There is one potential pitfall:the default baud rate for DH485 is 19200, and this is what you will find most of the time. However, it is possible to configure it in the PLC settings to be 1200, 2400, or 9600 baud at as well. The 1747-UIC adapter only supports 19200 baud out o...
OPC Router replaces old communication channels – up to the complete integration of PLC (Programmable Logic Controller), DCS (Distributed Control System), SCADA, MES (Manufacturing Execution System), SQL Server, label printers, email server and ERP systems. The Router as a central communication pla...
So we have to create 2 buffers, in this case both of the same length, and we create an S7MultiVar variable. The S7MultiVar variables have a method “Read”, which populates all the buffers with the data from the plc. This is the code to make the read: 1 2 3 4 5 6 7 8 9 ...
To read for example 18 bytes, we need to create an array of 18 bytes. Then pass it to the Read function to populate it with the data from the cpu, then convert all the data from S7 format to C# format. For example this is the code to read this DB: ...
enabled, a conversion can be performed. If the RTD is shorted, a conversion result close to 0 will be obtained. An open wire between AIN+ and AIN– will result in a conversion close to 0xFFFFFF. With the RTD correctly connected, a code close to 0 or all 1s should never be obtained...

PLCs require computer code to operate and run. Access to PLC computer modules normally requires a username and password. Recently, researchers discovered a vulnerability inYokogawa Corp.'s Stardom PLCin which the username and password are hard-coded in the system and can enable attackers to ...
A third category, medium-interaction honeypots (Mokube and Adams, 2007), does exist but its characteristics lay close to a low-interaction variant. Low-interaction honeypots pretend to be a specific device such as a Programmable Logic Controller (PLC) and mimic its functions, they run on a ...
