Wingpath to cease trading on 25 October 2025
From 25 October 2025 we will no longer be selling licences for our software products (ModSnmp, ModMultiSim, Modsak, ModSlaveSim, ModMaster and ModTest).
The website will remain operational until at least 2027 for reference purposes, and for the registration and transfer of product licences.
ModMaster Manual v3.16 - 5.1.1.3. Read Device Identification (43/14)
The Read Device Identification command reads identification "objects" from the slave.
Code. Select the required access type: Basic, Regular, Extended or Specific. Specific is used to read a single identification object. The other access types limit the range of objects returned.

First Object ID. Enter the ID of the first object to be requested. If you are using the Specific access type, this will be the only object read.
The ID should be in the range 0 to 255. Although not required by the Modbus specification, the ID would normally be restricted to the range 0 to 2 for Basic access, and to the range 0 to 127 for Regular access.
