IPLOG in the license plate reader application

IPLOG controllers have a wide range of function blocks for creating user programs. These include Wiegand blocks, TCP events, format conversion blocks. When connected to a registration tag reading application running on IP cameras, the IPLOG can transfer this data to various access control systems or process it directly in the IEC program.

‌

Prerequisites:

• Camera: any camera with a license plate reading function, in this example it was a Mobotix camera
• IPLOG: any type of IPLOG with wiegand interface (IF-11), FW version 12.0.14297 and higher
• ACS: in this example it was Roger

Function description
The camera captures the registration mark and sends the data to the IPLOG unit. The camera is in TCP server mode and IPLOG is in TCP client mode. The IPLOG unit modifies the received data in its program (removes unnecessary characters) and encrypts the result using the SHA-1 algorithm. It takes the last 6 characters from the hash and sends them to the wiegand interface.
