For SIMATIC ET 200SP, two types of BusAdapter (BA) are available for selection:
ET 200SP BusAdapter "BA-Send"
for expansion of an ET 200SP station with up to 16 modules from the ET 200AL I/O series with IP67 protection via an ET connection
SIMATIC BusAdapter
for the free selection of the connection system (pluggable or direct connection) and physical PROFINET connection (copper, POF, HCS or glass fiber) to devices with a SIMATIC BusAdapter interface.
One further advantage of the SIMATIC BusAdapter: only the adapter needs to be replaced for subsequent conversion to the rugged FastConnect technology or a fiber-optic connection, or to repair defective RJ45 sockets.
Application
ET 200SP BusAdapter "BA-Send"
BA-Send BusAdapters are used whenever an existing ET 200SP station is to be expanded with IP67 modules of the SIMATIC ET 200AL.
The SIMATIC ET 200AL is a distributed I/O device with degree of protection IP65/67 that is easy to operate and install. Due to its high degree of protection and ruggedness as well as its small dimensions and low weight, the ET 200AL is especially suitable for use at the machine and on moving plant sections. SIMATIC ET 200AL enables the user to access digital and analog signals and IO-Link data at low cost.
SIMATIC BusAdapters
In standard applications with moderate mechanical and EMC loads, SIMATIC BusAdapters with an RJ45 interface can be used, e.g. the BusAdapter BA 2xRJ45.
For machines and systems in which higher mechanical and/or EMC loads act on the devices, a SIMATIC BusAdapter with connection via FastConnect (FC) or FO cable (SCRJ, LC, or LC-LD) is recommended. Likewise, all SIMATIC BusAdapters with a fiber-optic cable connection (SCRJ, LC) can be used with the increased loads.
BusAdapters with connections for fiber-optic cables can be used to cover high potential differences between two stations and/or high EMC loads.
