a. A write to the Identify module register will cause the module to perform the identify operation which may be a steady
LED for a few seconds or a beep in the Field Wizard.
b. Setting the Take Reading flag to 1 will cause the module to update the registers with current data readings. It will
be set to zero when the readings have all been updated. This may be used to initiate readings and poll for when
they are ready to be read. It may take up to 50 seconds to update all the readings, depending upon the flow condi-
tions. Setting the Take Reading flag to 2 causes an automatic, 15 second update of readings when a Modbus mas-
ter is polling the 2100.
c. The Update Interval specifies an interval in seconds that the registers are automatically updated. It defaults to zero,
which indicates that no automatic updating will occur.
d. The Active Flag (1-4) bit fields specify what fields/registers are active in the list. This provides support for a maxi-
mum of 64 fields. For example, if bit 0 of register 27 is set, the Level (registers 40,41) is active. If bit 1 of register
27 is set, then the Velocity (registers 55,56) is active. If bit 0 of register 28 is set, the Analog channel 7 (registers
265,266) is active.
e. A non-zero status code indicates a measurement problem.
f. Time is represented in a series of registers: Order is from lowest address to highest - Seconds (0-59), Minutes
(0-59), Hours (0-23), Days (1-31), Month (1-12) and Year (1977-2099).
g. Optional software feature. Contact Teledyne Isco to order enable code for the module used for communication.
