Product Overview
The B2341 programming environment is Codesys, a programmable controller that
follows the IEC61131-3 international standard, and supports five programming
languages: ladder diagram (LD), instruction list (IL), structured text (ST), function
block diagram (CFC), and sequential function diagram (SFC).
The maximum number of expansion modules is 4, the user program storage supports 1 Mbytes,
the power-down protection zone is 4 Kbytes, and Modbus TCP client and server are supported.
It has rich instructions, reliable functions, good adaptability, compact structure, easy
to expand, cost-effective, strong versatility, programming, monitoring, debugging, and
on-site operation are very convenient, and the Ethernet interface on the CPU supports
Modbus TCP client function, and supports access to the data of the third-party
Modbus TCP server.
Supports Modbus TCP server function and supports third-party Modbus TCP clients to access data.
Supported I/O expansion modules include:
A. Digital input module
B. Digital output module
C. Analog input module
D. Analog output module
E. Special function module
