Modbus Address
UINT8 RW NV
Default: 1
Range: 1 to 247
Config CRC
Admin Lock
USB Lock
Backup Mem
Modbus Address for the Base Control Module's RS-485 port. The address
is loaded at startup. A power cycle is required for change in address to
take effect.
6001
Modbus Baud Rate
UINT8 RW NV
Default: 0
Enum
Config CRC
Admin Lock
USB Lock
Backup Mem
Selects the Modbus Baud Rate for the Base Control Module's RS-485
Modbus port. A power cycle is required for change in baud rate to take
effect. 0 = 19200 baud, 1 = 9600 baud, 2 = 38400 baud, 3 = 57600 baud, 4 =
115200 baud.
6002
Modbus Parity and Stop
Bits
UINT8 RW NV
Default: 0
Enum
Config CRC
Admin Lock
USB Lock
Backup Mem
Selects the Modbus Parity and Stop Bits for the Base Control Module's
Modbus port. A power cycle is required for change to take effect. Note:
No Parity, 1 stop bit is not valid when in MODBUS_ASCII_TX_MODE
mode. 0 = Even Parity - 1 stop bit, 1 = Odd Parity - 1 stop bit, 2 = No Parity -
2 stop bits, 3 = Even Parity - 2 stop bits, 4 = Odd Parity - 2 stop bits, 5 = No
Parity - 1 stop bit.
6003
Modbus Port TX More
UINT8 RW NV
Default: 0
Enum
Config CRC
Admin Lock
USB Lock
Backup Mem
Selects the RTU/ASCII Modbus Mode for the Base Control Module's
Modbus port. 0 = RTU Tx Mode (8 Data Bits), 1 = ASCII Tx Mode (7 Data
Bits).
6004
Modbus Timeout
UINT16 RW NV
Default: 2000
Units: ms
Config CRC
Admin Lock
USB Lock
Backup Mem
The time before Modbus communications are considered lost. Every valid
message received will reset this timer. The timeout is in milliseconds.
When this timer expires, communication loss behavior will be triggered. A
value of zero (0) will disable the communication timeout.
6005
Base Control Module USB
Modbus Timeout
UINT16 RW NV
Default: 10000
Config CRC
Admin Lock
USB Lock
Backup Mem
The time before Modbus communications are considered lost. Every valid
message received will reset this timer. The timeout is in milliseconds.
When this timer expires, communication loss behavior will be triggered.
A value of zero (0) will disable the communication timeout.
