Please. I have a PLC I've been working that does a lot of number crunching. Every hour or so it produces a single number of interest that I'd like to transport to a spreadsheet. I contacted the manufacturer (WAGO) and they suggested I communicate via Modbusâa protocol I'm only vaguely familiar withâusing TCP/IP. I've used Modbus to communicate from the PLC to a panel, but honestly the protocol was handled automatically. Now I'm looking to purchase a Modbus DLL driver for a few hundred dollars, but I'm unsure if I'm buying the Master or Slave driver. I think the Master, but could someone please clarify this? Otherwise I'm really unsure, frankly, how to really begin, or if I'm even starting in the right direction. Does Real Studio have any innate communication ability with Modbus, or do I need to buy the driver? Is there any "heads-up" I should be aware of when going this method? Any advice is greatly appreciated. Thanks! _________________ Vista Home Premium RB Pro 2009r3 "Christianity has not been tried and found wanting; it has been found difficult and not tried." - G.K.
