7.2.17 MODBUS Mode
Use the MODBUS mode setting to activate or de-activate the DLCM’s ability to follow a MODBUS
serial signal. If deactivated, the MODBUS mode will not appear when [MODE] is pressed. If you are
not using the serial input (i.e., you have made no connections to J7 or J8) but have the MODBUS mode
set to active, then any time you mistakenly press [MODE], by default the DLC will generate a
{MODBUS SIGNAL FAILURE} alarm. De-activating MODBUS mode prevents this.
The [MODE] key allows you to select an operating mode. It acts as a master switch allowing you to
select what signal controls the DLCM. It does not inhibit MODBUS communications. It only inhibits
MODBUS commands that pertain to the operation (e.g., you cannot turn the pump motor on using
MODBUS unless the mode is set to MODBUS).
