Electronic coupler 600-151-1AA11

PROFIBUS-DP busI/O

A functioning TB20 configuration will always require a bus coupler and at least one peripheral module. The PROFIBUS-DP bus coupler is designed to connect a PROFIBUS bus to TB20 peripheral modules. It supports the DP-V0 and DP-V1 protocols. It will recognize all connected peripheral modules and assign each module the corresponding inputs/outputs from the process image table. A functioning TB20 configuration will always require a bus coupler and at least one peripheral module, but can accommodate up to 64 modules of any kind connected in series with the bus coupler. The bus coupler supports hot-swap for replacing modules during operation. Bit packing: Starting with firmware version 1.20, the states of 2-bit and 4-bit I/O modules can be packed together in bytes, making it possible to take full advantage of all the space in the process image table. Parameters Diagnostic alarm: On | Off Process alarm: On | Off Pull/plug alarm: On | Off Startup when expected/actual configuration differ: On | Off (hot-swaping allowed: Yes | No) Identifier-related diagnostics: On | Off Submodule status: On | Off Channel-related diagnostics: On | Off
