The "Modbus_Master" instruction uses a "MODE" input instead of a function code input. The combination of "MODE" and "DATA_ADDR" defines the function code that is used in the actual Modbus message. The "DATA_ADDR" parameter consists of the address in the Modbus slave and an offset.
With Ident Profile and the AdvancedCmd block it is possible to send chained commands. Chained commands are sent completely to the reader without waiting for the result of the first command. This function makes it possible for you to execute different transponder commands with one single command start.

Microsoft regularly rectifies security gaps in its products and makes these fixes available to its customers in the form of official patches.
The properties of the open IE communication via the integrated PN/IE interface of the CPU and via Industrial Ethernet CP are explained below.
The correct battery pack as a spare part for the Field PG M3 or M4 is currently the SIMATIC Field PG M5 battery pack. This type of battery pack requires you to do a BIOS update.
Calling "gpedit.msc", the editor for local group policies, can lead to an error message of the administrative templates after the initial start or after a reinstallation of the MUI operating system.
The IOP (Intelligent Operator Panel) has been available for delivery since 2009. Since this time the operator panel has been supplied with different software versions.
The attached table gives you information about compatibility between Microsoft Windows operating systems and the SIMATIC NET PROFIBUS PC CPs.
If you have addressed a technical query about COMOS to Support, a COMOS log file is often required for the Support Request. Here we describe how to create a COMOS log file. Support can better analyze the matter with the COMOS log file and perhaps work faster.
A combination encoder, which sends an HTL signal for the speed control and an SSI for the position control, is to be connected to a CU250S. The HTL signal is to be connected through terminals - while the SSI is to be connected through a D-SUB interface. A Y cable from the Knorrtec company is used to establish the connection.
With a SCALANCE W that is parameterized as WLAN client you can set 4 different MAC modes. The MAC mode decides how the WLAN client behaves with respect to the Access Point and whether the PROFINET connection to the distributed IO can be established.
This entry provides information on the replacement of circuit breakers following short-circuit tripping operations.
This entry gives you sample applications for Modbus/TCP communication via the integrated PROFINET interface of the S7-300 and S7-400 CPUs as well as the IM 151-8 PN/DP CPU in the TIA Portal.
This entry includes a list of all the products and PCS 7 components which you can install using the SIMATIC Management Console and which have been tested and released in the PCS 7 environment.
