Product Description

 

Product Description

Order No.: CTH2 277-0AB32
Specification: SM277B Profibus DP slave module, 1.5M, optoelectronic isolation

Both SM277A and SM277B adopt photoelectric isolation technology, with high reliability and strong anti-interference ability. These two modules are equipped with terminal resistance, bus connection, no need for special network connector. Its power supply has the function of reverse connection protection and surge absorption, and can be used in harsh working environment.
However, SM277A needs to cooperate with the CPU, while SM277B can be used as a standalone slave station with six extension modules, the scale of slave station I/O up to 128DI/128DO, 48AI/24AQ.

Set PROFIBUS address
You can use DIP switch to set PROFIBUS address. Cut-off and recycle the power of SM277B module to make them effective after you change the address.
DIP switch SW1-8 (in binary), SW1 for the LSB, SW8 for the MSB (must be "OFF"), SW1-SW7 set as "ON" - "1", "OFF" - "0", calculated as following:
Address =SW1×2⁰+ SW2×2¹ +SW3×2² +SW4×2³+ SW5×2⁴ +SW6×2⁵ +SW7×2⁶
