New modules for the S7-1200
New modules expand the power of the S7-1200 CPU and provide the flexibility to meet your
automation needs:
● New CPU 1217C DC/DC/DC (Page 879) with high-speed differential points
● New and improved S7-1200 signal modules. The new signal modules (6ES7 2xx-xxx32-
0XB0) replace existing signal modules (6ES7 2xx-xxx30-0XB0). The new modules
provide:
– 4-20 mA range added to analog input and output modules
– Wirebreak detection when using 4-20 mA added to analog input modules
– Connector keying to prevent errors when plugging in field wiring connectors added to
modules with relay outputs
– Spare parts compatibility: you can employ the revised module in place of existing
modules without any changes.
● New spare parts (Page 993) available for use with S7-1200 CPUs
● New CPU 1217C Input Simulator (Page 978) (6ES7 274-1XK30-0XA0)
● New SM 1278 4xIO-Link Master (Page 815) (6ES7 278-4BD32-0XB0) functions as both a
signal module and a communication module, and allows connection of up to 4 IO-Link
slaves (3-wire connection) or 4 standard actuators or standard encoders
● New S7-1200 Potentiometer module (Page 980) (6ES7 274-1XA30-0XA0)
● New CM CANopen for S7-1200 (Page 983) is a plug-in module that allows you to connect
CANopen devices to the S7-1200 PLC. It can be configured to be both master or slave.
Exchanging your V3.0 CPU for a V4.0 CPU
If you are replacing an S7-1200 V3.0 CPU with an S7-1200 V4.0 CPU, take note of the
documented differences (Page 995) in the versions.
