commands if they receive consecutive commands in a short period of time. |
| Send Retry | The number of retransmissions of the master request command when the slave returns with no response command. |
| Serial Port | The path to the serial device when using a serial connection, e.g., /dev/ttyS0 in Linux systems. |
| Stop Bits | Serial connection parameter. |
| Parity | Serial connection parameter. |
| Baud Rate | Serial connection parameter. |
| Data Size | Serial connection parameter. |

Address format
SLAVE!AREA.ADDRESS[.BIT][#ENDIAN][.LEN[H][L][D][E]]
SLAVE
Required, Slave is the slave address or site number.
AREA ADDRESS
| Area | Data Type | Register Size | Attribute | Address Range | Area Description | Note |
|---|---|---|---|---|---|---|
| 0 | bit | 1bit | Read/Write | 0 ~ 16383 | I/O-bits | |
| 1 | ALL | 16bit, 2byte | Read/Write | 0 ~ 3071 | Register | the type of bit read only |
.BIT
Optional, specify a specific bit in a register, as:
| Address | Data Type | Description |
|---|---|---|
| 1!1.100.0 | bit | Refers to station 1，Register area，address 100，bit 0. |
| 1!1.100.4 | bit | Refers to station 1，Register area，address 100，bit 4. |
| 2!1.200.15 | bit | Refers to station 2，Register area，address 200，bit 15. |
#ENDIAN
Optional, byte order, applicable to data types int16/uint16/int32/uint32/float/int64/uint64/double, see the table below for details.
| Symbol | Byte Order | Supported Data Types | Note |
|---|---|---|---|
| #B | 2,1 or 8,7,6,5,4,3,2,1 | int16/uint16/int64/uint64/double | |
| #L | 1,2 or 1,2,3,4,5,6,7,8 | int16/uint16/int64/uint64/double | Default byte order if not specified |
| #LL | 1,2,3,4 | int32/uint32/float | Default byte order if not specified |
| #LB | 2,1,4,3 | int32/uint32/float | |
| #BB | 3,4,1,2 | int32/uint32/float | |
| #BL | 4,3,2,1 | int32/uint32/float |
.LEN[H][L][D][E]
When the data type is STRING, .LEN is a required field, indicating the number of bytes the string occupies. Each register contains four storage methods: H, L, D, and E, as shown in the table below.
| Symbol | Description |
|---|---|
| H | One register stores two bytes, with the high byte first |
| L | One register stores two bytes, with the low byte first |
| D | One register stores one byte, and it is stored in the low byte |
| E | One register stores one byte, and it is stored in the high byte |
