We have 4 Mettler Toledo Viper SW weighing scale with only RS232C ports. We want to interface the scale to a single PC and send the data into Wonderware INSQL residing on the same PC. I understand that we cannot multidrop RS232C and need to have RS422 or RS485. Is there a PC card with RS422 or RS485?. I suppose we still have to convert the RS232C signals from the weigh scales into RS422/485 using a converter. We also need either a DDE or OPC I/O server on the PC talking to the 4 Mettler scales.
Any ideas to go about getting the above job done is appreciated. Also my budget is very tight.
Thanks.
