Is there just one standard concerning Modbus TCP/IP?
If you compare this quote:
with this one:
If you compare this quote:
The MODBUS/TCP protocol uses binary encoding of data and TCP/IP's error detection mechanism for detection of transmission errors.
with this one:
MODBUS TCP/IP is essentially the serial MODBUS RTU protocol encapsulated in a TCP/IP wrapper.
It appears to be two different standards.
One flavor appears to be standard Modbus/TCP and the other appears to be Modbus RTU over TCP/IP.
Is there a difference?
Can somebody clarify this for me?
Thanks.
