Key issues

Question 1: What is the maximum number of discrete I/O points supported by TSX 47 series PLC? Which models can reach the maximum value?

Answer: Supports a maximum of 256 discrete I/O points; The models that can reach the maximum value are TSX 47-10, TSX 47-20, and TSX 47-25.

Question 2: What is the program storage solution for TSX 47? What are the contents stored in internal RAM and external program cards respectively?

Answer: Adopting dual storage of internal RAM and plug-in program card; Internal RAM stores process data, bit/word variables, system status, and battery backup for 5 weeks; The program card stores user programs and constants, with a capacity of 8-32KB and optional RAM or EPROM.

Question 3: What are the dual task structures of TSX 47? What are their respective roles and refresh cycles?

Answer: Dual task main task and fast task; The main task is a non periodic task used for sequential logic, with a watchdog of 150ms; the fast task is an optional periodic task used for high-speed signal processing, with a cycle of 5-10ms, and only supports ladder diagram programming.
