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.
Modsak Manual v3.16 - 5. Commands
Modsak provides two ways of sending commands to a Modbus slave when you are using master mode or monitor mode.
If you have defined some Modbus registers, you can use the Read, Write and Poll buttons to send requests to the slave.
Alternatively, you can define and send Modbus commands using the Define Command page, as described in the next section. These commands do not use register definitions.
