CM 1542-1
The communication module CM 1542-1 expands an S7-1500 control system by a
PROFINET connection which is implemented as a 2-port switch with 10/100 Mbps. With the
CM 1542-1 as a PROFINET controller for up to 128 PNIO devices, a separate PROFINET
segment can be set up. As IT functions HTTP and e-mail are available. The redundancy
protocol MRP is also supported (MRP manager and MRP client). The configuration is
created with STEP 7 Professional V13 or higher.
The figure shows an application example of the network separation with an CM1542-1:

CP 1543-1
This communication processor CP 1543-1 connects an S7-1500 controller to an Ethernet
network. It has proven security mechanisms (including firewall with Stateful Packet
Inspection, VPN with IPsec, IP/MAC Access Control List, FTPS) to protect individual devices
or entire automation cells from unauthorized access. Data transmission rates up to 1000
Mbps and common IT functions such as FTP, HTTP and e-mail are supported. For
configuration, the TIA Portal as of Version 12 is used.
The SIPLUS product variant comes with coated PCBs (conformal coating) and is designed
for usage in extended temperature ranges -40 °C to +60 °C.
