Hi,
i have a project where a simple step by step program has been created for a batching process eg.a recipie is selected and then an ingredient is displayed on HMI and the weight ect, the operator the weighs the ingredient and once completed it roll over to the next ingredient, and then loggs the data on PC via OPCand It works fine. i now need to create one for many more recipies. Currently i am using a mIicrologix 1500.
I have bought a ML1400 and we were considering connecting the using DH485 and one plc hold the recipies and ingredients data
while the ML1500 will hold the basic data from scale ,storing barcodes ect.
I have researched that the communication is done using the MSG function but need to understand more about it,first.
As an alternative i was wondering if it is possible to have a PC connected using maybe OPC and the PLC talks to to the PC and aquires its recipe data from it maybe from Excel or SQL, if a data table was created. is this possible at all ?
ThaNks in advance
