MODBUS PROTOCOL FOR COMMUNICATION BETWEEN CARDS 9010/20LCD AND SUPERVISION UNIT
1.0 GENERAL
Communication between cards 9010/20LCD and any supervision unit occurs through serial communication in RS485 using the MODBUS protocol with RTU transmission mode. All cards 9010/20LCD are slave whilst the supervision unit is master. Slaves are peripheral with address from 1 to 255.
Transmission is fixed at 9600 bit/s, one stop bit and no parity.
9.0 LIST OF WORDS AND THEIR MEANING
Addresses of all words are shown with their mnemonic name, an explanation of what they represent and the kind of operations that can be carried out (reading, writing, reading and writing).
