EM 277 PROFIBUS-DP Module is an intelligent expansion module which connects S7-200 CPU to PROFIBUS-DP net by Serial I/O
Detail description
As a DP substation, EM277 Module receives different I/O configurations from main station, sends and receives different quantites Data, it is convenient for customer to revise the transferred data to suit for the request of practical application.
Advantage
1. Support S7-200 PLC( such as CPU 224, 224XP)
2. Support S7-300 CPU with DP main station function
3. RS-485 communication and self suit for 9.6kbps-12mbps
4. Max. support 99 DP substations
5. RS-485 port with Photoelectric isolation, over-current protection
6. Power supply with reverse connection protection and surge absorption.
