PROFINET IO
6.1 General
With the COM190 communication module, you can access the data of the 3WA circuit
breakers via the PROFINET IO during operation. The PROFINET IO can be operated in parallel
with the Modbus TCP protocol (see Chapter Modbus TCP (Page 35)).
Overview
The COM190 communication module has the following performance features:
• Direct connection between further Ethernet nodes by two integrated switched Ethernet
ports into the IRT domain of PROFINET
• Highest conformance class (Conformance Class C) and highest netload class (Netload
Class III)
• Support for ring redundancy (MRP) by the integrated switched Ethernet ports
• The SENTRON devices communicate directly with SIMATIC S7 and SIMOTION via
PROFINET IO.
• The COM190 communication module as the PROFINET IO device makes metering values
and statuses of the 3WA circuit breakers available to the PROFINET IO controller. The
module receives information (e.g. commands) from the PROFINET IO controller and
forwards this information to the 3WA circuit breaker.
• Thanks to the support of PROFINET IRT, the 3WA circuit breakers can be used without
restriction directly in production automation networks (e.g. alongside SIMATIC S7,
SINUMERIK, SINAMICS and SIMOTION).
• Simple engineering with SIMATIC STEP 7 V5 or other programming systems thanks to the
use of the GDSML file
• Optimal use of the process image of a controller thanks to the selection of individual
metering variables
• Support for the "Low Voltage Switchgear" (LVSG) PROFINET profile
• Application-specific Energy Suite profiles (e0 to e3) for energy management in cyclic data
• Reading and querying of metering variables of the 3WA circuit breaker via the
"Query_Measurement" service of the PROFIenergy standard
• Use of all the functions of the 3WA circuit breaker, use of the powermanager and
powerconfig software either independently or in parallel with PROFINET IO
• Support of 100 Mbit/s data rates on both RJ45 interfaces
• Time synchronization via SNTP
