It can be used as the ModbusTCP client, providing the interface of SIEMENS PLC for the upper software with ModbusTCP protocol. For example, if you want to read the data in SIEMENS PLC through Modbus TCP, you can read the data in PLC with C first, then read the data in C from Modbus master station. It can realize communication between SIEMENS PLC, including S7-200, 300, 1200 and 200smart.
The C type has the same storage area as 200PLC, and is a 200PLC without IO points.
The number of ModbusTCP connections and the number of PLC communication channels can be established by C products.
The C type can build 12 ModbusTCP connections at the same time, and has 12 PLC communication channels (the maximum 200 bytes of each channel, supporting data / sending data).
