FAQ

Question?

What is the function of the included 6ES5 491-0LB11 casing?

The 6ES5 491-0LB11 is an adaptation casing. The CP 1430 module has a compact form factor that does not directly fit into the larger slots of a SIMATIC S5-135U or S5-155U central rack. This casing adapts the module to the correct size and bus connection for these specific PLC systems.

Question?

What software is required to configure the 6GK1143-0TA02?

Configuration of the CP 1430 TF is typically done using the Siemens NCM COM 1430 software package, which runs on a programming device compatible with the SIMATIC S5 environment, such as a PG with STEP 5.

Question?

Is this module compatible with modern Profinet networks?

No, this is a legacy module that communicates using the SINEC H1 protocol over Industrial Ethernet. It is not compatible with modern Siemens protocols like Profinet. For Profinet connectivity, a system migration to a modern platform like SIMATIC S7 is required.
