Dear all,
i have a project to make a connection between PC-Radio modem-PLC-Motor.
i already connect it all together, now my problem is i have to make man machine interface to control the PLC. To make an mmi i have to understand modbus communication for receiving and sending datas. I already understand the modbus concept to use in twido plc, but if i want to control from the PC it's very hard. The data that i send from the PLC is very different with the data that i receive in pc. i'am also don't know how to send datas that could be understand by the plc with modbus communication.
Please help me to solve this problem...
thanks
best regards,
hosana
