Hello; It is possible to use a CP 341 as a Modbus RTU master (it will then communicate with a Modbus slave, what equioment are youplnnng to send th alarm ata to?). But you will need to purchase a rather expensive license to do so. You will find the manaul for this driver and how to manipulate the special blocks for Modbus RTU here: https://support.industry.siemens.com/cs/ca/en/view/1220184 The S7-1200 and S7-1500 families of processors are more modern and integrate Modbus RTU masterr and slave functions directly in the programming software (TIA Portal v1x) so it coud be much less expensive and a lot easier to implement your task. Check out the software requirements for communications over Modbus RTU using the S7-300 and the CP 341 first. we can then discuss the collecton and transfer of alarms as a next step. Hope this helps, Daniel Chartier |
