Hi Guys!
Since I have been a fix with protocols not being the same before, I'll ask if any of you have ever tried this combination:
I have a system with a 1756-L62 CPU and a 1756-ENBT Ethernet module.
On this system I have 17 silo's that needs a new level meassurement, and for this I have chosen VEGAFLEX 61. To cut down the number of analog inputs required, the vendor suggests that I use a VEGASCAN 693. This scanner can read up to 15 sensor values over a single 2-wire cable - neat!
But it communicates over Ethernet using Modbus protocol, and this is where I start getting nervous ;-).
Is this modbus protocol the same as what the Logix platform uses and can it communicate with the scanner at all?
Regards,
Michal Rudbeck-Rønne
