2002
ELC IO Modbus Address
UINT8 RW NV
Default: 1
Range: 1 to 247
Config CRC
Admin Lock
USB Lock
Backup Mem
Modbus Address for the communication link between Base Control
Module's RS-485 port and the ELC Modbus IO. The address is loaded at
startup. A power cycle is required for change in address to take effect.
ELC IO Modbus Address

External IO Modbus
Baud Rate
UINT8 RW NV
Default: 4
Enum
Config CRC
Admin Lock
USB Lock
Backup Mem
External IO Modbus Baud Rate. 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.
2004
External IO Modbus Parity and
Stop Bits
UINT8 RW NV
Default: 0
Enum
Config CRC
Admin Lock
USB Lock
Backup Mem
External IO Modbus Parity and Stop Bits. Selects the Modbus Parity and
Stop Bits for the Base Control Module - ELC IO link. 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.
