Hello gents,
I have an application where the cheapest communication link available is a radio telemetry system that works off of RS-232 protocol.
Our site only uses AB and looking into their catalog, it seems like there isn't many options for PLC's with Serial ports.
Do you guys still use them or how can I get around this? For one or two of the applications, a sort of gateway PLC would be feasible to collect all the data required from the installation (consisting of multiple PLCs) and sending it over the link. But on remote systems that have only one PLC, having a separate one just for a serial port is a bit of a waste.
Any ideas? I know there's some sort of Serial Port converters out there, but I personally prefer to have all enclosed as much as possible.
