Modbus Address for the Base Control Module's RS-485 port. The address is loaded at
startup. A power cycle is required for a change of address to take effect.
Selects the Modbus Baud Rate for the Base Control Module's RS-485 Modbus port. A
power cycle is required for a change in baud rate to take effect.
0 = 19200
1 = 9600
2 = 38400
3 = 57600
4 = 115200
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)
Selects the Modbus Parity and Stop Bits for the Base Control Module's Modbus port.
A power cycle is required for a 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 bits
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.
The Active IP Address being used on the Network
The Active Subnet Mask IP Address being used on the Network
The Active Default Gateway IP Address being used on the Network
The IP address used in the NV address select configuration. The DIP switch settings
on the Base Control Module determine if a static IP address of 192.168.1.X, where X
= the value on the DIP switch settings, is used, or if DHCP is used or if the IP address
stored at this parameter is used. To use this IP address, enter an IP address for this
parameter, power down the C445, set the DIP switches for the NVMEM, and when
the unit is powered again, the C445 Ethernet module will be using this address.
The IP subnet mask used in the NV address select configuration. If the DIP switches
on the Base Control Module are set for NVMEM, this IP subnet mask will take effect
following a power cycle.
The IP default gateway used in the NV address select configuration.
Allows setting of the method used to set an IP address.
0 = Restore (192.168.1.254).
1 = DHCP.
2 = Full address from NV Memory.
3 = Upper three octets from NV and lower octet selected by the DIP switch setting.
Unique MAC address assigned to this device (the Ethernet card)
Address Conflict Detection enable. ACD provides protection from duplicate IP
addresses on the network.
0 = Disable ACD
1 = Enable ACD
