Hello,
How can I establish a modbus communication between a PC and a S7-300. The PC should be master and the S7-300 slave.
For the Simatic I'll need a CP341 WITH RS422/485 and a SIMATIC S7, MODBUS SLAVE V3.1 SINGLE LICENSE.
What do I need for the PC side?? A PC card?? A modbus softnet? Do we have a modbus softnet?? I'd like to read the PLC data on Visual Basic 6.0
Thanks in advance
