registers to support the number of alarms. Example: If the total number of alarms was
64, it would show four 16 bit registers.
4. Total No. of Controls
Enter the total number of Pushbutton Controls up to 16. Once this is entered, it will add
an extra Modbus register at far right of table.
5. Set Up the Modbus Mapping for Alarm Inputs
For each 16 bit Modbus registers enter a single input number or group of inputs with
commas to separate inputs (1,2,3,4 etc) or dashes (1-4) for a group of alarms or
combinations of both (1-4,5,9). Up to 32 digits may be entered including commas and
dashes. When selecting a group of alarms for a single Modbus bit, it will act as a Logic
OR which will activate an alarm when any of the inputs goes into the alarm state and
stay activated until all inputs in the group return to normal.
6. Set up the Modbus Mapping for Control Pushbuttons
If Control Inputs are used, the last 16 bit register is used for this set-up. For each bit
position, you can assign the function, control group 1 and whether it is being transmitted
from the DMS-3K to the Modbus Device or received from the Modbus Device. When
selecting the controls, they will be labeled as follows:
Function
Full Function Test (T)
Lamp Test (L)
Acknowledge (A)
Reset (R)
First Out Reset (F)
Silence (S)
Inhibit (I)

+ = transmit,
- = receive
This refers to whether
the control is
transmitted via one of
the control inputs or
received through the
serial communications.
