If parameter internal type is int32 or uint32 then register is calculated as:
•
Values - Comma separated integers, parameter internal values, and comparisons
using the >, >=, <, <=, and <> operators.
Note: It is possible to list multiple registers and multiple possible identification values
for each register. However, the increase in conditions makes the identification slower
and further slows the automatic identification performance (Modbus background
scanning). Hence, it is recommended to use maximum 3 conditions.
States
States tab includes the Modbus register information that is mapped to the Modbus
template and also indicates the device status.
States tab has the following components:
•
Name - Displays the device status. For example, Disconnected, fault, warning,
and so on.
•
Parameter - Displays the related parameter in group.index format.
•
Mask - Unsigned integer. Defines the value of bitmask for comparison
operation.The mask value is calculated as:
where 0, 1.....n are the bits in a bitword.
Note: You can enter the mask values as decimal number in different formats. For
example, 123, 0x7B, 0b1111011, and so on.
•
Operation - Triggered automatically if NETA - 21 cannot read any values. The
possible events and its reasons are:
Operation Reason
No response NETA-21 cannot read any values.
Value column and mask can be
empty, but the parameter must be
an existing parameter which can be
always read if the device is con-
nected (preferably main statusword
which is also used for fault and
warning states)
