What do MSTP, IP/TCP, and RTU mean?
These are all different types of transmission modes or communication protocols that Setra's products use when connected to Modbus, BACnet, or another network. A transmission mode is the mechanism of transferring data between two devices connected over a network.
A few examples include the following:
Transmission Control Protocol/Internet Protocol (TCP/IP)
- This communication protocol uses an IP address to identify unique devices on a network. IT will typically be used in a network that uses ethernet cables.
Master-Slave/Token Pass (MSTP)
- This communication protocol uses MAC addresses and establishes a pecking order for the devices on a network.
- This refers mostly to the type of cable used and can be used in conjunction with other communication protocols.
These are some but not all the way to get data from one location to another. Each has its own structure that needs to be configured, but they all serve the same purpose.
