Dear Viewers / Readers / autmation Engineers
Suggestions are required from every positive expert of PLC system engineer.
We the representative of autmation department of a Cement Industry.
Brief view of autmation of our industry is as under:
We have total 12 Nos. of main PLC of Modicon 984-785 series with 800 series I/O modules & Racks. All these PLCs are connected to Modbus Plus Network through Modbus Plus Network Rack Module / Card ( type : S985-800).The programming of these PLCs is done in Ladder Logic through Modsoft Programming software v2.6 ( DOS based ).Many Builtin Functions FB/FN are used for progarmming of Unidirectional motor ( FN 99 , Bidirectional motor (FN88) , Select switch point (FN 87) , Motor Group Controller (FN98) , 3 point PIDs ( FN 96 ) , Continous output PID (FN 90) , Alarm Handler (FN 91 ) , Gate Controller (FN 78) and many more.
All These PLCs are communicating to HMI / ECS system through PC Host PCI adaptor ( Type : 416 NHM30032).
Now we are planning to change our system with less shutdown time & fast conversion of existing system program to new PLC progarm.
Initially we are planning to use Modicon Quantum series PLC' CPU witout changing the 800 series I/O modules.
So suggestions are required what hardware changes we have to consider if we only want to change CPUs and Modbus network Cards and bring it to Ethernet. what software changes we have to take into account if we just want to have old project file conversion system ( from Modsoft 2.6 to window based Unity Pro software )... is it possible to do such file conversion, without doing any big programming as we want to avoid reinvetion of wheel i.e we want to avoid redo of the programming of whole plant.
Does Modicon new software like unity pro support such converion. What hardware compnents we have to take into account for CPU to commuincate to Etherent and to Commuicate with exisiting I/O Racks and Modules of 800 series.?
Please feel free to get any futher informations( [email protected])
