IO-Link
IO-Link family
IO-Link is an open communication standard for sensors and actuators – defined by the
IO-Link Consortium.
2/101
• Dynamic changing of sensor/actuator parameters directly by the PLC
• Devices can be exchanged during operation, without a PC or programming device,
through re-parameterization using the user program by means of a function block (FB)
or parameter server
• Fast commissioning thanks to central data storage
• Consistent diagnostic information as far as the sensor/actuator level
• Uniform and greatly reduced wiring of different sensors/actuators/controls
Your advantage: Fast commissioning and flexible maintenance thanks to central data
storage, less wiring work because no passive distributors are needed.
IO-Link: Masters
The IO-Link master modules form the heart of the IO-Link system.
SM 1278 4xIO-Link
for SIMATIC S7-1200
IO-Link master module for SIMATIC S7-1200
SM 1278 4xIO-Link Master
• IO-Link master as serial communication module with four ports (channels) according to
IO-Link Specification V1.1
• Easy device exchange with automatic data recovery without engineering for IO-Link device
• Up to four IO-Link devices (3-wire connections) can be connected to each IO-Link master
module
•
Data transmission rates COM1 (4.8 kBd), COM2 (38.4 kBd), COM3 (230.4 kBd), automatic
adjustment to the data transmission rate supported by the device
Your advantage: easy connection of IO-Link connections to the SIMATIC S7-1200.

CM 4xIO-Link communication module
• IO-Link master as serial communication module with four ports (channels) according to
IO-Link Specification V1.1
• Module replacement with automatic data recovery without engineering for IO-Link master
and device
• Up to four IO-Link devices (3-wire connections) can be connected to each IO-Link master
module.
• Data transmission rates COM1 (4.8 kBd), COM2 (38.4 kBd), COM3 (230.4 kBd),
automatic adjustment to the data transmission rate supported by the device
Your advantage: easy connection of IO-Link connections to distributed I/Os.
