Ethernet command flags provide a way to configure the Ethernet module, when installed.
Some commands are specific to the Nanoline and others allow control from a remote device
via the Ethernet connection.
– Ethernet flags represent the bits of Modbus holding registers 0x0101 (Command
register) and 0x0102 (Status register).
– Flags 136-151 are commands (see Table B-5) and may be turned on or off.
– Flags 152-167 are status flags (see Table B-6) and are read only.
If the NLC-COM-GSM or NLC-COM-CELLULAR-CDMA module is installed, some flags
may be used for other purposes. Refer to the NLC-COM-GSM user manual for GSM flags.
