Using Modbus/TCP Function Codes 4-11
20-COMM-M Modbus/TCP Adapter User Manual
Publication 20COMM-UM014C-EN-P
Reading Device Parameters
1. Verify that the Unit Identifier is set to “0” (zero) or “16.”
2. Using Table 4.J
and its associated formula, determine the value to use
for an adapter Indirect Par #x that points to the specific device
parameter you want to read. For example, suppose adapter Parameter
38 - [Indirect Par #1] is used and you want to read drive Parameter 003
- [Output Current] or drive Parameter 012 - [DC Bus Voltage]. In this
case, set adapter Parameter 38 - [Indirect Par #1] to a value of “3” or
“12” respectively.
3. Use Function Code 03 or 23 (Table 4.A
) to read the value(s) of specific
device parameter(s). For this example, read register addresses 10041
and 10042 for adapter Indirect Parameter #1 Data as shown in
Table 4.K
.
