Hi,
I'm currently developing a project that uses the following hardware/software:
- PC;
- LV16;
- DSC Module;
- Micrologix 1400 PLC.
My goal is to read only two addresses in the Micrologix 1400: N10:5 and N10:8. As far as I have searched, there are 3 ways to develop the communication:
- OPC Server;
- MODBUS;
- TCP/IP.
The first option, OPC Server, is out of question, because of limited budget. However, everytime I search for a guide, I end up in a solution that uses OPC Server. The only solutions that do not use OPC Server are not well explained.
So, my questions are the following:
- Can I use MODBUS to communicate my PC with my PLC?
- If yes, how do I map the tags and the addresses, i.e, in this example, NI explains how to set up a communication. However, it does not specify how I can map the address with the register. Like, I want to read the N10:5 value, how do I set up this configuration?
- Can I use TCP/IP?
- If yes, how do I map the tags and the addresses?
It is important for me to only use the softwares/hardwares I described above, any other purchases are out of question.
Kind regards,
André Kruger
