When establishing a connection to an OPC UA server you should observe a number of points to make the process run smoothly.
An update is needed for each version of the certificates used for signing the Windows files of the SIMATIC S7-1500 software controller.
The attached PDF document gives you detailed information.
If you configure the ET 200SP IM155-6 PN/DP incl. server module in the TIA Selection Tool and then import it into EPLAN via the AutomationML PLC data exchange format, then in the EPLAN parts list, in addition to the article number of the IM155-6 PN/DP (incl. server module) you see another article number 6ES7193-6PA00-0AA0 for the server module (spare part).
Please not the following information about arrays and the data types DTL/LDT in connection with the OPC UA server of a SIMATIC S7-1500.
If you configure an OPC UA client incorrectly you can unnecessarily load or even overload the OPC UA server of a SIMATIC S7-1500 CPU or the OPC UA communication.
An overview shows which PROFINET functions you can configure in STEP 7 (TIA Portal) for the PROFINET IO controllers and IO devices.
Discover without time-consuming searching in the manuals the forms in which SIMATIC HMI products and SITOP products support OPC UA.
You cannot compile know-how-protected blocks if they are not released for use in a library.
In STEP 7 V14 (TIA Portal) and higher the "Modbus_Master" instruction provides with V2.4 and higher for SIMATIC S7-1200/S7-1500 the option of reading out the extended address range (9999 - 65535) of input words (function code 04) of a Modbus slave.
An overview shows the properties, advantages and special features of the protocols TCP, ISO-on-TCP, UDP and ISO Transport.
If you are using a software controller on a SIMATIC IPC without NVRAM, it might happen that if the IPC is not shut down properly, there is data loss, the absolute value encoder adjustment, for example.
Open Source Software parts and conditions of use of the SIMATIC apps for downloading
Connect the channels (Mn- - connections) of the analog modules "AI 4xRTD/TC 2-/3-/4-wire HF" and "AI 8xRTD/TC 2-wire HF" with a common reference potential.
Automatic commissioning (device replacement without interchangeable medium) with topological configuration and device replacement without topological configuration?
STEP 7 Professional / Basic projects from earlier versions of the TIA Portal (before V13 SP1) have to be upgraded to the latest version before being opened.
The following tables give you the system limits of the OPC UA Server with S7-1500 CPUs, ET 200 CPUs, Software Controllers and Open Controllers.
The following table gives you the necessary information for the S7-1500 CPUs, ET 200 CPUs, Software Controllers and Open Controllers.
Consider the subsequent restrictions in the S7-1500 CPU with firmware V2.5, if the CPU configured in one of a early version (< V15) in the firmware V2.0.x oder V2.1.x.
Downloading of the project data to the S7-1500 CPU is aborted if the maximum number of configurable program alarms in your STEP 7 (TIA Portal) project is exceeded.
